## Quick answer Texas is located in the **TRICARE East Region**, managed by Humana Military. All mail-in correspondence, claims, and inquiries for Texas-based beneficiaries should be directed to the East Region addresses in Kentucky and Wisconsin, while pharmacy-related items go to Express Scripts in Missouri.

In detail

Texas is a critical state for military healthcare, home to major installations like Fort Cavazos and Joint Base San Antonio. As part of the **East Region**, Texas beneficiaries fall under the T-5 contract managed by Humana Military.

Whether you are updating your address or mailing a paper claim, using the correct address is vital to prevent delays in care or reimbursement.

### Claims and Correspondence Addresses For medical claims and general inquiries for beneficiaries living in Texas:

* **Medical Claims (East Region):** TRICARE East Region Claims Processing P.O. Box 7981 Madison, WI 53707-7981 * **General Correspondence:** Humana Military P.O. Box 740062 Louisville, KY 40201-7462 * **Grievances and Appeals:** Humana Military Grievances/Appeals P.O. Box 740044 Louisville, KY 40201-7444

### Pharmacy Addresses (Express Scripts) Regardless of region, all Texas beneficiaries use Express Scripts for pharmacy home delivery and claims:

### Update Your Physical Address (DEERS) Technically, you do not "mail" a change of address to TRICARE. You must update your address in the **Defense Enrollment Eligibility Reporting System (DEERS)**. If your Texas address is not current in DEERS, your claims will be denied.

* **Online:** Visit the [milConnect website](https://milconnect.dmdc.osd.mil/). * **In Person:** Visit a Texas RAPIDS ID Card Office (found at most major bases like Lackland AFB, Fort Bliss, or NAS Corpus Christi). * **Mail:** Defense Manpower Data Center Support Office Attn: COA 400 Gigling Road Seaside, CA 93955-6771

## Who this applies to * **Active Duty Families in Texas:** Those stationed at Texas installations must ensure their Texas residential address is in DEERS to maintain TRICARE Prime or Prime Remote eligibility. * **Retirees in Texas:** Those using TRICARE Select must have a Texas address on file to ensure they are billed correctly under the East Region rate structure. * **TRICARE Reserve Select (TRS) Members:** Traditional Drilling Guardsmen (Texas State Guard/National Guard) and Reservists must update their address to ensure they receive monthly premium invoices. * **Providers:** Texas-based doctors and specialists must mail paper claims to the Madison, WI address listed above.

Common scenarios

### Scenario 1: Moving to Fort Bliss (El Paso) An Army family moves from Colorado (West Region) to Fort Bliss, TX (East Region). Because they changed regions, they must not only update DEERS but also contact **Humana Military** to enroll in the East Region. If they fail to update their Texas address by June 2026, their Colorado-based Prime enrollment may lapse, resulting in out-of-network costs.

### Scenario 2: Filing a Paper Claim in Dallas A retiree visits a non-network specialist in Dallas and pays out of pocket. To get reimbursed, they must mail DD Form 2642 to the Wisconsin East Region claims address. For 2026, if they are a Group A retiree, they must ensure they have met their annual deductible (varies by year; check TRICARE.mil) before reimbursement kicks in.
