Office of Inspector General; Medicare Program; Prospective Payment System for Hospital Outpatient Services
AGENCY:
Health Care Financing Administration (HCFA), HHS, and Office of Inspector General (OIG), HHS.
ACTION:
Final rule with comment period.
SUMMARY:
This final rule with comment period implements a prospective payment system for hospital outpatient services furnished to Medicare beneficiaries, as set forth in section 1833(t) of the Social Security Act. It also establishes requirements for provider departments and provider-based entities, and it implements section 9343(c) of the Omnibus Budget Reconciliation Act of 1986, which prohibits Medicare payment for nonphysician services furnished to a hospital outpatient by a provider or supplier other than a hospital, unless the services are furnished under an arrangement with the hospital. In addition, this rule establishes in regulations the extension of reductions in payment for costs of hospital outpatient services required by section 4522 of the Balanced Budget Act of 1997, as amended by section 201(k) of the Balanced Budget Refinement Act of 1999.
DATES:
Effective date:
July 1, 2000, except that the changes to § 412.24(d)(6), new § 413.65, and the changes to § 489.24(h), § 498.2, and § 498.3 are effective October 10, 2000.
Applicability date:
For Medicare services furnished by all hospitals, including hospitals excluded from the inpatient prospective payment system, and by community mental health centers, the applicability date for implementation of the hospital outpatient prospective payment system is July 1, 2000.
Comment date:

I. Background
A. General and Legislative History
When the Medicare program was first implemented, it paid for hospital services (inpatient and outpatient) based on hospital-specific reasonable costs attributable to serving Medicare beneficiaries. Later, the law was amended to limit payment to the lesser of a hospital's reasonable costs or its customary charges. In 1983, section 601 of the Social Security Amendments of 1983 (Pub. L. 98-21) completely revised the cost-based payment system for most hospital inpatient services by enacting section 1886(d) of the Social Security Act (the Act). This section provided for a prospective payment system (PPS) for acute hospital inpatient stays, effective with hospital cost reporting periods beginning on or after October 1, 1983.
Although payment for most inpatient services became subject to the PPS, Medicare hospital outpatient services continued to be paid based on hospital-specific costs, which provided little incentive for hospitals to furnish outpatient services efficiently. At the same time, advances in medical technology and changes in practice patterns were bringing about a shift in the site of medical care from the inpatient to the outpatient setting. During the 1980s, the Congress took steps to control the escalating costs of providing outpatient care. The Congress amended the statute to implement across-the-board reductions of 5.8 percent and 10 percent to the amounts otherwise payable by Medicare for hospital operating costs and capital costs, respectively, and enacted a number of different payment methods for specific types of hospital outpatient services. These methods included fee schedules for clinical diagnostic laboratory tests, orthotics, prosthetics, and durable medical equipment (DME); composite rate payment for dialysis for persons with end-stage renal disease (ESRD); and payments based on blends of hospital costs and the rates paid in other ambulatory settings such as separately certified ambulatory surgical centers (ASCs) or physician offices for certain surgery, radiology, and other diagnostic procedures. However, Medicare payment for services performed in the hospital outpatient setting remains largely cost-based.
In the Omnibus Budget Reconciliation Act of 1986 (OBRA 1986) (Pub. L. 99-509), the Congress paved the way for development of a PPS for hospital outpatient services. Section 9343(g) of OBRA 1986 mandated that fiscal intermediaries require hospitals to report claims for services under the HCFA Common Procedure Coding System (HCPCS). Section 9343(c) of OBRA 1986 extended the prohibition against unbundling of hospital services under section 1862(a)(14) of the Act to include outpatient services as well as inpatient services. The HCPCS coding enabled us to determine which specific procedures and services were being billed, while the extension of the prohibition against unbundling ensured that all nonphysician services provided to hospital outpatients would be billed only by the hospital, not by an outside supplier, and, therefore, would be reported on hospital bills and captured in the hospital outpatient data that could be used to develop an outpatient PPS.
A proposed rule to implement section 9343(c) was published in the
Federal Register
on August 5, 1988. However, those regulations were never published as a final rule, so we included them in the hospital outpatient PPS proposed rule published in the
Federal Register
on September 8, 1998 (63 FR 47552) and will implement them as part of this final rule.
Section 1866(g) of the Act, as added by section 9343(c) of OBRA 1986, and amended by section 4085(i)(17) of the Omnibus Budget Reconciliation Act of 1987 (OBRA 1987) (Pub. L. 100-203), authorizes the Department of Health and Human Services' Office of Inspector General to impose a civil money penalty (CMP), not to exceed $2,000, against any individual or entity who knowingly and willfully presents a bill in violation of an arrangement (as defined in section 1861(w)(1) of the Act).
In section 9343(f) of the OBRA 1986 and section 4151(b)(2) of the Omnibus Budget Reconciliation Act of 1990 (Pub. L. 101-508), the Congress required that we develop a proposal to replace the current hospital outpatient payment system with a PPS and submit a report to the Congress on the proposed system.
The Secretary submitted a report to the Congress on March 17, 1995, summarizing the research we conducted searching for a way to classify outpatient services for purposes of developing an outpatient PPS. The report cited ambulatory patient groups (APGs), developed by 3M-Health Information Systems (3M-HIS) under a cooperative grant with HCFA, as the most promising classification system for grouping outpatient services and recommended that APG-like groups be used in designing a hospital outpatient PPS.
The report also presented a number of options that could be used, once a PPS was in place, for addressing the issue of rapidly growing beneficiary coinsurance. As a separate issue, we recommended that the Congress amend the provisions of the law pertaining to the blended payment methods for ASC surgery, radiology, and other diagnostic services to correct an anomaly that resulted in a less than full recognition of the amount paid by the beneficiary in calculating program payment (referred to as the formula-driven overpayment).
Three sections of the Balanced Budget Act of 1997 (the BBA 1997) (Pub. L. 105-33), enacted on August 5, 1997, affect Medicare payment for hospital outpatient services. Section 4521 of the BBA 1997 eliminates the formula-driven overpayment for ambulatory surgical
center procedures, radiology services, and diagnostic procedures furnished on or after October 1, 1997. In November 1998, we issued cost report instructions (Provider Reimbursement Manual, Part II, Chapter 36, Transmittal 4) that implemented this provision for services furnished on or after October 1, 1997. Section 4522 of the BBA 1997 amends section 1861(v)(1)(S)(ii) of the Act by extending cost reductions in payment for hospital outpatient operating costs and hospital capital costs, 5.8 percent and 10 percent respectively, before January 1, 2000. Section 4523 of the BBA 1997 amends section 1833 of the Act by adding subsection (t), which provides for implementation of a PPS for outpatient services. (Under Section 4523 of the BBA 1997 the outpatient PPS does not apply to cancer hospitals before January 1, 2000.) Set forth below in section I.B is a detailed description of the changes made by the BBA 1997.
On November 29, 1999, the Balanced Budget Refinement Act of 1999 (the BBRA 1999), Pub. L. 106-113, was enacted. This Act made major changes that affect the proposed hospital outpatient PPS. The legislative changes are summarized in section I.E, below. More specific details on individual provisions that we are implementing in this final rule with comment period are included under the various sections of this preamble.
B.
Summary of Provisions in the Balanced Budget Act of 1997 (the BBA 1997)
1. Prospective Payment System (PPS)
Section 4523 of the BBA 1997 amended section 1833 of the Act by adding subsection (t), which provides for a PPS for hospital outpatient department services. (The following citations reflect the statute as enacted by the BBA 1997.) Section 1833(t)(1)(B) of the Act authorizes the Secretary to designate the hospital outpatient services that would be paid under the PPS. That section also requires that the hospital outpatient PPS include hospital inpatient services designated by the Secretary that are covered under Part B for beneficiaries who are entitled to Part A benefits but who have exhausted them or otherwise are not entitled to them. Section 1833(t)(1)(B)(iii) of the Act specifically excludes ambulance, physical and occupational therapy, and speech-language pathology services, for which payment is made under a fee schedule.
Section 1833(t)(2) of the Act sets forth certain requirements for the hospital outpatient PPS. The Secretary is required to develop a classification system for covered outpatient services that may consist of groups arranged so that the services within each group are comparable clinically and with respect to the use of resources.
Section 1833(t)(2)(C) of the Act specifies data requirements for establishing relative payment weights. The weights are to be based on the median hospital costs determined by 1996 claims data and data from the most recent available cost reports. Section 1833(t)(2)(D) of the Act requires that the portion of the Medicare payment and the beneficiary coinsurance that are attributable to labor and labor-related costs be adjusted for geographic wage differences in a budget neutral manner.
The Secretary is authorized under section 1833(t)(2)(E) of the Act to establish, in a budget neutral manner, other adjustments, such as outlier adjustments or adjustments for certain classes of hospitals, that are necessary to ensure equitable payments. Section 1833(t)(2)(F) of the Act requires the Secretary to develop a method for controlling unnecessary increases in the volume of covered outpatient services.
Section 1833(t)(3) of the Act specifies how beneficiary deductibles are to be treated in calculating the Medicare payment and beneficiary coinsurance amounts and requires that rules be established regarding determination of coinsurance amounts for covered services that were not furnished in 1996. The statute freezes beneficiary coinsurance at 20 percent of the national median charges for covered services (or group of covered services) furnished during 1996 and updated to 1999 using the Secretary's estimated charge growth from 1996 to 1999.
Section 1833(t)(3) of the Act also prescribes the formula for calculating the initial conversion factor used to determine Medicare payment amounts for 1999 and the method for updating the conversion factor in subsequent years.
Sections 1833(t)(4) and (t)(5) of the Act describe the method for determining the Medicare payment amount and the beneficiary coinsurance amount for services covered under the outpatient PPS. Section 1833(t)(5)(B) of the Act requires the Secretary to establish a procedure whereby hospitals may voluntarily elect to reduce beneficiary coinsurance for some or all covered services to an amount not less than 20 percent of the Medicare payment amount. Hospitals are further allowed to disseminate information on any such reductions of coinsurance amounts. Section 4451 of the BBA 1997 added section 1861(v)(1)(T) to the Act, which provides that any reduction in coinsurance must not be treated as a bad debt.
Section 1833(t)(6) authorizes periodic review and revision of the payment groups, relative payment weights, wage index, and conversion factor.
Section 1833(t)(7) of the Act describes how payment is to be made for ambulance services, which are specifically excluded from the outpatient PPS under section 1833(t)(1)(B) of the Act.
Section 1833(t)(8) of the Act provides that the Secretary may establish a separate conversion factor for services furnished by cancer hospitals that are excluded from hospital inpatient PPS.
Section 1833(t)(9) of the Act prohibits administrative or judicial review of the hospital outpatient PPS classification system, the groups, relative payment weights, wage adjustment factors, other adjustments, calculation of base amounts, periodic adjustments, and the establishment of a separate conversion factor for those cancer hospitals excluded from hospital inpatient PPS.
Section 4523(d) of the BBA 1997 made a conforming
amendment to section 1833(a)(2)(B) of the Act to provide for payment under the hospital outpatient PPS for some services described in section 1832(a)(2) that are currently paid on a cost basis and furnished by providers of services, such as comprehensive outpatient rehabilitation facilities (CORFs), home health agencies (HHAs), hospices, and community mental health centers (CMHCs). This amendment provides that partial hospitalization services furnished by CMHCs be paid under the PPS.
2. Elimination of Formula-Driven Overpayment
Before enactment of section 4521(b) of the BBA 1997, using the blended payment formulas for ASC procedures, radiology, and other diagnostic services, the ASC or physician fee schedule portion was calculated as if the beneficiary paid 20 percent of the ASC rate or physician fee schedule amount instead of the actual amount paid, which was 20 percent of the hospital's billed charges. Section 4521(b), which amended sections 1833(i)(3)(B)(i)(II) and 1833(n)(1)(B)(i) of the Act, corrects this anomaly by changing the blended calculations so that all amounts paid by the beneficiary are subtracted from the total payment in the calculation to determine the amount due from the program. Effective for services furnished on or after October 1, 1997, payment for surgery, radiology, and other diagnostic services calculated by blended payment methods is now calculated by
subtracting the full amount of coinsurance due from the beneficiary (based on 20 percent of the hospital's billed charges).
3. Extension of Cost Reductions
Section 1861(v)(1)(S)(ii) of the Act was amended by section 4522 of the BBA 1997 to require that the amounts otherwise payable for hospital outpatient operating costs and capital costs be reduced by 5.8 percent and 10 percent, respectively, through December 31, 1999.
C. The September 8, 1998 Proposed Rule
We published a proposed rule in the
Federal Register
on September 8, 1998 (63 FR 47552) setting forth the proposed PPS for hospital outpatient services. In that proposed rule, we explained that, due to Year 2000 (Y2K) systems concerns, implementation of the new payment system would be delayed until after January 1, 1999. (The statement in the rule that the statute requires implementation “effective January 1, 1999,” and other similar statements in other rules, were not intended to mean that the statute requires retroactive implementation of the hospital outpatient PPS. As noted elsewhere in this rule, the statute does not impose such a requirement.) As noted in that document, the scope of systems changes required to implement the hospital outpatient PPS is so enormous as to be impossible to accomplish concurrently with the critical work that we, our contractors, and our provider-partners had to perform to ensure that all of our respective systems were Y2K compliant. Section XI of the proposed rule (63 FR 47605) explains in greater detail the reasons for delaying implementation.
The proposed rule originally provided for a 60-day comment period. However, the comment period was extended four times, ultimately ending on July 30, 1999. (See 63 FR 63429, November 13, 1998; 64 FR 1784, January 12, 1999; 64 FR 12277, March 12, 1999; and 64 FR 36320; July 6, 1999.)
On June 30, 1999, we published a correction notice (64 FR 35258) to correct a number of technical and typographical errors contained in the September 8, 1998 proposed rule. The numerical values in the proposed rule reflected incorrect data and data programming. Among other corrections, the notice set forth revised numerical values for the current payment, total services (total units), relative weights, proposed payment rates, national unadjusted coinsurance, minimum unadjusted coinsurance, and service-mix index.
D. Overview of Public Comments
We received approximately 10,500 comments in response to our September 8, 1998 proposed rule. That count includes the numerous requests from hospital and other interested groups and organizations that we extend the public comment period to allow additional time for analysis of the impact of our proposals. As we explain above, we extended the comment period four times, to end finally on July 30, 1999.
In addition to receiving comments from a number of organizations representing the full spectrum of the hospital industry, we received comments from beneficiaries and their families, physicians, health care workers, individual hospitals, professional associations and societies, legal and nonlegal representatives and spokespersons for beneficiaries and hospitals, members of the Congress, and other interested citizens. The majority of comments addressed our proposals regarding payment for: Corneal tissue; payment for high-cost technologies, both existing and future; payment for blood and blood products; and payment for high cost drugs, including chemotherapy agents. We also received numerous comments addressing: Our approach to ratesetting using the ambulatory payment classification (APC) system; our method of calculating the payment conversion factor; and the potentially negative impact of the proposed hospital outpatient PPS on hospital revenues. In addition, we received many comments concerning the proposed regulations for provider-based entities.
We carefully reviewed and considered all comments received timely. The many modifications that we made to our proposed regulations in response to commenters' suggestions and recommendations are reflected in the provisions of this final rule. Comments and our responses are addressed by topic in the sections that follow.
E. Summary of Relevant Provisions in the Balanced Budget Refinement Act of 1999 (the BBRA 1999)
As noted above, subsequent to publication of the proposed rule, the BBRA 1999 was enacted on November 29, 1999. The BBRA 1999 made major changes that affect the proposed hospital outpatient PPS. Because these changes are effective with the implementation of the PPS, we have had to make some revisions from the September 8, 1998 proposed rule. The provisions of the BBRA 1999 that we are implementing in this final rule with comment period follow.
1. Outlier Adjustment
Section 201(a) of the BBRA 1999 amends section 1833(t) by redesignating paragraphs (5) through (9) as paragraphs (7) through (11) and adding a new paragraph (5). New section 1833(t)(5) of the Act provides that the Secretary will make payment adjustments for covered services whose costs exceed a given threshold (that is, an outlier payment). This section describes how the additional payments are to be calculated and caps the projected outlier payments at no more than 2.5 percent of the total projected payments (sum of both Medicare and beneficiary payments to the hospital) made under hospital outpatient PPS for years before 2004 and 3.0 percent of the total projected payments for 2004 and subsequent years.
2. Transitional Pass-Through for Additional Costs of Innovative Medical Devices, Drugs, and Biologicals
Section 201(b) of the BBRA 1999 adds new section 1833(t)(6) to the Act, establishing transitional pass-through payments for certain medical devices, drugs, and biologicals. This provision does the following: Specifies the types of items for which additional payments must be made; describes the amount of the additional payment; limits these payments to at least 2 years but not more than 3 years; and caps the projected payment adjustments annually at 2.5 percent of the total projected payments for hospital outpatient services each year before 2004 and no more than 2.0 percent in subsequent years. Under this provision, the Secretary has the authority to reduce pro rata the amount of the additional payments if, before the beginning of a year, she estimates that these payments would otherwise exceed the caps.
3. Budget Neutrality Applied to New Adjustments
Section 201(c) of the BBRA 1999 amends section 1833(t)(2)(E) of the Act to require that the establishment of outlier and transitional pass-through payment adjustments is to be made in a budget neutral manner.
4. Limitation on Judicial Review
Section 201(d) of the BBRA 1999 amends redesignated section 1833(t)(11) of the Act by extending the prohibition of administrative or judicial review to include the factors for determining outlier payments (that is, the fixed multiple, or a fixed dollar cutoff amount, the marginal cost of care, or applicable total payment percentage), and the determination of additional payments for certain medical devices,
drugs, and biologicals, the insignificant cost determination for these items, the duration of the additional payment or portion of the PPS payment amount associated with particular devices, drugs, or biologicals, and any pro rata reduction.
5. Inclusion in the Hospital Outpatient PPS of Certain Implantable Items
Section 201(e) of the BBRA 1999 amends section 1833(t)(1)(B) of the Act to include as covered outpatient services implantable prosthetics and DME and diagnostic x-ray, laboratory, and other tests associated with those implantable items.
6. Payment Weights Based on Mean Hospital Costs
Section 201(f) of the BBRA 1999 amends section 1833(t)(2)(C) of the Act, which specifies data requirements for establishing relative payment weights, to allow the Secretary the discretion to base the weights on either the median or mean hospital costs determined by data from the most recent available cost reports.
7. Limitation on Variation of Costs of Services Classified Within a Group
Section 201(g) of the BBRA 1999 amends section 1833(t)(2) of the Act to limit the variation of costs of services within each payment classification group by providing that the highest median (or mean cost, if elected by the Secretary) for an item or service within the group cannot be more than 2 times greater than the lowest median (or mean) cost for an item or service within the group. The provision allows the Secretary to make exceptions in unusual cases, such as for low volume items and services.
8. Annual Review of the Hospital Outpatient PPS Components
Section 201(h) of the BBRA 1999 amends redesignated section 1833(t)(8) of the Act to require at least annual review of the groups, relative payment weights, and the wage and other adjustments made by the Secretary to take into account changes in medical practice, the addition of new services, new cost data, and other relevant information and factors. That section of the Act is further amended to require the Secretary to consult with an expert outside advisory panel composed of an appropriate selection of provider representatives who will review the clinical integrity of the groups and weights and advise the Secretary accordingly. The panel may use data other than those collected or developed by the Department of HHS for the review and advisory purposes.
9. Coinsurance Not Affected by Pass-Throughs
Section 201(i) of the BBRA 1999 amends redesignated section 1833(t)(7) of the Act to provide that the beneficiary coinsurance amount will be calculated as if the outlier and transitional pass-throughs had not occurred; that is, there will be no coinsurance collected from beneficiaries for the additional payments made to hospitals by Medicare for these adjustments.
10. Extension of Cost Reductions
Section 201(k) of the BBRA 1999 amends section 1861(v)(1)(S)(ii) of the Act to extend until the first date that the hospital outpatient PPS is implemented, the 5.8 and 10 percent reductions for hospital operating and capital costs, respectively.
11. Clarification of Congressional Intent Regarding Base Amounts Used in Determining the Hospital Outpatient PPS
Section 201(l) of the BBRA 1999 provides that, “With respect to determining the amount of copayments described in paragraph (3)(A)(ii) of section 1833(t) of the Social Security Act, as added by section 4523(a) of the BBA, Congress finds that such amount should be determined without regard to such section, in a budget neutral manner with respect to aggregate payments to hospitals, and that the Secretary of Health and Human Services has the authority to determine such amount without regard to such section.” Pursuant to this provision, we are calculating the aggregate PPS payment to hospitals in a budget neutral manner.
12. Transitional Corridors for Application of Outpatient PPS
Section 202 of the BBRA 1999 amends section 1833(t) of the Act by redesignating paragraphs (7) through (11) as paragraphs (8) through (12), and adding a new paragraph (7), which provides for a transitional adjustment to limit payment reductions under the hospital outpatient PPS. More specifically, for the years 2000 through 2003, a provider, including a CMHC, will receive an adjustment if its payment-to-cost ratio for outpatient services furnished during the year is less than a set percentage of its payment-to-cost ratio for those services in its cost reporting period ending in 1996 (the base year). Two categories of hospitals, rural hospitals with 100 or fewer beds and cancer hospitals, will be held harmless under this provision. Small rural hospitals, for services furnished before January 1, 2004, will be maintained at the same payment-to-cost ratio as their base year cost report if their PPS payment-to-cost ratio is less. The hold-harmless provision applies permanently to cancer centers. Section 202 also requires the Secretary to make interim payments to affected hospitals subject to retrospective adjustments and requires that the provisions of this section do not affect beneficiary coinsurance. Finally, this provision is not subject to budget neutrality.
13. Limitation on Coinsurance for a Procedure
Section 204 of the BBRA 1999 amends redesignated section 1833(t)(8) of the Act to provide that the coinsurance amount for a procedure performed in a year cannot exceed the hospital inpatient deductible for that year.
14. Reclassification of Certain Hospitals
Section 401 of the BBRA 1999 adds section 1886(d)(8)(E) to the Act to permit reclassification of certain urban hospitals as rural hospitals. Section 401 adds section 1833(t)(13) to the Act to provide that a hospital being treated as a rural hospital under section 1886(d)(8)(E) also be treated as a rural hospital under the hospital outpatient PPS.
II. Prohibition Against Unbundling of Hospital Outpatient Services
A. Background
Sections 9343(c)(1) and (c)(2) of OBRA 1986 amended sections 1862(a)(14) and 1866(a)(1)(H) of the Act, respectively. As revised, section 1862(a)(14) of the Act prohibits payment for nonphysician services furnished to hospital patients (inpatients and outpatients), unless the services are furnished by the hospital, either directly or under an arrangement (as defined in section 1861(w)(1) of the Act). As revised, section 1866(a)(1)(H) of the Act requires each Medicare-participating hospital to agree to furnish directly all covered nonphysician services required by its patients (inpatients and outpatients) or to have the services furnished under an arrangement (as defined in section 1861(w)(1) of the Act). Section 9338(a)(3) of OBRA 1986 affected implementation of the bundling mandate by amending section 1861(s)(2)(K) of the Act to permit services of physician assistants to be covered and billed separately. Sections 4511(a)(2)(C) and (D) of the BBA 1997 further revised sections 1862(a)(14) and 1866(a)(1)(H) of the Act, respectively, to exclude services of nurse practitioners
and clinical nurse specialists, described in section 1861(s)(2)(K)(ii) of the Act, from the bundling requirement.
B. Office of Inspector General (OIG) Civil Money Penalty Authority and Civil Money Penalties for Unbundling Hospital Outpatient Services
In order to deter the unbundling of nonphysician hospital services, section 9343(c)(3) of OBRA 1986 added section 1866(g) to the Act to provide for the imposition of civil money penalties (CMPs), not to exceed $2,000, against any person who knowingly and willfully presents, or causes to be presented, a bill or request for payment for a hospital outpatient service under Part B of Medicare that violates the requirement for billing under arrangements specified in section 1866(a)(1)(H) of the Act. In addition, section 1866(g) includes authorization to impose a CMP, in the same manner as other CMPs are imposed under section 1128A of the Act when arrangements should have been made but were not. Section 4085(i)(17) of OBRA 1987 amended section 1866(g) of the Act by deleting all references to hospital outpatient services under Part B of Medicare. The result of this amendment is that the CMP is now applicable for services furnished to hospital patients, whether paid for under Medicare Part A or B.
In order to implement section 1866(g) of the Act, we proposed in our August 5, 1988 proposed rule that the OIG would impose a CMP against any person who knowingly and willfully presents, or causes to be presented, a bill or request for payment for a hospital outpatient service under Part B of Medicare that violates the billing arrangement under section 1866(a)(1)(H) of the Act or the requirement for an arrangement. The amount of the CMP is to be limited to $2,000 for each improper bill or request, even if the bill or request included more than one item or service.
C. Summary of Final Regulations on Bundling of Hospital Outpatient Services
In our September 8, 1998 proposed rule, we proposed to make final most of the provisions of the August 5, 1988 proposed rule but with a number of revisions that we describe in detail in the proposed rule (63 FR 47558 through 47559). We are adopting as final regulations what we proposed in the September 8, 1998 rule with the following additional changes:
• We are adding a new paragraph (b)(7) to § 410.42 (Limitations on coverage of certain services furnished to hospital outpatients) to provide an exception to the hospital bundling requirements for services hospitals furnish to SNF residents as defined in § 411.15(p). (Section 410.42 has been redesignated from § 410.39 in the proposed rule.)
• We are making a minor change to newly redesignated paragraph (m)(2) (this language was formerly included in paragraph (m)(1)) in § 411.15 (Particular services excluded from coverage) to make it clearer that the exclusion discussed in this section is referring to excluding certain services from coverage.
• Except for minor wording changes in introductory paragraph (b) of § 1003.102 (Basis for civil money penalties and assessments), that section remains as it appeared in the August 5, 1988 proposed rule. Paragraph (b)(15) is redesignated from proposed paragraph (b)(4) in the August 5, 1988 proposed rule and (b)(14) in the September 8, 1998 proposed rule. Paragraphs (b)(12) through (b)(14) of § 1003.102 are reserved.
• We are adding a new paragraph (k) to § 1003.103 (Amount of penalty) to indicate that the OIG may impose a penalty of not more than $2,000 for each bill or request for items and services furnished to hospital patients in violation of the bundling requirements.
• We are also amending § 1003.105 (Exclusion from participation in Medicare, Medicaid and other Federal health care programs) by revising paragraph (a)(1)(i) to reflect that the basis for imposition of a CMP is also a basis for exclusion from participation in Medicare, Medicaid and other Federal health care programs.
D. Comments and Responses
Comment:
One association requested that we clarify whether lab tests are subject to the bundling requirement or whether those services are included in the definition of diagnostic tests that are not required to be bundled. If lab tests are bundled, the association asked that we seek a legislative change to permit a provider, other than the lab that performs the test, to bill for the test.
Response:
Laboratory tests, like all other services furnished to hospital patients, must be provided directly or under arrangements by the hospital and only the hospital may bill the program. Section 1833(h)(5)(A)(iii) of the Act provides an exception to the requirement that payment for a clinical diagnostic lab may be made only to the person or entity that performed or supervised the performance of the test. This section provides that in the case of a clinical diagnostic laboratory test provided under arrangement made by a hospital or CAH, payment is made to the hospital.
All diagnostic tests that are furnished by a hospital, directly or under arrangements, to a registered hospital outpatient during an encounter at a hospital are subject to the bundling requirements. The hospital is not responsible for billing for the diagnostic test if a hospital patient leaves the hospital and goes elsewhere to obtain the diagnostic test.
Comment:
The same association asked us to clarify that services billed to skilled nursing facilities (SNFs) under the consolidated billing requirement would be exempt from the bundling requirement for hospital outpatient services.
Response:
We agree that in situations where a beneficiary receives outpatient services from a Medicare participating hospital or CAH while temporarily absent from the SNF, the beneficiary continues to be considered a SNF resident specifically with regard to the comprehensive care plan required under § 483.20(b). Such services are, therefore, subject to the SNF consolidated billing provision and should be exempt from the hospital outpatient bundling requirements. The final regulations at § 410.42(b)(7) reflect this exception.
We note that the SNF consolidated billing requirements, under § 411.15(p)(3)(iii), do not apply to a limited number of exceptionally intensive hospital outpatient services that lie well beyond the scope of care that SNFs would ordinarily furnish, and thus beyond the ordinary scope of SNF care plans. The hospital outpatient services that are currently included in this policy are: Cardiac catheterization; computerized axial tomography (CAT) scans; MRIs; ambulatory surgery involving the use of an operating room; emergency room services; radiation therapy; angiography; and lymphatic and venous procedures. When a hospital or CAH provides these services to a beneficiary, the beneficiary's status as a SNF resident ends, but only with respect to these services. The beneficiary is now considered to be a hospital outpatient and the services are subject to hospital outpatient bundling requirements. In November 1998, we issued Program Memorandum transmittal number A-98-37, which provides additional clarification on this exclusion as well as a list of specific HCPCS codes that identify the services that are excluded from SNF consolidated billing but subject to hospital outpatient bundling.
Comment:
One commenter understood that the proposed rule
would permit payment for all diagnostic tests that are furnished by a hospital or other entity if the patient leaves the hospital and obtains the service elsewhere; however, the commenter requested clarification as to the treatment of “outsourced” hospital departments. The commenter stated that hospitals are increasingly outsourcing departments to providers that can furnish services efficiently. Often these providers do not operate as “under arrangements” providers to the hospital, but as free-standing providers offering outpatient services on hospital grounds. The commenter specifically asked whether a free-standing entity providing outpatient services on hospital grounds, but operated independently of the hospital is able to bill separately for services furnished or is the entity considered to be part of the hospital and required to furnish services “under arrangement.”
Response:
A free-standing entity, that is, one that is not provider-based, may bill for services furnished to beneficiaries who do not meet the definition of a hospital outpatient at the time the service is furnished. Our bundling requirements apply to services furnished to a “hospital outpatient,” as defined in § 410.2, during an “encounter,” also defined in § 410.2.
Comment:
One commenter indicated that while the proposed revision to § 1003.102(b) accurately reflected the statutory directive that the basis for imposing a CMP is a “bill or request for payment,” the proposed amendment to § 1003.103(a) regarding the appropriate penalty amount to be imposed for bundling violations was in error. The commenter indicated that the OIG lacks the authority to impose a CMP in the amount of $10,000 for these violations, and that such a penalty should be not more than $2,000 for each violation.
Response:
The commenter is correct. While section 231(c) of the Health Insurance Portability and Accountability Act of 1996, Pub. L. 104-191, increased the CMP maximum amount from $2,000 to $10,000, the statute sets forth “items or services” as the basis upon which a higher CMP amount may be assessed. However, with regard to bundling violations, the Secretary may impose a CMP only on the basis of a “bill or request for payment” rather than “for each item and service” as stated in the proposed revision to § 1003.103. We are correcting this error by adding a new § 1003.103(k) to indicate that the OIG may impose a penalty of not more than $2,000 for each bill or request for items and services furnished to hospital patients in violation of the bundling requirements.
III. Hospital Outpatient Prospective Payment System (PPS)
In this section, we designate the services for which Medicare will make payment under the hospital outpatient PPS, the payment rates set for those services, and the method by which we determined the outpatient PPS payment and coinsurance amounts.
We explain the structure of the hospital outpatient PPS, respond to comments that we received about the proposed PPS, and describe modifications that we made to the proposed PPS in response to comments, such as provisions we are making to expedite appropriate payment for new technologies and provisions to pay for blood and blood products.
In this section, we also discuss how we will implement requirements enacted by the BBRA 1999, including transitional payment corridors and other payment adjustments such as outliers and transitional pass-throughs.
A. Hospitals Included In or Excluded From the Outpatient PPS
This PPS applies to covered hospital outpatient services furnished by all hospitals participating in the Medicare program, except as noted below. Partial hospitalization services in community mental health centers (CMHCs) are also paid under this PPS. Exclusions from outpatient PPS are different and more limited than exclusions from inpatient PPS. Thus, hospitals or distinct parts of hospitals that are excluded from the inpatient PPS are included in the outpatient PPS, to the extent that the hospital or distinct part furnishes outpatient services. For example, we will make payment under the outpatient PPS for outpatient psychiatric services. The outpatient services provided by hospitals of the Indian Health Service (IHS) will continue to be paid under separately established rates which are published annually in the
Federal Register
. We intend to develop a plan that will help these facilities transition to the PPS and will consult with the IHS to develop this plan.
The following hospitals are excluded from the outpatient PPS:
• Certain hospitals in Maryland qualify under section 1814(b)(3) of the Act for payment under the State's payment system. The excluded services are limited to those paid under the State's payment system as described in section 1814(b)(3) of the Act. Any other outpatient services furnished by the hospital are paid under the outpatient PPS.
• Critical access hospitals that are paid under a reasonable cost based system, as required under section 1834(g) of the Act.
Comment:
National and State associations representing children's hospitals and a number of individual children's hospitals located across the country strongly recommended that their hospitals be excluded from the hospital outpatient PPS just as they have been excluded from the hospital inpatient PPS. These commenters argued that the exclusion should apply to outpatient services furnished by children's hospitals because these hospitals treat a unique patient group whose health needs are different from those of adult beneficiaries entitled to Medicare benefits. The commenters further argued that services to Medicare patients are, on average, only 1 percent of the total inpatient and outpatient services that children's hospitals furnish and that these services are largely ESRD services that are already excluded from the hospital outpatient PPS. The commenters were concerned that the resources required to implement and comply with the new system would be disproportionately high relative to the small number of patients who would be affected by the new system. In addition, the impact analysis that accompanied the proposed rule estimated that children's hospitals would lose more than 20 percent of their Medicare revenues under the new system. Commenters expressed great concern about this loss of revenue.
Response:
Our most recent analysis of the impact on hospitals of the PPS shows a negative effect for children's hospitals of 11.9 percent, which is significantly less than what we estimated in the proposed rule. However, the transitional corridor payments provided by the BBRA 1999 will protect these hospitals from even this level of loss through 2004. The estimated loss for CY 2000-2001 for children's hospitals is only 3.2 percent. (See Table 2 in section IX of this preamble.) As we discuss in section III.H.2 below, we will conduct extensive analyses during the first years of implementation of the PPS to determine whether we should propose adjustments for certain types of hospitals, including children's hospitals, when the transitional corridor provision expires. In the meantime, we are not excluding any special class of hospital from the PPS.
B. Scope of Facility Services
Section 1833(t)(1)(B)(i) of the Act gives us the authority to designate the services to be covered under the hospital outpatient PPS. In this section of the final rule, we designate the types
of services included or excluded under the hospital outpatient PPS.
1. Services Excluded From the Scope of Services Paid Under the Hospital Outpatient PPS
a. Background
In developing a hospital outpatient PPS, we want to ensure that all services furnished in a hospital outpatient setting will be paid on a prospective basis. We have already been paying, in part, for some hospital outpatient services such as clinical diagnostic laboratory services, orthotics, and end-stage renal disease (ESRD) dialysis services based on fee schedules or other prospectively determined rates that also apply across other sites of ambulatory care. Rather than duplicate existing payment systems that are effectively achieving consistency of payments across different service delivery sites, we proposed to exclude from the outpatient PPS those services furnished in a hospital outpatient setting that were already subject to an existing fee schedule or other prospectively determined payment rate. The similar payments across various settings create a more level playing field in which Medicare makes virtually the same payment for the same service, without regard to where the service is furnished.
We therefore proposed to exclude from the scope of services paid under the hospital outpatient PPS the following:
• Services already paid under fee schedules or other payment systems including, but not limited to: screening mammographies, services for patients with ESRD that are paid for under the ESRD composite rate; the professional services of physicians and non-physician practitioners paid under the Medicare physician fee schedule; laboratory services paid under the clinical diagnostic laboratory fee schedule; and DME, orthotics, prosthetics, and prosthetics devices, prosthetic implants, and supplies (DMEPOS) paid under the DMEPOS fee schedule when the hospital is acting as a supplier of these items. An item such as crutches or a walker that is given to the patient to take home, but that may also be used while the patient is at the hospital, would be billed to the DME regional carrier rather than paid for under the hospital outpatient PPS.
• Hospital outpatient services furnished to SNF inpatients as part of his or her resident assessment or comprehensive care plan (and thus included under the SNF PPS) that are furnished by the hospital “under arrangements” but billable only by the SNF, regardless of whether or not the patient is in a Part A SNF stay.
• Services and procedures that require inpatient care.
The statute excludes from the definition of “covered OPD services” ambulance services, physical and occupational therapy, and speech-language pathology services, specified in section 1833(t)(1)(B)(iii) of the Act (redesignated as section 1833(t)(1)(B)(iv) by section 201(e) of the BBRA 1999). These services are to be paid under fee schedules in all settings.
b. Comments and Responses
Comment:
One commenter urged that we exclude services furnished to ESRD patients from the scope of the hospital outpatient PPS.
Response:
Services furnished to ESRD patients include dialysis, Epoietin (EPO), drugs, and supplies provided outside the composite rate, surgery specific to access grafts, and many other medical services related to renal disease or to other coexisting conditions. We will continue to base payment for dialysis services on the composite rate, and we will continue to pay for EPO based on the current rate established for that service. The drugs and supplies that are used within a dialysis session, but for which payment is not included in the composite rate, are paid outside that rate. We have to conduct further analyses in order to develop appropriate APC groups upon which to base payment. In the meantime, we will continue to pay on a reasonable cost basis for dialysis related drugs and supplies that are paid outside the composite rate.
Comment:
A hospital industry association took exception to the requirement that hospitals obtain a separate supplier number, post a bond, and bill separately to the DME regional carrier for DME supplies such as crutches. They believe that this is an unnecessary requirement that results in additional costs for small rural hospitals. The commenter recommended that we include within the PPS rate supplies such as crutches that are directly related to the provison of the hospital outpatient services or that we permit hospitals to bill under the DME fee schedule without having to obtain a DME supplier number or post a bond.
Response:
Section 1834(j)(1)(A) of the Act provides that no payment may be made for items furnished by a supplier of medical equipment and supplies unless the supplier obtains a supplier number. Section 1834(a)(1)(C) of the Act provides that payment for DME can be made only under the DME fee schedule. Therefore, to receive payment for DME under Medicare, a hospital must obtain a supplier number and must meet the other requirements set by applicable Medicare rules and regulations.
Comment:
Several major hospital associations and a number of other commenters opposed our proposal to exclude from payment certain procedures that we designate as “inpatient only.” Other commenters, including a physician professional society, agree that many of the procedures that we designated in the proposed rule as “inpatient only” are currently performed appropriately and safely only in the inpatient setting. However, these commenters believe that our explicit exclusion of individual procedures, besides being unnecessary, could have an adverse effect on advances in surgical care. Some commenters alleged that we provided no concrete support for designating procedures as “inpatient only.” A number of commenters argued that medicine is not practiced uniformly across the nation and that some services listed among the exclusions are currently being performed on an outpatient basis in various parts of the country with positive outcomes.
An industry association stated that we failed to consider surgical judgment and patient choice in determining the appropriate treatment setting for certain services that we proposed to exclude from coverage. Other commenters believe that the appropriate site for performing a medical service is best determined by physicians and their patients. One professional society stated that case law including medical malpractice case law is sufficient to ensure that medical services are delivered in the appropriate treatment setting and in conformance with prevailing medical standards.
Response:
We recognize and acknowledge that our assigning “inpatient only” status to certain services and procedures raises numerous questions and concerns, and that some individual determinations can be reasonably debated. However, section 1833(t)(1)(B) of the Act explicitly authorizes the Secretary to designate which hospital outpatient services are to be “covered OPD services” subject to payment under the hospital outpatient PPS. Therefore, we have had to select from the universe of possible services those that we determine are reasonable, necessary, and appropriate for Medicare payment under the hospital outpatient PPS. We note that our designation of a service as “inpatient only” does not necessarily preclude the service from being furnished in a hospital outpatient
setting, but means only that Medicare will not make payment for the service were it to be furnished to a Medicare beneficiary in that setting. This unfortunately leaves the beneficiary liable for payment if the procedure is in fact performed in the outpatient setting. We hope that hospitals will advise beneficiaries of the consequences if procedures on the inpatient list are provided as outpatient services (that is, denial of Medicare payment with concomitant beneficiary liability). In section III.C.5 of this preamble, we discuss in greater detail our rationale for designating specific procedures as “inpatient only.” In response to comments, we have removed the “inpatient only” status from a number of services, which will allow them to be paid under the hospital outpatient PPS. We emphasize our intention to review annually, in consultation with hospital and professional societies and associations and the expert outside advisory panel mandated by the BBRA 1999, those procedures classified as “inpatient only” to ensure that the designation remains consistent with current standards of practice.
Comment:
One industry association contends that the statutory and regulatory authorities that we cite in the proposed rule (section 1862(a)(1)(A) of the Act and 42 CFR 411.15(k)(1), respectively) do not support the proposed medical services exclusions. The commenter argues that those provisions are the basis for prohibiting coverage for services that are not reasonable and necessary for the diagnosis or treatment of an illness or injury or to improve the functioning of a malformed body member. The commenter states that these provisions are not the basis upon which we identified services for the “inpatient only” list. The commenter further states that use of these provisions as a basis for denying coverage of the services would be confusing to beneficiaries.
Response:
The commenter is correct that the proper citations are not section 1862(a)(1) of the Act and 42 CFR 411.15(k)(1). In fact, the basis for our designating certain procedures as “inpatient only” is dependent on medical judgment regarding the proper site of service, and the proper citation for such designation is section 1833(t)(1)(B) of the Act. In some instances, the identification of services to be included or excluded from this PPS was perfectly clear. For example, emergency departments (EDs) are outpatient departments of hospitals. Thus emergency services rendered in EDs qualify as outpatient services. On the other hand, coronary artery bypass graft surgery (CABG) requires many hours in surgery, part of the time with the patient's life being sustained by artificial means; a period of hours, if not days, in the surgical intensive care unit (ICU); and further care in an inpatient unit with frequent nursing attention. It clearly cannot be an outpatient procedure, and it would not be reasonable to consider it for inclusion in this PPS. There are many procedures which require similar intensity of care, including periods in specialty ICUs and several days of intense nursing attention.
Some procedures formerly performed only in the inpatient setting, however, have moved to the outpatient site of service. This movement has taken place due to new, less-invasive surgical techniques, such as laparoscopy, or new anesthesia agents that clear from the body more rapidly, allowing some patients to have general anesthesia in the morning and return home that afternoon. Thus we have had to decide which procedures may reasonably be performed in the outpatient setting, and which cannot. We have been guided in this decision by our medical advisors' clinical judgment regarding what is reasonable in various settings, comments we received in response to the proposed rule, and bill data which shows movement from one site to another. In section III.C.5, we discuss the criteria we considered in defining “inpatient only” procedures.
Comment:
One hospital asked how we would pay a hospital that routinely performs on an outpatient basis a procedure that we proposed to designate as “inpatient only.” The commenter recommended that a specific billing mechanism be used to guarantee payment in these situations.
Response:
Services designated as “inpatient only” will be excluded from Medicare payment under the hospital outpatient PPS. If the service is performed on an outpatient basis and a claim is submitted, the claim will be denied, and the beneficiary may be billed for the service. We would consider this a very poor policy on the hospital's part, and would hope that hospitals decide to abide by the constraints of the inpatient list.
Comment:
One commenter noted that hospital outpatient departments have never been limited to a list of approved procedures as are Medicare participating ASCs. The commenter stated that the “inpatient only” policy would exclude payment for a significant number of procedures that have traditionally been performed in the hospital outpatient setting. The commenter stated that some of the excluded procedures incorporate an observation stay in a recovery care center. The commenter contended that many of the excluded procedures could be safely performed in the outpatient setting particularly if a 24 to 72 hour recovery care center is part of the outpatient surgical care provided.
Response:
Routinely billing an observation stay for patients recovering from outpatient surgery is not allowed under current Medicare rules nor will it be allowed under the hospital outpatient PPS. As we state in section III.C.5 of this preamble, one of the primary factors we considered as an indicator for the “inpatient only” designation is the need for at least 24 hours of postoperative care.
Comment:
One commenter asked what option a hospital has if a beneficiary's secondary insurer requires that a procedure included on the Medicare inpatient only list be performed on an outpatient basis.
Response:
Upon implementation, the provisions of this final rule will govern payment for Medicare covered outpatient services furnished by hospitals to Medicare beneficiaries. Medicare payment policy and rules are not binding on employer-provided retiree coverage that may supplement Medicare coverage. Medigap insurers, however, must follow Medicare's coverage determinations.
c. Payment for Certain Implantable Items Under the BBRA 1999
In the course of identifying items and services whose costs we proposed to designate for payment under the hospital outpatient PPS, we gave considerable thought to including implantable items and services because these items and services are such an integral part of the procedure by which they are inserted or implanted. However, a number of the more common implants such as aqueous shunts, hallux valgus implants, infusion pumps, and neurostimulators, are classified as implantable prosthetics or DME. The statutory language governing payment for DMEPOS provides that, notwithstanding any other provision of the Medicare statute, DMEPOS must be paid for using the DMEPOS fee schedule. Therefore, under the proposed rule, the scope of services paid under the hospital outpatient PPS did not include implantable prosthetics and DME paid under the DMEPOS fee schedule. However, we did propose to package payment for implanted items such as stents, vascular catheters, and venous ports within the APC payment rate for the procedure related to the insertion of these items because we
define these items as supplies rather than as prosthetic implants or implantable DME.
Section 201(e) of the BBRA 1999 amends section 1833(t)(1)(B) of the Act to provide that “covered OPD services” include implantable items described in paragraph (3), (6), or (8) of section 1861(s) of the Act. The conference report accompanying the BBRA 1999, H. R. Rep. No. 436 (Part I), 106th Cong., 1st Sess. (1999), expresses the belief of the conferees that the current DMEPOS fee schedule is not appropriate for certain implantable medical items such as pacemakers, defibrillators, cardiac sensors, venous grafts, drug pumps, stents, neurostimulators, and orthopedic implants as well as items that come into contact with internal human tissue during invasive medical procedures, but are not permanently implanted. In the conference report agreement, the conferees state their intention that payment for these items be made through the outpatient PPS, regardless of how these products might be classified on current HCFA fee schedules. The implantable items affected by this BBRA 1999 requirement include prosthetic implants (other than dental) that replace all or part of an internal body organ (including colostomy bags and supplies directly related to colostomy care and including replacement of these devices); implantable DME; and implantable items used in performing diagnostic x-rays, diagnostic laboratory tests, and other diagnostic tests.
Comment:
A number of commenters disagreed with our proposal to pay under the DMEPOS fee schedule for implantable items and devices that require surgical insertion. We received comments on specific implantable items, including Vitrasert (a drug delivery system that is implanted in the eye); cochlear devices, which allow the profoundly deaf to hear sound and in some cases recognize speech; nerve stimulators that treat intractable epilepsy and other diseases; new technology intraocular lenses implanted following cataract surgery; and access devices for dialysis treatment. Commenters were also concerned that the costs of some implantable devices not paid under the DMEPOS fee schedule, which we packaged in our proposed rule, were not properly recognized in the APC payment.
Response:
As we explain above, the amendments made to the statute by section 201(e) of the BBRA 1999 provide for payment to be made under the hospital outpatient PPS for implantable items that are part of diagnostic x-rays, diagnostic laboratory tests, and other diagnostic tests; implantable durable medical equipment; and implantable prosthetic devices (other than dental). This BBRA 1999 provision requires that an implantable item be classified to the group that includes the service to which the item relates. Thus, under this final rule with comment period, we are including within the scope of the hospital outpatient PPS items such as aqueous shunts that would, absent the BBRA 1999 provision, have been paid under the DMEPOS fee schedule. Because implantable items are now packaged into the APC payment rate for the service or procedure with which they are associated, certain items may be candidates for the transitional pass-through payment, which is discussed in detail in section III.D of this preamble. The APC rates may not in every case perfectly recognize the cost of implantable items. We will continue to review the impact of packaging implantables in future updates.
d. Summary of Final Action
We are modifying proposed § 419.22 to remove prosthetic implants from the list of services excluded from payment under the hospital outpatient PPS. We are adding subparagraphs (9), (10), and (11) to proposed § 419.2(b), to include the following in the list of items and services whose costs are included in hospital outpatient PPS payment rates: prosthetic implants (other than dental) that replace all or part of an internal body organ (including colostomy bags and supplies directly related to colostomy care), and including replacement of these devices; implantable DME; and implantable items used in performing diagnostic x-rays, diagnostic laboratory tests, and other diagnostic tests.
2. Services Included Within the Scope of the Hospital Outpatient PPS
We proposed to include three categories of services within the scope of the outpatient PPS, as follows:
a. Services for Patients Who Have Exhausted Their Part A Benefits
Section 1833(t)(1)(B)(ii) of the Act provides for Medicare payment under the hospital outpatient PPS for certain services designated by the Secretary that are furnished to inpatients who have exhausted their Part A benefits or who are otherwise not in a covered Part A stay. Examples of services covered under this provision include diagnostic x-rays and certain other diagnostic services and radiation therapy covered under section 1832 of the Act.
b. Partial Hospitalization Services
Section 1833(a)(2)(B) of the Act provides that partial hospitalization services furnished in CMHCs be paid under the hospital outpatient PPS. Partial hospitalization is a distinct and organized intensive psychiatric outpatient day treatment program, designed to provide patients who have profound and disabling mental health conditions with an individualized, coordinated, comprehensive, and multidisciplinary treatment program.
c. Services Designated by the Secretary
We proposed to designate the following services to be paid under the hospital outpatient PPS:
• All hospital outpatient services, except those that are identified as excluded, above, in section III.B.1 of this final rule. The types of services subject to payment under the hospital outpatient PPS include the following: surgical procedures; radiology, including radiation therapy; clinic visits; emergency department visits; diagnostic services and other diagnostic tests; partial hospitalization for the mentally ill; surgical pathology; and cancer chemotherapy.
• Specific hospital outpatient services furnished to a beneficiary who is admitted to a Medicare-participating SNF but who is not considered to be a SNF resident, for purposes of SNF consolidated billing, with respect to those services that are beyond the scope of SNF comprehensive care plans. The specific hospital outpatient services that are excluded from SNF consolidated billing are cardiac catheterization, computerized axial tomography (CAT) scans, MRIs, ambulatory surgery involving the use of an operating room, emergency room services, radiation therapy, angiography, and lymphatic and venous procedures.
• Supplies such as surgical dressings used during surgery or other treatments in the hospital outpatient setting that are also paid under the DMEPOS fee schedule. Payment for these supplies, when they are furnished in a hospital outpatient setting, is packaged into the APC payment rate for the procedure or service with which the items are associated.
• Certain preventive services furnished to healthy persons, such as colorectal cancer screening.
Section 4523(d)(3) of the BBA 1997 amended section 1833(a)(2)(B) of the Act to provide that we discontinue reasonable cost based payment and instead make Part B payment under the hospital outpatient PPS for certain medical and other health services when
they are furnished by other providers such as hospices, SNFs, and HHAs. Specifically, we proposed to pay under the hospital outpatient PPS for the following medical and other health services when they are furnished by a provider of services:
• Antigens (as defined in 1861(s)(2)(G) of the Act);
• Splints and casts (1861(s)(5) of the Act);
• Pneumococcal vaccine, influenza vaccine, hepatitis B vaccine (1861(s)(10) of the Act).
Upon implementation of the hospital outpatient PPS, we would make Part B payment for the above services under the outpatient PPS when they are furnished by an HHA or hospice program. We would also make payment for antigens and the vaccines under the PPS when they are furnished by CORFs. (Splints and casts furnished by CORFs are paid under the rehabilitation fee schedule.) However, this provision would not apply to services furnished by a CORF that fall within the definition of CORF services at section 1861(cc)(1) of the Act. It also would not apply to services furnished by a hospice within the scope of the hospice benefit. Nor would it apply to services furnished by HHAs to individuals under an HHA plan of treatment within the scope of the home health benefit.
d. Summary of Final Action
We received no comments about the services we proposed to include within the scope of the hospital outpatient PPS. As noted in the preceding section III.B.1, we added certain implantable items to § 419.2(b) to implement section 201(e) of the BBRA 1999.
3. Hospital Outpatient PPS Payment Indicators
In the September 8, 1998 proposed rule in the
Federal Register,
we proposed a payment status indicator for every code in the HCPCS to identify how the service or procedure described by the code would be paid under the hospital outpatient PPS. We received no comments on our proposal to assign a payment status indicator to every HCPCS code. (In section III.C.6, below, we respond to commenters who disagreed with the payment status indicator that we proposed for individual codes.) Therefore, we are implementing payment status indicators as part of the hospital outpatient PPS. Addendum B displays the final payment status indicator for each HCPCS code, including codes for incidental services that are packaged into APC payment rates. Addendum E identifies the HCPCS codes to which we have assigned payment status indicator “C” to identify inpatient services that are not payable under outpatient PPS as implemented by this final rule. We respond below, in section III.C.5, to public comments about the specific codes we classified as inpatient services in the proposed rule and our final determination regarding the payment status of those codes.
The following are the payment status indicators and description of the particular services each indicator identifies:
• We use “A” to indicate services that are paid under some other method such as the DMEPOS fee schedule or the physician fee schedule.
• We use “C” to indicate inpatient services that are not paid under the outpatient PPS.
• We use “E” to indicate services for which payment is not allowed under the hospital outpatient PPS. In some instances, the service is not covered by Medicare. In other instances, Medicare does not use the code in question, but does use another code to describe the service.
• We use “F” to indicate corneal tissue acquisition costs, which are paid separately.
• We use “G” to indicate a current drug or biological for which payment is made under the transitional pass-through.
• We use “H” to indicate a device for which payment is made under the transitional pass-through.
• We use “J” to indicate a new drug or biological for which payment is made under the transitional pass-through.
• We use “N” to indicate services that are incidental, with payment packaged into another service or APC group.
• We use “P” to indicate services that are paid only in partial hospitalization programs.
• We use “S” to indicate significant procedures for which payment is allowed under the hospital outpatient PPS but to which the multiple procedure reduction does not apply.
• We use “T” to indicate surgical services for which payment is allowed under the hospital outpatient PPS. Services with this payment indicator are the only services to which the multiple procedure payment reduction applies.
• We use “V” to indicate medical visits for which payment is allowed under the hospital outpatient PPS.
• We use “X” to indicate ancillary services for which payment is allowed under the hospital outpatient PPS.
The table below lists types of services, the hospital outpatient PPS payment status indicator assigned to each type of service, and the basis for Medicare payment for the service.

C. Description of the Ambulatory Payment Classification (APC) Groups
1. Setting Payment Rates Based on Groups of Services Rather Than on Individual Services
In our March 17, 1995 report to Congress, we recommended that groups similar to the ambulatory patient groups (APGs) developed by 3M Health Information Systems (3M) be used as the basis for the hospital outpatient PPS. We made this recommendation after examining a number of other payment systems that were already in place or under development, including DRGs that are the basis for Medicare payment for hospital inpatient services, the Medicare physician fee schedule that was implemented in 1992, and the payment groups that have been the basis for Medicare payments for ambulatory surgical center (ASC) facility services since 1982.
As provided by the BBA 1997, section 1833(t)(2)(A) of the Act requires the Secretary to develop a classification system for covered outpatient services. Section 1833(t)(2)(B) provides that this classification system may be composed of groups, so that services within each group are comparable clinically and with respect to the use of resources. The statute refers to “each such service (or group of services),” confirming that the Secretary may choose or not choose to group services.
We explain in our proposed rule that we revised the APGs, based on more recent Medicare data than that used by 3M, to create the ambulatory payment classification (APC) system. We proposed to group services identified by HCPCS codes and descriptors within APC groups as the basis for setting payment rates under the hospital outpatient PPS. We indicated that we organized the APC groups so that the services within each group would be homogeneous both clinically and in terms of resource utilization. We invited comments on our proposal to set rates on the basis of groups of services rather than on individual codes.
Comments:
Some commenters claimed that basing payment on APC groups rather than on individual services would result in underpayment for services that are more resource intensive, causing hospitals with a more resource intensive case mix to lose money. An organization representing physicians strongly opposed the use of APCs, because it believes that it is not possible to achieve an incentive-neutral, “level playing field” payment system using groups of codes or services. This organization favored replacing the APC system with a fee schedule based on individual services, similar to the Medicare physician fee schedule, as MedPAC recommends in its 1999 report to Congress. (We address the MedPAC recommendation later in this section.) The same physician organization is concerned that the broad range of services included in each APC will create an incentive for hospitals to provide lower cost services, even though a patient might require higher cost services. This organization expressed concern about the negative impact on physicians if a payment methodology similar to the APC system were applied to payment for physician services. To facilitate pricing new codes using individual services rather than APC groups, the same organization suggested that we establish a “relative value relationship in direct costs” between the new code and a comparable code, or that we consult AMA's Specialty Society RVS Updating Committee (RUC) for advice on relative cost relationships.
One major hospital association expressed its preference for a service-specific fee schedule because of the wide variation in costs represented by groups of codes. Another hospital association advocated using individual services rather than groups of services as the basis for ratesetting, but recommended, if we were to use some form of grouping, that we apply tight limits on the variations of costs for services within a group.
Response:
We understand the concerns of commenters that setting payment weights using groups of services rather than individual services could result in payment for particular services that might not fully offset the costs that hospitals incur when they furnish expensive, resource-intensive services. However, we believe these concerns are in large measure addressed by the provisions of this final rule. As we explain in section III.C.6, we significantly restructured the proposed APC groups, first in response to comments and, second, to comply with section 1833(t)(2) of the Act, as amended by the BBRA 1999, which limits the variation of costs of services classified within a group. The result is more APC groups with fewer codes and a narrower range of costs in each group. In addition, other provisions of the BBRA 1999, such as the transitional pass-throughs (see section III.D, below), and outlier payments and transitional corridors (see section III.H, below) protect hospital revenues while hospitals gain experience with the PPS.
Medicare Payment Advisory Commission (MedPAC) Recommendation
In both its March 1998 and March 1999 reports to the Congress on Medicare payment policy, MedPAC recommends that payment rates under the hospital outpatient PPS be based upon costs of individual services rather than groups of similar services to help ensure consistent payments across ambulatory settings. In its March 1999 report, MedPAC asserts its belief that the burden imposed by our proposed APC system outweighs its benefits in ambulatory settings. MedPAC gives several reasons to support its position.
• The use of groups to calculate weights masks questionable cost data for low volume and new procedures.
• Different classes of hospitals face disproportionate impacts, suggesting APC groups may not be as homogeneous as we believe.
• Grouping services will likely create additional administrative burdens for hospitals, because hospitals may have to purchase or develop new software and will experience additional education and training costs.
Response:
We carefully reviewed the concerns about using groups of services
expressed by MedPAC in its March 1998 report, and we responded to those concerns in our proposed rule (63 FR 47562). Even though MedPAC concedes in its March 1999 report that using groups to set rates has certain potential advantages, MedPAC continues to oppose using groups because, according to MedPAC, they entail considerable costs and drawbacks and necessitate “a much more complicated design logic” than would be required using a service-level fee schedule.
We do not share MedPAC's concerns. We have a high level of confidence in the ratesetting method using APC groups that we implement in this final rule with comment period. As we explain below, in section III.C.6, we have extensively restructured the APC groups to respond to comments on the proposed rule, to incorporate specific provisions of the BBRA 1999, and to correct some errors that had come to our attention. We believe that by using median costs in the calculation of group weights, we limit the extent to which infrequently performed services with suspect costs can affect the payment rate of an APC group.
As discussed below in the impact analysis (section IX of this preamble), the provisions of this final rule with comment period, which include setting rates using APC groups, alleviate to a large extent the disproportionate impacts on different classes of hospitals estimated in our proposed rule. In addition, as we explain in section III.C.6, when we restructured the APC groups, we were particularly attentive to the degree of provider concentration associated with the individual services within a group in order to avoid biasing the payment system against any subset of hospitals.
Finally, none of the commenters cited increased administrative burden as an argument against using groups. Even though we are using APC groups to set rates under the hospital outpatient PPS, hospitals will bill for services using HCPCS codes (not APCs) using the same claims forms that they use currently. Although to receive payment under the new system, hospitals will have to more fully code the services they furnish, they will not have to know to which APC the service is assigned in order to determine the payment amount. We are publishing the payment rate applicable to each HCPCS code in Addendum B of this final rule. Any burdens on hospitals necessitating additional technical assistance, training, or systems changes are more a function of implementing an entirely new payment system than of our setting rates on the basis of groups of services.
Final Action:
The payment rates implemented by this final rule with comment period are determined based on APC groups that use HCPCS codes to describe individual services. The codes assigned to an APC group are comparable clinically and in terms of resource use.
2. Packaging Under the APC System
a. Summary of Proposal
In our proposed rule, we described packaged services as those items or services that we recognized as contributing to the cost of the procedures or services in an APC group, and for which we would not make separate payment. We proposed to include as packaged services use of the operating room and recovery room, anesthesia, medical/surgical supplies, pharmaceuticals, observation, blood, intraocular lenses, casts and splints, the costs of acquiring tissue such as corneal tissue for surgical insertion and various incidental services such as venipuncture. We packaged the services (and their costs) within the APC group of procedures with which they were delivered in the base year. For a list of proposed packaged services grouped by hospital revenue centers, refer to the June 30, 1999 correction notice (64 FR 35258).
b. General Comments and Responses (Supporting or Objecting to Packaging)
Comment:
Few commenters disagreed with our proposal to aggregate into one payment the costs for a “package” of services variously related to a procedure or to the principal service being furnished. However, many commenters did object to our packaging costs for certain specific items such as expensive drugs and pharmaceuticals, observation services in the emergency department, blood and blood products, corneal tissue acquisition costs, and chemotherapy and supportive drugs. Commenters, fearful that packaging items and services will result in lower payments that do not offset the high costs of particularly expensive items, raised the prospect of dire consequences such as forcing hospitals to use only the cheapest drugs, being unable to employ oncology nurses, eliminating otherwise clinically necessary ancillary services, or not being able to hold emergency room patients for observation.
Response:
We are persuaded by commenters' arguments that packaging payment for certain expensive items and services into an APC group rate could have such a potentially negative impact as to jeopardize beneficiary access to these items and services in the hospital outpatient setting. Therefore, in response to comments, we are not packaging within an APC payment rate the costs associated with certain specified items and services. Instead, we will make a separate APC payment for these particular items and services under the outpatient PPS. However, as we explain in section III.C.2.d, we do not concur with commenters who urge separate payment for observation services; rather, we are packaging the costs in the APC for each service with which observation services were billed in our 1996 database. We discuss in further detail below, in section III.C.2.d through section III.C.2.g, and in section III.C.6, the changes that we are making to the packaging we originally proposed. We address in section III.B.1, above, the BBRA 1999 provision that requires us to package into APC group rates payment for certain implantable items and devices. In section III.D, below, we describe additional payments for certain packaged medical devices, drugs, and biologicals that are provided as transitional pass-throughs under section 201(b) of the BBRA 1999.
As we gain experience with and collect additional cost data under the hospital outpatient PPS, we will review our policy to pay separately for certain items and services that would otherwise be packaged into the APC payment. Should we decide to modify this policy, we will do so through the rulemaking process as part of our annual hospital outpatient PPS update.
MedPAC Recommendation:
In its March 1999 report to the Congress, MedPAC cites two models that Medicare uses to define a unit of payment: the DRG-based payment model for hospital inpatient services, and the Medicare physician fee schedule. MedPAC contends that services provided in the hospital outpatient setting more closely parallel those furnished in an office-based setting than those furnished as part of a hospital inpatient admission. Therefore, MedPAC recommends that, in establishing ambulatory care prospective payment systems in general, we define the unit of payment for ambulatory care facilities as an individually coded service, consisting of the primary service that is the reason for the encounter, and the necessary and essential ancillary services and supplies integral to it, including limited follow-up care if it is integral to the primary service, but not including physicians' services. MedPAC further recommends that the unit of payment be defined consistently across all ambulatory care settings.
Response:
The packaging that we proposed as the basis for determining APC payment rates and that we will implement under the hospital outpatient PPS is generally consistent with MedPAC's recommendation. However, we did not propose to include “limited follow-up services” in our packaged groups under the hospital outpatient PPS because of the difficulty of matching in our database the costs of these services with their associated primary encounter. For now, hospitals are to bill follow-up care, such as suture removal, using an appropriate medical visit code. We did not propose, nor have we included in this final rule with comment period, provision for a global period for hospital outpatient services analogous to the global period affecting payments for professional services made under the Medicare physician fee schedule.
c. Packaging of Casts and Splints
Comment:
One commenter stated that we should not package costs for casts and splints with other procedures.
Response:
We proposed to assign payment status indicator “N” to CPT codes for strapping and casting services (CPT codes 29000-29750) to designate that these are incidental services for which payment is packaged into the APC rate for another service or procedure, in this case, the repair or reduction of a fracture or dislocation. After further review, we determined that strapping and casting services can be performed independently, for example, when a cast placed as a part of a procedure must later be replaced with another cast. Therefore, we have decided that strapping and casting services will not be packaged and we are creating two APCs (0058 and 0059) to pay for these services. The BBA 1997 required that we pay under the outpatient PPS for casting and strapping services furnished in HHAs and hospices, to the extent that these services are provided and are not within the patient's plan of care.
d. Packaging of Observation Services
We received many comments urging us to pay separately for observation services, particularly when patients are seen in the emergency department. Observation service is placing a patient in an inpatient area, adjacent to the emergency department, or, according to some comments, in the intensive care unit (ICU) or coronary care unit (CCU), in order to monitor the patient while determining whether he or she needs to be admitted, have further outpatient treatment, or be discharged. After 1983, many hospitals began to rely heavily on the use of observation services when peer review organizations questioned admissions under the hospital inpatient prospective payment system. However, in some cases, patients were kept in “outpatient” observation for days or even weeks at a time. This resulted in excess payments both from the Medicare program and from beneficiaries who generally paid a higher coinsurance. In response to this practice, in November 1996, we issued instructions limiting covered observation services to no more than 48 hours except in the most extreme circumstances. However, the cost data upon which the APC system is based contain all costs for observation in 1996, including those that exceeded the 48-hour limit imposed at the end of that year. We have packaged those costs into the service with which they were furnished in the base year. Thus, APC payments for emergency room visits include the costs of observation within the payment.
Comment:
Some commenters acknowledged that being paid separately for observation following a surgical procedure was not necessary; the packaged recovery room and observation services were sufficient. However, a major concern of commenters was observation of patients with chest pain who had equivocal results on initial diagnostic testing. Commenters were concerned that the APC payment for these cases would not be adequate.
Response:
We assume that chest pain patients, such as those described by the commenters, are sent to the CCU or ICU for observation. We believe that, in general, if a patient needs to be monitored in the ICU or CCU for any length of time, then that patient should be admitted as an inpatient. Furthermore, we have never considered care furnished in an ICU or CCU to be outpatient services. Existing cost reporting instructions allow for the use of these specialty beds during a shortage of regular inpatient beds, but charges are to reflect routine care, not intensive care.
Although, as noted above, we received many comments urging that observation services be covered as a separate APC, we continue to believe that these services have been used so inappropriately in the past that we will have to gather data under the PPS before considering constructing a separate APC. We have packaged observation wherever it was billed. Roughly $139 million was identified by revenue code 762 as representing observation services. An additional $253 million was identified in revenue codes 760, 761, and 769, which could be used for either observation or treatment room use. That $253 million is also packaged. (Both figures are in 1996 dollars.)
Further analyses will be necessary on the use of observation as an adjunct to emergency treatment, as in the case of chest pain. In order to ensure that we will have sufficient data for our future analyses, hospitals must continue to bill for observation using revenue center 762 and showing hours in the units field. Observation that is billed must represent some level of active monitoring by medical personnel. It must not be billed as a way to capture room and board for outpatients. During our first review of the APC groups, we will assess whether patients with certain conditions use observation services that should be separately recognized. Thus, correct diagnosis coding is required.
e. Packaging Costs of Procuring Corneal Tissue
Comment:
We received about 2,000 comments from physicians, eye banks, and health care associations opposing our proposal to package corneal tissue acquisition costs into the APC payment for corneal transplant procedures. Most commenters argued that the payment for the procedures in proposed APC group 670, Corneal transplant, is grossly inadequate and that we have failed to recognize the high costs associated with tissue screening and testing procedures required by the Food and Drug Administration that are reflected in the fees charged by eye banks. In addition, commenters contended that we failed to recognize the wide variation in tissue acquisition costs resulting from the level of philanthropic contributions in different areas of the country and in different years. Commenters asserted that by packaging corneal tissue acquisition costs with the payment for corneal transplant surgery, we would limit beneficiary access to quality care, force eye banks that are nonprofit, low-cost operations to close, provide disincentives for philanthropic contributions, and impede our goal to increase tissue availability.
As part of their comments, the Eye Bank Association of America (EBAA) submitted a report of a study the EBAA commissioned on corneal tissue acquisition costs. The study was conducted by the Lewin Group which collected and analyzed data on corneal tissue acquisition costs incurred by 74 of EBAA's 100 members that are charitable nonprofit organizations. The report states that these 74 eye banks supplied approximately 82 percent of the corneal tissue distributed
throughout the United States in 1997. Based on the data that they collected, the Lewin Group found that the median gross acquisition cost per transplant is $1,689 in 1999 dollars. Of this amount, approximately $233 represents the national median value of donated in-kind services such as volunteer staff. The Lewin Group concluded that the proposed hospital outpatient PPS payment of $1,583 did not adequately reflect the cost of procuring corneal tissue.
Additionally, the report states that “fund raising and in-kind service values are not as well centered on their median values as the underlying cost data. Variability in fund raising and in-kind contributions not only exists between eye banks, but from year to year, within the same eye bank.” According to the study, charitable contributions in the form of cash and in-kind services represented 28 percent of the eye banks' total gross cost for tissues furnished in 1997. The Lewin Group finds that “If HCFA were to move to fee schedule or other fixed-payment rate, and pays the adjusted median Gross cost Per Transplant * * * payment of $1689, HCFA would overpay some banks and underpay others, depending on philanthropy and in-kind services which varies from community to community and from year to year. The variation is too extreme to determine a fair rate-based system, without destroying the philanthropy the community is built upon.”
Response:
Based on the concerns raised by the commenters and the data presented in the Lewin Group study, we have decided not to package payment for corneal tissue acquisition costs with the APC payment for corneal transplant surgical procedures at this time. Instead, we will make separate payment, based on the hospital's reasonable costs incurred to acquire corneal tissue. Final payment will be subject to cost report settlement. To receive payment for corneal acquisition costs, hospitals must submit a bill using HCPCS code V2785, Processing, preserving and transporting corneal tissue, and indicate the acquisition cost rather than the hospital's charge on the bill. We intend to review this policy after we have acquired updated data on corneal procedures.
f. Packaging Costs of Blood and Blood Products
Comment:
Many commenters, including the American Red Cross, a major medical association, teaching hospitals, and community oncology centers, believe that the payments we proposed for blood and blood-related products and for APCs that required the use of blood and blood-related products, were too low. Commenters claimed that the proposed payments are so much lower than actual costs that hospitals might be forced to stop providing a range of blood services, especially those more complex than a simple transfusion. The commenters were concerned that our proposed payment would not allow hospitals to furnish the most clinically appropriate blood products and services. The commenters also stated that blood and blood product exchange were not assigned to appropriate APCs, thus skewing payment rates and not recognizing the true costs of services with which blood and blood product exchange are associated. Commenters attributed this deficiency to the fact that certain blood-related products were incorrectly billed in the 1996 data we used as the basis for pricing APCs. Commenters were also concerned that we excluded procedures whose costs fell outside 3 standard deviations of the mean cost. One major organization recommended that we separate payment for blood and blood products from the service with which it is associated. This commenter also recommended separate payment for infusible blood-derived drugs, and that we base payment for transfusable blood products on costs. Some commenters recommended a transition period prior to full implementation of the proposed PPS.
Response:
Based on the recommendations of commenters, we have created separate APC groups to pay for blood and blood products. We agree with the commenters that blood use varies enough that packaging blood units with their administration could lead to inequities. Because we were not able to capture enough claims data in the base year to accurately price the blood and blood-product APCs, we have based payment rates for these APCs on data provided by commenters, including suppliers of blood and blood products. We have based payment on current costs rather than 1996 costs so that we recognize the costs of recently developed blood safety tests. The safety of the nation's blood supply is a major concern of the Department of Health and Human Services, and we want to encourage appropriate testing and follow-up care.
g. Packaging Costs for Drugs, Pharmaceuticals, and Biologicals
We proposed to package the cost of drugs, pharmaceuticals, and biologicals with APC groups because we believe drugs are usually provided in connection with some other treatment or procedure. We collected aggregate cost data on all drugs that were billed with HCPCS codes and those billed with revenue center codes, whether or not a HCPCS was entered. By so doing, we captured historical patterns of drug use within the APC groups with which the drugs were billed during the base year. However, because we did not require HCPCS coding of drugs, we could not isolate costs associated with individual drugs, some of which are very expensive even though they are rarely used and may be used by only a few hospitals. As a result, we acknowledge that our proposed APC payment rates may not fully reflect costs of very expensive drugs or biologicals.
We also proposed to create separate drug groups for chemotherapeutic agents because those were separately identified in the APG system designed by 3M. However, because we did not have bills that were coded to identify drugs individually, we were concerned that the APC groups for chemotherapeutic groups may not have completely reflected the costs of these drugs.
Comment:
Many commenters criticized the proposed APC payment rates because they were developed using cost data from 1996 that do not reflect the cost of many new drugs, pharmaceuticals, and biologicals. Some commenters expressed particular concern about oncology drugs such as paclitaxil (Taxol) and topotecan. Some advised that Taxol and carboplatin chemotherapy have become the standard treatment for ovarian carcinoma. A number of commenters believe that our proposal did not provide sufficient financial incentives to dissuade hospitals from using the older less effective chemotherapy regimens even though there is significantly greater toxicity and reduced chances of favorable outcomes associated with their use. Many commenters strongly suggested that we carve out new drugs and biologicals and those introduced after 1996 from the PPS and pay for them on a reasonable cost basis. Several commenters asserted that packaging drugs and pharmaceuticals within the APC groups understates their cost to hospitals and their value to patients.
Response:
We believe the commenters' concerns have, to a great extent, been addressed by implementation of the BBRA 1999 pass-through provisions for drugs and biologicals. Addendum K includes a complete list of all drugs, biologicals, and medical devices that are eligible for pass-through payments. We encourage interested parties to follow the process outlined below in section III.I.4 of this
preamble to submit requests for consideration of drugs, biologicals, and medical devices that may be eligible for additional payment under the transitional pass-through provision but that are not listed in Addendum K.
h. Summary of Final Action
After consideration of comments received about packaging of services and of the requirements set forth in the amendments made to section 1833(t) of the Act by section 201(b) and section 201(e) of the BBRA 1999, we have revised the package of services directly related and integral to performing a procedure or furnishing a service on an outpatient basis whose costs will determine the national payment rate for that procedure or service under the hospital outpatient PPS.
• We will package into the APC payment rate for a given procedure or service any costs incurred to furnish the following items and services: Use of an operating suite, procedure room or treatment room; use of the recovery room or area; use of an observation bed; anesthesia; medical and surgical supplies and equipment; surgical dressings; supplies and equipment for administering and monitoring anesthesia or sedation; intraocular lenses; capital-related costs; costs incurred to procure donor tissue other than corneal tissue; and, various incidental services such as venipuncture.
• In general, we will package the cost of drugs, pharmaceuticals and biologicals into the APC payment rate for the primary procedure or treatment with which they are used. Additional payment for some drugs, pharmaceuticals, and biologics may be allowed under the transitional pass-through provisions, which we explain below, in section III.D.
• We will
not
package payment for corneal tissue acquisition costs into the payment rate for corneal transplant surgical procedures at this time. We will make separate payment for these acquisition costs based on the hospital's reasonable costs incurred to acquire corneal tissue.
• We will
not
package into the APC payment rate for another procedure or service costs incurred to furnish the following items and services: blood and blood products, including anti-hemophilic agents; casting, splinting, and strapping services; immunosuppressive drugs for patients following organ transplant; and certain other high cost drugs that are infrequently administered. We have created new APC groups for these items and services, which allows separate payment to be made for them.
3. Treatment of Clinic and Emergency Department Visits
a. Provisions of the Proposed Rule
As we discussed in our proposed rule, determining payment for hospital clinic and emergency department (ED) visits requires a variety of considerations such as the following:
• The impact of packaging on setting payment rates.
• How to code visits in a manner that recognizes variations in service intensity and levels of resource consumption.
• How to keep the system administratively manageable.
• How to define critical care in terms of facility as opposed to physician input.
• Data problems associated with identifying costs from claims that list multiple services.
• How to move toward greater uniformity of payments across ambulatory settings so as to remove payment as an incentive for determining site of service.
The major issue we faced in determining payment for hospital clinic and ED visits is whether to include diagnosis as well as
Physicians' Current Procedural Terminology
(CPT) codes in setting payment rates.
In our proposed rule, we considered several approaches to setting prospective payment rates for hospital clinic and ED visits. Potential options included: (1) Using diagnosis codes only; (2) using CPT codes only; and (3) using a CPT-diagnosis code hybrid. We solicited comments on these approaches to setting payment rates for clinic and ED visits as well as comments on alternative approaches that we did not set forth in the proposed rule. In the proposed rule, we discussed in detail our assessment of the advantages and disadvantages of each approach.
In addition, we proposed to create a HCPCS code that would be used to bill when a patient presents to an ED, requests a screening, and is screened in accordance with section 1867(a) of the Act. Payment for this new code would be minimal because we included no treatment costs in the screening service. Payment for the screening APC would be made only when no additional services were furnished by the emergency department. If nonemergency treatment was furnished, the appropriate emergency department visit would be billed, and not the screening. Similarly, if the screening reveals that an emergency does exist and treatment is instituted immediately, the screening would not be billed because we would consider payment to be subsumed into the payment for further treatment.
We proposed paying for critical care as the highest level of “visit.” In our proposed rule, we stated that hospitals would use CPT code 99291 to bill for outpatient encounters in which critical care services are furnished.
We used the CPT definition of “critical care” which is the evaluation and management of the critically ill or injured patient. Under the outpatient PPS, we would allow the hospital to use CPT code 99291 in place of, but not in addition to, a code for a medical visit or for an emergency department service. Although the CPT system allows the physician to bill in 30-minute increments following the first 74-minute period of providing critical care, we proposed to pay separately for only the initial period (CPT code 99291), packaging the few instances in which the 30-minute increments (CPT code 99292) were billed. If other services, such as surgery, x-rays, or cardiopulmonary resuscitation, were furnished on the same day as the critical care services, we would allow the hospital to bill for them separately.
b. Comments and Responses
Comment:
The major hospital associations argued that none of our three proposed approaches fully explains facility resource use in connection with clinic and emergency visits. Hospitals did not see a clear benefit in the payment ranges created by using the CPT and diagnosis hybrid approach. A major medical association adamantly opposed the use of diagnosis codes. One major HMO that does not currently use CPT codes was opposed to the use of CPT codes to describe clinic and emergency visits.
Response:
In this final rule, we are not using patient diagnosis codes to compute payment rates for medical visits to clinics and emergency departments under the outpatient PPS because a number of concerns were raised about basing payment for medical visits on both HCPCS codes and ICD-9 diagnosis codes. The final payment groups for medical visits are constructed using CPT procedure codes only, which is consistent with our overall PPS grouping strategy and with the approach we have followed to establish payment groups for surgical and diagnostic services. However, we will continue to require hospitals to provide accurate diagnosis coding on claims for payment. We will continue to assess the value of using patient diagnosis for application
to our payment system for possible use in the future.
In developing medical visit APCs based on CPT procedure codes only (a change from the proposed rule), we are collapsing 31 CPT codes that define clinic and emergency visits into six groups, three each for the clinics and the emergency department. The final APC groups for clinic and emergency visits are as follows: APC 0600, Low Level Clinic Visits; APC 0601, Mid-Level Clinic Visits; APC 0602, High Level Clinic Visits; APC 0603, Interdisciplinary Team Conference; APC 0610, Low Level Emergency Visits; APC 0611, Mid-Level Emergency Visits; APC 0612, High Level Emergency Visits; and APC 0620, Critical Care.
When basing payment on CPT codes alone, the range of costs reflects hospitals' billing patterns in increasing level of intensity. However, those increasing increments are due largely to hospitals' use of “chargemaster” systems, which generate bills using predetermined charges for codes. Thus, billing patterns reflect standard bills, not the resources used in any particular case.
We had been concerned that certain hospitals' use of the lowest level code, CPT code 99201, to bill for all clinic visits would distort the data, causing inflation in both the volume and cost of low-level clinic visits, and a corresponding underreporting of mid- and high-level visits. (Costs for mid- and high-level visits would presumably have been correct, because individual hospitals would have reported appropriate charges with these codes; there simply would have been fewer reported visits at those levels.)
We have developed the weights for clinic visits by using claims data only from a subset of hospitals that billed a wider range of visits rather than relying solely on claims with CPT code 99201. We chose to use this subset of hospitals (for this purpose only) because we do not know what CPT code 99201 indicates when hospitals use it exclusively to bill all visits.
We emphasize the importance of hospitals assessing from the outset the intensity of their clinic visits and reporting codes properly based on internal assessment of the charges for those codes, rather than failing to distinguish between low-and mid-level visits “because the payment is the same.” The billing information that hospitals report during the first years of implementation of the hospital outpatient PPS will be vitally important to our revision of weights and other adjustments that affect payment in future years. We realize that while these HCPCS codes appropriately represent different levels of physician effort, they do not adequately describe nonphysician resources. However, in the same way that each HCPCS code represents a different degree of physician effort, the same concept can be applied to each code in terms of the differences in resource utilization. Therefore, each facility should develop a system for mapping the provided services or combination of services furnished to the different levels of effort represented by the codes. (The meaning of “new” and “established” pertain to whether or not the patient already has a hospital medical record number.)
We will hold each facility accountable for following its own system for assigning the different levels of HCPCS codes. As long as the services furnished are documented and medically necessary and the facility is following its own system, which reasonably relates the intensity of hospital resources to the different levels of HCPCS codes, we will assume that it is in compliance with these reporting requirements as they relate to the clinic/emergency department visit code reported on the bill. Therefore, we would not expect to see a high degree of correlation between the code reported by the physician and that reported by the facility.
Hospitals are required to use HCPCS code 99291 to report outpatient encounters in which critical care services are furnished. (See the American Medical Association's CPT 2000 coding manual for the definition of this code.) The hospital is required to use HCPCS code 99291 in place of, but not in addition to, a code for a medical visit or for an emergency department service.
We will work with the American Hospital Association and the American Medical Association to propose the establishment of appropriate facility-based patient visit codes in time for the next proposed rule.
Comment:
Several commenters expressed concern that resources expended in the emergency department are not fully explained by the codes at their disposal. One commenter pointed out that some hospitals use internal coding systems to capture differing charges based on whether or not a case requires one-on-one nursing care.
Response:
While we share commenters' concerns on this point, we remind hospitals that they can receive additional payment under the outpatient PPS for services such as diagnostic testing and administration of infused drugs, and for therapeutic procedures including resuscitation that are furnished during the course of an emergency visit. We will also pay separately for certain high cost drugs, such as the expensive “clotbuster” drugs that must be given within a short period of time following a heart attack or stroke, if these drugs are furnished during an emergency visit. Even though some ED patients will be transferred to another hospital for inpatient treatment, the hospital that administers the drugs will be paid for them. Cases that fall far outside the normal range of costs will be eligible for an outlier adjustment established by section 201(a) of the BBRA 1999. (See section III.H, below.) In addition, one of the first topics of review to be addressed by the expert outside advisory panel, required by section 201(h)(1)(B) of the BBRA 1999, will be to determine if emergency department visits can be categorized in a way that better recognizes the underlying resources, especially nursing resources, involved in the visit.
Comment:
Several commenters expressed concern about the appropriate level of payment for patients who die in the ED. One commenter believes that services furnished to these patients are resource-intensive and recommends that we continue to pay for the services on a reasonable cost basis.
Response:
We are directing fiscal intermediaries to use the following guidelines in determining how to make payment when a patient dies in the ED or is sent directly to surgery and dies there.
• If the patient dies in the ED, make payment under the outpatient PPS for services furnished.
• If the ED or other physician orders the patient to the operating room for a surgical procedure, and the patient dies in surgery, payment will be made based on the status of the patient. If the patient had been admitted as an inpatient, pay under the hospital inpatient PPS (a DRG-based payment). If the patient was not admitted as an inpatient, pay under the outpatient PPS (an APC-based payment). If the patient was not admitted as an inpatient and the procedure is designated as an inpatient-only procedure (payment status indicator “C”), no Medicare payment will be made for the procedure, but payment will be made for ED services.
Comment:
Some commenters objected to our proposal to restrict payment for critical care services to CPT code 99291 and not allow payment for CPT code 99292. One commenter recommended that we create an APC group for the additional increments of time a physician spends in critical care for which the physician may bill.
Response:
We do not believe that paying hospitals for incremental time as critical care would better reflect facility resources. The most resource-intensive period for the hospital is generally the first hour of critical care. In addition, we believe it would be burdensome for hospitals to keep track of minutes for billing purposes. Therefore, we will pay for critical care as the most resource-intensive visit possible as defined by CPT code 99291. Critical care services will be assigned to APC 0620.
Comment:
Several commenters advised that a screening code was not necessary because an emergency visit code could be billed for ED screening services.
Response:
We agree with the commenters, and we will instead use the appropriate emergency department codes for screening services (as defined in section 1867(a) of the Act). If no treatment is furnished, we would expect screening to be billed with a low-level emergency department code.
Comment:
Some commenters expressed concern about our proposal to allow hospitals to create a separate claim for each visit when two or more medical visits occur on the same day for different diagnoses. Commenters feared that this would result in our paying under the outpatient PPS for clinic care furnished at sites other than hospital outpatient departments, and that we are promoting fragmented care. One commenter was concerned that, to the extent that patients see multiple specialists, tests will be repeated unnecessarily, hospitalizations will rise, and beneficiaries and the Medicare program will be burdened with additional, unnecessary costs.
Response:
Our decision not to use diagnosis codes as a factor in determining payment for clinic visits largely negates these concerns because the need to prepare different claims for visits for different diagnoses has been eliminated. When patients are seen in different clinics on the same day, hospitals should bill using the proper codes for the level of the visits, using the units field if appropriate to reflect more than one visit at the same level.
However, we note that the comment did prompt us to develop a code for billing those visits during which numerous physicians see a patient concurrently, for example, a surgeon, medical oncologist, and radiation oncologist for a cancer patient, to discuss treatment options and to ensure that the patient is fully informed. In this instance, each physician is addressing the patient's care from a unique perspective. If several physicians see a patient concurrently in the same clinic for the same reason, the hospital would bill for one clinic visit using an appropriate visit code even though each physician would bill individually for his or her professional services. We have established a code for hospitals to use in reporting a scheduled medical conference with the patient involving a combination of at least three health care professionals, at least one of whom is a physician. That code is G0175, Scheduled interdisciplinary team conference (minimum of three, exclusive of patient care nursing staff) with patient present.
4. Treatment of Partial Hospitalization Services
As we explained in the proposed rule, partial hospitalization is an intensive outpatient program of psychiatric services provided to patients in lieu of inpatient psychiatric care. Partial hospitalization may be provided by a hospital to its outpatients or by a Medicare-certified community mental health center (CMHC). It is important to note that the services of physicians, clinical psychologists, clinical nurse specialists (CNSs), nurse practitioners (NPs), and physician assistants (PAs) furnished to partial hospitalization patients would continue to be billed separately to the carrier as professional services and are not considered to be partial hospitalization services. Thus, payment for partial hospitalization services represents the provider's overhead costs, support staff, and the services of clinical social workers (CSWs) and occupational therapists (OTs), whose professional services are considered to be partial hospitalization services for which payment is made to the provider. Including CSW and OT services reflects historical patterns of treatment billed during the base year.
Because a day of care is the unit that defines the structure and scheduling of partial hospitalization services, we proposed a per diem payment methodology for the partial hospitalization APC. We analyzed the service components billed by hospitals over the course of a billing period and determined the median hospital cost of furnishing a day of partial hospitalization. As noted in the June 30, 1999 correction notice, this analysis resulted in a proposed APC payment rate of $206.71 per day, of which $46.78 is the beneficiary's coinsurance.
We also solicited comments on a number of issues related to partial hospitalization. We asked for information on the mix of services that constitute a typical partial hospitalization day and average duration of a partial hospitalization episode, whether we should impose a minimum number of services for each covered partial hospitalization day, and whether we should establish a limit on routine outpatient mental health services furnished on a given day to equal the partial hospitalization per diem amount. Finally, we indicated that we are considering specifying a timeframe for physician recertification of need for partial hospitalization services as a method of ensuring that a patient's condition continues to require the intensity of a partial hospitalization program.
We did not receive a significant number of public comments on this issue. A summary of the comments we received and our responses follow.
Comment:
We received many similar comments from rural hospitals that operate partial hospitalization programs. The hospitals indicated that the proposed per diem amount does not cover their direct cost of providing services. Each commenter included an estimate of their partial hospitalization program cost (without depreciation or allocation of overhead costs). The estimates range from $270 to $325 per patient per day. The commenters indicated that approximately 65 to 70 percent of the costs are personnel-related.
Response:
The commenters did not indicate why their costs were higher than the per diem amount, but only that a significant proportion of their costs are related to personnel. In the future, we are committed to assessing the extent to which the per diem reflects special needs of rural hospitals. In the meantime, the BBRA 1999 includes provisions that offer relief to rural hospitals during the early years of the outpatient PPS. (See section III.H of this preamble.)
Comment:
We received several other comments regarding the proposed per diem amount. One commenter stated that the proposed per diem rate is equivalent to 3.3 psychotherapy units. The commenter believed this is an inadequate level of therapy for partial hospitalization patients and suggested that a per diem rate equal to 4 psychotherapy units would provide payment for a more appropriate level of service intensity. Several other commenters suggested that we set a single rate using a therapeutic hour of treatment (for example, the group psychotherapy APC rate) as the unit of service coupled with an overall aggregate limit for a course of treatment. These commenters estimated that a typical partial hospitalization day costs $275. Another commenter, a national association, conducted a survey of its
member hospitals which showed that the median cost per day of treatment was approximately $210. Other commenters urged us to establish separate per diem amounts for partial hospitalization programs serving geriatric beneficiaries and those serving disabled beneficiaries under age 65. They indicated that programs designed to serve geriatric beneficiaries consist of different treatment modalities that are costlier than programs that serve younger beneficiaries. One commenter stated that programs serving younger beneficiaries typically average high patient volume and therefore have much lower costs per patient day than do the programs that serve geriatric patients. Other commenters urged us to establish a half day rate, although some stated that a half-day benefit does not reduce administrative costs appreciably.
Response:
In accordance with section 1833(t)(2)(C) of the Act, the proposed per diem amount represents the national median cost of providing partial hospitalization services. We used all the data from hospital bills that included the condition code 41, which identifies the claim as partial hospitalization. Because providers do not report on the claim the specific services provided each day, we do not currently have data that would permit us to establish an aggregate limit for a course of treatment or to analyze differences in the mix of services provided to various populations. As discussed in the preamble to the proposed rule and in Transmittal 7 of the CMHC Manual (issued November 1999) and Transmittal 747 of the Hospital Manual (issued December 1999), beginning April 1, 2000, hospitals and CMHCs will be required to indicate line item dates of service on claims. Once we have accumulated these data, we will be better able to determine if refinements to the per diem methodology are warranted, including the extent to which half-days are utilized.
Comment:
Several commenters expressed concern that no CMHC data were used to establish the partial hospitalization per diem payment rate. The commenters stated that CMHC costs are significantly different from hospital-based programs and urged us to collect CMHC cost data and base payments to CMHCs on CMHC-specific information. Another commenter stated that implementing PPS for partial hospitalization services provided by CMHCs is intended to contain costs and urged us to track the impact of the PPS on CMHCs. Still another commenter expressed concern that the per diem amount is insufficient for CMHCs to provide quality services. The commenter admitted, however, that historically their service area has had limited resources to provide minimum support for the persistent and chronically mentally ill. Two commenters expressed concern about certification requirements for CMHCs. One urged us to require accreditation by a national accrediting body and another commenter noted that reliance on the statutory definition established for CMHCs under the Public Health Service Act in 1963 is no longer appropriate and urged us to redefine a CMHC for Medicare certification purposes.
Response:
Partial hospitalization services are covered services under the hospital outpatient PPS. Section 1833(a)(2)(B) of the Act provides that partial hospitalization services furnished by CMHCs are to be paid under the hospital outpatient PPS. And, section 1833(t)(2)(C) of the Act requires that we establish relative payment weights based on median (or mean, at the election of the Secretary) hospital costs determined by 1996 claims data and data from the most recent available cost reports. As stated above, we are committed to analyzing future data from hospitals and CMHCs to determine if refinements to the per diem are warranted. As we noted in the proposed rule, the Medicare partial hospitalization benefit is designed to furnish services to patients who have been discharged from inpatient psychiatric care, and partial hospitalization services are provided in lieu of continued inpatient treatment, and for patients who exhibit disabling psychiatric/psychological symptoms or experience an acute exacerbation of a severe and persistent mental disorder. Because the statute requires a physician to certify that the patient would otherwise require inpatient psychiatric care in the absence of the partial hospitalization services, we do not believe the Medicare partial hospitalization benefit was intended to provide support for the persistent and chronically mentally ill except when they are in an acute phase of their mental illness. With regard to accreditation requirements for CMHCs and substantively revising the definition of a CMHC, this final rule is not the appropriate vehicle in which to address these issues. We are, however, amending § 410.2 to remove an obsolete provision from the definition of a CMHC.
Comment:
Several commenters questioned whether the proposed per diem approach meets the definition of an APC, that is, a group of services that are comparable clinically and in resource use. They believed that partial hospitalizations vary widely in their treatment approach and cost. Therefore, creating one payment amount for all partial hospitalization days is not consistent with our proposed classification system.
Response:
We continue to believe that the structure of the average partial hospitalization day is more similar than the commenters believe. We followed the basic analytical methodology used to establish all the APC payment amounts, except that we determined that, for partial hospitalization services, the unit of service is a day. Nonetheless, requiring providers to submit claims by date of service and by service provided will allow for future analysis to determine if the APC grouping for partial hospitalization can be improved.
Comment:
One commenter expressed concern about the use of 1996 data as the basis for the per diem amount. They referenced testimony by the Inspector General that indicated a significant improvement in the accuracy of provider billing in 1998 audits. They urged us to use 1997 or 1998 cost reports by region to develop the APC rate.
Response:
Section 1833(t)(2)(C) of the Act requires that we use 1996 claims data and the most recent cost reports as the basis for ratesetting under the hospital outpatient PPS. For purposes of the final rule, we primarily used cost reports for periods beginning in FY 1997.
Comment:
Several commenters, including national industry associations, expressed concern that partial hospitalization programs are required by their individual fiscal intermediaries to meet different medical necessity and programmatic requirements. For this reason, programs vary widely in program content and resultant cost. The commenters urged us to establish national coverage criteria before implementing a PPS for partial hospitalization services. Another commenter urged us to rely on more recent claims data that identify all services provided on each date of service in order to determine the relative resource cost of various outpatient mental health treatment programs.
Response:
Section 1833(a)(2)(B) of the Act provides that partial hospitalization services are paid under section 1833(t). We will refine the system, as needed, based on our review of more specific bill data. Movement to a per diem payment methodology will necessitate changes in the medical review approach used by fiscal intermediaries. It will become necessary to ensure that all patients receive the level of service their
individual condition requires. Some patients will require days of service that cost the provider more than the per diem payment amount. Other patients may require less intensive days of service during an acute episode of partial hospitalization care or as they transition out of the partial hospitalization program. We will be developing medical review guidance for fiscal intermediaries, which we believe will lead to more consistency in medical review.
Comment:
One commenter noted that, in the past, a daily or partial-day payment approach was commonly used and was abandoned in favor of component billing for each partial hospitalization service. The commenter now believes that component billing provides a more accurate indication of the services provided to individual patients.
Response:
We believe that a per diem payment approach is a more appropriate methodology than billing for each program component. This approach is supported by the major industry groups involved with partial hospitalization and is used by other governmental and private insurers to pay for partial hospitalization program services. A per diem approach also incorporates and recognizes the cost of services that are not separately billable as outpatient psychiatric services, such as nursing services, training and education services, activity therapy, and support staff costs.
Comment:
Several commenters requested additional information on the HCPCS codes to which the partial hospitalization indicator applies and questioned how codes will group to APC 20 rather than grouping to psychotherapy APCs 91 through 94. They also asked whether substance abuse day programs will group to APC 20.
Response:
We issued revised billing instructions for partial hospitalization services provided by CMHCs in November 1999 and for hospital programs in December 1999. We instructed CMHCs to use HCPCS codes to bill for their partial hospitalization services; we required hospitals and CMHCs to report line item dates of service; and we established new HCPCS codes for occupational therapy and training and educational services furnished as a component of a partial hospitalization treatment program. We included in the instructions a complete listing of the revenue codes and HCPCS codes that may be billed as partial hospitalization services as follows:

To bill for partial hospitalization services under the hospital outpatient PPS, hospitals are to use these HCPCS and revenue codes and are to specify condition code 41 on the HCFA-1450 claim form. Before assigning a claim for payment to APC 0033 (the final APC for partial hospitalization services), the outpatient code editor (OCE) will check for errors; for example, the OCE will verify that the claim includes a mental health diagnosis, and at least three partial hospitalization HCPCS codes for each day of service, one of which must be a psychotherapy HCPCS code (other than brief). Claims that do not pass the OCE edits will undergo further prepayment review.
With regard to the comments regarding substance abuse day programs, the Medicare benefit category is partial hospitalization services. Because there is no separate benefit category for substance abuse programs, any such program would have to meet requirements established for partial hospitalization programs in order for claims to group to APC 0033, including the requirements that a physician certify that the patient would otherwise require inpatient psychiatric care in the absence of the partial hospitalization services and that the program provides active treatment.
Comment:
In regard to physician recertification, we received several comments expressing support for establishing a specific timeframe and recommending a range from 7 to 31 days.
Response:
We agree that physicians should initially certify a patient's need for partial hospitalization services and recertify continued need for this intensive level of treatment. Because partial hospitalization is the outpatient substitute for inpatient psychiatric care, we believe it is appropriate to adopt the standard currently used for inpatient psychiatric care. Therefore, in this final rule, we are amending § 424.24(e) to establish physician recertification requirements for partial hospitalization services. The initial physician certification establishing the need for partial hospitalization must be received by the partial hospitalization program upon admission. Thus, services provided to establish a patient's need for partial hospitalization services would continue to be billed to the carrier as professional services. The first recertification is required as of the 18th day of services and subsequent recertifications are required no less frequently than every 30 days. Each recertification must address the patient's response to the intensive, therapeutic interventions provided by the active treatment program which make up partial hospitalization services, changes in functioning and status of the serious psychiatric symptoms that place the patient at risk of hospitalization, and treatment plan and goals for coordination of services such as community supports and less intensive treatment options to facilitate discharge from the partial hospitalization program.
Comment:
We received several comments regarding our proposal to limit payment for less intensive outpatient mental health treatment at the partial hospitalization per diem rate. One commenter did not believe the law supports establishment of a payment ceiling and that any such action is arbitrary. Other commenters believe that treatment should be determined by the clinical needs of each patient. However, the commenters conceded that additional requirements may have to be added to the final rule to prevent duplication or overlap of partial
hospitalization and routine outpatient mental health services.
Response:
Our rationale for this proposal was that the costs associated with administering a partial hospitalization program represent the most resource intensive of all outpatient mental health treatment and, therefore, we should not pay more for a day of individual services. We are also concerned that a provider may disregard a patient's need for the intensive active treatment offered by a partial hospitalization program and opt to bill for individual services. In addition, the per diem amount represents the cost of an average day of partial hospitalization because the data used to calculate the per diem were derived from all the partial hospitalization data and include the most and the least intensive days. It would not be appropriate for a provider to obtain more payment through component billing.
Comment:
Several commenters expressed concern about staffing services that are bundled in the per diem payment and other staffing issues. One commenter stated that due to increased medical review by the fiscal intermediary, no partial hospitalization services may be furnished by unlicensed personnel. The commenter urged that the necessity for upgrades in staffing be taken into consideration in establishing a per diem rate. One commenter believes that all services, except for physician services, should be bundled into the per diem rate.
Response:
The list of covered partial hospitalization services is located in section 1861(ff) of the Act. The list includes several services such as patient education and training and activity therapy that may be provided by unlicensed but qualified staff who are specifically trained to work with the mentally ill. We note that the billing instructions issued in November 1999 (for CMHCs) and in December 1999 (for hospitals) announced a new HCPCS code for patient training and education services as a component of a partial hospitalization program. (A HCPCS code for activity therapy as part of a partial hospitalization program has been in place for several years.) Although the list also specifically references the services of social workers, trained psychiatric nurses, and other staff trained to work with psychiatric patients, there are no specific HCPCS codes for these services. Certain other partial hospitalization services, for example, individual and group psychotherapy, family counseling, occupational therapy (OT), and diagnostic services, must be provided by licensed staff, authorized by the State to provide these services.
With regard to the content and staffing of partial hospitalization programs, we believe that all the covered services listed in section 1861(ff) of the Act and the disciplines of the staff who provide the services, that is, the multidisciplinary team, are an important element in creating the therapeutic milieu that distinguishes partial hospitalization programs from other outpatient mental health treatment. We believe it would be inappropriate if providers no longer offered the full range of partial hospitalization services, especially services such as OT that continue to be bundled in the per diem amount. We plan to monitor the extent to which providers change their programming in response to implementation of the PPS. Because the data on which the per diem was based included the full range of services and the use of certain bundled professionals, we will monitor changes in services or increased use of unbundled practitioners to evaluate and update the per diem rate. In response to the comment recommending that we bundle more professional services into the per diem rate, we captured historical patterns of treatment and staffing during the base year. Thus, the partial hospitalization per diem amount is limited to the provider's overhead costs, support staff, and the services of clinical social workers and occupational therapists, whose professional services are defined as partial hospitalization services. We have amended § 410.43(b) to update the list of services that are not paid as partial hospitalization services.
Comment:
One commenter took issue with our characterizing partial hospitalization to be the result of an acute exacerbation of a beneficiary's severe and persistent mental illness for which partial hospitalization services are provided in lieu of an inpatient psychiatric admission. They urged us to clarify that admission to a partial hospitalization is based on a physician certification that the patient would otherwise require inpatient psychiatric care, but continued stay in a partial hospitalization program would serve as a maintenance program for the chronically mentally ill. The commenter raised many other concerns about how we described partial hospitalization in the proposed rule, noting specific concern with regard to active treatment, community-based support, and frequency and duration of services.
Response:
It was not our intention in the proposed rule to generate public comment on the nature and coverage of partial hospitalization under the Medicare program. Rather, the information presented has appeared in various program memoranda and was included to describe the benefit and explain the per diem payment methodology. We continue to believe that partial hospitalization is a covered Medicare benefit category only when provided as an alternative to inpatient psychiatric care for acutely mentally ill beneficiaries.
Result of Evaluation of Comments
We are adopting as final our proposal to—
• Establish a per diem payment of $202.19 for the partial hospitalization APC (APC 0033); and
• Limit the payment for outpatient mental health treatment furnished on a day of services to the partial hospitalization APC payment amount.
In addition, we are amending § 424.24(e) to establish requirements for physician recertification for partial hospitalization services.
5. Inpatient Only Procedures
In our proposed rule, we assigned payment status indicator “C” to 1,803 codes that represent procedures that our medical advisors and staff determined require inpatient care because of the invasive nature of the procedure, the need for postoperative care, or the underlying physical condition of the patient who would require the surgery. We did not assign these procedures to an APC group, and we proposed to make no payment for these services under the hospital outpatient PPS. Above, in section III.B.1.b of this preamble, we respond to the numerous general comments we received challenging both our classification of various procedures as inpatient procedures and our exclusion of these procedures from the scope of services paid under the hospital outpatient PPS.
Comment:
Commenters objected on the grounds that medical practice and new technology have allowed many procedures that formerly were performed only in the inpatient setting to be safely and effectively performed on an outpatient basis. In addition, they believe we are making decisions that should be left to the discretion of surgeons and their patients. Finally, the commenters believe that it is better for the patient if procedures are performed on an outpatient basis whenever possible. Commenters requested that we remove the payment status indicator of “inpatient only” from 195 codes and include them in an appropriate APC.
Response:
Under section 1833(t)(1)(B)(i) of the Act, the Secretary has broad authority to designate which
services fall within the definition of “covered OPD [outpatient department] services” that will be subject to payment under the prospective payment system. We believe that certain surgically invasive procedures on the brain, heart, and abdomen, such as craniotomies, coronary-artery bypass grafting, and laparotomies, indisputably require inpatient care, and therefore are outside the scope of outpatient services. Certain other procedures that we proposed as “inpatient only” may not be so clearly classified as such, but they are performed virtually always on an inpatient basis for the Medicare population. We acknowledge that emerging new technologies and innovative medical practice are blurring the difference between the need for inpatient care and the sufficiency of outpatient care for many procedures, although we are concerned that some of the procedures that commenters claim to be performing on an outpatient basis may actually have been performed with overnight postoperative care furnished in observation units. And, regardless of how a procedure is classified for purposes of payment, we expect, as we stated in our proposed rule, that in every case the surgeon and the hospital will assess the risk of a procedure or service to the individual patient, taking site of service into account, and will act in that patient's best interests.
After a careful review of comments by our medical advisors and staff, we have assigned to APC groups certain procedures that we had proposed as inpatient only. We made some changes because we were convinced by commenters' arguments that certain procedures are often performed safely in the outpatient setting; others because we believe that the simplest procedure described by the code may be performed safely in the outpatient setting; and yet others because they were related to codes we moved (for example, the radiologic part of an interventional cardiology procedure). The procedures we moved to the outpatient APCs include codes from within the following families: Explorations of penetrating wounds; repairs of some cranial and facial fractures; planned tracheostomies; diagnostic thoracoscopies; some insertion/removal/replacement of pacemakers, pulse generators, electrodes and cardioverter-defibrillators; embolectomies and thrombectomies; transluminal balloon angioplasty and peripheral atherectomy; transcatheter therapies; bone marrow transplantation; gastrostomies; percutaneous nephrostolithotomy; surgical laparoscopies, including cholecystectomies; ovarian biopsies; and surgeries on the orbit. Although we are moving these procedures into APC groups and th
