SUPPLEMENTARY INFORMATION:

The final rule published on September 1, 1987 (52 FR 32993) 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 60113

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

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

A. DRG Classifications

Under both the Medicare PPS and the 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 is 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 For admissions occurring on or after October 1, 2001, DRG 435 has been replaced by DRG 523.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 admissions occurring on or after October 1, 2004, DRG 483 was deleted and replaced with DRGs 541 and 542, splitting the assignment of cases on the basis of the performance of a major operating room procedure. The description for DRG 480 was changed to “Liver Transplant and/or Intestinal Transplant” and the description for DRG 103 was changed to “Heart/Heart Lung Transplant or Implant of Heart Assist System”. For FY 2007, CMS will implement classification changes, including surgical hierarchy changes. The TRICARE Grouper will incorporate all changes made to the Medicare Grouper, with the exception of the pre-surgical hierarchy changes, which will remain the same as FY 2006.

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. TRICARE will also duplicate all changes with regard to the wage index for specific hospitals that are redesignated by the Medicare Geographic Classification Review Board. In addition, TRICARE will continue to utilize the out commuting wage index adjustment.

C. Revision of the Labor-Related Share of the Wage Index

TRICARE is adopting CMS' percentage of labor related share of the standardized amount. For wage index values greater than 1.0, the labor related portion of the ASA shall equal 69.7 percent. For wage index values less than or equal to 1.0 the labor related portion of the ASA shall continue to equal 62 percent.

D. Hospital Market Basket

TRICARE will update the adjusted standardized amounts according to the final updated hospital market basket used for the Medicare PPS for all hospitals subject to the TRICARE DRG-based payment system according to CMS' August 18, 2006, final rule.

E. Outlier Payments

Since TRICARE does not include capital payments in our DRG-based payments (TRICARE reimburses hospitals for their capital costs as reported annually to the contractor on a pass through basis), 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 2007, 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 2007, 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 $22,639 (wage adjusted). The marginal cost factor for cost outliers continues to be 80 percent.

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

The FY 2007 TRICARE National Operating Standard Cost as a Share of Total Costs (NOSCASTC) used in calculating the cost outlier threshold is 0.925. TRICARE uses the same methodology as CMS for calculating the NOSCASTC, however, the variables are different because TRICARE uses national cost to charge ratios while CMS uses hospital specific cost to charge ratios.

G. Indirect Medical Education (IDME) Adjustment

Passage of the MMA of 2003 modified the formula multipliers to be used in the calculation of the indirect medical education IDME adjustment factor. Since the IDME formula used by TRICARE does not include disproportionate share hospitals (DSHs), the variables in the formula are different than Medicare's, however; the percentage reductions that will be applied to Medicare's formula will also be applied to the TRICARE IDME formula. The new multiplier for the IDME adjustment factor for TRICARE for FY 2007 is 1.00.

H. Expansion of the Post Acute Care Transfer Policy

For FY 2007 TRICARE is adopting CMS' expanded post acute care transfer policy according to CMS' final rule published August 18, 2006.

I. Blood Clotting Factor

For FY 2007, TRICARE is adopting CMS' payment methodology for blood clotting factor according to CMS' final rule published August 18, 2006.

II. Cost to Charge Ratio

While CMS uses hospital-specific cost to charge ratios, TRICARE uses a national cost to charge ratio. For FY 2007, the cost-to-charge ratio used for the TRICARE DRG-based payment system for acute care hospitals and neonates will be 0.3897 which is increased to 0.3967 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 0.4282.

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 2007 and which is a result of the changes described above. The implementing regulations for the Start Printed Page 60114TRICARE/CHAMPUS DRG-based payment system are in 32 CFR part 199.
