URL: https://www.frixlaw.com/law-library/documents/fr%3A06-4240 ## Record - **Collection:** Federal Register - **Document type:** Rule - **Published:** May 12, 2006 - **Citation:** 71 FR 27798 ## Text DEPARTMENT OF HEALTH AND HUMAN SERVICES Centers for Medicare & Medicaid Services 42 CFR Part 412 [CMS-1485-F] RIN 0938-AO06 Medicare Program; Prospective Payment System for Long-Term Care Hospitals RY 2007: Annual Payment Rate Updates, Policy Changes, and Clarification AGENCY: Centers for Medicare & Medicaid Services (CMS), HHS. ACTION: Final Rule. SUMMARY: This final rule updates the annual payment rates for the Medicare prospective payment system (PPS) for inpatient hospital services provided by long-term care hospitals (LTCHs). The payment amounts and factors used to determine the updated Federal rates that are described in this final rule have been determined for the LTCH PPS rate year July 1, 2006 through June 30, 2007. The annual update of the long-term care diagnosis-related group (LTC-DRG) classifications and relative weights remains linked to the annual adjustments of the acute care hospital inpatient diagnosis-related group system, and will continue to be effective each October 1. The outlier threshold for July 1, 2006, through June 30, 2007, is also derived from the LTCH PPS rate year calculations. We are also finalizing policy changes and making clarifications. DATES: This final rule is effective July 1, 2006. FOR FURTHER INFORMATION CONTACT: Tzvi Hefter, (410) 786-4487 (General information).

Legislative and Regulatory Authority Section 123 of the Medicare, Medicaid, and SCHIP [State Children's Health Insurance Program] Balanced Budget Refinement Act of 1999 (BBRA) (Pub. L. 106-113) as amended by section 307(b) of the Medicare, Medicaid, and SCHIP Benefits Improvement and Protection Act of 2000 (BIPA) (Pub. L. 106-554) provides for payment for both the operating and capital-related costs of hospital inpatient stays in long-term care hospitals (LTCHs) under Medicare Part A based on prospectively set rates. The Medicare prospective payment system (PPS) for LTCHs applies to hospitals described in section 1886(d)(1)(B)(iv) of the Social Security Act (the Act), effective for cost reporting periods beginning on or after October 1, 2002. Section 1886(d)(1)(B)(iv)(I) of the Act defines a LTCH as “a hospital which has an average inpatient length of stay (as determined by the Secretary) of greater than 25 days.” Section 1886(d)(1)(B)(iv)(II) of the Act also provides an alternative definition of LTCHs: Specifically, a hospital that first received payment under section 1886(d) of the Act in 1986 and has an average inpatient length of stay (LOS) (as determined by the Secretary of Health and Human Services (the Secretary)) of greater than 20 days and has 80 percent or more of its annual Medicare inpatient discharges with a principal diagnosis that reflects a finding of neoplastic disease in the 12-month cost reporting period ending in FY 1997. Section 123 of the BBRA requires the PPS for LTCHs to be a per discharge system with a diagnosis-related group (DRG) based patient classification system that reflects the differences in patient resources and costs in LTCHs while maintaining budget neutrality. Section 307(b)(1) of the BIPA, among other things, mandates that the Secretary shall examine, and may provide for, adjustments to payments under the LTCH PPS, including adjustments to DRG weights, area wage adjustments, geographic reclassification, outliers, updates, and a disproportionate share adjustment. In a Federal Register document issued on August 30, 2002, we implemented the LTCH PPS authorized under BBRA and BIPA (67 FR 55954). This system uses information from LTCH patient records to classify patients into distinct long-term care diagnosis-related groups (LTC-DRGs) based on clinical characteristics and expected resource needs. Payments are calculated for each LTC-DRG and provisions are made for appropriate payment adjustments. Payment rates under the LTCH PPS are updated annually and published in the Federal Register . The LTCH PPS replaced the reasonable cost-based payment system under the Tax Equity and Fiscal Responsibility Act of 1982 (TEFRA) (Pub. L. 97-248) for payments for inpatient services provided by a LTCH with a cost reporting period beginning on or after October 1, 2002. (The regulations implementing the TEFRA reasonable cost-based payment provisions are located at 42 CFR part 413.) With the implementation of the PPS for acute care hospitals authorized by the Social Security Amendments of 1983 (Pub. L. 98-21), which added section 1886(d) to the Act, certain hospitals, including LTCHs, were excluded from the PPS for acute care hospitals and were paid their reasonable costs for inpatient services subject to a per discharge limitation or target amount under the TEFRA system. Generally, for each cost reporting period, a hospital-specific ceiling on payments was determined by multiplying the hospital's updated target amount by the number of total current year Medicare discharges. The August 30, 2002 final rule further details the payment policy under the TEFRA system (67 FR 55954). In the August 30, 2002 final rule, we also presented an in-depth discussion of the LTCH PPS, including the patient classification system, relative weights, payment rates, additional payments, and the budget neutrality requirements mandated by section 123 of the BBRA. The same final rule that established regulations for the LTCH PPS under part 412, subpart O, also contained LTCH provisions related to covered inpatient services, limitation on charges to beneficiaries, medical review requirements, furnishing of inpatient hospital services directly or under arrangement, and reporting and recordkeeping requirements. We refer readers to the August 30, 2002 final rule for a comprehensive discussion of the research and data that supported the establishment of the LTCH PPS (67 FR 55954). On June 6, 2003, we published a final rule in the Federal Register (68 FR 34122) that set forth the FY 2004 annual update of the payment rates for the Medicare PPS for inpatient hospital services furnished by LTCHs. It also changed the annual period for which the payment rates are effective. The annual updated rates are now effective from July 1 through June 30 instead of from October 1 through September 30. We refer to the July through June time period as a “long-term care hospital rate year” (LTCH PPS rate year). In addition, we changed the publication schedule for the annual update to allow for an effective date of July 1. The payment amounts and factors used to determine the annual update of the LTCH PPS Federal rate is based on a LTCH PPS rate year. While the LTCH payment rate update is effective July 1, the annual update of the LTC-DRG classifications and relative weights are linked to the annual adjustments of the acute care hospital inpatient DRGs and are effective each October 1. On May 6, 2005, we published the Prospective Payment System for Long-Term Care Hospitals: Annual Payment Rate Updates, Policy Changes, and Clarifications final rule (70 FR 24168) (hereinafter referred to as the RY 2006 LTCH PPS final rule). In this rule, we set forth the 2006 LTCH PPS rate year annual update of the payment rates for the Medicare PPS for inpatient hospital services provided by LTCHs. We also discussed clarification of the notification policy for co-located LTCHs and satellite facilities. The RY 2006 LTCH PPS final rule also included a provision to extend the surgical DRG exception in the 3-day or less interruption of stay policy at § 412.531, as well as a provision that clarified and modified existing notification requirements for the purpose of implementing § 412.532. B. Criteria for Classification as a LTCH 1. Classification as a LTCH Under the existing regulations at § 412.23(e)(1) and (e)(2)(i), which implement section 1886(d)(1)(B)(iv)(I) of the Act, to qualify to be paid under the LTCH PPS, a hospital must have a provider agreement with Medicare and must have an average Medicare inpatient LOS of greater than 25 days. Alternatively, § 412.23(e)(2)(ii) states that for cost reporting periods beginning on or after August 5, 1997, a hospital that was first excluded from the PPS in 1986 and can demonstrate that at least 80 percent of its annual Medicare inpatient discharges in the 12-month cost reporting period ending in FY 1997 have a principal diagnosis that reflects a finding of neoplastic disease, must have an average inpatient LOS for all patients, including both Medicare and non-Medicare inpatients, of greater than 20 days. Section 412.23(e)(3) provides that, subject to the provisions of paragraphs (e)(3)(ii) through (e)(3)(iv) of this section, the average Medicare inpatient LOS, specified under § 412.23(e)(2)(i) is calculated by dividing the total number of covered and noncovered days of stay of Medicare inpatients (less leave or pass days) by the number of total Medicare discharges for the hospital's most recent complete cost reporting period. Section 412.23 also provides that subject to the provisions of paragraphs (e)(3)(ii) through (e)(3)(iv) of this section, the average inpatient LOS specified under § 412.23(e)(2)(ii) is calculated by dividing the total number of days for all patients, including both Medicare and non-Medicare inpatients (less leave or pass days) by the number of total discharges for the hospital's most recent complete cost reporting period. In the RY 2005 LTCH PPS final rule (69 FR 25674), we specified the procedure for calculating a hospital's inpatient average length of stay (ALOS) for purposes of classification as a LTCH. That is, if a patient's stay includes days of care furnished during two or more separate consecutive cost reporting periods, the total days of a patient's stay would be reported in the cost reporting period during which the patient is discharged (69 FR 25705). Therefore, we revised the regulations at § 412.23(e)(3)(ii) to specify that, effective for cost reporting periods beginning on or after July 1, 2004, in calculating a hospital's ALOS, if the days of an inpatient stay involve days of care furnished during two or more separate consecutive cost reporting periods, the total number of days of the stay are considered to have occurred in the cost reporting period during which the inpatient was discharged. Fiscal intermediaries (FIs) verify that LTCHs meet the ALOS requirements. We note that the inpatient days of a patient who is admitted to a LTCH without any remaining Medicare days of coverage, regardless of the fact that the patient is a Medicare beneficiary, will not be included in the above calculation. Because Medicare would not be paying for any of the patient's treatment, data on the patient's stay would not be included in the Medicare claims processing systems. As described in § 409.61, in order for both covered and noncovered days of a LTCH hospitalization to be included, a patient admitted to the LTCH must have at least one remaining benefit day (68 FR 34123). The FI's determination of whether or not a hospital qualified as a LTCH is based on the hospital's discharge data from the hospital's most recent complete cost reporting period (§ 412.23(e)(3)) and is effective at the start of the hospital's next cost reporting period (§ 412.22(d)). However, if the hospital does not meet the ALOS requirement as specified in § 412.23(e)(2)(i) and (ii), the hospital may provide the intermediary with data indicating a change in the ALOS by the same method for the period of at least 5 months of the immediately preceding 6-month period (69 FR 25676). Our interpretation of the current regulations at § 412.23(e)(3) was to allow hospitals to submit data using a period of at least 5 months of the most recent data from the immediately preceding 6-month period. As we stated in the FY 2004 Inpatient Prospective Payment System (IPPS) final rule, published August 1, 2003, prior to the implementation of the LTCH PPS, we did rely on data from the most recently submitted cost report for purposes of calculating the ALOS (68 FR 45464). The calculation to determine whether an acute care hospital qualifies for LTCH status was based on total days and discharges for LTCH inpatients. However, with the implementation of the LTCH PPS, for the ALOS specified under § 412.23(e)(2)(i), we revised § 412.23(e)(3)(i) to only count total days and discharges for Medicare inpatients (67 FR 55970 through 55974). In addition, the ALOS specified under § 412.23(e)(2)(ii) is calculated by dividing the total number of days for all patients, including both Medicare and non-Medicare inpatients (less leave or pass days) by the number of total discharges for the hospital's most recent complete cost reporting period. As we discussed in the FY 2004 IPPS final rule, we are unable to capture the necessary data from our present cost reporting forms (68 FR 45464). Therefore, we have notified FIs and LTCHs that until the cost reporting forms are revised, for purposes of calculating the ALOS, we will be relying upon census data extracted from Medicare Provider Analysis and Review (MedPAR) files that reflect each LTCH's cost reporting period (68 FR 45464). Requirements for hospitals seeking classification as LTCHs that have undergone a change in ownership, as described in § 489.18, are set forth in § 412.23(e)(3)(iv). 2. Hospitals Excluded from the LTCH PPS The following hospitals are paid under special payment provisions, as described in § 412.22(c) and, therefore, are not subject to the LTCH PPS rules: • Veterans Administration hospitals. • Hospitals that are reimbursed under State cost control systems approved under 42 CFR part 403. • Hospitals that are reimbursed in accordance with demonstration projects authorized under section 402(a) of the Social Security Amendments of 1967 (Pub. L. 90-248) (42 U.S.C. 1395b-1) or section 222(a) of the Social Security Amendments of 1972 (Pub. L. 92-603) (42 U.S.C. 1395b-1 (note)) (Statewide all-payer systems, subject to the rate-of-increase test at section 1814(b) of the Act). • Nonparticipating hospitals furnishing emergency services to Medicare beneficiaries. C. Transition Period for Implementation of the LTCH PPS In the August 30, 2002 final rule, we provided for a 5-year transition period from reasonable cost-based reimbursement to a full Federal prospective payment based on 100 percent of the Federal rate for LTCHs (67 FR 56038). However, existing LTCHs and LTCHs that are not defined as new in § 412.533(d) have the option to elect to be paid based on 100 percent of the Federal prospective payment. During the 5-year period, two payment percentages are to be used to determine a LTCH's total payment under the PPS. The blend percentages are as shown in Table 1. Table 1 Cost reporting periods beginning on or after Prospective payment federal rate percentage Reasonable cost-based reimbursement rate percentage October 1, 2002 20 80 October 1, 2003 40 60 October 1, 2004 60 40 October 1, 2005 80 20 October 1, 2006 100 0 D. Limitation on Charges to Beneficiaries In the August 30, 2002 final rule, we presented an in-depth discussion of beneficiary liability under the LTCH PPS (67 FR 55974 through 55975). In the RY 2005 LTCH PPS final rule (69 FR 25676), we clarified that the discussion of beneficiary liability in the August 30, 2002 final rule was not meant to establish rates or payments for, or define Medicare-eligible expenses. Under § 412.507, as consistent with other established hospital prospective payment systems, a LTCH may not bill a Medicare beneficiary for more than the deductible and coinsurance amounts as specified under § 409.82, § 409.83, and § 409.87 and for items and services as specified under § 489.30(a) if the Medicare payment to the LTCH is the full LTC-DRG payment amount. However, under the LTCH PPS, Medicare will only pay for days for which the beneficiary has coverage until the short-stay outlier (SSO) threshold is exceeded. (See section V.A.1.a. of this preamble.) Therefore, if the Medicare payment was for a SSO case (§ 412.529) that was less than the full LTC-DRG payment amount because the beneficiary had insufficient remaining Medicare days, the LTCH could also charge the beneficiary for services delivered on those uncovered days (§ 412.507). E. Administrative Simplification Compliance Act (ASCA) and Health Insurance Portability and Accountability Act (HIPAA) Compliance Claims submitted to Medicare must comply with both the Administrative Simplification Compliance Act (ASCA) (Pub. L. 107-105), and Health Insurance Portability and Accountability Act (HIPAA) (Pub. L. 104-191). Section 3 of the ASCA requires that the Medicare Program deny payment under Part A or Part B for any expenses for items or services “for which a claim is submitted other than in an electronic form specified by the Secretary.” Section 1862(h) of the Act (as added by section 3(a) of the ASCA) provides that the Secretary shall waive such denial in two types of cases and may also waive such denial “in such unusual cases as the Secretary finds appropriate.” (Also, see 68 FR 48805, August 15, 2003, implementing section 3 of the ASCA.) Section 3 of the ASCA operates in the context of the Administrative Simplification provisions of HIPAA, which include, among other provisions, the transactions and code sets standards requirements codified as 45 CFR parts 160 and 162, subparts A and I through R (generally known as the Transactions Rule). The Transactions Rule requires covered entities, including covered providers, to conduct covered electronic transactions according to the applicable transactions and code sets standards. II. Publication of Proposed Rulemaking On January 27, 2006, we published the RY 2007 LTCH PPS proposed rule in the Federal Register (71 FR 4648 through 4779) that set forth the proposed annual update to the payments for the Medicare prospective payment system (PPS) for inpatient hospital services provided by long-term care hospitals (LTCHs) for the 2007 LTCH PPS rate year. (The annual update of the LTC-DRG classifications and relative weights for FY 2007 remains linked to the annual adjustments of the acute care hospital inpatient DRG system, which will be published by August 1, 2006 and will be effective October 1, 2006. In the RY 2007 LTCH PPS proposed rule (71 FR 4648 through 4779), we discussed the proposed annual update to the payment rates for the Medicare LTCH PPS, as well as other proposed policy changes. The following is a summary of the major areas that we addressed in the proposed rule. In the proposed rule, we discussed the LTCH PPS patient classification and the relative weights which remain linked to the annual adjustments of the acute care hospital inpatient DRG system, and are based on the annual revisions to the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes effective each October 1. (See section IV. of this preamble.) In addition, we proposed to adopt the “Rehabilitation, Psychiatric, Long-Term Care (RPL)” market basket under the LTCH PPS in place of the excluded hospital with capital market basket. (See section V.B. of this preamble.) We also proposed a zero percent update to the LTCH PPS Federal rate for the 2007 LTCH PPS rate year instead of the most recent estimate of the LTCH PPS market basket. (See section V.C. of this preamble.) In that same proposed rule, we discussed the proposed prospective payment rate for RY 2007, and the applicable adjustments to the proposed payment rates, including the proposed revisions to the wage index, the proposed cost-of-living adjustment factors, the proposed outlier threshold, and the proposed transition period budget neutrality factor for the 2007 LTCH PPS rate year. We also proposed revisions to the cost-to-charge ratio and reconciliation provisions as they apply to LTCH outlier payment policies. (See section V.C. and V.D. of this preamble.) In addition, we discussed our proposal to revise the LTCH PPS labor-related share based on RPL market basket and our proposal to revise the labor-related and non-labor related shares of the Federal rate based on the RPL market basket. We also proposed to postpone the deadline for making the one-time prospective adjustment for the Federal rate at § 412.523(d)(3). (See section V.D. of this preamble.) Also, we proposed to revise the existing payment adjustment for SSO cases by reducing the part of the current payment formula that is based on costs and adding a fourth component to the current payment formula. We also proposed to sunset the surgical DRG exception to the payment policy established under the 3-day or less interruption of stay regulations at § 412.531(a)(1). (See section VI.A. of this preamble.) For LTCH hospitals within hospitals (HwHs) and LTCH satellites, we proposed to clarify at § 412.534(c) that under the policy for adjusting the LTCH PPS payment based on the amount that would be determined under the IPPS payment methodology, we will calculate the LTCH PPS payment amount that is equivalent to what would otherwise be paid under the IPPS. We also proposed to codify in regulations the general formula we currently use to give affect to the regulations as they pertain to calculating an amount under subpart O that is equivalent to an amount that would be determined under § 412.1(a). (See section VI.B. of this preamble.) In the same proposed rule, we discussed our on-going monitoring protocols under the LTCH PPS. (See section XI. of this preamble.) In addition, we discussed the recommendations made by the Research Triangle Institute, International's (RTI) evaluation of the feasibility of adopting recommendations made in the June 2004 MedPAC Report. (See section XII. of this preamble.) We also analyzed the impact of the proposed changes presented in the proposed rule on Medicare expenditures, Medicare-participating LTCHs, and Medicare beneficiaries. (See section XIV. of this preamble.) In Appendix A of the proposed rule, we presented a description of a preliminary model of an update framework under the LTCH PPS that we may propose to use in the future for purposes of the annual updating of the LTCH PPS Federal rate in future years. We received a total of 860 timely comments on the proposed rule. The major issues addressed by the commenters included: The proposed update framework; the proposed RPL framework; the proposed update to the Federal rate for RY 2007; the proposed high cost outlier (HCO) threshold for RY 2007; the proposed revision to the cost-to-charge ratios and reconciliation provisions as they apply to LTCH outlier payment policies; the proposed sunsetting of the surgical-DRG exception to the 3-day or less interruption of stay policy; the proposed SSO policy; the proposed postponement of the one-time prospective adjustment to the standard Federal rate; the proposed clarification of the present policy for adjusting the LTCH PPS payment for LTCH HwHs and LTCH satellites; and discussion of the recommendations made by RTI. Summaries of the public comments received and our responses to those comments are described below under the appropriate heading. III. Summary of the Major Contents of This Final Rule In this final rule, we are setting forth the annual update to the payment rates for the Medicare LTCH PPS, as well as finalizing other policy changes. The following is a summary of the major areas that we are addressing in this final rule. A. Update Changes In section IV of this preamble, we discuss the LTCH PPS patient classification and the relative weights which remain linked to the annual adjustments of the acute care hospital inpatient DRG system, which are based on the annual revisions to the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes effective each October 1. In section V. through XII. of this preamble, we specify the factors and adjustments used to determine the LTCH PPS rates that are applicable to the 2007 LTCH PPS rate year, including revisions to the wage index, the applicable adjustments to payments, cost-of-living adjustment factors, the outlier threshold, the budget neutrality factor, MedPAC recommendations and monitoring. In section V.B. of this preamble, we are adopting the “Rehabilitation, Psychiatric, Long-Term Care (RPL)” market basket under the LTCH PPS in place of the excluded hospital with capital market basket. We are also revising the labor-related share (and non-labor related share) of the Federal rate based on the RPL market basket. (See section V.D.1.c. of this preamble). As discussed in section V.C. of this preamble, we are implementing a zero percent update to the LTCH PPS Federal rate for the 2007 LTCH PPS rate year based on an adjustment to the most recent estimate of the LTCH PPS market basket to account for apparent case-mix increase. While we proposed to revise the cost-to-charge ratio and reconciliation provisions as they apply to LTCH outlier payment policies, we are not making these changes in this final rule; rather, in response to comments, we are again proposing these policies in the FY 2007 IPPS proposed rule, and we are including additional data requested by commenters. B. Policy Changes In section V.D.6. of this preamble, we are postponing the deadline for making the one-time prospective adjustment for the Federal rate at § 412.523(d)(3). In section VI.A. of this preamble, we are revising the existing payment adjustment for SSO cases. Also in section VI.A. of this preamble, we are sunsetting the surgical DRG exception to the payment policy established under the 3-day or less interruption of stay regulations at § 412.531(a)(1). In section VI.B. of this preamble, for LTCH hospitals within hospitals (HwHs) and LTCH satellites, we are clarifying at § 412.534(c) the policy for adjusting the LTCH PPS payment based on the amount that would be determined under the IPPS methodology. We state the methodology used for calculating the LTCH PPS payment amount that is equivalent to what would otherwise be paid under the IPPS. We are also codifying in regulations the general formula we currently use to give affect to the regulations as they pertain to calculating an amount under subpart O that is equivalent to an amount that would be determined under § 412.1(a). C. MedPAC Recommendations In section XII.A. of this preamble, we discuss the recommendation made in the March 2006 Report to Congress: Medicare Payment Policy to eliminate an update to payment rates for long-term care services for RY 2007. In section XII.B. of this preamble, we discuss Research Triangle Institute, International's (RTI) evaluation of the feasibility of adopting recommendations made in the June 2004 MedPAC report. In Appendix A of this final rule, we present a description of a preliminary model of an update framework under the LTCH PPS that we may propose to use in the future for purposes of the annual updating of the LTCH PPS Federal rate in future years. D. Impact In section XV. of this preamble, we analyze the impact of the changes presented in this final rule on Medicare expenditures, Medicare-participating LTCHs, and Medicare beneficiaries. IV. Long-Term Care Diagnosis-Related Group (LTC-DRG) Classifications and Relative Weights A. Background Section 123 of the BBRA specifically requires that the Secretary implement a PPS for LTCHs (that is, a per discharge system with a DRG-based patient classification system reflecting the differences in patient resources and costs in LTCHs while maintaining budget neutrality). Section 307(b)(1) of the BIPA modified the requirements of section 123 of the BBRA by specifically requiring that the Secretary examine “the feasibility and the impact of basing payment under such a system [the LTCH PPS] on the use of existing (or refined) hospital DRGs that have been modified to account for different resource use of LTCH patients as well as the use of the most recently available hospital discharge data.” In accordance with section 123 of the BBRA as amended by section 307(b)(1) of the BIPA and § 412.515, we use information derived from LTCH PPS patient records to classify these cases into distinct LTC-DRGs based on clinical characteristics and estimated resource needs. The LTC-DRGs used as the patient classification component of the LTCH PPS correspond to the hospital inpatient DRGs in the IPPS. We assign an appropriate weight to the LTC-DRGs to account for the difference in resource use by patients exhibiting the case complexity and multiple medical problems characteristic of LTCHs. In a departure from the IPPS, we use low volume LTC-DRGs (less than 25 LTCH cases) in determining the LTC-DRG weights, since LTCHs do not typically treat the full range of diagnoses as do acute care hospitals. In order to manage the large number of low volume DRGs (all DRGs with fewer than 25 cases), we group low volume DRGs into 5 quintiles based on average charge per discharge. (A listing of the current composition of low volume quintiles used in determining the FY 2006 LTC-DRG relative weights appears in the FY 2006 IPPS final rule (70 FR 47329 through 47332). A listing of the composition of proposed low volume quintiles used in determining the proposed FY 2007 LTC-DRG relative weights appears in the FY 2007 IPPS proposed rule (71 FR 24054 through 24058). We also account for adjustments to payments for cases in which the stay at the LTCH is less than or equal to five-sixths of the geometric ALOS and classify these cases as SSO cases. (A detailed discussion of the application of the Lewin Group model that was used to develop the LTC-DRGs appears in the August 30, 2002 LTCH PPS final rule (67 FR 55978).) B. Patient Classifications into DRGs Generally, under the LTCH PPS, a Medicare payment is made at a predetermined specific rate for each discharge; that payment varies by the LTC-DRG to which a beneficiary's stay is assigned. Cases are classified into LTC-DRGs for payment based on the following six data elements: (1) Principal diagnosis. (2) Up to eight additional diagnoses. (3) Up to six procedures performed. (4) Age. (5) Sex. (6) Discharge status of the patient. As indicated in the August 30, 2002 LTCH PPS final rule, upon the discharge of the patient from an LTCH, the LTCH must assign appropriate diagnosis and procedure codes from the most current version of the ICD-9-CM. HIPAA transactions and code sets standards regulations (45 CFR parts 160 and 162) require that no later than October 16, 2003, all covered entities must comply with the applicable requirements of subparts A and I through R of part 162. Among other requirements, those provisions direct covered entities to use the ASC X12N 837 Health Care Claim: Institutional, Volumes 1 and 2, version 4010, and the applicable standard medical data code sets for the institutional health care claim or equivalent encounter information transaction. (See 45 CFR 162.1002 and 45 CFR 162.1102). Medicare FIs enter the clinical and demographic information into their claims processing systems and subject this information to a series of automated screening processes called the Medicare Code Editor (MCE). These screens are designed to identify cases that require further review before assignment into a DRG can be made. During this process, the following types of cases are selected for further development: • Cases that are improperly coded. (For example, diagnoses are shown that are inappropriate, given the sex of the patient. Code 68.6, Radical abdominal hysterectomy, would be an inappropriate code for a male.) • Cases including surgical procedures not covered under Medicare. (For example, organ transplant in a non-approved transplant center.) • Cases requiring more information. (For example, ICD-9-CM codes are required to be entered at their highest level of specificity. There are valid 3-digit, 4-digit, and 5-digit codes. That is, code 262, Other severe protein-calorie malnutrition, contains all appropriate digits, but if it is reported with either fewer or more than 3 digits, the claim will be rejected by the MCE as invalid.) • Cases with principal diagnoses that do not usually justify admission to the hospital. (For example, code 437.9, unspecified cerebrovascular disease. While this code is valid according to the ICD-9-CM coding scheme, a more precise code should be used for the principal diagnosis.) After screening through the MCE, each claim will be classified into the appropriate LTC-DRG by the Medicare LTCH GROUPER software. As indicated in the August 30, 2002 LTCH PPS final rule, the Medicare GROUPER software, which is used under the LTCH PPS, is specialized computer software, and is the same GROUPER software program used under the IPPS. The GROUPER software was developed as a means of classifying each case into a DRG on the basis of diagnosis and procedure codes and other demographic information (age, sex, and discharge status). Following the LTC-DRG assignment, the Medicare FI determines the prospective payment by using the Medicare PRICER program, which accounts for hospital-specific adjustments. Under the LTCH PPS, we provide an opportunity for the LTCH to review the LTC-DRG assignments made by the FI and to submit additional information within a specified timeframe as specified in § 412.513(c). The GROUPER software is used both to classify past cases in order to measure relative hospital resource consumption to establish the DRG weights and to classify current cases for purposes of determining payment. The records for all Medicare hospital inpatient discharges are maintained in the MedPAR file. The data in this file are used to evaluate possible DRG classification changes and to recalibrate the DRG weights during our annual update under both the IPPS (§ 412.60(e)) and the LTCH PPS (§ 412.517). As discussed in greater detail in sections IV.D. and E. of this preamble, with the implementation of section 503(a) of the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA) (Pub. L. 108-173), there is the possibility that one feature of the GROUPER software program may be updated twice during a Federal fiscal year (FY) (October 1 and April 1) as required by the statute for the IPPS (69 FR 48954 through 48957). Specifically, as we discussed in the FY 2006 IPPS final rule, ICD-9-CM diagnosis and procedure codes for new medical technology may be created and added to existing DRGs in the middle of the Federal FY on April 1 (70 FR 47323). However, this policy change will have no effect on the LTC-DRG relative weights, which will continue to be updated only once a year (October 1), nor will there be any impact on Medicare payments under the LTCH PPS. The use of the ICD-9-CM code set is also compliant with the current requirements of the Transactions and Code Sets Standards regulations at 45 CFR parts 160 and 162, published in accordance with HIPAA. C. Organization of DRGs The DRGs are organized into 25 major diagnostic categories (MDCs), most of which are based on a particular organ system of the body; the remainder involve multiple organ systems (such as MDC 22, Burns). Accordingly, the principal diagnosis determines MDC assignment. Within most MDCs, cases are then divided into surgical DRGs and medical DRGs. Surgical DRGs are assigned based on a surgical hierarchy that orders operating room (O.R.) procedures or groups of O.R. procedures by resource intensity. The GROUPER software program does not recognize all ICD-9-CM procedure codes as procedures that affect DRG assignment, that is, procedures which are not surgical (for example, EKG), or minor surgical procedures (for example, 86.11, Biopsy of skin and subcutaneous tissue). The medical DRGs are generally differentiated on the basis of diagnosis. Both medical and surgical DRGs may be further differentiated based on age, sex, discharge status, and presence or absence of complications or comorbidities (CC). We note that CCs are defined by certain secondary diagnoses not related to, or not inherently a part of, the disease process identified by the principal diagnosis. (For example, the GROUPER software would not recognize a code from the 800.0x series, Skull fracture, as a CC when combined with principal diagnosis 850.4, Concussion with prolonged loss of consciousness, without return to preexisting conscious level.) In addition, we note that the presence of additional diagnoses does not automatically generate a CC, as not all DRGs recognize a comorbid or complicating condition in their definition. (For example, DRG 466, Aftercare without History of Malignancy as Secondary Diagnosis, is based solely on the principal diagnosis, without consideration of additional diagnoses for DRG determination.) In its June 2000, Report to Congress, MedPAC recommended that the Secretary “* * * improve the hospital inpatient prospective payment system by adopting, as soon as practicable, diagnosis-related group refinements that more fully capture differences in severity of illness among patients” (Recommendation 3A, p. 63). In response to that recommendation, we determined at that time that it was not practical to develop a refinement to inpatient hospital DRGs based on severity due to time and resource requirements. However, this does not preclude us from development of a severity-adjusted DRG refinement in the future. That is, a refinement to the list of CCs could be incorporated into the existing DRG structure. It is also possible that a more comprehensive severity adjusted structure may be created if a new code set is adopted. That is, if ICD-9-CM is replaced by ICD-10-CM (for diagnostic coding) and ICD-10-PCS (for procedure coding) or by other code sets, a severity concept may be built into the resulting DRG assignments. Of course, any change to the code set would be adopted through the process established in the HIPAA Administrative Simplification Standards provisions. In its March 2005 Report to Congress, “Physician-Owned Specialty Hospitals,” MedPAC recommended that the Secretary improve payment accuracy in the hospital IPPS by, among other things, “refining the current DRGs to more fully capture differences in severity of illness among patients” (Recommendation 1, p. 93). In the FY 2006 IPPS final rule (70 FR 47474 through 47479), we stated that we expected to make changes to the DRGs to better reflect severity of illness and we indicated that we plan to conduct a comprehensive review of the CCs list for FY 2007. We also indicated that we are considering the possibility of proposing to use the All Patient Refined (APR) DRGs under the IPPS for FY 2007. We explained that we did not propose to adopt the APR-DRGS under the IPPS for FY 2006 because it would represent a significant undertaking that could have a substantial effect on all hospitals and there was insufficient time to fully analyze a change of that magnitude. However, as an interim step to better recognize severity in the DRG system for FY 2006, until we could complete a more comprehensive analysis of the APR-DRG system and CC list as part of a complete analysis of the MedPAC recommendations that we planned to perform over the next year, we established cardiovascular DRGs 547 through 558 as described in the FY 2006 IPPS final rule (70 FR 47474 through 47478). In the FY 2007 IPPS proposed rule, we present the proposed changes to the DRG system for FY 2007 (71 FR 24049). In that rule, we proposed to use the IPPS GROUPER Version 24.0 for FY 2007 to process LTCH PPS claims for LTCH discharges occurring from October 1, 2006 through September 30, 2007 (71 FR 24049). As we also noted in that proposed rule, in its March 1, 2005 Report to Congress on Medicare Payment Policy (page 64) and Recommendation 1 in the 2005 Report to Congress on Physician-Owned Specialty Hospitals, MedPAC recommended that CMS, among other things, refine the current DRGs under the IPPS to more fully capture differences in severity of illness among patients. In evaluating this MedPAC recommendation for the IPPS, we are evaluating the APR-DRG Grouper used by MedPAC in its analysis. Based on this analysis, we developed a consolidated severity adjusted DRG system that we believe could be a better alternative for recognizing severity of illness among the Medicare population that we are considering to propose for future use under the IPPS. As discussed above in this section, the LTCH PPS uses the same patient classification system (that is, DRGs). In response to MedPAC recommendations that severity adjusted DRGs be adopted under the IPPS, we are examining the possibility of adopting a consolidated version of the APR-DRGs. In the event that severity adjusted DRGs, such as the consolidated severity adjusted DRGs, are adopted under the IPPS, we would need to consider whether to revise the patient classification system under the LTCH PPS. Any proposed changes to the patient classification system would be done through notice and comment rulemaking. D. Update of LTC-DRGs For FY 2006, the LTC-DRG patient classification system was based on LTCH data from the FY 2004 MedPAR file, which contained hospital bills data from the March 2005 update. The patient classification system consists of 526 DRGs that formed the basis of the FY 2006 LTCH PPS GROUPER program. The 526 LTC-DRGs included two “error DRGs.” As in the IPPS, we included two error DRGs in which cases that cannot be assigned to valid DRGs will be grouped. These two error DRGs are DRG 469 (Principal Diagnosis Invalid as a Discharge Diagnosis) and DRG 470 (Ungroupable). (See the FY 2006 IPPS final rule (70 FR 47323 through 47341)). The other 524 LTC-DRGs are the same DRGs used in the IPPS GROUPER program for FY 2006 (Version 23.0). In the past, the annual update to the CMS DRGs was based on the annual revisions to the ICD-9-CM codes and was effective each October 1. The ICD-9-CM coding update process was revised as discussed in greater detail in the FY 2005 IPPS final rule (69 FR 48954 through 48957). Specifically, section 503(a) of the MMA includes a requirement for updating ICD-9-CM codes twice a year instead of the current process of annual updates on October 1 of each year. This requirement is included as part of the amendments to the Act relating to recognition of new medical technology under the IPPS. (For additional information on this provision, including its implementation and its impact on the LTCH PPS, refer to the FY 2005 IPPS final rule (69 FR 48952 through 48957) and the RY 2006 LTCH PPS final rule (70 FR 24172 through 24177).) As discussed in the RY 2006 LTCH PPS final rule, with the implementation of section 503(a) of the MMA, there is the possibility that one feature of the GROUPER software program may be updated twice during a Federal FY (October 1 and April 1) as required by the statute for the IPPS (70 FR 24173 through 24175). Specifically, ICD-9-CM diagnosis and procedure codes for new medical technology may be created and added to existing DRGs in the middle of the Federal FY on April 1. No new LTC-DRGs will be created or deleted. Consistent with our current practice, any changes to the DRGs or relative weights will be made at the beginning of the next Federal FY (October 1). Therefore, there will not be any impact on Medicare payments under the LTCH PPS. The use of the ICD-9-CM code set is also compliant with the current requirements of the Transactions and Code Sets Standards regulations at 45 CFR parts 160 and 162, issued under HIPAA. As we explained in the FY 2006 IPPS final rule, historically in the health care industry annual changes to the ICD-9-CM codes were effective for discharges occurring on or after October 1 each year (70 FR 47323). Thus, the manual and electronic versions of the GROUPER software, which are based on the ICD-9-CM codes, were also revised annually and effective for discharges occurring on or after October 1 each year. The patient classification system used under the LTCH PPS (LTC-DRGs) is based on the DRG patient classification system used under the IPPS, which historically had been updated annually and effective for discharges occurring on or after October 1 through September 30 each year. As we also mentioned, the ICD-9-CM coding update process was revised as a result of the implementation of section 503(a) of the MMA, which includes a requirement for updating ICD-9-CM codes as often as twice a year instead of the current process of annual updates on October 1 of each year. As discussed in the FY 2005 IPPS final rule, this requirement is included as part of the amendments to the Act relating to recognition of new medical technology under the IPPS (69 FR 48954 through 48957). Section 503(a) of the MMA amended section 1886(d)(5)(K) of the Act by adding a new paragraph (vii) which states that “the Secretary shall provide for the addition of new diagnosis and procedure codes on April 1 [sic] of each year, but the addition of such codes shall not require the Secretary to adjust the payment (or diagnosis-related group classification) * * * until the fiscal year that begins after such date.” This requirement will improve the recognition of new technologies under the IPPS by accounting for those ICD-9-CM codes in the MedPAR claims data at an earlier date. Despite the fact that aspects of the GROUPER software may be updated to recognize any new technology ICD-9-CM codes, there will be no impact on either LTC-DRG assignments or payments under the LTCH PPS at that time. That is, changes to the LTC-DRGs (such as the creation or deletion of LTC-DRGs) and the relative weights will continue to be updated in the manner and timing (October 1) as they are now. Updates to the GROUPER software for both the IPPS and the LTCH PPS (for relative weights and the creation or deletion of DRGs) are made in the annual IPPS proposed and final rules and are effective each October 1. We also explained that since we do not publish a midyear IPPS rule, April 1 code updates will not be published in a midyear IPPS rule. Rather, we will assign any new diagnosis or procedure codes to the same DRG in which its predecessor code was assigned, so that there will be no impact on the DRG assignments until the following October 1. Any coding updates will be available through the websites provided in section IV.E. of this preamble and through the Coding Clinic for ICD-9-CM . Publishers and software vendors currently obtain code changes through these sources in order to update their code books and software system. If new codes are implemented on April 1, revised code books and software systems, including the GROUPER software program, will be necessary because we must use current ICD-9-CM codes. Therefore, for purposes of the LTCH PPS, because each ICD-9-CM code must be included in the GROUPER algorithm to classify each case into an LTC-DRG, the GROUPER software program used under the LTCH PPS would need to be revised to accommodate any new codes. In implementing section 503(a) of the MMA, there will only be an April 1 update if new technology codes are requested and approved. We note that any new codes created for April 1 implementation will be limited to those diagnosis and procedure code revisions primarily needed to describe new technologies and medical services. However, we reiterate that the process of discussing updates to the ICD-9-CM has been an open process through the ICD-9-CM Coordination and Maintenance Committee since 1995. Requestors will be given the opportunity to present the merits for a new code and make a clear and convincing case for the need to update ICD-9-CM codes through an April 1 update. Discharges between October 1, 2005, and September 30, 2006, (Federal FY 2006) are using Version 23.0 of the GROUPER software for both the IPPS and the LTCH PPS. Consistent with our current practice, any changes to the DRGs or relative weights will be made at the beginning of the Federal FY (October 1). We will notify LTCHs of any revised LTC-DRG relative weights based on the final DRGs and the applicable version of the GROUPER software program that will be effective October 1, 2006, in the annual IPPS proposed and final rules. At the September 2005 ICD-9-CM Coordination and Maintenance Committee meeting, there were no requests for an April 1, 2006 implementation of ICD-9-CM codes, and therefore, the next update to the ICD-9-CM coding system will not occur until October 1, 2006 (FY 2007). Presently, as there were no coding changes suggested for an April 1, 2006 update, the ICD-9-CM coding set implemented on October 1, 2005, will continue through September 30, 2006 (FY 2006). The next update to the LTC-DRGs and relative weights for FY 2007 will be presented in the FY 2007 IPPS proposed and final rules. Furthermore, we would notify LTCHs of any revisions to the GROUPER software used under the IPPS and LTCH PPS that would be implemented April 1, 2007. As noted previously in this section, in the FY 2007 IPPS proposed rule (71 FR 24050), we proposed to use Version 24.0 of the CMS GROUPER, which would be used under the IPPS for FY 2007, to classify cases for LTCH PPS discharges that would occur on or after October 1, 2006 and on or before September 30, 2007. E. ICD-9-CM Coding System 1. Uniform Hospital Discharge Data Set (UHDDS) Definitions Because the assignment of a case to a particular LTC-DRG will help determine the amount that will be paid for the case, it is important that the coding is accurate. Classifications and terminology used in the LTCH PPS are consistent with the ICD-9-CM and the UHDDS, as recommended to the Secretary by the National Committee on Vital and Health Statistics (“Uniform Hospital Discharge Data: Minimum Data Set, National Center for Health Statistics, April 1980”) and as revised in 1984 by the Health Information Policy Council (HIPC) of the Department of Health and Human Services (HHS). We note that the ICD-9-CM coding terminology and the definitions of principal and other diagnoses of the UHDDS are consistent with the requirements of the HIPAA Administrative Simplification Act of 1996 (45 CFR part 162). Furthermore, the UHDDS was used as a standard for the development of policies and programs related to hospital discharge statistics by both governmental and nongovernmental sectors for over 30 years. In addition, the following definitions (as described in the 1984 Revision of the UHDDS, approved by the Secretary for use starting January 1986) are requirements of the ICD-9-CM coding system, and have been used as a standard for the development of the CMS DRGs: • Diagnoses are defined to include all diagnoses that affect the current hospital stay. • Principal diagnosis is defined as the condition established after study to be chiefly responsible for occasioning the admission of the patient to the hospital for care. • Other diagnoses (also called secondary diagnoses or additional diagnoses) are defined as all conditions that coexist at the time of admission, that develop subsequently, or that affect the treatment received or the LOS or both. Diagnoses that relate to an earlier episode of care that have no bearing on the current hospital stay are excluded. • All procedures performed will be reported. This includes those that are surgical in nature, carry a procedural risk, carry an anesthetic risk, or require specialized training. We provide LTCHs with a 60-day window after the date of the notice of the initial LTC-DRG assignment to request review of that assignment. Additional information may be provided by the LTCH to the FI as part of that review. 2. Maintenance of the ICD-9-CM Coding System The ICD-9-CM Coordination and Maintenance (C&M) Committee is a Federal interdepartmental committee, co-chaired by the National Center for Health Statistics (NCHS) and CMS, that is charged with maintaining and updating the ICD-9-CM system. The C&M Committee is jointly responsible for approving coding changes, and developing errata, addenda, and other modifications to the ICD-9-CM to reflect newly developed procedures and technologies and newly identified diseases. The C&M Committee is also responsible for promoting the use of Federal and non-Federal educational programs and other communication techniques with a view toward standardizing coding applications and upgrading the quality of the classification system. The NCHS has lead responsibility for the ICD-9-CM diagnosis codes included in the Tabular List and Alphabetic Index for Diseases, while we have the lead responsibility for the ICD-9-CM procedure codes included in the Tabular List and Alphabetic Index for Procedures. The C&M Committee encourages participation by health-related organizations in this process and holds public meetings for discussion of educational issues and proposed coding changes twice a year at the CMS Central Office located in Baltimore, Maryland. The agenda and dates of the meetings can be accessed on our Web site at: http://www.cms.hhs.gov/ICD9ProviderDiagnosticCodes. As discussed previously in this section of the preamble, section 503(a) of the MMA includes a requirement for updating ICD-9-CM codes twice a year instead of the current process of annual updates on October 1 of each year. This requirement will improve the recognition of new technologies under the IPPS by accounting for them in the GROUPER software at an earlier date. Because this new statutory requirement could have a significant impact on health care providers, coding staff, publishers, system maintainers, and software systems, among others, we solicited comments on our proposed provisions to implement this requirement as part of the FY 2005 IPPS proposed rule (69 FR 28220 through 28221). We responded to comments and published our new policy regarding the updating of ICD-9-CM codes in the FY 2005 IPPS final rule (69 FR 48954 through 48957). While this new requirement states that the Secretary shall not adjust the payment of the DRG classification for any codes created for use on April 1, DRG software and other systems will have to be updated in order to recognize and accept the new codes. If any coding changes were implemented on April 1, the Medicare GROUPER software program used under both the IPPS and the LTCH PPS would need to be revised to reflect the new ICD-9-CM codes because the LTC-DRGs are the same DRGs used under the IPPS. Furthermore, although the GROUPER software used under both the IPPS and the LTCH PPS would need to be revised to accommodate the new codes effective April 1, there would be no additions or deletions of DRGs nor would the relative weights used under the IPPS and the LTCH PPS, respectively, be changed until the annual update on October 1 (to the extent that those changes are warranted), just as they are historically updated. As the LTCH PPS is based on the IPPS, we adopted the same approach used under the IPPS for potential April 1 ICD-9-CM coding changes. That is, we will assign any new diagnosis codes or procedure codes to the same DRG in which its predecessor code was assigned, so there will be no DRG impact in terms of potential DRG assignment until the following October 1. We will maintain the current method of publicizing any new code changes, as noted below. Current addendum and code title information is published on the CMS web page at: http://www.cms.hhs.gov/ICD9ProviderDiagnosticCodes/04_addendum.asp. Summary tables showing new, revised, and deleted code titles are also posted on the following CMS web page: http://www.cms.hhs.gov/ ICD9ProviderDiagnosticCodes/07_summarytables.asp. Information on ICD-9-CM diagnosis codes can be found at http://www.cms.hhs.gov/ICD9ProviderDiagnosticCodes/. Information on new, revised, and deleted ICD-9-CM codes is also available in the American Hospital Association (AHA) publication, the Coding Clinic for ICD-9-CM. AHA also distributes information to publishers and software vendors. We also send copies of all ICD-9-CM coding changes to our contractors for use in updating their systems and providing education to providers. If the April 1 changes are made to ICD-9-CM diagnosis or procedure codes, LTCHs will be required to obtain the new codes, coding books, or encoder updates, and make other system changes in order to capture and report the new codes. When we implemented section 503(a) of the MMA in the FY 2005 IPPS final rule, we indicated that we were aware of the additional burden this will have on health care providers. It should be noted that any new codes created for April 1 implementation will be limited to those diagnosis and procedure code revisions primarily needed to describe new technologies and medical services. However, we reiterate that the process for discussing updates to the ICD-9-CM has been an open process through the ICD-9-CM C&M Committee since 1995. Any requestor who makes a clear and convincing case for the need to update ICD-9-CM codes for purposes of the IPPS new technology add-on payment process through an April 1 update will be given the opportunity to present the merits of their proposed new code. At the September 2005 C&M Committee meeting, no new codes were proposed for update on April 1, 2006. While no DRG additions or deletions or changes to relative weights will occur prior to the usual October 1 update, in the event any new codes were created to describe new technologies and medical services through an April 1, 2006 update, under our policy established in the RY 2006 final rule (70 FR 24176), LTCH systems would have been expected to recognize and report those new codes through the channels as described in this section. The ICD-9-CM coding changes that have been adopted by the C&M Committee would become effective either at the beginning of each Federal FY (October 1) or, in the case of codes created to capture new technology, April 1 of each year. Coders will be expected to use the most current ICD-9-CM codes, as updated. Because we do not publish a mid-year IPPS rule, the currently accepted avenues of information dissemination will be used to inform all ICD-9-CM code users of any changes to the coding system. These avenues were described in section IV.D. of this preamble and were discussed at length in the FY 2005 IPPS final rule (69 FR 48956). Coders in LTCHs using the updated ICD-9-CM coding system will be on the same schedule as the rest of the health care industry. In the past, the updated ICD-9-CM was not available for use until October 1 of each year. Therefore, because the LTCH PPS and the IPPS use the same GROUPER software, the LTCH PPS will be directly affected by the statutory mandates directed at the IPPS as amended by section 503(a) of the MMA. (We note that there is no statutory requirement in the LTCH PPS to make additional payments for new technology.) The practical effect of this provision is that the GROUPER software must accept new ICD-9-CM codes reflecting the incorporation of new technologies into inpatient treatment at an acute care hospital prior to the scheduled annual update of the GROUPER software. Despite the fact that there are no provisions for additional payments for new technology under the LTCH PPS as there are under the IPPS, statutory compliance requires an alteration of the GROUPER software used under the IPPS, and since the LTCH PPS uses the same GROUPER software that is used under the IPPS, this consequently means that the GROUPER software used under the LTCH PPS would change. While DRG assignments would not change from October 1 through September 30, it is possible that there could be additional new ICD-9-CM diagnosis and procedure codes during that time, which would be assigned to predecessor DRGs. For both the IPPS and LTCH coders, it is possible that there will be ICD-9-CM codes in effect from October 1 through March 31, with additional ICD-9-CM codes in effect from April 1 through September 30. Presently, as there were no coding changes suggested for an April 1, 2006 update, the ICD-9-CM coding set implemented on October 1, 2005 will continue through September 30, 2006 (FY 2006). Of particular note to LTCHs are the invalid diagnosis codes (Table 6C) and the invalid procedure codes (Table 6D) located in the annual proposed and final rules for the IPPS. Claims with invalid codes are not processed by the Medicare claims processing system. 3. Coding Rules and Use of ICD-9-CM Codes in LTCHs We emphasize the need for proper coding by LTCHs. Inappropriate coding of cases can adversely affect the uniformity of cases in each LTC-DRG and produce inappropriate weighting factors at recalibration. We continue to urge LTCHs to focus on improved coding practices. Because of concerns raised by LTCHs concerning correct coding, we have asked the AHA to provide additional clarification or instruction on proper coding in the LTCH setting. The AHA will provide this instruction via their established process of addressing questions through their publication, the Coding Clinic for ICD-9-CM . Written questions or requests for clarification may be addressed to the Central Office on ICD-9-CM, American Hospital Association, One North Franklin, Chicago, IL 60606. A form for question(s) is available for download and can be mailed on AHA's Web site at: http://www.ahacentraloffice.org . In addition, current coding guidelines are available at the NCHS Web site: http://www.cdc.gov/nchs/datawh/ftpserv/ftpicd9/ftpicd9.htm#conv . In conjunction with the cooperating parties (AHA, the American Health Information Management Association (AHIMA), and NCHS), we reviewed actual medical records and are concerned about the quality of the documentation under the LTCH PPS, as was the case at the beginning of the IPPS. We fully believe that, with experience, the quality of the documentation and coding will improve, as it did for the IPPS. The cooperating parties have plans to assist their members with improvement in documentation and coding issues for the LTCHs through specific questions and coding guidelines. The importance of good documentation is emphasized in the revised ICD-9-CM Official Guidelines for Coding and Reporting: “A joint effort between the attending physician and coder is essential to achieve complete and accurate documentation, code assignment, and reporting of diagnoses and procedures. The importance of consistent, complete documentation in the medical record cannot be overemphasized. Without this documentation, the application of all coding guidelines is a difficult, if not impossible, task” ( Coding Clinic for ICD-9-CM , Fourth Quarter 2002, page 115). To improve medical record documentation, LTCHs should be aware that if the patient is being admitted for continuation of treatment of an acute or chronic condition, guidelines at Section I.B.10 of the Coding Clinic for ICD-9-CM , Fourth Quarter 2002 (page 129) are applicable for the selection of principal diagnosis. To clarify coding advice issued in the August 30, 2002 final rule (67 FR 55979), at Guideline I.B.12, Late Effects, we state that a late effect is considered to be the residual effect (condition produced) after the acute phase of an illness or injury has terminated ( Coding Clinic for ICD-9-CM , Fourth Quarter 2002, page 129). Regarding whether a LTCH should report the ICD-9-CM code(s) for an unresolved acute condition instead of the code(s) for late effects of rehabilitation, we emphasize that each case must be evaluated on its unique circumstances and coded appropriately. Depending on the documentation in the medical record, either a code reflecting the acute condition or rehabilitation could be appropriate in a LTCH. Since implementation of the LTCH PPS, our Medicare FIs have conducted training and provided assistance to LTCHs in correct coding. We have also issued manuals containing procedures as well as coding instructions to LTCHs and FIs. We will continue to conduct training and provide guidance on an as-needed basis. We also refer readers to the detailed discussion on correct coding practices in the August 30, 2002 LTCH PPS final rule (67 FR 55981 through 55983). Additional coding instructions and examples will be published in the Coding Clinic for ICD-9-CM . F. Method for Updating the LTC-DRG Relative Weights As discussed in the August 30, 2002 LTCH PPS final rule that implemented the LTCH PPS, under the LTCH PPS, each LTCH will receive a payment that represents an appropriate amount for the efficient delivery of care to Medicare patients (67 FR 55984). The system must be able to account adequately for each LTCH's case-mix in order to ensure both a fair distribution of Medicare payments and access to adequate care for those Medicare patients whose care is more costly. Therefore, in § 412.523(c), we adjust the standard Federal PPS rate by the LTC-DRG relative weights in determining payment to LTCHs for each case. Under this payment system, relative weights for each LTC-DRG are a primary element used to account for the variations in cost per discharge and resource utilization among the payment groups as described in § 412.515. To ensure that Medicare patients who are classified to each LTC-DRG have access to an appropriate level of services and to encourage efficiency, we calculate a relative weight for each LTC-DRG that represents the resources needed by an average inpatient LTCH case in that LTC-DRG. For example, cases in a LTC-DRG with a relative weight of 2 will, on average, cost twice as much as cases in a LTC-DRG with a weight of 1. As we discussed in the FY 2006 IPPS final rule, the LTC-DRG relative weights effective under the LTCH PPS for Federal FY 2006 were calculated using the March 2005 update of FY 2004 MedPAR data and Version 23.0 of the GROUPER software (70 FR 47325). We use total days and total charges in the calculation of the LTC-DRG relative weights. By nature, LTCHs often specialize in certain areas, such as ventilator-dependent patients and rehabilitation and wound care. Some case types (DRGs) may be treated, to a large extent, in hospitals that have, from a perspective of charges, relatively high (or low) charges. Distribution of cases with relatively high (or low) charges in specific LTC-DRGs has the potential to inappropriately distort the measure of average charges. To account for the fact that cases may not be randomly distributed across LTCHs, we use a hospital-specific relative value method to calculate relative weights. We believe this method removes this hospital-specific source of bias in measuring average charges. Specifically, we reduce the impact of the variation in charges across providers on any particular LTC-DRG relative weight by converting each LTCH's charge for a case to a relative value based on that LTCH's average charge. (See the FY 2006 IPPS final rule for further information on the hospital-specific relative value methodology (70 FR 47328 through 47329).) To account for LTC-DRGs with low volume (that is, with fewer than 25 LTCH cases), we grouped those low volume LTC-DRGs into 1 of 5 categories (quintiles) based on average charges, for the purposes of determining relative weights. For FY 2006, based on the FY 2004 MedPAR data, we identified 171 LTC-DRGs that contained between 1 and 24 cases. This list of low volume LTC-DRGs was then divided into 1 of the 5 low volume quintiles, each containing a minimum of 34 LTC-DRGs (171/5 = 34 with 1 LTC-DRG as a remainder). Each of the low volume LTC-DRGs grouped to a specific quintile received the same relative weight and ALOS using the formula applied to the regular LTC-DRGs (25 or more cases). (See the FY 2006 IPPS final rule for further explanation of the development and composition of each of the 5 low volume quintiles for FY 2006 (70 FR 47329 through 47332).) After grouping the cases in the appropriate LTC-DRG, we calculated the relative weights by first removing statistical outliers and cases with a LOS of 7 days or less. Next, we adjusted the number of cases remaining in each LTC-DRG for the effect of short-stay outlier cases under § 412.529. The short-stay adjusted discharges and corresponding charges were used to calculate “relative adjusted weights” in each LTC-DRG using the hospital-specific relative value method. We also adjusted the LTC-DRG relative weights to account for nonmonotonically increasing relative weights. That is, we made an adjustment if cases classified to the LTC-DRG “with complications or comorbidities (CCs)” of a “with CC”/”without CC” pair had a lower average charge than the corresponding LTC-DRG “without CCs” by assigning the same weight to both LTC-DRGs in the “with CC”/”without CC” pair. (See the FY 2006 IPPS final rule for further details on the steps for calculating the LTC-DRG relative weights (70 FR 47336 through 47341).) In addition, of the 526 LTC-DRGs in the LTCH PPS for FY 2006, based on LTCH cases in the FY 2004 MedPAR files, we identified 196 LTC-DRGs for which there were no LTCH cases in the database. That is, no patients who would have been classified to those DRGs were treated in LTCHs during FY 2004 and, therefore, no charge data were reported for those DRGs. Thus, in the process of determining the relative weights of LTC-DRGs, we were unable to determine weights for these 196 LTC-DRGs using the method described in this section of the preamble. However, since patients with a number of the diagnoses under these LTC-DRGs may be treated at LTCHs beginning in FY 2006, we assigned relative weights to each of the 196 “no volume” LTC-DRGs based on clinical similarity and relative costliness to one of the remaining 330 (526−196 = 330) LTC-DRGs for which we were able to determine relative weights, based on the FY 2004 claims data. (A list of the current no-volume LTC-DRGs and further explanation of their FY 2006 relative weight assignment can be found in the FY 2006 IPPS final rule (70 FR 47337 through 47341).) Furthermore, for FY 2006, we established LTC-DRG relative weights of 0.0000 for heart, kidney, liver, lung, and simultaneous pancreas/kidney transplants (LTC-DRGs 103, 302, 480, 495, 512 and 513, respectively) because Medicare will only cover these procedures if they are performed at a hospital that has been certified for the specific procedures by Medicare and presently no LTCH has been so certified. If in the future, however, a LTCH applies for certification as a Medicare-approved transplant center, we believe that the application and approval procedure would allow sufficient time for us to propose appropriate weights for the LTC-DRGs affected. At the present time, we included these 6 transplant LTC-DRGs in the GROUPER software program for administrative purposes. As the LTCH PPS uses the same GROUPER software program for LTCHs as is used under the IPPS, removing these DRGs would be administratively burdensome. As we noted previously, there were no new ICD-9-CM code requests for an April 1, 2006 update. Therefore, Version 23.0 of the DRG GROUPER software established in the FY 2006 IPPS final rule (70 FR 47284 through 47322) will continue to be effective until October 1, 2006. Moreover, the LTC-DRGs and relative weights for FY 2006 established in that same IPPS final rule (70 FR 47681 through 47689) will continue to be effective until October 1, 2006, (just as they would have been even if there had been any new ICD-9-CM code requests for an April 1, 2006 update). Accordingly, Table 3 in the Addendum to this final rule lists the LTC-DRGs and their respective relative weights, geometric ALOS, and five-sixths of the geometric ALOS that we will continue to use for the period of July 1, 2006 through September 30, 2006. (This table is the same as table 11 of the Addendum to the FY 2006 IPPS final rule (70 FR 47681 through 47689). The next update to the ICD-9-CM coding system was presented in the FY 2007 IPPS proposed rule (since there will be no April 1, 2006 updates to the ICD-9-CM coding system). In addition, the proposed DRGs and GROUPER for FY 2007 that would be used for the IPPS and the LTCH PPS, effective October 1, 2006, were presented in the IPPS FY 2007 proposed rule in the Federal Register (71 FR 24049 through 24068). As discussed in that proposed rule, we proposed to calculate the proposed LTC-DRG relative weights for FY 2007 using total Medicare allowable charges from FY 2005 Medicare LTCH bill data from the December 2005 update of the MedPAR file, which were the best available data at that time, and we used the proposed Version 24.0 of the CMS GROUPER, which would be the same GROUPER that we proposed to use under the IPPS in FY 2007 to classify cases. Furthermore, to calculate the final LTC-DRG relative weights for FY 2007, we proposed that if more recent data are available (for example, data from the March 2006 update of the MedPAR file), we would use that data and use the finalized Version 24.0 of the CMS GROUPER. Table 11 of the Addendum to the FY 2007 IPPS proposed rule lists the proposed LTC-DRGs and their respective proposed relative weights, proposed geometric ALOS, and proposed five-sixths of the geometric ALOS that would be effective for LTCH PPS discharges occurring on or after October 1, 2006 through September 30, 2007 (71 FR 24394 through 24403). V. Changes to the LTCH PPS Payment Rates for the 2007 LTCH PPS Rate Year A. Overview of the Development of the Payment Rates The LTCH PPS was effective for a LTCH's first cost reporting period beginning on or after October 1, 2002. Effective with that cost reporting period, LTCHs are paid, during a 5-year transition period, on the basis of an increasing proportion of the LTCH PPS Federal rate and a decreasing proportion of a hospital's payment under the reasonable cost-based payment system, unless the hospital makes a one-time election to receive payment based on 100 percent of the Federal rate (see § 412.533). New LTCHs (as defined at § 412.23(e)(4)) are paid based on 100 percent of the Federal rate, with no phase-in transition payments. The basic methodology for determining LTCH PPS Federal prospective payment rates is set forth in the regulations at § 412.515 through § 412.532. Below we discuss the factors that will be used to update the LTCH PPS standard Federal rate for the 2007 LTCH PPS rate year that will be effective for LTCH discharges occurring on or after July 1, 2006 through June 30, 2007. When we implemented the LTCH PPS in the August 30, 2002 final rule (67 FR 56029 through 56031), we computed the LTCH PPS standard Federal payment rate for FY 2003 by updating the best available (FY 1998 or FY 1999) Medicare inpatient operating and capital costs per case data, using the excluded hospital market basket. Section 123(a)(1) of the BBRA requires that the PPS developed for LTCHs be budget neutral for the initial year of implementation. Therefore, in calculating the standard Federal rate under § 412.523(d)(2), we set total estimated LTCH PPS payments equal to estimated payments that would have been made under the reasonable cost-based payment methodology had the PPS for LTCHs not been implemented. Section 307(a) of the BIPA specified that the increases to the hospital-specific target amounts and the cap on the target amounts for LTCHs for FY 2002 provided for by section 307(a)(1) of the BIPA shall not be considered in the development and implementation of the LTCH PPS. Furthermore, as specified at § 412.523(d)(1), the standard Federal rate is reduced by an adjustment factor to account for the estimated proportion of outlier payments under the LTCH PPS to total estimated LTCH PPS payments (8 percent). For further details on the development of the FY 2003 standard Federal rate, see the August 30, 2002 LTCH PPS final rule (67 FR 56027 through 56037), and for subsequent updates to the LTCH PPS Federal rate, refer to the following final rules: RY 2004 LTCH PPS final rule (68 FR 34134 through 34140), RY 2005 LTCH PPS final rule (69 FR 25682 through 25684), and RY 2006 LTCH PPS final rule (70 FR 24179 through 24180). B. LTCH PPS Market Basket Historically, the Medicare program used a market basket to account for price increases of the services furnished by providers. The market basket used for the LTCH PPS includes both operating and capital-related costs of LTCHs because the LTCH PPS uses a single payment rate for both operating and capital-related costs. The development of the LTCH PPS standard Federal rate is discussed in further detail in the August 30, 2002 LTCH PPS final rule (67 FR 56027 through 56033). In the August 30, 2002 final rule (67 FR 56016 through 56017 and 56030), which implemented the LTCH PPS, we established the use of the excluded hospital with capital market basket as the LTCH PPS market basket. The excluded hospital market basket was used to update the limits on LTCHs' operating costs for inflation under the former reasonable cost-based (TEFRA) payment system. We explained in that same final rule that we believe that the use of the excluded hospital market basket to update LTCHs' costs for inflation was appropriate because the excluded hospital market basket (with a capital component) measures price increases of the services furnished by excluded hospitals, including LTCHs. Since the costs of LTCHs are included in the excluded hospital market basket, this market basket index, in part, also reflects the costs of LTCHs. However, in order to capture the total costs (operating and capital-related) of LTCHs, we added a capital component to the excluded hospital market basket for use under the LTCH PPS. We refer to this index as the “Excluded Hospital with Capital” market basket. Currently, the excluded hospital with capital market basket used to update LTCH PPS payments is based on 1997 Medicare cost report data and includes Medicare participating psychiatric, rehabilitation, long term care, cancer, and childrens hospitals (68 FR 34137). (For further details on the development of the FY 1997-based excluded hospital with capital market basket used under the LTCH PPS, see the RY 2004 LTCH PPS final rule (68 FR 34134 through 34137)). In the RY 2006 LTCH PPS final rule (70 FR 24179), we noted that based on our research, we did not develop a market basket specific to LTCH services. Presently, we are still unable to create a separate market basket specifically for LTCHs due to the small number of facilities and the limited data that are provided (for instance, approximately 15 percent of LTCHs reported contract labor cost data for 2002). We noted in that same final rule that we would discuss the use of the “Rehabilitation, Psychiatric and Long-Term Care (RPL) market basket” under the LTCH PPS, which is currently used under the inpatient rehabilitation facility (IRF) PPS. The RPL market basket is based on the operating and capital costs of IRFs, inpatient psychiatric facilities (IPFs) and LTCHs. Since all IRFs are now paid under the IRF PPS Federal payment rate, nearly all LTCHs are paid 100 percent of the Federal rate under the LTCH PPS, and most IPFs are transitioning to payment based on 100 percent of the Federal per diem payment amount under the IPF PPS (payments will be based on 100 percent of the Federal rate for cost reporting periods beginning on or after January 1, 2008), under the broad authority conferred upon the Secretary by section 123 of the BBRA as amended by section 307(b) of the BIPA to develop the LTCH PPS, in the RY 2007 LTCH PPS proposed rule (71 FR 4659), we proposed to adopt the RPL market basket as the appropriate market basket of goods and services under the LTCH PPS for discharges occurring on or after July 1, 2006. In that proposed rule, we proposed that we would adopt the RPL market basket based on FY 2002 cost report data beginning in the 2007 LTCH PPS rate year, under the LTCH PPS. We chose to use the FY 2002 Medicare cost reports because these are the most recent, relatively complete cost data for IRFs, IPFs, and LTCHs serving Medicare beneficiaries. As also discussed in that proposed rule, the RPL market basket reflects the operating and capital cost structures for IRFs, IPFs, and LTCHs. We proposed to exclude children's hospitals, cancer hospitals, and religious nonmedical healthcare institutions (RNHCIs) from the RPL market basket because their payments are based entirely on reasonable costs subject to rate-of-increase limits established under the authority of section 1886(b) of the Act, and implemented in § 413.40. Children's hospitals, cancer hospitals, and RNHCIs are not reimbursed under a PPS. Also, based on FY 2002 data, the cost structures for these hospitals are noticeably different than the cost structures of the IRFs, IPFs, and LTCHs. The services offered in IRFs, IPFs, and LTCHs are typically more labor-intensive than those offered in cancer hospitals, children's hospitals, and RNHCIs. Therefore, the compensation cost weights for IRFs, IPFs, and LTCHs are larger than those in cancer hospitals, children's hospitals, and RNHCIs. In addition, the depreciation cost weights for IRFs, IPFs, and LTCHs are noticeably smaller than those for children's hospitals, cancer hospitals, and RNCHIs. Therefore, including the fact that IRFs, IPFs, and LTCHs are subject to a PPS while children's hospitals, cancer hospitals and RNCHIs continue to receive payment based on reasonable costs, we believe a market basket based on the data of IRFs, IPFs, and LTCHs is appropriate to use under the LTCH PPS since it is the best available data that would reflect the cost structures of LTCHs. Comment: We received several comments supporting our proposal to adopt the RPL market basket based on FY 2002 cost report data under the LTCH PPS, beginning in the 2007 LTCH PPS rate year. Along with their endorsement of this proposal, a few commenters stated that the proposed capital weight methodology may be skewed. As previously stated in this rule, we stated in the proposed rule that the depreciation cost weights for IRFs, IPFs, and LTCHs are smaller than those for children's and cancer hospitals. The commenter noted that since most LTCHs are “units within hospitals” (that is, hospitals-within-hospitals), the proposed methodology may be more heavily aligned with a “unit” perspective as proposed to a “freestanding hospital” perspective. The commenters claim that freestanding LTCHs will have higher depreciation costs, which are probably closer to those associated with children's and cancer hospitals. Response: The RPL market basket is based on data from freestanding IRFs, IPFs, and LTCHs. As a general rule, we do not include hospital-based facilities in our market baskets because expense data for a hospital-based facility are influenced by the allocation of overhead over the entire institution. Due to this method of allocation, total expenses will be correct, but the expenses of the individual components may be skewed. The cost structures of freestanding LTCHs should reflect purchasing patterns of the average LTCH. Our analysis of depreciation cost weights is based on freestanding facilities. This depreciation cost weight (depreciation costs as a percent of total capital costs) for freestanding LTCHs is approximately 57 percent compared to 85 percent for children's and cancer hospitals. Therefore, we do not believe that the proposed capital weight methodology is skewed (that is, more heavily aligned with a hospital-based perspective since they are not included in our market basket). Rather, we believe the RPL market basket accurately reflects the capital cost structure of freestanding LTCHs serving Medicare beneficiaries. In the following discussion, we provide a background on market baskets and describe the methodologies we used to develop the operating and capital portions of the FY 2002-based RPL market basket that we are adopting for use under the LTCH PPS beginning in RY 2007 under broad authority conferred upon the Secretary by section 123 of the BBRA as amended by section 307(b) of the BIPA. 1. Overview of the RPL Market Basket The RPL market basket is a fixed weight, Laspeyres-type price index that is constructed in three steps. First, a base period is selected (in this case, FY 2002) and total base period expenditures are estimated for a set of mutually exclusive and exhaustive spending categories based upon type of expenditure. Then the proportion of total costs that each category represents is determined. These proportions are called cost or expenditure weights. Second, each expenditure category is matched to an appropriate price or wage variable, referred to as a price proxy. In nearly every instance, these price proxies are price levels derived from publicly available statistical series that are published on a consistent schedule, preferably at least on a quarterly basis. Finally, the expenditure weight for each cost category is multiplied by the level of its respective price proxy for a given period. The sum of these products (that is, the expenditure weights multiplied by their price levels) for all cost categories yields the composite index level of the market basket in a given period. Repeating this step for other periods produces a series of market basket levels over time. Dividing an index level for a given period by an index level for an earlier period produces a rate of growth in the input price index over that time period. A market basket is described as a fixed-weight index because it answers the question of how much it would cost, at another time, to purchase the same mix of goods and services purchased to provide hospital services in a base period. The effects on total expenditures resulting from changes in the quantity or mix of goods and services (intensity) purchased subsequent to the base period are not measured. In this manner, the market basket measures only pure price change. Only when the index is rebased would the quantity and intensity effects be captured in the cost weights. Therefore, we rebase the market basket periodically so that cost weights reflect changes in the mix of goods and services that hospitals purchase (hospital inputs) to furnish patient care between base periods. The terms rebasing and revising, while often used interchangeably, actually denote different activities. Rebasing means moving the base year for the structure of costs of an input price index (for example, shifting the base year cost structure from FY 1997 to FY 2002). Revising means changing data sources, methodology, or price proxies used in the input price index. In this final rule, we are rebasing and revising the market basket used to update the LTCH PPS. Specifically, as noted above in this section and as we proposed in the RY 2007 LTCH PPS proposed rule (71 FR 4659 through 4666), beginning in the 2007 LTCH PPS rate year, we are using the FY 2002-based RPL market basket, which is described in greater detail below in this section. 2. Methodology for the Operating Portion of the RPL Market Basket The operating portion of the FY 2002-based RPL market basket consists of several major cost categories derived from the FY 2002 Medicare cost reports for IRFs, IPFs, and LTCHs: Wages, drugs, professional liability insurance (PLI), and a residual “all other” category. We choose to use the FY 2002 Medicare cost reports because these are the most recent, relatively complete cost data for IRFs, IPFs, and LTCHs serving Medicare beneficiaries. Generally, if detailed cost data are not available for these Medicare cost reports, we prefer to use the IPPS hospital Medicare cost reports to supplement IPF, IRF, and LTCH data because this is a comprehensive source of cost data for hospitals serving Medicare beneficiaries. When the IPPS Medicare cost report data are not available, we choose the best publicly available data source, such as the Bureau of Economic Analysis Input-Output (I-O) Tables. We use the IRF, IPF, and LTCH Medicare cost reports to derive these major cost categories for the RPL market basket which include wages, drugs, PLI, and a residual “all other” category. As stated above in this section, we are using FY 2002 as the base year because we believe this is the most recent, relatively complete year of Medicare cost report data. Due to insufficient Medicare cost report data for IRFs, IPFs, and LTCHs, we will develop cost weights for benefits, contract labor, and blood and blood products using the FY 2002-based IPPS market basket (70 FR 23384), which we explain in more detail later in this section. For example, less than 30 percent of IRFs, IPFs, and LTCHs reported benefit cost data in FY 2002. We noticed an increase in the cost data for these expense categories over the last 4 years. (We note that in the future, there may be sufficient IRF, IPF, and LTCH cost report data to develop the weights for these expenditure categories.) Since the cost weights for the RPL market basket are based on facility costs, we are limiting our sample to hospitals with a Medicare average length of stay (ALOS) within a comparable range of the total facility ALOS. We believe this provides a more accurate reflection of the structure of costs for Medicare treatments. Our goal is to measure cost shares that are reflective of case-mix and practice patterns associated with providing services to Medicare beneficiaries. We are using those cost reports for IRFs and LTCHs whose Medicare ALOS is within 15 percent (that is, 15 percent higher or lower) of the total facility ALOS for the hospital. This is the same edit applied to the FY 1992-based and FY 1997-based excluded hospital with capital market basket. Consistent with the development of the RPL market basket adopted under the IRF PPS in the FY 2006 IRF PPS final rule (70 FR 47909), we will use 15 percent because it includes those LTCHs and IRFs whose Medicare ALOS is within approximately 5 days of the facility ALOS. We believe this edit provides us with a representative sample of LTCHs and IRFs serving Medicare beneficiaries. We are using a less stringent measure of Medicare ALOS for IPFs whose ALOS is within 30 or 50 percent (depending on the total facility ALOS) of the total facility ALOS. This less stringent edit allows us to increase our sample size by over 150 reports and produce a cost weight more consistent with the overall facility. When developing the FY 1997-based excluded hospital with capital market basket, the edit we applied to IPFs was based on the best available data at the time. The detailed cost categories under the residual (that is, the remaining portion of the market basket after excluding wages and salaries, drugs, and professional liability cost weights) are derived from the FY 2002-based IPPS market basket and the 1997 Benchmark I-O Tables published by the Bureau of Economic Analysis, U.S. Department of Commerce. The FY 2002-based IPPS market basket was developed using FY 2002 Medicare hospital cost reports with the most recent and detailed cost data (70 FR 47388). The 1997 Benchmark I-O is the most recent, comprehensive source of cost data for all hospitals. The RPL cost weights for benefits, contract labor, and blood and blood products were derived using the FY 2002-based IPPS market basket. For example, the ratio of the benefit cost weight to the wages and salaries cost weight in the FY 2002-based IPPS market basket was applied to the RPL wages and salaries cost weight to derive a benefit cost weight for the RPL market basket. The remaining RPL operating cost categories were derived using the 1997 Benchmark I-O Tables, aged to 2002 using relative price changes. (The methodology we used to age the data involves applying the annual price changes from the price proxies to the appropriate cost categories. We repeat this practice for each year.) Therefore, using this methodology, roughly 59 percent of the RPL market basket is accounted for by wages, drugs, and PLI data from FY 2002 Medicare cost report data for IRFs, IPFs, and LTCHs. Comment: Several commenters propose that we regularly re-analyze the RPL cost report data, which are the basis of the RPL market basket. They note that the methodology used for the RPL market basket includes data from the IPPS hospital market basket. These commenters encouraged us to work with providers to improve the cost reports from IRFs, IPFs, and LTCHs to ensure that the data used for the RPL market basket represent only the types of excluded hospitals for which the RPL market basket was developed. Furthermore, they believe that improving the data reported on the cost reports of IRFs, IPFs, and LTCHs would not only refine the RPL market basket but also would improve the accuracy of the labor-related share to which the wage index is applied. Response: As noted above in this section, we rely on the IPPS hospital cost report data to supplement the IRF, IPF, and LTCH Medicare cost report data for benefits, contract labor, and blood and blood products. For example, the ratio of the benefit cost weight to the wages and salaries cost weight in the FY 2002-based IPPS market basket is applied to the RPL wages and salaries cost weight to derive a benefit cost weight for the RPL market basket. We did not directly use the IPPS Medicare cost report data, rather we used these data to determine the relationships between benefits, contract labor, and blood and blood products with wages and salaries. The wages and salaries cost weight in the RPL market basket is derived using the IRF, IPF and LTCH Medicare cost reports and accounts for 50 percent of the RPL market basket. As noted above in this section and as discussed in the RY 2007 LTCH PPS proposed rule (71 FR 4660), due to data limitations, this was the best methodology for developing the latter cost weights. We agree with the commenters that improving the data reported on the cost reports of IRFs, IPFs, and LTCHs could improve the RPL market basket and labor-related share. We have noticed this data improvement on other provider-type cost reports. Therefore, we encourage IRFs, IPFs, and LTCHs to fully complete their cost reports; this would help us in developing the most complete and accurate market basket possible. We will continue to analyze RPL cost report data on a regular basis. The following is a summary outlining the choice of the proxies we used for the operating portion of the market basket. The price proxies for the capital portion are described in more detail in section V.B.3. of this preamble. With the exception of the Professional Liability proxy, all the price proxies for the operating portion of the RPL market basket are based on Bureau of Labor Statistics (BLS) data and are grouped into one of the following BLS categories: • Producer Price Indexes (PPIs) measure price changes for goods sold in other than retail markets. PPIs are preferable price proxies for goods that hospitals purchase as inputs in producing their outputs because the PPIs would better reflect the prices faced by hospitals. For example, we will use a special PPI for prescription drugs, rather than the Consumer Price Index (CPI) for prescription drugs because hospitals generally purchase drugs directly from the wholesaler. The PPIs that we use measure price change at the final stage of production. • Consumer Price Indexes (CPIs) measure changes in the prices of final goods and services bought by the typical consumer. Because they may not represent the price faced by a producer, we use CPIs only if an appropriate PPI were not available, or if the expenditures were more similar to those of retail consumers in general rather than purchases at the wholesale level. For example, the CPI for food purchases away from home is used as a proxy for contracted food services. • Employment Cost Indexes (ECIs) measure the rate of change in employee wage rates and employer costs for employee benefits per hour worked. These indexes are fixed-weight indexes and strictly measure the change in wage rates and employee benefits per hour. Appropriately, they are not affected by shifts in employment mix. We evaluated the price proxies using the criteria of reliability, timeliness, availability, and relevance. Reliability indicates that the index is based on valid statistical methods and has low sampling variability. Widely accepted statistical methods ensure that the data were collected and aggregated in a way that can be replicated. Low sampling variability is desirable because it indicates that the sample reflects the typical members of the population. (Sampling variability is variation that occurs by chance because a sample was surveyed rather than the entire population.) Timeliness implies that the proxy is published regularly, preferably at least once a quarter. The market baskets are updated quarterly, and therefore, it is important that the underlying price proxies be up-to-date, reflecting the most recent data available. We believe that using proxies that are published regularly (at least quarterly, when possible) helps to ensure that we are using the most recent data available to update the market basket. We strive to use publications that are disseminated frequently because we believe that this is an optimal way to stay abreast of the most current data available. Availability means that the proxy is publicly available. We prefer that our proxies are publicly available because this will help ensure that our market basket updates are as transparent to the public as possible. In addition, this enables the public to be able to obtain the price proxy data on a regular basis. Finally, relevance means that the proxy is applicable and representative of the cost category weight to which it is applied. The CPIs, PPIs, and ECIs selected by us for this final rule meet these criteria. Therefore, we believe that they continue to be the best measure of price changes for the cost categories to which they would be applied. We note that the proxies are the same as those used for the FY 1997-based excluded hospital with capital market basket, which is currently used under the LTCH PPS, and are the same proxies as those used for the FY 2002-based excluded hospital market basket that is used to update the reasonable cost-based portion of LTCHs' blended transition payments (70 FR 47399 through 47403). Because these proxies meet our criteria of reliability, timeliness, availability, and relevance, we believe they continue to be the best measure of price changes for the cost categories. For further discussion on the FY 1997-based excluded hospital with capital market basket, see the RY 2004 LTCH PPS final rule (68 FR 34134 through 34136). For further discussion on the FY 2002-based excluded hospital market basket, see the FY 2006 IPPS final rule (70 FR 47400 through 47403). Table 2 sets forth the complete 2002-based RPL market basket including cost categories, weights, and price proxies for the operating portion of the market basket. The price proxies for the capital portion are described in more detail in the capital methodology section. For comparison purposes, the corresponding FY 1997-based excluded hospital with capital market basket, which is currently used under the LTCH PPS, is also listed. Wages and salaries are 52.895 percent of total costs for the FY 2002-based RPL market basket compared to 47.335 percent for the FY 1997-based excluded hospital with capital market basket. Employee benefits are 12.982 percent for the FY 2002-based RPL market basket compared to 10.244 percent for the FY 1997-based excluded hospital with capital market basket. As a result, compensation costs (wages and salaries plus employee benefits) for the FY 2002-based RPL market basket are 65.877 percent of costs compared to 57.579 percent for the FY 1997-based excluded hospital with capital market basket. Of the 8 percentage-point difference between the compensation shares, approximately 3 percentage points are due to the new base year (FY 2002 instead of FY 1997), 3 percentage points are due to revised LOS edit (that is, including only IRFs and LTCHs whose Medicare ALOS is within 15 percent of the total facility ALOS for the hospital and including only IPFs whose Medicare ALOS in within 30 or 50 percent of the total facility ALOS), and the remaining 2 percentage points are due to the exclusion of other types of IPPS-excluded hospitals (that is, only including IPFs, IRFs, and LTCHs in the market basket and excluding childrens hospitals, cancer hospitals, and RNCHIs).

Note: Due to rounding, weights may not sum to total. The following is an explanation of the expense categories from Table 2. a. Wages and Salaries For measuring the price growth of wages in the FY 2002-based RPL market basket, consistent with our proposal, we will use the ECI for wages and salaries for civilian hospital workers as the proxy for wages in the RPL market basket. The RPL market basket uses the BLS’ Employment Cost Indexes (ECIs) as proxies for wages and salaries, and benefits for civilian industry workers classified in the Standard Industrial Code (SIC) 806, Hospitals. However, beginning April 28, 2006, with the publication of March 2006 data, the ECIs will be converted from the SIC system to the North American Industrial Classification System (NAICS). The NAICS-based ECI for hospitals (NAICS 622) is similar (at least 90 percent identical) to the SIC-based ECI for hospitals. Therefore, when they are available, we will use the NAICS-based ECIs for hospitals as proxies to reflect the rate-of-price change for the wages and salaries and employee benefits cost categories in the 2002-based RPL market basket. The RPL market basket and labor-related share in this final rule will use the most recent data available from BLS. We do not expect the RPL market basket and labor-related share to change significantly when the conversion from the SIC system to the NAICS system takes place. b. Employee Benefits The FY 2002-based RPL market basket uses the ECI for employee benefits for civilian hospital workers. c. Nonmedical Professional Fees The ECI for compensation for professional and technical workers in private industry will be applied to this category since it includes occupations such as management and consulting, legal, accounting, and engineering services. d. Fuel, Oil, Coal, and Gasoline The percentage change in the price of gas fuels as measured by the PPI (Commodity Code #0552) will be applied to this component. e. Electricity The percentage change in the price of commercial electric power as measured by the PPI (Commodity Code #0542) will be applied to this component. f. Water and Sewage The percentage change in the price of water and sewage maintenance as measured by the CPI for all urban consumers (CPI Code #CUUR0000SEHG01) will be applied to this component. g. Professional Liability Insurance (PLI) The FY 2002-based RPL market basket will use the percentage change in hospital PLI premiums as estimated by the CMS Hospital Professional Liability Index for the proxy of this category. In the FY 1997-based excluded hospital with capital market basket, the same proxy was used. We continue to research options for improving our proxy for PLI. This research includes exploring various options for expanding our current survey, including the identification of another entity that will be willing to work with us to collect more complete and comprehensive data. We are also exploring other options such as third party or industry data that might assist us in creating a more precise measure of PLI premiums. At this time, we have not identified a preferred option, therefore there is no change in the proxy in this final rule. h. Pharmaceuticals The percentage change in the price of prescription drugs as measured by the PPI (PPI Code #PPI32541DRX) will be used as a proxy for this cost category. This is a special index produced by BLS as a proxy in the 1997-based excluded hospital with capital market basket. i. Food: Direct Purchases The percentage change in the price of processed foods and feeds as measured by the PPI (Commodity Code #02) will be applied to this component. j. Food: Contract Service The percentage change in the price of food purchased away from home as measured by the CPI for all urban consumers (CPI Code #CUUR0000SEFV) will be applied to this component. k. Chemicals The percentage change in the price of industrial chemical products as measured by the PPI (Commodity Code #061) will be applied to this component. While the chemicals hospitals purchase include industrial as well as other types of chemicals, the industrial chemicals component constitutes the largest proportion by far. Thus we believe that Commodity Code #061 is the appropriate proxy. l. Medical Instruments The percentage change in the price of medical and surgical instruments as measured by the PPI (Commodity Code #1562) will be applied to this component. m. Photographic Supplies The percentage change in the price of photographic supplies as measured by the PPI (Commodity Code #1542) will be applied to this component. n. Rubber and Plastics The percentage change in the price of rubber and plastic products as measured by the PPI (Commodity Code #07) will be applied to this component. o. Paper Products The percentage change in the price of converted paper and paperboard products as measured by the PPI (Commodity Code #0915) will be used. p. Apparel The percentage change in the price of apparel as measured by the PPI (Commodity Code #381) will be applied to this component. q. Machinery and Equipment The percentage change in the price of machinery and equipment as measured by the PPI (Commodity Code #11) will be applied to this component. r. Miscellaneous Products The percentage change in the price of all finished goods less food and energy as measured by the PPI (Commodity Code #SOP3500) will be applied to this component. Using this index will remove the double-counting of food and energy prices, which are captured elsewhere in the market basket. The weight for this cost category is higher, in part, than in the 1997-based index because the weight for blood and blood products (1.188) is added to it. In the 1997-based excluded hospital with capital market basket, we included a separate cost category for blood and blood products, using the BLS PPI for blood and derivatives as a price proxy. A review of recent trends in the PPI for blood and derivatives suggests that its movements may not be consistent with the trends in blood costs faced by hospitals. While this proxy did not match exactly with the products hospitals are buying, its trend over time appears to be reflective of the historical price changes of blood purchased by hospitals. However, an apparent divergence between the BLS PPI for blood and derivatives and trends in blood costs faced by hospitals over recent years led us to reevaluate whether the PPI for blood and derivatives was an appropriate measure of the changing price of blood. As discussed in the RY 2007 LTCH PPS proposed rule (71 FR 4663), we ran test market baskets classifying blood into three separate cost categories: Blood and blood products; contained within chemicals as was done for the 1992-based excluded hospital with capital market basket; and, within miscellaneous products. These categories use as proxies the following PPIs: The PPI for blood and blood products, the PPI for chemicals, and the PPI for finished goods less food and energy, respectively. Of these three proxies, the PPI for finished goods less food and energy moved most like the recent blood cost and price trends. In addition, the impact on the overall market basket by using different proxies for blood was negligible, mostly due to the relatively small weight for blood in the market basket. Therefore, we are using the PPI for finished goods less food and energy for the blood proxy because we believe it more appropriately proxies price changes (not quantities or required tests) associated with blood purchased by hospitals because it moved most like the recent blood cost and price trends. (We note that we will continue to evaluate this proxy for its appropriateness and will explore the development of alternative price indexes to proxy the price changes associated with this cost for presentation in a future proposed rule.) s. Telephone The percentage change in the price of telephone services as measured by the CPI for all urban consumers (CPI Code #CUUR0000SEED) will be applied to this component. t. Postage The percentage change in the price of postage as measured by the CPI for all urban consumers (CPI Code #CUUR0000SEEC01) will be applied to this component. u. All Other Services, Labor Intensive The percentage change in the ECI for compensation paid to service workers employed in private industry will be applied to this component. v. All Other Services, Nonlabor Intensive The percentage change in the all items component of the CPI for all urban consumers (CPI Code #CUUR0000SA0) will be applied to this component. 3. Methodology for the Capital Portion of the RPL Market Basket Unlike for the operating costs of the FY 2002-based RPL market basket, we do not have IRF, IPF, and LTCH FY 2002 Medicare cost report data for the capital cost weights, due to a change in the FY 2002 reporting requirements. Rather, as we proposed, in this final rule we used these hospitals' expenditure data for the capital cost categories of depreciation, interest, and other capital expenses for FY 2001, and age the data to a FY 2002 base year using relevant price proxies. As explained in the RY 2007 LTCH PPS proposed rule (71 FR 4663), we believe this is the best approach since these data are the most similar to the capital cost structures of those IRFs, IPFs, and LTCHs serving Medicare beneficiaries that require inpatient hospital services. As we proposed, in this final rule we calculated weights for the RPL market basket capital costs using the same set of Medicare cost reports used to develop the operating share for IRFs, IPFS, and LTCHs in order to use consistent expense data in developing the weights for both operating and capital costs. The resulting capital weight for the FY 2002 ba [Text truncated at 120,000 characters.
