## TRICARE in Wyoming Wyoming falls under the TRICARE West Region jurisdiction. As of 2026, TriWest Healthcare Alliance is the active contractor, having replaced Health Net Federal Services (HNFS). Beneficiaries in Wyoming, particularly those near F.E. Warren AFB, rely on a mix of on-base Military Treatment Facilities (MTFs) and an extensive civilian network in Cheyenne and the surrounding Laramie County area.

## Major military installations While Wyoming is a large state by landmass, its military footprint is centered primarily in the southeast corner and through the National Guard.

## Plans available in Wyoming Residents of Wyoming have access to the following TRICARE plans, depending on their service status and location:

## Finding care in Wyoming For those stationed at **F.E. Warren AFB**, most primary care is managed through the **90th Medical Group**. However, if you are on TRICARE Select or if the base clinic cannot accommodate a specialty referral, you will use the TriWest provider directory.

* **Provider Directory:** Visit the TriWest Healthcare Alliance website to search for "Network" providers in cities like Cheyenne, Laramie, and Casper to ensure lower out-of-pocket costs. * **Network vs. Non-Network:** In Wyoming’s rural areas, you may encounter non-network providers. While you can see them under TRICARE Select, you may be required to pay upfront and file your own claims. * **Telehealth:** Given Wyoming's rural nature, TRICARE covers many telehealth services. Under the current T-5 contract, TriWest offers various virtual health options for behavioral health and urgent care to bridge the gap between rural towns and major medical hubs.

Common questions for Wyoming beneficiaries

**I am PCSing to F.E. Warren AFB. When should I switch regions?** You should update your address in DEERS as soon as you arrive in Wyoming. Because Wyoming is in the West Region, if you are moving from the East (e.g., Florida or North Carolina), you must contact TriWest Healthcare Alliance to enroll in your new plan. If you are moving from another West state, you simply need to update your primary care manager (PCM) location.

**Can I use the UCHealth system in Colorado while living in Wyoming?** Yes. Many Wyoming residents near Cheyenne utilize the UCHealth or Banner Health systems in Northern Colorado (Fort Collins/Greeley) for specialty care. Since both states are in the West Region, your TriWest authorization for specialty care will often cover these out-of-state network facilities.

**Does TRICARE work with Wyoming Medicaid?** By law, TRICARE is the secondary payer to most other health insurance plans, but it is the primary payer to Medicaid. If you have both, your providers should bill TRICARE first.
