## Quick answer In California, TRICARE coverage is managed by **TriWest Healthcare Alliance** as part of the West Region. Beneficiaries have access to world-class military hospitals (like Naval Medical Center San Diego) and an extensive network of civilian providers under plans like TRICARE Prime, Select, and For Life.
In detail
California is the cornerstone of the TRICARE West Region. Following the transition to the T-5 contract on January 1, 2025, **TriWest Healthcare Alliance** serves as the regional contractor, overseeing the provider network and claims processing for the state.
Coverage Options in California
1. **TRICARE Prime:** This is a managed care option similar to an HMO. In California, Prime is heavily concentrated around "Prime Service Areas" (PSAs), which are usually within 40 miles of a military base. You are assigned a Primary Care Manager (PCM), typically at a Military Treatment Facility (MTF). 2. **TRICARE Select:** A preferred provider organization (PPO) model. It offers the most flexibility, allowing you to see any TRICARE-authorized provider. In California’s high-cost medical markets (like the Bay Area or Los Angeles), Select is popular for those who want to avoid the referral requirements of Prime. 3. **TRICARE For Life (TFL):** For retirees age 65+ with Medicare Parts A and B. TFL acts as secondary payer to Medicare across California. 4. **TRICARE Reserve Select (TRS):** Available to qualified members of the Selected Reserve and their families.
### Major Military Treatment Facilities (MTFs) California hosts some of the largest medical hubs in the military health system: * **Naval Medical Center San Diego (Balboa):** A major teaching hospital and trauma center. * **Naval Hospital Camp Pendleton:** Serving the Marine Corps community in North County San Diego. * **David Grant USAF Medical Center (Travis AFB):** The largest Air Force medical center in the United States, located in Fairfield. * **Weed Army Community Hospital:** Serving the National Training Center at Fort Irwin.
### 2026 Costs and Fees Costs depend on the sponsor's "Group" status (Group A joined before 2018; Group B joined on/after Jan 1, 2018). * **Active Duty Family Members (Prime):** Generally $0 out-of-pocket for covered services at MTFs or with referrals. * **Retirees (Select - Group A):** For 2026, the annual enrollment fee is approximately $391.92 per individual or $783.84 per family (varies slightly by plan year—always check TRICARE.mil). * **Catastrophic Cap:** This is the most you will pay out of pocket in a year. In 2026, for Group A retirees, it is typically around $4,399.
### Provider Network in CA California has a robust "Prime Service Area" network. If you live in a rural area (e.g., the Sierra Nevadas or the far North Coast), you may be eligible for **TRICARE Prime Remote**, which allows you to receive Prime benefits without living near a military installation.
## Who this applies to * **Active Duty Service Members (ADSMs):** Stationed at bases like Camp Pendleton, Travis AFB, or NTC Fort Irwin. Must enroll in Prime. * **Active Duty Family Members (ADFMs):** Can choose between Prime (lower cost) or Select (more flexibility). * **Retirees and their Families:** Residing in California; can use Select, Prime (if in a PSA), or TFL. * **National Guard and Reserve:** Thousands of California-based Guardsmen use TRICARE Reserve Select (TRS) while in a drill status.
