AGENCY:

Centers for Medicare & Medicaid Services (CMS), HHS.

ACTION:

Final rule with comment period and final rule.

SUMMARY:

This final rule with comment period revises the Medicare hospital outpatient prospective payment system to implement applicable statutory requirements and changes arising from our continuing experience with this system, and to implement certain related provisions of the Medicare Prescription Drug, Improvement, and Modernization Act (MMA) of 2003 and the Deficit Reduction Act (DRA) of 2005. In this final rule with comment period, we describe changes to the amounts and factors used to determine the payment rates for Medicare hospital outpatient services paid under the prospective payment system. These changes are applicable to services furnished on or after January 1, 2007. In addition, this final rule with comment period implements future CY 2009 required reporting on quality measures for hospital outpatient services paid under the prospective payment system.

This final rule with comment period revises the current list of procedures that are covered when furnished in a Medicare-approved ambulatory surgical center (ASC), which are applicable to services furnished on or after January 1, 2007.

This final rule with comment period revises the emergency medical screening requirements for critical access hospitals (CAHs).

This final rule with comment period supports implementation of a restructuring of the contracting entities responsibilities and functions that support the adjudication of Medicare fee-for-service (FFS) claims. This restructuring is directed by section 1874A of the Act, as added by section 911 of the MMA. The prior separate Medicare intermediary and Medicare carrier contracting authorities under Title XVIII of the Act have been replaced with the Medicare Administrative Contractor (MAC) authority.

This final rule continues to implement the requirements of the DRA that require that we expand the “starter set” of 10 quality measures that we used in FY 2005 and FY 2006 for the hospital inpatient prospective payment system (IPPS) Reporting Hospital Quality Data for the Annual Payment Update (RHQDAPU) program. We began to adopt expanded measures effective for payments beginning in FY 2007. In this rule, we are finalizing additional quality measures for the expanded set of measures for FY 2008 payment purposes. These measures include the HCAHPS survey, as well as Surgical Care Improvement Project (SCIP, formerly Surgical Infection Prevention (SIP)), and Mortality quality measures.

DATES:

Effective Date:
The provisions of these final rules are effective on January 1, 2007.

Comment Period:
We will consider comments on the payment classification assigned to HCPCS codes identified in Addendum B with the NI comment code, and other areas specified throughout the preamble, at the appropriate address, as provided below, no later than 5 p.m. January 23, 2007.

I. Background for the OPPS

A. Legislative and Regulatory Authority for the Hospital Outpatient Prospective Payment System

When the Medicare statute was originally enacted, Medicare payment for hospital outpatient services was based on hospital-specific costs. In an effort to ensure that Medicare and its beneficiaries pay appropriately for services and to encourage more efficient delivery of care, the Congress mandated replacement of the reasonable cost-based payment methodology with a prospective payment system (PPS). The Balanced Budget Act (BBA) of 1997 (Pub. L. 105-33), added section 1833(t)

to the Social Security Act (the Act) authorizing implementation of a PPS for hospital outpatient services (OPPS).

The Medicare, Medicaid, and SCHIP Balanced Budget Refinement Act (BBRA) of 1999 (Pub. L. 106-113), made major changes in the hospital OPPS. The Medicare, Medicaid, and SCHIP Benefits Improvement and Protection Act (BIPA) of 2000 (Pub. L. 106-554), made further changes in the OPPS. Section 1833(t) of the Act was also amended by the Medicare Prescription Drug, Improvement, and Modernization Act (MMA) of 2003 (Pub. L. 108-173). The Deficit Reduction Act (DRA) of 2005 (Pub. L. 109-171), enacted on February 8, 2006, made additional changes in the OPPS. A discussion of the provisions contained in Pub. L. 109-171 that are specific to the calendar year (CY) 2007 OPPS is included in section II.F. of this preamble.

The OPPS was first implemented for services furnished on or after August 1, 2000. Implementing regulations for the OPPS are located at 42 CFR Part 419.

Under the OPPS, we pay for hospital outpatient services on a rate-per-service basis that varies according to the ambulatory payment classification (APC) group to which the service is assigned. We use Healthcare Common Procedure Coding System (HCPCS) codes (which include certain Current Procedural Terminology (CPT) codes) and descriptors to identify and group the services within each APC group. The OPPS includes payment for most hospital outpatient services, except those identified in section I.B. of this preamble. Section 1833(t)(1)(B)(ii) of the Act provides for Medicare payment under the OPPS for hospital outpatient services designated by the Secretary (which includes partial hospitalization services furnished by community mental health centers (CMHCs)) and hospital outpatient services that are furnished to inpatients who have exhausted their Part A benefits or who are otherwise not in a covered Part A stay. Section 611 of Pub. L. 108-173 added provisions for Medicare coverage of an initial preventive physical examination, subject to the applicable deductible and coinsurance, as an outpatient department service, payable under the OPPS.

The OPPS rate is an unadjusted national payment amount that includes the Medicare payment and the beneficiary copayment. This rate is divided into a labor-related amount and a nonlabor-related amount. The labor-related amount is adjusted for area wage differences using the inpatient hospital wage index value for the locality in which the hospital or CMHC is located.

All services and items within an APC group are comparable clinically and with respect to resource use (section 1833(t)(2)(B) of the Act). In accordance with section 1833(t)(2) of the Act, subject to certain exceptions, services and items within an APC group cannot be considered comparable with respect to the use of resources if the highest median (or mean cost, if elected by the Secretary) for an item or service in the APC group is more than 2 times greater than the lowest median cost for an item or service within the same APC group (referred to as the “2 times rule”). In implementing this provision, we use the median cost of the item or service assigned to an APC group.

Special payments under the OPPS may be made for new technology items and services in one of two ways. Section 1833(t)(6) of the Act provides for temporary additional payments which we refer to as “transitional pass-through payments” for at least 2 but not more than 3 years for certain drugs, biological agents, brachytherapy devices used for the treatment of cancer, and categories of other medical devices. For new technology services that are not eligible for transitional pass-through payments and for which we lack sufficient data to appropriately assign them to a clinical APC group, we have established special APC groups based on costs, which we refer to as new technology APCs. These new technology APCs are designated by cost bands which allow us to provide appropriate and consistent payment for designated new procedures that are not yet reflected in our claims data. Similar to pass-through payments, an assignment to a new technology APC is temporary; that is, we retain a service within a new technology APC until we acquire sufficient data to assign it to a clinically appropriate APC group.

B. Excluded OPPS Services and Hospitals

Section 1833(t)(1)(B)(i) of the Act authorizes the Secretary to designate the hospital outpatient services that are paid under the OPPS. While most hospital outpatient services are payable under the OPPS, section 1833(t)(1)(B)(iv) of the Act excludes payment for ambulance, physical and occupational therapy, and speech-language pathology services, for which payment is made under a fee schedule. Section 614 of Pub. L. 108-173 amended section 1833(t)(1)(B)(iv) of the Act to exclude OPPS payment for screening and diagnostic mammography services. The Secretary exercised the authority granted under the statute to exclude from the OPPS those services that are paid under fee schedules or other payment systems. Such excluded services include, for example, the professional services of physicians and nonphysician practitioners paid under the Medicare Physician Fee Schedule (MPFS); laboratory services paid under the clinical diagnostic laboratory fee schedule; services for beneficiaries with end-stage renal disease (ESRD) that are paid under the ESRD composite rate; and, services and procedures that require an inpatient stay that are paid under the hospital inpatient prospective payment system (IPPS). We set forth the services that are excluded from payment under the OPPS in § 419.22 of the regulations.

Under § 419.20(b) of the regulations, we specify the types of hospitals and entities that are excluded from payment under the OPPS. These excluded entities include Maryland hospitals, but only for services that are paid under a cost containment waiver in accordance with section 1814(b)(3) of the Act; critical access hospitals (CAHs); hospitals located outside of the 50 States, the District of Columbia, and Puerto Rico; and Indian Health Service hospitals.

C. Prior Rulemaking

On April 7, 2000, we published in the
Federal Register
a final rule with comment period (65 FR 18434) to implement a prospective payment system for hospital outpatient services. The hospital OPPS was first implemented for services furnished on or after August 1, 2000. Section 1833(t)(9) of the Act requires the Secretary to review certain components of the OPPS not less often than annually and to revise the groups, relative payment weights, and other adjustments to take into account changes in medical practice, changes in technology, and the addition of new services, new cost data, and other relevant information and factors.

Since initially implementing the OPPS, we have published final rules in the
Federal Register
annually to implement statutory requirements and changes arising from our experience with this system. We last published such a document on November 10, 2005 (70 FR 68516). In that final rule with comment period, we revised the OPPS to update the payment weights and conversion factor for services payable under the CY 2006 OPPS on the basis of claims data from January 1, 2004, through December 31, 2004, and to implement certain provisions of Pub. L. 108-173. In addition, we responded to public comments received on the provisions of November 15, 2004 final rule with comment period pertaining to

the APC assignment of HCPCS codes identified in Addendum B of that rule with the new interim (NI) comment indicators; and public comments received on the July 25, 2005 OPPS proposed rule for CY 2006 (70 FR 42674).

We published a correction of the November 10, 2005 final rule with comment period on December 23, 2005 (70 FR 76176). This correction document corrected a number of technical errors that appeared in the November 10, 2005 final rule with comment period.

D. APC Advisory Panel

1. Authority of the APC Panel

Section 1833(t)(9)(A) of the Act, as amended by section 201(h) of the BBRA, requires that we consult with an outside panel of experts to review the clinical integrity of the payment groups and their weights under the OPPS. The Act further specifies that the panel will act in an advisory capacity. The Advisory Panel on Ambulatory Payment Classification (APC) Groups (the APC Panel), discussed under section I.D.2. of this preamble, fulfills these requirements. The APC Panel is not restricted to using data compiled by CMS and may use data collected or developed by organizations outside the Department in conducting its review.

2. Establishment of the APC Panel

On November 21, 2000, the Secretary signed the initial charter establishing the APC Panel. This expert panel, which may be composed of up to 15 representatives of providers subject to the OPPS (currently employed full-time, not as consultants, in their respective areas of expertise), reviews and advises CMS about the clinical integrity of the APC groups and their weights. For purposes of this Panel, consultants or independent contractors are not considered to be full-time employees. The APC Panel is technical in nature and is governed by the provisions of the Federal Advisory Committee Act (FACA). Since its initial chartering, the Secretary has twice renewed the APC Panel's charter: on November 1, 2002, and on November 1, 2004. The current charter indicates, among other requirements, that the APC Panel continues to be technical in nature; is governed by the provisions of the FACA; may convene up to three meetings per year; has a Designated Federal Officer (DFO); and is chaired by a Federal official who also serves as a CMS medical officer.

The current APC Panel membership and other information pertaining to the Panel, including its charter,
Federal Register
notices, meeting dates, agenda topics, and meeting reports can be viewed on the CMS Web site at
http://www.cms.hhs.gov/FACA/ 05AdvisoryPanelonAmbulatory PaymentClassification Groups.as#TopOFPage.

3. APC Panel Meetings and Organizational Structure

The APC Panel first met on February 27, February 28, and March 1, 2001. Since that initial meeting, the APC Panel has held 10 subsequent meetings, with the last meeting taking place on August 23 and 24, 2006. (The APC Panel did not meet on August 25, 2006, as announced in the meeting notice published on June 23, 2006 (71 FR 36118).) Prior to each meeting, we publish a notice in the
Federal Register
to announce the meeting and, when necessary, to solicit and announce nominations for APC Panel membership.

The APC Panel has established an operational structure that, in part, includes the use of three subcommittees to facilitate its required APC review process. The three current subcommittees are the Data Subcommittee, the Observation Subcommittee, and the Packaging Subcommittee. The Data Subcommittee is responsible for studying the data issues confronting the APC Panel and for recommending options for resolving them. The Observation Subcommittee reviews and makes recommendations to the APC Panel on all issues pertaining to observation services paid under the OPPS, such as coding and operational issues. The Packaging Subcommittee studies and makes recommendations on issues pertaining to services that are not separately payable under the OPPS, but are bundled or packaged APC payments. Each of these subcommittees was established by a majority vote of the APC Panel during a scheduled APC Panel meeting and their continuation as subcommittees was approved at the August 2006 APC Panel meeting. All subcommittee recommendations are discussed and voted upon by the full APC Panel.

Discussions of the recommendations resulting from the APC Panel's March 2006 and August 2006 meetings are included in the sections of this preamble that are specific to each recommendation. For discussions of earlier APC Panel meetings and recommendations, we reference previous hospital OPPS final rules or the Web site mentioned earlier in this section.

E. Provisions of the Medicare Prescription Drug, Improvement, and Modernization Act of 2003

The Medicare Prescription Drug, Improvement, and Modernization Act (MMA) of 2003, Pub. L. 108-173, made changes to the Act relating to the Medicare OPPS. In the January 6, 2004 interim final rule with comment period and the November 15, 2004 final rule with comment period, we implemented provisions of Pub. L. 108-173 relating to the OPPS that were effective for services provided in CY 2004 and CY 2005, respectively. In the November 10, 2005 final rule with comment period, we implemented provisions of Pub. L. 108-173 relating to the OPPS that went into effect for services provided in CY 2006 (70 FR 68521). We note below those provision of Pub. L. 108-173 that will expire at the end of CY 2006.

1. Reduction in Threshold for Separate APCs for Drugs

Section 621(a)(2) of Pub. L. 108-173 amended section 1833(t)(16) of the Act to set a threshold of $50 per administration for the establishment of separate APCs for drugs and biologicals furnished from January 1, 2005, through December 31, 2006. Because this statutory provision will no longer be in effect for CY 2007, we have included in section V. of this preamble a discussion of the methodology that we will use to determine a threshold for establishing separate APCs for drugs and biologicals for CY 2007.

2. Special Payment for Brachytherapy

Section 621(b)(1) of Pub. L. 108-173 amended section 1833(t)(16) of the Act to require that payment for brachytherapy devices consisting of a seed or seeds (or radioactive source) furnished on or after January 1, 2004, and before January 1, 2007, be paid based on the hospital's charge for each device furnished, adjusted to cost. Because this statutory provision will no longer be in effect for CY 2007, we discuss our methodology for payment for brachytherapy devices for CY 2007 in section VII.B. of this preamble.

F. Provisions of the Deficit Reduction Act (DRA) of 2005

The Deficit Reduction Act (DRA) of 2005, Pub. L. 109-171, enacted on February 8, 2006, included three provisions affecting the OPPS, as discussed below.

1. 3-Year Transition of Hold Harmless Payments

Section 5105 of Pub. L. 109-171 provides a 3-year transition of hold harmless OPPS payments for hospitals

located in a rural area with not more than 100 beds that are not defined as sole community hospitals (SCHs). This provision provides an increased payment for such hospitals for covered OPD services furnished on or after January 1, 2006, and before January 1, 2009, if the OPPS payment they receive is less than the pre-BBA payment amount that they would have received for the same covered OPD services. This provision specifies that, in such cases, the amount of payment to the specified hospitals shall be increased by the applicable percentage of such difference. Section 5105 specifies the applicable percentage as 95 percent for CY 2006, 90 percent for CY 2007, and 85 percent for CY 2008. This provision is discussed in section II.F.1. of the preamble.

2. Medicare Coverage of Ultrasound Screening for Abdominal Aortic Aneurysms (AAAs)

Section 5112 of Pub. L. 109-171 amended section 1861 of the Act to include coverage of ultrasound screening for abdominal aortic aneurysms for certain individuals on or after January 1, 2007. The provision will apply to individuals (a) who receive a referral for such an ultrasound screening as a result of an initial preventive physical examination; (b) who have not been previously furnished with an ultrasound screening under Medicare; and (c) who have a family history of abdominal aortic aneurysm or manifest risk factors included in a beneficiary category recommended for screening (as determined by the United States Preventive Services Task Force). Ultrasound screening for abdominal aortic aneurysm will be included in the initial preventive physical examination. Section 5112 also added ultrasound screening for abdominal aortic aneurysm to the list of services for which the beneficiary deductible does not apply. These amendments apply to services furnished on or after January 1, 2007. See section XIII.B. of this preamble for a detailed discussion of this provision.

3. Colorectal Cancer Screening

Section 5113 of Pub. L. 109-171 amended section 1833(b) of the Act to add colorectal cancer screening to the list of services for which the beneficiary deductible does not apply. This provision applies to services furnished on or after January 1, 2007. See the Medicare Physician Fee Schedule (MPFS) CY 2007 final rule for a detailed discussion of this provision.

G. Summary of the Provisions of the CY 2007 OPPS Proposed Rule

On August 23, 2006, we published a proposed rule in the
Federal Register
(71 FR 49506) that set forth proposed changes to the Medicare hospital OPPS for CY 2007 to implement statutory requirements and changes arising from our continuing experience with the system and to implement certain provisions of Pub. L. 109-171 specified in sections II.F.1. and XIII.B. of this preamble. We also proposed to revise the standard for critical access hospital personnel that are allowed to perform emergency medical screenings. In addition, we proposed changes to the Medicare ASC payment system for CY 2007 and CY 2008 and to the way we process fee-for-service (FFS) claims under Medicare Part A and Part B.

Finally, we set forth a proposed rule seeking comments on the RHQDAPU program under the Medicare hospital IPPS for FY 2008. These changes will be effective for payments beginning with FY 2008. The following is a summary of the major changes included in the CY 2007 OPPS proposed rule:

1. Updates to the OPPS' Payments for CY 2007

In the proposed rule, we set forth—

• The methodology used to recalibrate the proposed APC relative payment weights and the proposed median costs for CY 2007.

• The proposed payment for partial hospitalization, including the proposed separate threshold for outlier payments for CMHCs.

• The proposed update to the conversion factor used to determine payment rates under the OPPS for CY 2007.

• The proposed retention of our current policy to apply the IPPS wage indices to wage adjust the APC median costs in determining the OPPS payment rate and the copayment standardized amount for CY 2007.

• The proposed update of statewide average default cost-to-charge ratios.

• Proposed changes relating to the hold harmless payment provision and § 419.70(d).

• Proposed changes relating to payment for rural SCHs, including Essential Access Community Hospitals (EACHs) for CY 2007.

• The proposed retention of our current policy for calculating hospital outpatient outlier payments for CY 2007.

• Calculation of the proposed national unadjusted Medicare OPPS payment.

• The proposed beneficiary copayment for OPPS services for CY 2007.

2. Ambulatory Payment Classification (APC) Group Policies

In the proposed rule, we discussed establishing a number of new APCs and making changes to the assignment of HCPCS codes under a number of existing APCs based on our analyses of Medicare claims data and recommendations of the APC Panel. We also discussed the application of the 2 times rule and proposed exceptions to it; proposed changes for specific APCs; proposed movement of procedures from the New Technology APCs; and the proposed additions of new procedure codes to the APC groups.

3. Payment Changes for Devices

In the proposed rule, we discussed proposed changes to the device-dependent APCs and to payment for pass-through devices. We also discussed the proposed payment policy for devices that are replaced without cost or credit to the hospital for a replaced device and the proposed related regulation under § 419.45.

4. Payment Changes for Drugs, Biologicals, and Radiopharmaceuticals

In the proposed rule, we discussed proposed payment changes for drugs, biologicals, and radiopharmaceuticals.

5. Estimate of Transitional Pass-Through Spending in CY 2007 for Drugs, Biologicals, and Devices

In the proposed rule, we discussed the proposed methodology for estimating total pass-through spending and whether there should be a pro rata reduction for transitional pass-through drugs, biologicals, radiopharmaceuticals, and categories of devices for CY 2007.

6. Brachytherapy Payment Changes

In the proposed rule, we included a discussion of our proposal concerning coding and payment for the sources of brachytherapy.

7. Coding and Payment for Drugs Administration

In the proposed rule, we discussed our proposed coding and payment changes for drug administration services.

8. Hospital Coding and Payments for Visits

In the proposed rule, we discussed our analyses of various guidelines for coding hospital visits and the proposed HCPCS codes and payment policy for those visits.

9. Payment for Blood and Blood Products

In the proposed rule, we discussed our proposed criteria and coding changes for the blood and blood products.

10. Payment for Observation Services

In the proposed rule, we discussed our proposed continuation of applying the criteria for separate payment for observation services and the coding methodology for observation services implemented in CY 2006.

11. Procedures That Will Be Paid Only as Inpatient Services

In the proposed rule, we discussed the procedures that we proposed to remove from the inpatient list and assign to APCs.

12. Nonrecurring Policy Changes

In the proposed rule, we discussed a proposed technical change to § 419.21(d) of the regulations related to Comprehensive Outpatient Rehabilitation Facility (CORF) services and proposed coding and payment for ultrasound screening for abdominal aortic aneurysms (AAAs) as a new service paid under the OPPS in CY 2007.

13. Emergency Medical Screening in Critical Access Hospitals (CAHs)

In the proposed rule, we discussed our proposal to revise § 485.618(d) of the regulations pertaining to the standards for critical access hospital personnel available to perform emergency medical screening services.

14. Payment Status and Comment Indicator Assignments

15. OPPS Policy and Payment Recommendations

In the proposed rule, we addressed recommendations made by MedPAC, the APC Panel, and the GAO regarding the OPPS for CY 2007.

16. Policies Affecting Ambulatory Surgical Centers (ASCs) for CY 2007

In the proposed rule, we discussed changes to the ASC list of covered procedures for CY 2007; implementation of section 5103 of Pub. L. 108-173; our proposal for modifying the current ASC process for adjusting payment for new technology intraocular lenses; and related regulatory changes.

17. Revised ASC Payment System for Implementation January 1, 2008

In the proposed rule, we set forth our proposal to revise the current ASC payment system in accordance with Pub. L. 108-173, effective January 1, 2008. We note that we are not finalizing this proposal in this final rule with comment period. Rather, we will issue a separate document in the
Federal Register
that will address public comments received and finalize the ASC payment system effective January 1, 2008.

18. Medicare Contracting Reform Mandate

In the proposed rule, we set forth changes to the way we process FFS claims under Medicare Part A and Part B.

19. Reporting Quality Data for Improved Quality and Costs Under the OPPS

In the proposed rule, we proposed to adapt the quality improvement mechanism provided by the IPPS RHQDAPU program for use under the OPPS.

20. Promoting Effective Use of Health Information Technology

In the proposed rule, we discussed our plans to promote and adopt effective use of health information technology to improve the quality of care for Medicare beneficiaries.

21. Health Care Information Transparency Initiative

In the proposed rule, we announced our plans to launch a major health care transparency initiative in 2006.

22. Additional Quality Measures and Procedures for Hospital Reporting of Quality Data for FY 2008 IPPS Annual Payment Update

In the proposed rule, we discussed our proposal to expand the IPPS Reporting Hospital Quality Data for Annual Payment program measurement set for FY 2008 beyond the measures adopted for the FY 2007 IPPS update.

23. Impact Analysis

In the proposed rule, we set forth an analysis of the impact that the proposed changes will have on affected entities and beneficiaries.

H. Public Comments Received in Response to the CY 2007 OPPS Proposal Rule and on the Reporting Hospital Quality Data for FY 2008 IPPS Annual Payment Update Program—HCAHPS Survey, SCIP, and Mortality Proposed Rule

We received approximately 1,100 timely items of correspondence containing multiple comments on the CY 2007 OPPS proposed rule. We note that we received some comments that were outside of the scope of the CY 2007 OPPS proposed rule. These comments are not addressed in the CY 2007 final rule. We also received approximately 20 timely items of correspondence on Reporting Hospital Quality Data for FY 2008 Inpatient Prospective Payment System Annual Payment Update Program—HCAHPS Survey, SCIP, and Mortality proposed rule. Summaries of the public comments and our responses to those comments are set forth under the appropriate headings.

I. Public Comments Received on the November 10, 2005 OPPS Final Rule with Comment Period

We received approximately 41 timely items of correspondence on the November 10, 2005 OPPS final rule with comment period, some of which contained multiple comments on the APC assignment of HCPCS codes identified with the NI comment indicator in Addendum B of that final rule with comment period. Summaries of those public comments and our responses to those comments are set forth in the various sections under the appropriate headings.

II. Updates Affecting OPPS Payments for CY 2007

A. Recalibration of APC Relative Weights for CY 2007

1. Database Construction

a. Database Source and Methodology

Section 1833(t)(9)(A) of the Act requires that the Secretary review and revise the relative payment weights for APCs at least annually. In the April 7, 2000 OPPS final rule with comment period (65 FR 18482), we explained in detail how we calculated the relative payment weights that were implemented on August 1, 2000, for each APC group. Except for some reweighting due to a small number of APC changes, these relative payment weights continued to be in effect for CY 2001. This policy is discussed in the November 13, 2000 interim final rule (65 FR 67824 through 67827).

In the CY 2007 OPPS proposed rule, we proposed to use the same basic methodology that we described in the April 7, 2000 final rule with comment period to recalibrate the APC relative payment weights for services furnished on or after January 1, 2007, and before January 1, 2008. That is, we would recalibrate the relative payment weights for each APC based on claims and cost report data for outpatient services. We proposed to use the most recent available data to construct the database for calculating APC group weights. For the purpose of recalibrating the APC relative payment weights for CY 2007, we used approximately 142.5 million final action claims for hospital OPD services furnished on or after January 1, 2005, and before January 1, 2006. Of the 142.5 million final action claims for services provided in hospital outpatient settings, 110.2 million claims were of the type of bill potentially appropriate for use in setting rates for OPPS services (but did not necessarily contain services payable under the OPPS). Of the 110.2 million claims, approximately 51.7 million were not for services paid under the OPPS or were excluded as not appropriate for use (for example, erroneous cost-to-charge ratios or no HCPCS codes reported on the claim). We were able to use 54.1 million whole claims of the remaining 58.5 million claims to set the OPPS APC relative weights for CY 2007 OPPS. From the 54.1 million whole claims, we created 98.5 million single records, of which 68.5 million were “pseudo” single claims (created from multiple procedure claims using the process we discuss in this section).

As proposed, the final APC relative weights and payments for CY 2007 in Addenda A and B to this final rule with comment period were calculated using claims from this period that had been processed before June 30, 2006, and continue to be based on the median hospital costs for services in the APC groups. We selected claims for services paid under the OPPS and matched these claims to the most recent cost report filed by the individual hospitals represented in our claims data.

Comment:
Several commenters supported the use of the most recent claims and cost report data to calculate the median costs for use in the CY 2007 OPPS.

Response:
We appreciate the commenters' support and have used the claims for services paid under the CY 2005 OPPS as processed through the common working file as of June 30, 2006, in the calculation of the median costs on which the CY 2007 OPPS rates are based. In addition, we have used the most recently submitted cost report data as reported to the HCRIS system as of June 30, 2006, to calculate the cost-to-charge ratios (CCRs) used to reduce the billed charges to costs for purposes of calculating the median costs on which the CY 2007 OPPS rates are based.

After carefully considering all comments received, we are finalizing our data source and methodology for the recalibration of CY 2007 APC relative payment weights as proposed without modification, as described in this section.

b. Use of Single and Multiple Procedure Claims

For CY 2007, we proposed to continue to use single procedure claims to set the medians on which the APC relative payment weights would be based. We have received many requests asking that we ensure that the data from claims that contain charges for multiple procedures are included in the data from which we calculate the relative payment weights. Requesters believe that relying solely on single procedure claims to recalibrate APC relative payment weights fails to take into account data for many frequently performed procedures, particularly those commonly performed in combination with other procedures. They believe that, by depending upon single procedure claims, we base relative payment weights on the least costly services, thereby introducing downward bias to the medians on which the weights are based.

We agree that, optimally, it is desirable to use the data from as many claims as possible to recalibrate the APC relative payment weights, including those with multiple procedures. We generally use single procedure claims to set the median costs for APCs because we are, so far, unable to ensure that packaged costs can be appropriately allocated across multiple procedures performed on the same date of service. However, by bypassing specified codes that we believe do not have significant packaged costs, we are able to use more data from multiple procedure claims. In many cases, this enables us to create multiple “pseudo” single claims from claims that, as submitted, contained multiple separately paid procedures on the same claim. For the CY 2007 OPPS, we proposed to use the date of service on the claims and a list of codes to be bypassed to create “pseudo” single claims from multiple procedure claims, as we did in recalibrating the CY 2006 APC relative payment weights. We refer to these newly created single procedure claims as “pseudo” single claims because they were submitted by providers as multiple procedure claims.

For CY 2003, we created “pseudo” single claims by bypassing HCPCS codes 93005 (Electrocardiogram, tracing), 71010 (Chest x-ray), and 71020 (Chest x-ray) on a submitted claim. However, we did not use claims data for the bypassed codes in the creation of the median costs for the APCs to which these three codes were assigned because the level of packaging that would have remained on the claim after we selected the bypass code was not apparent and, therefore, it was difficult to determine if the medians for these codes would be correct.

For CY 2004, we created “pseudo” single claims by bypassing these three codes and also by bypassing an additional 269 HCPCS codes in APCs. We selected these codes based on a clinical review of the services and because it was presumed that these codes had only very limited packaging and could appropriately be bypassed for the purpose of creating “pseudo” single claims. The APCs to which these codes were assigned were varied and included mammography, cardiac rehabilitation, and Level I plain film x-rays. To derive more “pseudo” single claims, we also split the claims where there were dates of service for revenue code charges on that claim that could be matched to a single procedure code on the claim on the same date.

For the CY 2004 OPPS, as in CY 2003, we did not include the claims data for the bypassed codes in the creation of the APCs to which the 269 codes were assigned because, again, we had not established that such an approach was appropriate and would aid in accurately estimating the median costs for those APCs. For CY 2004, from approximately 16.3 million otherwise unusable claims, we used approximately 9.5 million multiple procedure claims to create approximately 27 million “pseudo” single claims. For CY 2005, we identified 383 bypass codes and from approximately 24 million otherwise unusable claims, we used approximately 18 million multiple procedure claims to create approximately 52 million “pseudo” single claims. For CY 2005, we used the claims data for the bypass codes combined with the single procedure claims to set the median costs for the bypass codes.

For CY 2006, we continued using the codes on the CY 2005 OPPS bypass list and expanded it to include 404 bypass codes, including 3 bladder catheterization codes (CPT codes 51701, 51702, and 51703), which did not meet the empirical criteria discussed below for the selection of bypass codes. We added these three codes to the CY 2006

bypass list because a decision to change their payment status from packaged to separately paid would have resulted in a reduction of the number of single bills on which we could base median costs for other major separately paid procedures that were billed on the same claim with these three procedure codes. That is, single bills which contained other procedures would have become multiple procedure claims when these bladder catheterization codes were converted to separately paid status. We believed and continue to believe that bypassing these three codes does not adversely affect the medians for other procedures because we believe that when these services are performed on the same day as another separately paid service, any packaging that appears on the claim would be appropriately associated with the other procedure and not with these codes.

Consequently, for CY 2006, we identified 404 bypass codes for use in creating “pseudo” single claims and used some part of 90 percent of the total claims that were eligible for use in OPPS ratesetting and modeling in developing the final rule with comment period. This process enabled us to use, for the CY 2006 OPPS, 88 million single bills for ratesetting: 55 million “pseudo” singles and 34 million “natural” single bills (bills that were submitted containing only one separately payable major HCPCS code). (These numbers do not sum to 88 million because more than 800,000 single bills were removed when we trimmed at the HCPCS level at +/-3 standard deviations from the geometric mean.)

For CY 2007, we proposed to continue using date-of-service matching as a tool for creation of “pseudo” single claims and to continue the use of a bypass list to create “pseudo” single claims. The process we proposed for the CY 2007 OPPS resulted in our being able to use some part of 92.6 percent of the total claims that are eligible for use in the OPPS ratesetting and modeling in developing this final rule with comment period. This process enabled us to use, for CY 2007, 68.5 million “pseudo” singles and 31.6 million “natural” single bills.

We proposed to bypass the 454 codes identified in Table 1 of the proposed rule (71 FR 49517) to create new single claims and to use the line-item costs associated with the bypass codes on these claims, together with the single procedure claims, in the creation of the median costs for the APCs into which they are assigned. Of the codes on this list, 404 codes were used for bypass in CY 2006. We proposed to continue the use of the codes on the CY 2006 OPPS bypass list and to expand it by adding codes that, using data presented to the APC Panel at its March 2006 meeting, meet the same empirical criteria as those used in CY 2006 to create the bypass list, or which our clinicians believe would contain minimal packaging if the services were correctly coded (for example, ultrasound guidance). (Bypass codes shown in Table 1 with an asterisk indicated the HCPCS codes we proposed to add to the CY 2006 OPPS listed codes for bypass in CY 2007.) Our examination of the data against the criteria for inclusion on the bypass list, as discussed below for the addition of new codes, shows that the empirically selected codes used for bypass for the CY 2006 OPPS generally continue to meet the criteria or come very close to meeting the criteria, and we have received no comments against bypassing them.

As proposed, the following empirical criteria that we used to determine the additional codes to add to the CY 2006 OPPS bypass list to create the bypass list for the CY 2007 OPPS were developed by reviewing the frequency and magnitude of packaging in the single claims for payable codes other than drugs and biologicals. We assumed that the representation of packaging on the single claims for any given code is comparable to packaging for that code in the multiple claims:

• There were 100 or more single claims for the code. This number of single claims ensured that observed outcomes were sufficiently representative of packaging that might occur in the multiple claims.

• Five percent or fewer of the single claims for the code had packaged costs on that single claim for the code. This criterion results in limiting the amount of packaging being redistributed to the payable procedure remaining on the claim after the bypass code is removed and ensures that the costs associated with the bypass code represent the cost of the bypassed service.

• The median cost of packaging observed in the single claims was equal to or less than $50. This limits the amount of error in redistributed costs.

• The code is not a code for an unlisted service.

In addition, we proposed to add to the bypass list codes that our clinicians believe contain minimal packaging and codes for specified drug administration services for which hospitals have requested separate payment but for which it is not possible to acquire median costs unless we add these codes to the bypass list. A more complete discussion of the effects of adding these drug administration codes to the bypass list is contained in the discussion of drug administration payment changes in section VIII.C. of this preamble.

In the CY 2007 OPPS proposed rule, we specifically invited public comment on the “pseudo” single process, including the bypass list and the criteria.

Comment:
The commenters urged CMS to continue to find ways to use all data from multiple procedure claims to set the median costs on which the payment rates are based. Many commenters supported the bypass list as a vehicle to enable use of all claims data. However, some commenters were concerned that placing HCPCS codes on the bypass list would lead to those codes being undervalued because no packaging from the multiple procedure bill is attributed to them. These commenters urged CMS to validate that these services were not being systematically undervalued by being bypassed and thus having many units of the service used for median setting with no attribution of packaging to the code. In many cases, the commenters did not offer specific discussion of what packaging they believe would be appropriately attached to the codes on the bypass list. One commenter suggested that CMS add CPT code 77421 (Steroscopic X-ray guidance for localization of target volume for the delivery of radiation therapy) to secure more single procedure claims data for median setting. Another commenter asked that CMS add CPT code 88307 (Level V-Surgical pathology, gross and microscopic examination) to the bypass list because it would be consistent with the inclusion of CPT codes 88304 (Level III-Surgical pathology, gross and microscopic examination) and 88305 (Level IV-Surgical pathology, gross and microscopic examination) on the bypass list.

Response:
We agree that the bypass list has been very useful in enabling us to use data from multiple procedure claims to set median costs for many services. The use of date of service stratification and the bypass list enabled us to create 68.5 million “pseudo” single claims that would not otherwise have been used to set median costs for the CY 2007 OPPS. However, we recognize that it is necessary to be cautious in this approach to minimize the possibility that we could mistakenly apply packaging on the claim to the wrong service. For that reason, each year we investigate the amount of packaging on natural single bills and consider whether changes should be made to the bypass list. However, in some cases, we know that the natural single bills are incorrect, and it is not

reasonable to base a decision on their level of packaging from what we believe are incorrectly coded claims. In these cases, we use clinical judgment to determine whether, on a correctly coded claim, the packaging would be associated with the code as defined or whether the packaging would more appropriately be associated with other procedures. For example, a single procedure bill for an ultrasound guidance service which is used only for guidance during an associated surgical procedure would not be correctly coded and therefore, clinically, we would not expect the packaged costs observed on these single claims to be correctly attributed to the guidance procedure. We believe that the ultrasound guidance procedure itself could not be the service that required the drugs, devices, or operating room use that would usually also be billed on a correctly coded claim. In these cases, we would place the ultrasound guidance procedure on the bypass list and attribute the packaged costs that appear on the same claim to the surgical procedure on the claim.

We have been actively investigating options for using all claims data in the establishment of median costs, and we intend to be ready to discuss our findings in the CY 2008 OPPS proposed rule. With respect to the suggestions for additions to the bypass list, we will evaluate the potential for adding CPT codes 77421 and 88307 to the bypass list for purposes of the CY 2008 OPPS ratesetting.

Comment:
One commenter asked that CMS use all claims data on multiple procedure claims by allocating the packaging on a claim with multiple surgical procedures based on the currently existing relative weights to create “pseudo” single claims from all multiple procedure claims. The commenter suggested that if CMS is concerned about that process causing the weights being calculated to not reflect changes in cost, CMS might use this process only in cases in which the number of units for HCPCS codes on natural single bills are below some tolerance so that these claims would be used only on low volume procedures.

Response:
We are concerned that use of the current relative weights to allocate the packaging on multiple procedure claims may cause packaging to be allocated inappropriately in some cases. As we indicate above, we are continuing to explore ways that packaging could be allocated on multiple procedure claims in such a way that we would have confidence in the allocation.

Comment:
One commenter requested that CMS remove CPT code 76942 (Ultrasonic guidance for needle placement (eg biopsy, aspiration, injection, localization device), imaging supervision and interpretation) from the bypass list, because the commenter believed it would raise the median cost for APC 0268, the APC where CPT code 76942 is assigned for CY 2007. According to the commenter, the natural single claims for CPT code 76942 have a higher median cost than the “pseudo” single claims. The commenter indicated that when all packaged costs are removed from the natural singles, their median is close to the median for the “pseudo” single claims. If removing this code from the bypass list altogether results in too few “pseudo” single claims, the commenter requested that CMS calculate the median cost for APC 0268 using only natural single claims.

Response:
We agree with the commenter that the median of APC 0268 is higher with the exclusion of “pseudo” singles that are created from claims that include CPT code 76942 than it would be if we only used true single claims that include CPT code 76942. However, we believe that the single bills for CPT code 76942 are miscoded and, therefore, inappropriately attribute the procedural costs (for example, the needle placement for biopsy and injection) to ultrasound guidance rather than the biopsy or aspiration procedures. We note that CPT code 76942 is the code with the highest frequency in APC 0268 and, therefore, contributes greatly to the median cost of the APC. The commenter provided no information regarding the specific packaging associated with CPT code 76942; therefore, we continue to believe that its inclusion on the bypass list, and the resulting calculation of the APC median cost for APC 0268, is appropriate.

After carefully considering all public comments received on our proposal, we are adopting as final the proposed “pseudo” single process and the bypass codes listed in Table 1.

c. Revised Overall Cost-to-Charge Ratio (CCR) Calculation

We calculate both an overall CCR and cost center-specific cost-to-charge ratios (CCRs) for each hospital. For the CY 2007 OPPS, we proposed to change the methodology for calculating the overall CCR. The overall CCR is used in many components of the OPPS. We use the overall CCR to estimate costs from charges on a claim when we do not have an accurate cost center CCR. This does not happen very often. For the vast majority of services, we are able to use a cost center CCR to estimate costs from charges. However, we also use the overall CCR to identify the outlier threshold, to model payments for services that are paid at charges reduced to cost, and, during implementation, to determine outlier payments and payments for other services.

As stated in the CY 2007 OPPS proposed rule (71 FR 49528), we have discovered that the calculation of the overall CCR that the fiscal intermediaries are using to determine outlier payments and payments for services paid at charges reduced to cost differs from the overall CCR that we use to model the OPPS. In Program Transmittal A-03-04 on “Calculating Provider-Specific Outpatient Cost-to-Charge Ratios (CCRs) and Instructions on Cost Report Treatment of Hospital Outpatient Services Paid on a Reasonable Cost Basis” (January 17, 2003), we revised the overall CCR calculation that the fiscal intermediaries use in determining outlier and other cost payments. Until this point, each fiscal intermediary had used an overall CCR provided by CMS, or calculated an updated CCR at the provider's request using the same calculation. The calculation in Program Transmittal A-03-04, that is, the fiscal intermediary calculation, diverged from the “traditional” overall CCR that we used for modeling. It should be noted that the fiscal intermediary overall CCR calculation noted in Program Transmittal A-03-04 was created with feedback and input from the fiscal intermediaries.

CMS' “traditional” calculation consists of summing the total costs from Worksheet B, Part I (Column 27), after removing the costs for nursing and paramedical education (Columns 21 and 24), for those ancillary cost centers that we believe contain most OPPS services, summing the total charges from Worksheet C, Part I (Columns 6 and 7) for the same set of ancillary cost centers, and dividing the former by the latter. We exclude selected ancillary cost centers from our overall CCR calculation, such as 5700 Renal Dialysis, because we believe that the costs and

charges in these cost centers are largely paid for under other payment systems. The specific list of ancillary cost centers, both standard and nonstandard, included in our overall CCR calculation is available on our Web site in the revenue center-to-cost center crosswalk workbook:
http://www.cms.hhs.gov/HospitalOutpatientPPS.

The overall CCR calculation provided in Program Transmittal A-03-04, on the other hand, takes the CCRs from Worksheet C, Part I, Column 9, for each specified ancillary cost center; multiplies them by the Medicare Part B outpatient specific charges in each corresponding ancillary cost center from Worksheet D, Part V (Columns 2, 3, 4, and 5 and subscripts thereof); and then divides the sum of these costs by the sum of charges for the specified ancillary cost centers from Worksheet D, Part V (Columns 2, 3, 4, and 5 and subscripts thereof). The elimination of the reference to Part VI in this final rule with comment period is not a change from the proposed methodology. We used only data from Worksheet D, Part V of the HCRIS electronic cost report to calculate the overall CCRs for both the proposed rule and final rule with comment period. We previously referenced both Part V and Part VI in the proposed rule and in prior rules because both Part V and Part VI appear on the same page in Worksheet D on the paper cost report, although no data from Part VI on the electronic cost report were used in the calculation.

Compared with our “traditional” overall CCR calculation that has been used for modeling OPPS and to calculate the median costs, this fiscal intermediary calculation of overall CCR fails to remove allied health costs and adds weighting by Medicare Part B charges.

In comparing these two calculations, we discovered that, on average, the overall CCR calculation being used by the fiscal intermediaries resulted in higher overall CCRs than under our “traditional” calculation. Using the most recent cost report data available for every provider with valid claims for CY 2004 as of November 2005, we estimated the median overall CCR using the traditional calculation to be 0.3040 (mean 0.3223) and the median overall CCR using the fiscal intermediary calculation to be 0.3309 (mean 0.3742). There also was much greater variability in the fiscal intermediary calculation of the overall CCR. The standard deviation under the “traditional” calculation was 0.1318, while the standard deviation using the fiscal intermediary's calculation was 0.2143. In part, the higher median estimate for the fiscal intermediary calculation is attributable to the inclusion of allied health costs for the over 700 hospitals with allied health programs. It is inappropriate to include these costs in the overall CCR calculation, because CMS already reimburses hospitals for the costs of these programs through cost report settlement. The higher median estimate and greater variability also is a function of the weighting by Medicare Part B charges. Because the fiscal intermediary overall CCR calculation is higher, on average, CMS has underestimated the outlier payment thresholds and, therefore, overpaid outlier payments. We also have underestimated spending for services paid at charges reduced to cost in our budget neutrality estimates.

In examining the two different calculations, we decided that elements of each methodology had merit. Clearly, as noted above, allied health costs should not be included in an overall CCR calculation. However, weighting by Medicare Part B charges from Worksheet D, Part V, makes the overall CCR calculation more specific to OPPS. Therefore, we proposed to adopt a single overall CCR calculation that incorporates weighting by Medicare Part B charges but excludes allied health costs for modeling and payment. Specifically, the proposed calculation removes allied health costs from cost center CCR calculations for specified ancillary cost centers, as discussed above, multiplies them by the Medicare Part B charges on Worksheet D, Part V, and sums these estimated Medicare costs. This sum is then divided by the sum of the same Medicare Part B charges for the same specified set of ancillary cost centers.

As we indicated in the proposed rule (71 FR 49528), using the same cost report data in this study, we estimated a median overall CCR for the proposed calculation of 0.3081 (mean 0.3389) with a standard deviation of 0.1583. The similarity to the median and standard deviation of the “traditional” overall CCR calculation noted above (median 0.3040 and standard deviation of 0.1318) masks some sizeable changes in overall CCR calculations for specific hospitals due largely to the inclusion of Medicare Part B weighting.

In order to isolate the overall impact of adopting this methodology on APC medians, we used the first 9 months of CY 2005 claims data to estimate APC median costs varying only the two methods of determining overall CCR. As stated in the CY 2007 OPPS proposed rule (71 FR 49528), we expected the impact to be limited because the majority of costs are estimated using a cost center-specific CCR and not the overall. As predicted, we observed minor changes in APC median costs from the adoption of the proposed overall CCR calculation. We largely observed differences of no more than 5 percent in either direction. The median overall percent change in APC cost estimates was −0.3 percent. We typically observe comparable changes in APC medians when we update our cost report data. Using updated cost report data for the calculations in this final rule with comment period, we estimate a median overall CCR across all hospitals of 0.3015 using the new overall CCR calculation.

We believe that a single overall CCR calculation should be used for all components of the OPPS for both modeling and payment. Therefore, we proposed to use the modified overall CCR calculation as discussed above when the hospital-specific overall CCR is used for any of the following calculations: in the CMS calculation of median costs for OPPS ratesetting, in the CMS calculation of the outlier threshold, in the fiscal intermediary calculation of outlier payments, in the CMS calculation of statewide CCRs, in the fiscal intermediary calculation of pass-through payments for devices, and for any other fiscal intermediary payment calculation in which the current hospital-specific overall CCR may be used now or in the future.

Comment:
Several commenters supported the proposed change to the calculation of the overall CCR to be weighted by Part B charges and to exclude the costs of nursing and allied health professional education programs. One commenter asked that CMS provide examples at the line level of how the revenue code to cost center crosswalk is applied to sample claims to illustrate to hospitals how selection of the revenue code for any particular item or service controls the resulting cost that is used in median calculation. The commenter also asked that CMS instruct fiscal intermediaries to allow hospitals to reclassify expense and revenue whenever the hospital believes it is appropriate, to ensure that the charges on the claim result in appropriate costs for median setting and order the fiscal intermediaries not to reverse reclassification of costs in audit adjustments. The commenter also suggested that CMS should have fiscal intermediaries conduct a survey of their audit staff with regard to the validity of the revenue code to cost center crosswalk.

Response:
We continue to believe that the proposed change to the CCR calculation is appropriate, and we have used the revised formula to calculate the

overall CCRs used to set the medians on which the CY 2007 payment rates are based.

With respect to the request for detailed examples to illustrate how selection of a revenue code will control the cost that is used in the median calculation, we believe that hospitals, like any business, are responsible for performing their own analysis regarding issues that affect their revenue stream. We have gone to great lengths in the preamble of our proposed and final rules to discuss how we derive costs from charges and how we crosswalk the charge from the revenue code reported for the charge to the cost center on the cost report. Moreover, the revenue code to cost center crosswalk has been on the CMS Web site for several years, open continuously to public comment. We do not believe it is necessary to create and publish examples at the claim-line level to further elaborate on how we convert charges to costs for purposes of establishing median costs. Hospitals that are interested should have sufficient information available already on this topic. Moreover, Medicare auditing rules have been well-established and standardized over many years, and we rely on our contractors to enforce them appropriately.

Comment:
One commenter suggested that CMS study the crosswalk that is used in the completion of the Provider Statistical and Reimbursement Report (PS&R) to determine whether changes to the CMS crosswalk of revenue codes to cost centers might be appropriate. Specifically, the commenter suggested the following revisions: Revenue code 0413 (hyperbaric oxygen therapy) should be crosswalked to the hospital overall CCR; Revenue code 026X (IV therapy) could have cost center 5600 (Drugs charges to patients) as the secondary default CCR before defaulting to the overall CCR; Revenue code 046X (Pulmondary therapy) should have cost center 4600 (respiratory therapy) as secondary and cost center 3160 as tertiary; and Revenue code 074X (EEG) should have cost center 5400 (EEG) as primary and cost center 3280 (EKG and EEG) as secondary.

Response:
We have not made any changes in response to the commenter's suggestions for CY 2007. However, we will carefully examine the commenter's suggestions with regard to the calculation of CCRs for the CY 2008 OPPS.

After carefully considering all the public comments received, we are adopting our proposal for CY 2007 without modification. As stated in the CY 2007 proposed rule (71 FR 49529), we will issue a Medicare program instruction to fiscal intermediaries that will instruct them to recalculate and use the hospital-specific overall CCR as we have finalized for the above stated purposes.

2. Calculation of Median Costs for CY 2007

In this section of the preamble, we discuss the use of claims to calculate the proposed OPPS payment rates for CY 2007. The hospital outpatient prospective payment page on the CMS Web site on which this final rule with comment period is posted provides an accounting of claims used in the development of the final rates:
http://www.cms.hhs.gov/HospitalOutpatientPPS.
The accounting of claims used in the development of this final rule with comment period is included on the Web site under supplemental materials for the CY 2007 final rule with comment period. That accounting provides additional detail regarding the number of claims derived at each stage of the process. In addition, below we discuss the files of claims that comprise the data sets that are available for purchase under a CMS data user contract. Our CMS Web site,
http://www.cms.hhs.gov/HospitalOutpatientPPS,
includes information about purchasing the following two OPPS data files: “OPPS Limited Data Set” and “OPPS Identifiable Data Set.”

As proposed, we used the following methodology to establish the relative weights to be used in calculating the OPPS payment rates for CY 2007 shown in Addenda A and B to this final rule with comment period. This methodology is as follows:

We used outpatient claims for the full CY 2005, processed before June 30, 2006, to set the relative weights for CY 2007. To begin the calculation of the relative weights for CY 2007, we pulled all claims for outpatient services furnished in CY 2005 from the national claims history file. This is not the population of claims paid under the OPPS, but all outpatient claims (including, for example, CAH claims, and hospital claims for clinical laboratory services for persons who are neither inpatients nor outpatients of the hospital).

We then excluded claims with condition codes 04, 20, 21, and 77. These are claims that providers submitted to Medicare knowing that no payment will be made. For example, providers submit claims with a condition code 21 to elicit an official denial notice from Medicare and document that a service is not covered. We then excluded claims for services furnished in Maryland, Guam, and the U.S. Virgin Islands, American Samoa, and the Northern Marianas because hospitals in those geographic areas are not paid under the OPPS.

We divided the remaining claims into the three groups shown below. Groups 2 and 3 comprise the 110 million claims that contain hospital bill types paid under the OPPS.

1. Claims that were not bill types 12X, 13X, 14X (hospital bill types), or 76X (CMHC bill types). Other bill types are not paid under the OPPS and, therefore, these claims were not used to set OPPS payment.

2. Claims that were bill types 12X, 13X, or 14X (hospital bill types). These claims are hospital outpatient claims.

3. Claims that were bill type 76X (CMHC). (These claims are later combined with any claims in item 2 above with a condition code 41 to set the per diem partial hospitalization rate determined through a separate process.)

For the CCR calculation process, we used the same general approach as we used in developing the final APC rates for CY 2006 (70 FR 68537), with a change to the development of the overall CCR as discussed above. That is, we first limited the population of cost reports to only those for hospitals that filed outpatient claims in CY 2005 before determining whether the CCRs for such hospitals were valid.

We then calculated the CCRs at a cost center level and overall for each hospital for which we had claims data. We did this using hospital-specific data from the Healthcare Cost Report Information System (HCRIS). We used the most recent available cost report data, in most cases, cost reports for CY 2004. As proposed, for this final rule with comment period, we used the most recently submitted cost report to calculate the CCRs to be used to calculate median costs for the CY 2007 OPPS. If the most recent available cost report was submitted but not settled, we looked at the last settled cost report to determine the ratio of submitted to settled cost using the overall CCR, and we then adjusted the most recent available submitted but not settled cost report using that ratio. We calculated both an overall CCR and cost center-specific CCRs for each hospital. We used the final overall CCR calculation discussed in II.A.1.c. of this preamble for all purposes that require use of an overall CCR.

We then flagged CAH claims, which are not paid under the OPPS, and claims from hospitals with invalid CCRs. The latter included claims from hospitals without a CCR; those from hospitals paid an all-inclusive rate; those from

hospitals with obviously erroneous CCRs (greater than 90 or less than .0001); and those from hospitals with CCRs that were identified as outliers (3 standard deviations from the geometric mean after removing error CCRs). In addition, we trimmed the CCRs at the cost center level by removing the CCRs for each cost center as outliers if they exceeded ±3 standard deviations from the geometric mean. This is the same methodology that we used in developing the final CY 2006 CCRs. For CY 2007, we proposed to trim at the departmental CCR level to eliminate aberrant CCRs that, if found in high volume hospitals, could skew the medians. We used a four-tiered hierarchy of cost center CCRs to match a cost center to every possible revenue code appearing in the outpatient claims, with the top tier being the most common cost center and the last tier being the default CCR. If a hospital's cost center CCR was deleted by trimming, we set the CCR for that cost center to “missing,” so that another cost center CCR in the revenue center hierarchy could apply. If no other departmental CCR could apply to the revenue code on the claim, we used the hospital's overall CCR for the revenue code in question. For example, if a visit was reported under the clinic revenue code, but the hospital did not have a clinic cost center, we mapped the hospital-specific overall CCR to the clinic revenue code. The hierarchy of CCRs is available for inspection and comment at the CMS Web site:
http://www.cms.hhs.gov/HospitalOutpatientPPS
.

We then converted the charges to costs on each claim by applying the CCR that we believed was best suited to the revenue code indicated on the line with the charge. Table 2 of the proposed rule (71 FR 49532) contained a list of the allowed revenue codes. Revenue codes not included in Table 2 are those not allowed under the OPPS because their services cannot be paid under the OPPS (for example, inpatient room and board charges) and thus, charges with those revenue codes were not packaged for creation of the OPPS median costs. One exception is the calculation of median blood costs, as discussed in section X. of this preamble.

Thus, we applied CCRs as described above to claims with bill types 12X, 13X, or 14X, excluding all claims from CAHs and hospitals in Maryland, Guam, and the U.S. Virgin Islands, American Samoa, and the Northern Marianas and claims from all hospitals for which CCRs were flagged as invalid.

We identified claims with condition code 41 as partial hospitalization services of hospitals and moved them to another file. These claims were combined with the 76X claims identified previously to calculate the partial hospitalization per diem rate.

We then excluded claims without a HCPCS code. We also moved claims for observation services to another file. We moved to another file claims that contained nothing but influenza and pneumococcal pneumonia (“PPV”) vaccine. Influenza and PPV vaccines are paid at reasonable cost and, therefore, these claims are not used to set OPPS rates. We note that the two above mentioned separate files containing partial hospitalization claims and observation services claims are included in the files that are available for purchase as discussed above.

We next copied line-item costs for drugs, blood, and devices (the lines stay on the claim, but are copied off onto another file) to a separate file. No claims were deleted when we copied these lines onto another file. These line-items are used to calculate a per unit mean and median and a per day mean and median for drugs, radiopharmaceutical agents, blood and blood products, and devices, including but not limited to brachytherapy sources, as well as other information used to set payment rates, including a unit to day ratio for drugs.

We then divided the remaining claims into the following five groups:

1.
Single Major Claims:
Claims with a single separately payable procedure (that is, status indicator S, T, V, or X), all of which would be used in median setting.

2.
Multiple Major Claims:
Claims with more than one separately payable procedure (that is, status indicator S, T, V, or X), or multiple units for one payable procedure. As discussed below, some of these can be used in median setting.

3.
Single Minor Claims:
Claims with a single HCPCS code that is packaged (that is, status indicator N) and not separately payable.

4.
Multiple Minor Claims:
Claims with multiple HCPCS codes that are packaged (that is, status indicator N) and not separately payable.

5.
Non-OPPS Claims:
Claims that contain no services payable under the OPPS (that is, all status indicators other than S, T, V, X, or N). These claims are excluded from the files used for the OPPS. Non-OPPS claims have codes paid under other fee schedules, for example, durable medical equipment or clinical laboratory, and do not contain either a code for a separately paid service or a code for a packaged service.

In previous years, we made a determination of whether each HCPCS code was a major code, or a minor code, or a code other than a major or minor code. We used those code-specific determinations to sort claims into these five identified groups. For the CY 2007 OPPS, we proposed to use status indicators, as described above, to sort the claims into these groups. We believed that using status indicators was an appropriate way to sort the claims into these groups and also to make our process more transparent to the public. We further believed that this proposed method of sorting claims would enhance the public's ability to derive useful information and become a more informed commenter on the proposed rule.

We note that the claims listed in numbers 1, 2, 3, and 4 above are included in the data files that can be purchased as described above.

We set aside the single minor, multiple minor claims and the non-OPPS claims (numbers 3, 4, and 5 above) because we did not use these claims in calculating median costs. We then examined the multiple major claims for date of service to determine if we could break them into single procedure claims using the dates of service on all lines on the claim. If we could create claims with single major procedures by using date of service, we created a single procedure claim record for each separately paid procedure on a different date of service (that is, a “pseudo” single).

We then used the “bypass codes” listed in Table 1 of the proposed rule (71 FR 49517) and discussed in section II.A.1.b. of this preamble to remove separately payable procedures that we determined contain limited costs or no packaged costs, or were otherwise suitable for inclusion on the bypass list, from a multiple procedure bill. When one of the two separately payable procedures on a multiple procedure claim was on the bypass code list, we split the claim into two single procedure claims records. The single procedure claim record that contained the bypass code did not retain packaged services. The single procedure claim record that contained the other separately payable procedure (but no bypass code) retained the packaged revenue code charges and the packaged HCPCS charges.

We also removed lines that contained multiple units of codes on the bypass list and treated them as “pseudo” single claims by dividing the cost for the multiple units by the number of units on the line. Where one unit of a single separately paid procedure code remained on the claim after removal of the multiple units of the bypass code, we created a “pseudo” single claim

from that residual claim record, which retained the costs of packaged revenue codes and packaged HCPCS codes. This enabled us to use claims that would otherwise be multiple procedure claims and could not be used. We excluded those claims that we were not able to convert to singles even after applying all of the techniques for creation of “pseudo” singles.

We then packaged the costs of packaged HCPCS codes (codes with status indicator “N” listed in Addendum B to this proposed rule) and packaged revenue codes into the cost of the single major procedure remaining on the claim. The list of packaged revenue codes was shown in Table 2 of the CY 2007 OPPS proposed rule (71 FR 49532) and below.

After removing claims for hospitals with error CCRs, claims without HCPCS codes, claims for immunizations not covered under the OPPS, and claims for services not paid under the OPPS, 58.4 million claims were left. Of these 58.4 million claims, we were able to use some portion of 54.1 million whole claims (92.6 percent of the 58.4 million potentially usable claims) to create the 98.5 million single and “pseudo” single claims for use in the CY 2007 median development and for ratesetting.

We also excluded (1) claims that had zero costs after summing all costs on the claim and (2) claims containing packaging flag 3. Effective for services furnished on or after July 1, 2004, the Outpatient Code Editor (OCE) assigns packaging flag number 3 to claims on which hospitals submitted token charges for a service with status indicator “S” or “T” (a major separately paid service under OPPS) for which the fiscal intermediary is required to allocate the sum of charges for services with a status indicator equaling “S” or “T” based on the weight for the APC to which each code is assigned. We do not believe that these charges, which were token charges as submitted by the hospital, are valid reflections of hospital resources. Therefore, we deleted these claims. In the proposed rule, we deleted claims with payment flag 3 (not packaging flag 3) because we believed that payment flag 3 identified claims for which the charges were not as submitted by the provider as described above. As we were processing claims for this final rule with comment period, we realized that this was not the case and corrected the process to eliminate claims which, as described above, have charges that are not as submitted by the provider. See the CY 2007 final rule claims accounting under supporting documentation posted on our Web site,
http://www.cms.hhs.gov/HospitalOutpatientPPS
, for this final rule with comment period for further explanation. We note that in this final rule with comment period, as stated in both the proposed rule and here, we have excluded those claims that we believed were not valid reflections of hospital resources.

We also deleted claims for which the charges equal the revenue center payment (that is, the Medicare payment) on the assumption that where the charge equals the payment, to apply a CCR to the charge would not yield a valid estimate of relative provider cost.

For the remaining claims, we then standardized 60 percent of the costs of the claim (which we have previously determined to be the labor-related portion) for geographic differences in labor input costs. We made this adjustment by determining the wage index that applied to the hospital that furnished the service and dividing the cost for the separately paid HCPCS code furnished by the hospital by that wage index. As has been our policy since the inception of the OPPS, we proposed to use the pre-reclassified wage indices for standardization because we believed that they better reflect the true costs of items and services in the area in which the hospital is located than the post-reclassification wage indices, and would result in the most accurate adjusted median costs.

We also excluded claims that were outside 3 standard deviations from the geometric mean of units for each HCPCS code on the bypass list (because, as discussed above, we used claims that contain multiple units of the bypass codes). We then deleted 438,440 single bills reported with modifier 50 that were assigned to APCs that contained HCPCS codes that are considered to be conditional or independent bilateral procedures under the OPPS and that are subject to special payment provisions implemented through the OCE. Modifier 50 signifies that the procedure was performed bilaterally. Although these are apparently single claims for a separately payable service and although there is only one unit of the code reported on the claim, the presence of modifier 50 signifies that two services were furnished. Therefore, costs reported on these claims are for two procedures and not for a single procedure. Hence, we deleted these multiple procedure records, which we would have treated as single procedure claims in prior OPPS updates.

We used the remaining claims to calculate median costs for each separately payable HCPCS code and each APC. The comparison of HCPCS and APC medians determines the applicability of the “2 times” rule. As stated previously, section 1833(t)(2) of the Act provides that, subject to certain exceptions, the items and services within an APC group cannot be considered comparable with respect to the use of resources if the highest median (or mean cost, if elected by the Secretary) for an item or service in the group is more than 2 times greater than the lowest median cost for an item or service within the same group (“the 2 times rule”). Finally, we reviewed the medians and reassigned HCPCS codes to different APCs as deemed appropriate. Section III.B. of this preamble includes a discussion of the HCPCS code assignment changes that resulted from examination of the medians and for other reasons. The APC medians were recalculated after we reassigned the affected HCPCS codes. Both the HCPCS medians and the APC medians were weighted to account for the inclusion of multiple units of the bypass codes in the creation of pseudo single bills.

A detailed discussion of the medians for blood and blood products is included in section X. of this preamble. A discussion of the medians for APCs that require one or more devices when the service is performed is included in section IV.A. of this preamble. A discussion of the median for observation services is included in section XI. of this preamble, and a discussion of the median for partial hospitalization is included below in section II.B. of this preamble.

We specifically invited public comment on the relative benefits of deleting claims reported with modifier 50 signifying two procedures were performed versus dividing the costs for the two procedures by two to create two “pseudo” single claims. We received one comment on this issue.

Comment:
One commenter supported deletion of the conditional or independent bilateral service claims because the commenter believes that the total cost of a bilateral procedure (including packaged costs) is generally less than 2 times the total cost of a unilateral procedure, and such cost savings are already reflected in each hospital's CCR. The commenter stated that to divide the cost of the bilateral procedure by two would result in “pseudo” singles that would underrepresent the full cost of a single procedure.

Response:
We have excluded claims for conditional and independent bilateral procedures from the claims we used to calculate the median costs for the CY 2007 OPPS. We will carefully consider how to treat these claims for future years.

For the final CY 2007 OPPS ratesetting process, we deleted these claims, as we did for the proposed rule.

We received many comments on our proposed CY OPPS data process. A summary of the comments and our responses follows:

Comment:
The commenters objected to what they view as wide fluctuations in the APC payment rates from CY 2006 to CY 2007, because such variability makes it difficult to plan and budget for the services that the hospital will provide in the upcoming year. The commenters objected to changes in proposed OPPS rates that are greater than 5 percent from the prior year's rates and urged CMS to adjust rates so that no payment rate in CY 2007 declined by more than 5 percent compared to its payment in CY 2006. The commenters stated that more than 250 APC rates declined compared to their CY 2006 rates, some by 10 to 20 percent or more. In contrast, they noted that over 300 APC rates increased, many substantially and by up to 30 percent compared to their CY 2006 rates. The commenters stated that they did not believe that the changes in the median costs were reflective of changes in hospital costs, because hospital costs do not vary so widely from year to year. The commenters indicated that they expected that after more than 5 years of experience, the rates would no longer show such significant volatility and urged CMS to use more multiple claims data to set the median costs.

Response:
There are a number of factors pertinent to the OPPS that cause median costs to change from one year to the next. These include reassignment of HCPCS codes to APCs to rectify 2 times violations and to respond to public comments; the need to split costs derived from claims data among the many different HCPCS codes, which results in very few usable claims for some services; and annual changes in reported hospital charges and costs that provide the source of the cost data on which the system is based.

Although the APC number and title may remain the same from year to year, we routinely reassign HCPCS codes to different APCs to resolve violations of the 2 times rule as required by law or reconfigure APCs to create more levels in a series. We also reassign codes in response to public comments when we believe that the requested reassignment will result in improved clinical homogeneity and more similar resource use for a particular service or group of services. To the extent that there has been a reassignment either into or out of an APC or a reconfiguration of an APC into multiple levels, a comparison of the APC median from 1 year to the next is often not a valid comparison of the costs for the same services. In addition, every year new HCPCS codes that were initially assigned to clinical APCs for payment purposes may begin to contribute claims data to those APC median costs, also leading to ill-founded comparisons across years.

Moreover, many of the claims we receive for OPPS services are multiple procedure claims that must be fragmented for use in establishing the median costs for single procedures. Unlike other prospective payment systems in which the costs of multiple services are aggregated into a single payment for a defined encounter (for example, inpatient stay and home health episode of care), under the OPPS the costs that reflect the charges on Medicare claims that contain more than a single service on the same date must be fragmented into pieces to provide costs at a unit level, rather than being aggregated to provide the total cost for a set of services furnished in a single encounter. The more the costs on claims are split to accommodate payment for individual items and services described by HCPCS codes, and the fewer single bills that are available for ratesetting because the costs cannot be fragmented into unique services, the more variability is introduced into the cost. Because of the difficulty in assigning the revenue code charge data that hospitals submit on multiple procedure claims to the separately payable HCPCS codes that form the basis of payment in the OPPS, we must often use small numbers of claims to set the median costs for some services. We believe that the small numbers of single claims are the source of much of the volatility in the payment system. When we examine claims data for APCs like the Visit APCs, for which we have large and stable numbers of services, we do not see the median cost fluctuations that typically occur in those APCs for which we regularly have small numbers of single bills.

However, we are rarely asked for larger APCs that contain more codes or for more packaging of payment for HCPCS codes into the APC rates, both of which would enable us to use more claims and, we believe, provide more stable payment rates. Indeed, payment in the OPPS has become more specific each year, largely in response to our willingness to accommodate the requests of stakeholders when we believe they are justified and supported by the data. Each year, we are asked for increasingly more APCs that contain fewer HCPCS codes, as well as more precise costing of particular services. Generally, the comments received in response to our proposed rule asked for more separate payment, less packaging, and greater service-specific precision in the calculation of median costs for specifically identified services in the OPPS. We are also often asked to specifically recalculate median costs by using subsets of claims that meet specific criteria or by applying alternative methodologies for identified services. While these special approaches are generally intended to increase payments for their particular services of interest, they likely contribute to less stability in the system in general. Inevitably, such specificity would lead to more, not less, volatility as it would reduce the number of claims that can be used to set median costs.

Lastly, hospital charges and costs are the foundation of the payment weights, but hospitals change the mix of services they furnish and thereby also change their cost structure to some extent each year. Moreover, hospitals increase, sometimes decrease, or hold steady their charges each year based on a variety of business reasons, but these changes to charges often vary across the different services they furnish. Thus, hospital decisions to change their mix of services or to change their charges for some services differentially also contribute to the volatility in payment rates.

We recognize that it could be desirable for a payment system's rates to not vary by a certain percentage from the prior year's payment rates, but there is no reason to believe that limiting the changes in payment rates to prevent a decline by any percentage each year would be accurately reflective of changes in relative costs. Although the commenters asked that no payment for any service decline by more than 5 percent, none addressed a limitation for a payment increase. We do not believe that it is appropriate to artificially impose limits on a payment rate's increase or decrease from one year to the next, because, as noted above, comparisons between APC payment rates from year to year have little meaning for the many APCs that have experienced HCPCS migration. Moreover, to limit the increases or decreases in payment to a set amount for all services would conflict with the statutory requirement that at least annually we revise APCs and other components of the OPPS using new cost data and other relevant information. Therefore, we are not adjusting the rates as requested to account for a decline of more than 5 percent from CY 2006 in the final CY 2007 OPPS payment rates. We will continue to explore ways to use the data from multiple procedure claims because we a
