IHS/THP/UIO Reimbursement Agreements Program–Information for Providers

The VA Indian Health Services/Tribal Health Programs/Urban Indian Organization (I/T/U) Reimbursement Agreements Program (RAP) provides VA reimbursement to IHS, THP and UIO health facilities for services provided to eligible American Indian (AI) and Alaska Native (AN) Veterans.

Eligible AI and AN Veterans do not need VA preauthorization to receive health care services at IHS, THP and UIO health facilities. In Alaska, non-native Veterans can also access services with VA preauthorization.

NOTE: This video has not been updated to reflect UIO inclusions.

The agreements program was first initiated in 2012 with IHS/THP and in 2022 expanded to include Urban Indian Organization (UIO). The program is part of a larger effort to improve access to care and coordination for our nation’s AI and AN Veterans under a broader VA-IHS Memorandum of Understanding managed by VHA.

Listed below are several resources for initiating agreements and implementing the reimbursement agreement.

On this Page:

Eligibility and Enrollment Verification

Eligibility and Enrollment Verification explains how I/T/U facilities can verify American Indian/Alaska Native (AI/AN) Veteran eligibility.

Initiation and Implementation

I/T/U Initiation and Implementation outlines the process for starting and implementing the I/T/U reimbursement agreement. Through the agreement process, VA encourages I/T/U facility staff to enroll eligible Veterans for care at VA.

Submitting Claims

I/T/U facility staff may submit claims electronically or on paper:

Pharmacy Claims

VA will only reimburse IHS/THP/UIO for pharmaceutical drugs listed on VA National Formulary.

VA accepts paper and EDI pharmacy claims and follows the same claim submission process as IHS/THP. UIO must be annotated in the EDI and paper claims. Refer to the Pharmacy Claims Submission Guide for information on how to submit pharmacy claims.

Electronic billing (Electronic Data Interchange)

Facilities submitting Electronic Data Interchange (EDI) claims need to register with Change Healthcare by phone or online.

Once registered, billing staff should ensure “IHS, THP or UIO” is added to the SBR03 segment of the 837 for proper routing. VA payer IDs are:

  • 12115 for medical claim submissions
  • 12116 for dental claims
  • 00231 for any inquiry transaction

Paper Claims

Change Healthcare Customer Support:
8 a.m.–4 p.m. Central Time

Change Healthcare Customer Resources–Payer Lists

VA has a centralized claims processing center for paper claims. Send paper claims to:

VHA Office of Integrated Veteran Care
P.O. Box 30780, Tampa FL 33630-3780


Third Party Billing

IHS/THP/UIO will bill all third-party payers before billing VA. VA will be responsible for the remaining balance. I/T/U providers are responsible for submitting health care claims to other health insurance before billing VA. VA does not reimburse copayments, deductibles or participate in balance billing. VA will not pay for services covered by Medicare/Medicaid.

Coronavirus-related Billing

The 2020 VA IHS/THP Reimbursement Agreements Modification will allow VA pay for direct care or Purchased Referred Care (PRC) related to COVID-19 healthcare services as defined in the section 11.5. Other PRC services are not reimbursable, as healthcare services must be provided directly by your facility per the agreement.

For VA to pay for direct care or PRC treatment due to COVID-19, the diagnosis and CPT code must follow Medicare guidance for COVID-19 billing, and must be identified as COVID-19 in the claims. Outpatient or inpatient claims submissions must follow industry standard guidelines. Current VA billing process or requirements is not changing except for use of COVID-19 specific codes. Refer to the Medicare & Coronavirus webpage for further information.

Care Coordination

When eligible AI/AN Veteran care is not available at participating I/T/U RAP facilities, care must be referred to non-I/T/U providers. This includes referrals to VA health care facilities where VA may provide the care directly or refer to a community care provider.

To ensure enhanced care coordination, VA established the Healthcare Coordination Advisory Board (HCAB) with participation from IHS and Tribes, to assist VA in developing standardized processes for care coordination. In 2020, VA adopted a multifaceted approach leveraging VA’s Care Coordination Request for Services (RFS) process, a standardized process to receive requests for care form community providers.

More details on how to refer care to VA and the RFS process, as well as local point of contacts, can be found on the VA Request and Coordinate Care page. Participating I/T/U Facilities with additional questions can also contact the RAP team for assistance.

Native Cultural Awareness

Cultural awareness is an essential component of Veteran-centered care. Providers who do not regularly work with AI/AN patients may lack awareness of specific cultural aspects of care. To boost cultural awareness of this group, VA has identified material that could benefit both clinical and administrative staff. They are:

  • SAMHSA Native Culture Card–a guide to build cultural awareness; it is intended to serve as a general briefing to enhance cultural competence while providing services to American Indian and Alaska Native communities.
  • IHS Gold Book–a four-part publication in which IHS reviews progress from the agency’s first 50 years of operation, including lessons learned regarding culturally acceptable public health services.

Operational Updates

The Department of Veteran Affairs (VA) is pleased to announce the release of the new VA-IHS national Reimbursement Agreement regarding reimbursement for health care services provided by IHS to eligible American Indian and Alaska Native Veterans. The new agreement builds upon the current Reimbursement Agreement for Direct Care services by expanding the scope of reimbursements to include Purchased/Referred Care (PRC) and contracted travel. The new agreement also removes some limitations on the scope of Direct Care services eligible for VA reimbursement.

The national agreement covers all currently participating IHS facilities and no action is needed by IHS facilities currently. For details, please see the Tribal Leader Letter issued on December 6, 2023. VA is still negotiating with Tribal Health Program (THP) stakeholders and hopes to announce new agreements to cover THP facilities soon.
