SUPPLEMENTARY INFORMATION:

The final rule published on September 1, 1987 (52 FR 32992) set forth the basic procedures used under the CHAMPUS DRG-based payment system. This was subsequently amended by final rules published August 31, 1988 (53 FR 33461), October 21, 1988 (53 FR 41331), December 16, 1988 (53 FR 50515), May 30, 1990 (55 FR 21863), October 22, 1990 (55 FR 42560), and September 10, 1998 (63 FR 48439).

An explicit tenet of these final rules, and one based on the statute authorizing the use of DRGs by TRICARE, is that the TRICARE DRG-based payment system is modeled on the Medicare PPS, and that, whenever practicable, the TRICARE system will follow the same rules that apply to the Medicare PPS. The Centers for Medicare and Medicaid Services (CMS) publishes these changes annually in the Federal Register and discusses in detail the impact of the changes.

In addition, this notice updates the rates and weights in accordance with our previous final rules. The actual changes we are making, along with a description of their relationship to the Medicare PPS, are detailed below.Start Printed Page 67605

I. Medicare PPS Changes Which Affect the TRICARE DRG-Based Payment System

Following is a discussion of the changes CMS has made to the Medicare PPS that affect the TRICARE DRG-based payment system.

A. DRG Classifications

Under both the Medicare PPS and TRICARE DRG-based payment system, cases are classified into the appropriate DRG by a Grouper program. The Grouper classifies each case into a DRG on the basis of the diagnosis and procedure codes and demographic information (that is, sex, age, and discharge status). The Grouper used for the TRICARE DRG-based payment system is the same as the current Medicare Grouper with two modifications. The TRICARE system has replaced Medicare DRG 435 with two age-based DRGs (900 and 901), and has implemented thirty-four (34) neonatal DRGs in place of Medicare DRGs 385 through 390. For admissions occurring on or after October 1, 2001, DRG 435 has been replaced by DRG 523.

The TRICARE system has replaced DRG 523 with the two age-based DRGs (900 and 901). For admissions occurring on or after October 1, 1995, the CHAMPUS grouper hierarchy logic was changed so the age split (age <29 days) and assignments to MDC 15 occur before assignment of the PreMDC DRGs. This resulted in all neonate tracheostomies and organ transplants to be grouped to MDC 15 and not to DRGs 480-483 or 495. For admissions occurring on or after October 1, 1998, the CHAMPUS grouper hierarchy logic was changed to move DRG 103 to the PreMDC DRGs and to assign patients to PreMDC DRGs 480, 103 and 495 before assignment to MDC 15 DRGs and the neonatal DRGs. For admissions occurring on or after October 1, 2001, DRGs 512 and 513 were added to the PreMDC DRGs, between DRGs 480 and 103 in the TRICARE grouper hierarchy logic.

For FY 2003, CMS will implement classification changes, including surgical hierarchy changes. The TRICARE Grouper will incorporate all changes made to the Medicare Grouper.

B. Wage Index and Medicare Geographic Classification Review Board Guidelines

TRICARE will continue to use the same wage index amounts used for the Medicare PPS. In addition, TRICARE will duplicate all changes with regard to the wage index for specific hospitals that are redesignated by the Medicare Geographic Classification Review Board.

C. Hospital Market Basket

TRICARE will update the adjusted standardized amounts according to the final updated hospital market basket used for the Medicare PPS according to CMS's August 1, 2002, final rule.

D. Outlier Payments

Since TRICARE does not include capital payments in our DRG-based payments, we will use the fixed loss cost outlier threshold calculated by CMS for paying cost outliers in the absence of capital prospective payments. For FY 2003, the fixed loss cost outlier threshold is based on the sum of the applicable DRG-based payment rate plus any amounts payable for IDME plus a fixed dollar amount. Thus, for FY 2003, in order for a case to qualify for cost outlier payments, the costs must exceed the TRICARE DRG base payment rate (wage adjusted) for the DRG plus the IDME payment plus $30,707 (wage adjusted). The marginal cost factor for cost outliers continues to be 80 percent.

E. Blood Clotting Factor

For FY 2003, the updated HCPCS codes and payment rates for blood clotting factors can be found in the TRICARE Reimbursement Manual, Chapter 6, Section 4, which is accessible through the Internet at http://www.tricare.osd.mil under the sequential headings TRICARE Beneficiaries, Other Resources, TRICARE Manuals, TRICARE Reimbursement Manual. TRICARE uses the same ICD-9-CM diagnosis codes as CMS for add-on payment for blood clotting factors.

F. Indirect Medical Education (IDME) Adjustment

Passage of The Benefits Improvement and Protection Act (BIPA) of 2000, modified the transition for the IDME adjustment that was first established by the Balanced Budget Act (BBA) of 1997 and revised by the Balanced Budget Refinement Act of 1999. The formula multiplier for the TRICARE IDME adjustment has been revised to 1.02 for FY 2003 and thereafter.

G. National Operating Standard Cost as a Share of Total Costs

The FY 2003 TRICARE National Operating Standard Cost as a Share of Total Costs used in calculating the cost outlier threshold is 0.915.

II. Cost to Charge Ratio

For FY 2003, the cost-to-charge ratio used for the TRICARE DRG-based payment system will be 0.5062, which is increased to 0.5132 to account for bad debts. This shall be used to calculate the adjusted standardized amounts and to calculate cost outlier payments, except for children's hospitals. For children's hospital cost outliers, the cost-to-charge ratio used is 0.5604.

III. Updated Rates and Weights

The updated rates and weights are accessible through the Internet at http://www.tricare.osd.mil under the sequential headings TRICARE Provider Information, Rates and Reimbursements, and DRG Information. Table 1 provides the ASA rates and Table 2 provides the DRG weights to be used under the TRICARE DRG-based payment system during FY 2003 and which is a result of the changes described above. The implementing regulations for the TRICARE/CHAMPUS DRG-based payment system are in 32 CFR part 199.
