TRICARE Contact Information: 2026 Phone Numbers & Links

*TRICARE.com is an independent reference site and is not affiliated with the official TRICARE program or the Department of Defense. For official policy and member portals, visit TRICARE.mil.*

## Quick answer To contact TRICARE, you must reach out to the specific contractor that manages your region or benefit. There is no single "TRICARE phone number" for everyone; instead, you contact Humana Military (East), TriWest (West), International SOS (Overseas), or Express Scripts (Pharmacy).

In detail

Because TRICARE is managed by private contractors under the Defense Health Agency (DHA), your point of contact depends entirely on where you live and what type of help you need. As of June 1, 2026, the following contact information is current for the T-5 contract cycle.

### Regional Contractors (Medical Care & Enrollment) Contact your regional contractor for enrollment, finding a provider, primary care manager (PCM) changes, and claims status.

### Specialized Benefit Contractors Regardless of your region, these contractors manage specific portions of your 2026 coverage:

### DEERS (Eligibility and ID Cards) To update your address, add a dependent, or verify eligibility, you must contact the Defense Enrollment Eligibility Reporting System (DEERS). * **Phone:** 1-800-538-9552 (DMDC/DEERS Support Office) * **Online:** milConnect (milconnect.dmdc.osd.mil)

## Who this applies to * **Active Duty Service Members:** Must contact their PCM or Regional Contractor for referrals to avoid out-of-pocket costs. * **Retirees and Families:** Contact regional contractors for TRICARE Select or Prime enrollment and to track 2026 catastrophic caps. * **TRICARE Reserve Select (TRS) Members:** Contact regional contractors to set up premium payments and verify initial enrollment. * **Pharmacy Users:** Contact Express Scripts for home delivery tracking or to check if a medication is on the 2026 formulary.

Common scenarios

**Scenario 1: Moving from Virginia to California** An Army family moves from the East Region (Humana Military) to the West Region (TriWest) in June 2026. They must contact TriWest at 1-888-874-9378 to update their enrollment and select a new Primary Care Manager. They do not need to contact Humana to "cancel"; the enrollment transfer handles the transition.

**Scenario 2: Missing Pharmacy Delivery** A retiree in Florida is waiting for a 90-day supply of maintenance medication. Because pharmacy is a national benefit, they do not call Humana Military. Instead, they call Express Scripts at 1-877-363-1303 to track the package or report a missing shipment.

**Scenario 3: Verifying a Medical Claim** A TRICARE Select enrollee sees a specialist in Arizona and receives a bill for $40. To verify if this aligns with the 2026 copayment schedule, they log into the TriWest secure portal or call TriWest directly to review their Explanation of Benefits (EOB).
