## Quick answer TRICARE provides comprehensive health coverage across all 50 U.S. states through two primary geographic regions: **East** and **West**. Coverage is managed by Humana Military in the East and TriWest Healthcare Alliance in the West, ensuring that military families have access to care whether they are stationed at a major installation or living in a remote civilian community.

In detail

As of May 21, 2026, the TRICARE landscape in the United States is divided into two distinct administrative regions. While the underlying benefits (like pharmacy and dental) are standard across the country, your regional contractor determines your provider network and customer service.

### The Two-Region Map The United States is split roughly down the middle, with a transition that occurred in 2025 under the T-5 contract series:

* **TRICARE East (Humana Military):** Covers Alabama, Arkansas, Connecticut, Delaware, the District of Columbia, Florida, Georgia, Illinois, Indiana, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Mississippi, Missouri (St. Louis area), New Hampshire, New Jersey, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas (only the eastern/central portions), Vermont, Virginia, West Virginia, and Wisconsin. * **TRICARE West (TriWest Healthcare Alliance):** Covers Alaska, Arizona, California, Colorado, Hawaii, Idaho, Iowa, Kansas, Minnesota, Missouri (except St. Louis), Montana, Nebraska, Nevada, New Mexico, North Dakota, Oregon, South Dakota, Texas (western areas/El Paso), Utah, Washington, and Wyoming.

### Portability Across States One of TRICARE's strongest features is "portability." Because the program covers all states: * **Permanent Change of Station (PCS):** When you move between states, you must update your address in DEERS. If you move across a regional boundary (e.g., Virginia to California), you must transfer your enrollment from Humana Military to TriWest. * **Traveling:** TRICARE Prime users must coordinate urgent care outside their home state to avoid "Point of Service" charges. TRICARE Select users can generally see any TRICARE-authorized provider in any state. * **Pharmacy:** Express Scripts manages the pharmacy benefit nationwide. Whether you are in Maine or Alaska, your copays for mail-order or retail network pharmacies remain the same.

### 2026 Costs and Coverage Types Costs are standardized by "Group" (Group A joined before Jan 1, 2018; Group B joined after) rather than by state.

*Note: For 2026, Group A Retirees on TRICARE Select pay an annual enrollment fee of approximately $180 (individual) or $360 (family). Check TRICARE.mil for the most precise 2026 figures based on your specific beneficiary category.*

## Who this applies to * **Active Duty Service Members:** Assigned to a specific region based on their duty station; must use Prime. * **Active Duty Families:** Can choose between Prime or Select in any state. * **National Guard and Reserve:** Eligible for TRICARE Reserve Select (TRS) regardless of which state they reside in. * **Retirees:** Can use TRICARE Select or Prime (if in a PSA) until age 65, across all regions. * **Medicare-Eligible Retirees:** Covered by TRICARE For Life (TFL) in all states, acting as secondary payer to Medicare.

Common scenarios

**The Cross-Country Move** Sgt. Miller moves from Fort Liberty, NC (East Region) to Fort Irwin, CA (West Region) in May 2026. He updates DEERS immediately. Because he is moving between regions, his coverage doesn't "break," but he must contact TriWest Healthcare Alliance to officially transfer his Prime enrollment from Humana Military to ensure his new Primary Care Manager (PCM) is assigned correctly.

**The Traveling Retiree** A retired Navy Commander living in Florida (East) trips and breaks his arm while visiting the Grand Canyon in Arizona (West) in 2026. Because he is on TRICARE Select, he simply finds a local TRICARE-authorized urgent care center in Arizona. He pays his standard 2026 Group A retiree copay (approx. $35–$40), and the claim is processed by TriWest even though his home region is Humana.

**The Remote Reservist** An Army Reservist lives in a rural part of Montana where there are no military bases. She enrolls in TRICARE Reserve Select (TRS). Because TRS is available in all states and doesn't require living near a base, she sees a local civilian doctor. In 2026, her monthly premium is roughly $55–$60 for individual coverage.

## Related terms * **DEERS:** The Defense Enrollment Eligibility Reporting System; the master database that tracks your address and eligibility. * **Prime Service Area (PSA):** Geographic areas (usually near bases) where TRICARE Prime is fully supported. * **T-5 Contract:** The fifth generation of TRICARE contracts which transitioned the West region to TriWest in 2025. * **Point of Service (POS):** An extra fee charged when Prime members see a doctor without a referral, regardless of which state they are in. * **Reciprocity:** The ability for a beneficiary from one region to receive care in another region.
