## Quick answer To contact TRICARE, you must reach out to the specific contractor managing your region (Humana Military for the East, TriWest for the West) or the specific benefit manager for pharmacy or dental needs. There is no single "concierge" number; your point of contact depends entirely on your geographic location and the type of care you are seeking.

In detail

TRICARE is managed through regional contracts (known as T-5). Effective January 1, 2025, and continuing through 2026, the United States is divided into two regions. Your first step in contacting TRICARE is identifying your region.

### DEERS (Eligibility Status) If your contact issue is related to eligibility, marriage, birth of a child, or address updates, you must contact **DEERS** (Defense Enrollment Eligibility Reporting System), not the regional contractor. * **Phone:** 1-800-538-9552 * **Website:** milConnect (milconnect.dmdc.osd.mil)

## Who this applies to * **Active Duty Service Members (ADSMs):** Must coordinate primarily through their military clinic but use regional contractors for civilian referrals. * **Active Duty Family Members (ADFMs):** Use regional contractors for Prime or Select management and Express Scripts for medications. * **Retirees and their Families:** Use regional contractors for enrollment and annual fee payments (e.g., TRICARE Select enrollment fees). * **National Guard and Reserve:** Contact contractors to initiate TRICARE Reserve Select (TRS) or TRICARE Retired Reserve (TRR) coverage.

Common scenarios

**Scenario 1: Billing Dispute in the West Region** John, a retiree in Arizona (West Region), receives a surprise bill for an urgent care visit in 2026. He believes his copay should only be $38 (2026 TRICARE Select Group A rate). He must contact **TriWest Healthcare Alliance** at 1-888-874-9378 to file a claims appeal.

**Scenario 2: Moving from Virginia to California** Sarah is moving from Virginia (East) to California (West). She cannot simply call Humana Military to "transfer" her care. She must update her address in **DEERS** first, then contact **TriWest** to enroll in her new region and select a new PCM.

**Scenario 3: Prescription Refills** Mark needs to transition a maintenance medication to home delivery to save on 2026 pharmacy copays ($17 for a 90-day supply of generic). He should contact **Express Scripts** at 1-877-363-1303 or use the Express Scripts mobile app.

## Related terms * **DEERS (Defense Enrollment Eligibility Reporting System):** The global database of service members and dependents used to verify TRICARE eligibility. * **T-5 Contract:** The fifth generation of TRICARE contracts, which moved the West Region to TriWest in 2025. * **PCM (Primary Care Manager):** The doctor or clinic responsible for your basic care and referrals. * **Network Provider:** A civilian doctor who has a contract with Humana Military or TriWest to provide care at discounted rates. * **Express Scripts:** The private company contracted to manage the TRICARE pharmacy benefit.
