340B TPA for Tribal and Urban Indian health programs
Tribal health centers run under a 638 contract or compact and Urban Indian health centers funded through Title V of the Indian Health Care Improvement Act can join 340B as federally qualified health centers. To use 340B through outside pharmacies, a program needs a written contract with each pharmacy, each pharmacy registered in HRSA's OPAIS, and a way to keep 340B drugs away from Medicaid duplicate discounts. A 340B TPA handles the claims qualification, split billing and reporting that make those contract pharmacy arrangements work. Starting January 1, 2027, the HRSA rebate pilot applies to Indian Health Care Providers as well; Tribal and urban Indian groups have asked HRSA for an exemption.[1][3][6][7]
Which Indian health programs can join 340B
Tribal (638) health centers
Outpatient programs operated by Tribes or Tribal organizations under a contract or compact under the Indian Self-Determination Act (P.L. 93-638). They register for 340B as tribal health centers.[1][10]
Congress included outpatient programs run by Tribes or Tribal organizations under P.L. 93-638, and by Urban Indian organizations funded under Title V of the Indian Health Care Improvement Act, in the Social Security Act's definition of a federally qualified health center. That is why these programs qualify for 340B as health centers.[1][7]
Getting 340B savings through outside pharmacies
What HRSA requires
- A written contract with each pharmacy naming every pharmacy and entity location that will use 340B drugs.[3]
- Each pharmacy registered and active in 340B OPAIS before it dispenses.[3]
- Medicaid carved out at contract pharmacies unless a state arrangement is reported to HRSA.[3]
- Oversight and an independent audit of each contract pharmacy at least once a year.[3]
Where a TPA fits
- Matches pharmacy claims to your patients, prescribers and sites to decide which qualify.
- Runs split billing and replenishment so 340B inventory is reordered correctly.
- Keeps the records you need for HRSA audits, manufacturer audits and your own annual audit.
- Handles manufacturer claims data requests and 2027 rebate claims. See contract pharmacy setup with a TPA.
What the rebate pilot means for Indian Health Care Providers
HRSA's 340B Rebate Model Pilot starts January 1, 2027. For pilot drugs, covered entities, including Urban Indian organizations in 340B, pay full price upfront through their 340B wholesaler account and get a rebate from the manufacturer within a 10-day window.[4][6]
Tribal leaders have asked HRSA to exempt all Indian Health Care Providers. In its October 1, 2026 comments, TTAG pointed out that Tribal 340B providers must use their funds to carry out their agreements with the Indian Health Service, and asked for an exemption from the pilot and any permanent rebate model. NCUIH has asked for the same since December 2025.[7][8]
HRSA held a Tribal consultation on September 16, 2026, and took written comments through October 1. Until HRSA announces otherwise, plan as if the pilot applies to you.[6]
Manufacturers can only ask for HRSA's standardized claims fields in the pilot. Purchasing and encounter data aren't permitted.[4][5] Read the 340B rebate model guide.
Six steps for a Tribal or urban Indian 340B program
- Step 1
Register during an open window
Tribal and urban Indian health centers register for 340B from January 1–15, April 1–15, July 1–15 or October 1–15, and start on the first day of the next quarter. HRSA may ask a 638 program for its funding agreement instead of a grant number.[1]
- Step 2
Recertify every year
Covered entities recertify eligibility annually and must tell HRSA right away about any change in eligibility.[2]
- Step 3
Sign and register each contract pharmacy
Each pharmacy needs a written contract listing every pharmacy and entity location that will use 340B drugs, and must be active in 340B OPAIS before it dispenses. Registration uses the same quarterly windows, and your Authorizing Official has 15 days to approve it.[3]
- Step 4
Decide how you'll handle Medicaid
Contract pharmacies must carve Medicaid out unless you have an arrangement with the state Medicaid agency and report it to HRSA. Medicaid and Medicare payment for Indian Health Care Providers uses a methodology set jointly by CMS and IHS, so review this with your billing team.[3][7]
- Step 5
Audit and keep records
Oversee each contract pharmacy, audit it with an independent firm at least once a year, keep auditable records, and self-disclose any non-compliance to HRSA.[3]
