## Quick answer Military bases serve as the primary hubs for healthcare delivery through Military Hospitals and Clinics. Depending on your TRICARE plan, the base is either your mandatory point of care (TRICARE Prime) or an optional resource for pharmacy services and space-available appointments (TRICARE Select).

## In detail Military bases house Military Treatment Facilities (MTFs). These facilities range from small clinics providing primary care to large medical centers like Brooke Army Medical Center or Walter Reed. Your relationship with the base depends entirely on your location and your chosen TRICARE plan.

### The Role of the Base by TRICARE Plan * **TRICARE Prime:** If you live in a Prime Service Area (PSA)—usually within 40 miles of a base—you are typically required to enroll at the base MTF. The base acts as your "medical home," where you are assigned a Primary Care Manager (PCM). * **TRICARE Select:** You are not required to use the base for primary care. You can see any TRICARE-authorized provider. However, you can still use the base for "space-available" care and pharmacy services. * **TRICARE For Life (TFL):** Medicare-wraparound coverage allows you to use the base on a space-available basis, though most TFL beneficiaries use civilian providers.

### Military Hospitals vs. Clinics * **Clinics:** Typically found on smaller bases; focus on primary care, pediatrics, and family medicine. * **Hospitals/Medical Centers:** Found on major installations; offer specialized surgery, intensive care, and specialized departments (e.g., oncology, cardiology).

### Regional Contractors and Your Base As of 2026, TRICARE is divided into two regions that manage the network of civilian providers surrounding military bases: * **East Region:** Managed by **Humana Military**. * **West Region:** Managed by **TriWest Healthcare Alliance** (under the T-5 contract).

If the base hospital cannot provide a specific service, the MTF referral office will coordinate with these contractors to send you to a local civilian specialist.

### 2026 Costs at the Base One of the primary benefits of using a military base for healthcare is the cost: * **Active Duty Service Members (ADSMs):** $0 out-of-pocket for all care at the base. * **Active Duty Family Members (ADFMs) on Prime:** $0 copays for care received at the base. * **Retirees/Others:** Usually $0 copays for care at the base MTF, though small subsistence charges may apply for inpatient stays. * **Pharmacy:** $0 copays for prescriptions filled at a military base pharmacy (for all eligible beneficiaries).

## Who this applies to * **Active Duty Service Members:** Mandatory use of base facilities for all medical needs unless referred out. * **Active Duty Family Members:** Priority access to base clinics if enrolled in TRICARE Prime. * **Retirees and their Families:** Lower priority for appointments (space-available) but full access to base pharmacies. * **TRICARE Reserve Select (TRS) / Retired Reserve (TRRR):** Primarily use civilian networks but can use base pharmacies and space-available care.

Common scenarios

**Scenario 1: Prime Enrollment near Fort Cavazos (2026)** An active duty spouse lives 5 miles from Fort Cavazos. Because she is in a Prime Service Area, she is enrolled in **TRICARE Prime** with a PCM at the base clinic. Her copay for an annual physical at the base is **$0**. If she needs a specialist the base doesn't have, the MTF issues a referral to a civilian doctor via TriWest.

**Scenario 2: Select User and the Base Pharmacy** A retired Navy Commander in Florida uses **TRICARE Select**. She sees a civilian doctor in the Humana Military network (paying a 2026 copay of roughly $38 per visit). However, she takes her maintenance prescription to the nearby Naval Air Station Jacksonville pharmacy. By using the base instead of a retail pharmacy or home delivery, her cost is **$0**.

**Scenario 3: Space-Available Care** A TRICARE For Life beneficiary lives near Wright-Patterson AFB. He needs a routine dermatology check. He calls the base appointment line. Since active duty and Prime members have priority, he is told there are no openings for three weeks. He chooses to see a Medicare-participating civilian dermatologist instead to get seen sooner.

## Related terms * **MTF (Military Treatment Facility):** Any clinic or hospital located on a military installation. * **PCM (Primary Care Manager):** The specific doctor or team at the base responsible for your primary care. * **PSA (Prime Service Area):** Areas (usually near bases) where TRICARE Prime is offered and MTF enrollment is common. * **Space-Available Care:** Appointments offered to non-Prime retirees or family members only after all Prime members have been scheduled. * **T-5 Contract:** The current TRICARE contract (effective 2025) that defined the current East/West regional boundaries.
