## Quick answer Military bases serve as the primary hubs for TRICARE healthcare delivery through Military Medical Treatment Facilities (MTFs). Depending on your base and plan type, you may receive all your care on-station for $0 out-of-pocket, or you may be referred to civilian providers in the surrounding "TRICARE Prime Service Area" (PSA).

## In detail Military bases are the foundation of the TRICARE system. Every base with a medical clinic or hospital creates a **Prime Service Area (PSA)**—a geographic zone (usually within a 40-mile radius or one-hour drive) where TRICARE Prime is offered and managed.

### Military Medical Treatment Facilities (MTFs) MTFs are the clinics and hospitals located directly on military installations. They are categorized into three levels: 1. **Military Medical Centers:** Large teaching hospitals (e.g., Walter Reed, Brooke Army Medical Center) that offer specialized surgeries and inpatient care. 2. **Military Community Hospitals:** Mid-sized facilities providing inpatient and outpatient services. 3. **Clinics:** Smaller facilities primarily providing primary care and outpatient services.

### Priority of Care at the Base Base facilities operate on a priority system. Space is not guaranteed for everyone: * **Active Duty Service Members (ADSMs):** Priority 1. They must receive care at the MTF unless referred out. * **Active Duty Family Members (ADFMs) enrolled in Prime:** Priority 2. They have the next claim to available appointments. * **Retirees and their families enrolled in Prime:** Priority 3. * **TRICARE Select users:** Seen only on a "space-available" basis, which is increasingly rare at busy bases.

### The Role of Regional Contractors While the base provides the doctors, two private contractors manage the network of civilian doctors surrounding the base: * **East Region:** Humana Military. * **West Region:** TriWest Healthcare Alliance (as of the T-5 contract started Jan 1, 2025).

### Costs for Base-Centered Care (2026 Rates) If you are enrolled in **TRICARE Prime** and receive care at the MTF on base: * **Enrollment Fees:** $0 for Active Duty and their families. For Retirees (Group A), the 2026 rate varies by plan year — check TRICARE.mil for current rates (historically ~$363/individual). * **Copayments:** $0 for all care received at the MTF. * **Pharmacy:** $0 for prescriptions filled at the base pharmacy (even for TRICARE Select users).

## Who this applies to * **Active Duty Service Members:** Required to use the base MTF as their primary medical home. * **Active Duty Families:** Can choose Prime (base-centered) or Select (civilian-centered). Choosing Prime usually means the base clinic is your Primary Care Manager (PCM). * **Retirees under 65:** May live near a base to maintain TRICARE Prime access and $0 copays at the MTF. * **TRICARE For Life (TFL) Users:** While TFL uses Medicare, retirees over 65 can still use base pharmacies to avoid the $10–$90 copays associated with Express Scripts home delivery or retail.

Common scenarios

### Scenario 1: The Prime Family on Base An Active Duty family (Group A) is stationed at Fort Cavazos. They are enrolled in **TRICARE Prime**. The mother and children see a military pediatrician and GP on base. Their out-of-pocket cost for all office visits and medications in 2026 is **$0**.

### Scenario 2: The Select User and the Base Pharmacy A retired Navy Commander lives 10 miles from NAS Pensacola but uses **TRICARE Select** because he prefers a civilian specialist off-base. He pays a copay for his doctor visits (e.g., ~$38 for a 2026 specialist visit), but he drives onto the base to use the MTF pharmacy. By doing so, he pays **$0** for his maintenance medications instead of the $10+ retail copay.

### Scenario 3: Living Outside the "Base" Radius A Reservist lives 100 miles from the nearest military installation. Because they are not within a Prime Service Area (the 40-mile radius around a base), they generally cannot enroll in TRICARE Prime and must use **TRICARE Select** or **TRICARE Reserve Select (TRS)**, seeing civilian providers in their local community.

## Related terms * **PCM (Primary Care Manager):** The specific doctor or clinic at the base assigned to handle your routine care. * **MTF (Military Medical Treatment Facility):** Any clinic or hospital located on a military base. * **PSA (Prime Service Area):** The geographic area around a base where Prime enrollment is available. * **Space-Available Care:** Medical care provided to non-Prime beneficiaries at an MTF only when the facility has extra capacity. * **T-5 Contract:** The current TRICARE contract (effective 2025) that transitioned the West Region to TriWest Healthcare Alliance.
