## Quick answer TRICARE is the Department of Defense’s health care program for uniformed service members, retirees, and their families worldwide. It functions as a managed care system where the government provides health benefits through a combination of military hospitals (Direct Care) and networks of civilian providers (Purchased Care) managed by regional contractors like Humana Military and TriWest.
## In detail As of May 2026, TRICARE operates under the **T-5 contract** structure, which focuses on improved access to care and enhanced digital self-service tools. The program is divided into two primary geographic regions in the United States, plus an overseas region.
### The Regional Structure * **TRICARE East:** Managed by **Humana Military**. Includes states along the Eastern seaboard, the South, and parts of the Midwest. * **TRICARE West:** Managed by **TriWest Healthcare Alliance** (which assumed operations from HNFS on January 1, 2025). Includes the Western U.S., Alaska, and Hawaii. * **TRICARE Overseas:** Managed by **International SOS**.
### Primary Plan Options TRICARE is not a one-size-fits-all plan. Beneficiaries generally choose between two main paths:
1. **TRICARE Prime:** Similar to an HMO. You are assigned a Primary Care Manager (PCM) and usually receive care at a Military Treatment Facility (MTF). Referrals are required for specialty care. Active duty service members (ADSMs) are required to enroll in Prime. 2. **TRICARE Select:** Similar to a PPO. You can see any TRICARE-authorized provider. No referrals are needed for most services, but you pay higher out-of-pocket costs (deductibles and cost-shares).
### Other Specialized Plans * **TRICARE For Life (TFL):** Wrap-around coverage for those entitled to Medicare Part A and Part B. TFL acts as the secondary payer to Medicare. * **TRICARE Reserve Select (TRS):** A premium-based plan for qualified Selected Reserve members and their families. * **TRICARE Young Adult (TYA):** For adult children who have aged out of regular TRICARE coverage (up to age 26).
### 2026 Cost Categories TRICARE costs are determined by the sponsor’s initial enlistment or appointment date: * **Group A:** Sponsor enlisted/appointed **before** January 1, 2018. * **Group B:** Sponsor enlisted/appointed **on or after** January 1, 2018.
| Feature | TRICARE Prime (Retirees) | TRICARE Select (Retirees) | | :--- | :--- | :--- | | **Annual Enrollment Fee** | ~$320–$700 (varies by Group A/B) | ~$170–$550 (varies by Group A/B) | | **Deductible** | None | $150–$300+ depending on group | | **Primary Care Visit** | ~$25–$35 | ~$35–$55 | | **Specialty Care Visit** | ~$40–$50 | ~$50–$70 |
*Note: 2026 rates are subject to annual adjustments; check TRICARE.mil for exact decimal figures based on beneficiary category.*
## Who this applies to * **Active Duty Service Members (ADSMs):** Must enroll in Prime; pay $0 out-of-pocket for all authorized medical care. * **Active Duty Family Members (ADFMs):** Can choose Prime (low cost, less flexibility) or Select (no enrollment fee, higher per-visit costs). * **National Guard/Reserve:** Eligible for TRICARE Reserve Select (TRS) while in a non-activated status. * **Retirees and Families:** Pay annual enrollment fees and cost-shares; may choose Prime or Select until reaching age 65. * **Medal of Honor Recipients:** Eligible for specific TRICARE benefits regardless of years served.
Common scenarios
**The Growing Family (Active Duty)** An E-5 Active Duty Sailor in San Diego is enrolled in TRICARE Prime. His spouse is also on Prime. When they have a baby in 2026, the entire birth at the Naval Medical Center San Diego costs the family **$0**, as Active Duty families on Prime have no cost-shares for maternity care.
**The Early Retiree (Group A)** A 48-year-old retired Army Major (enlisted in 1998, Group A) lives in Florida. He chooses TRICARE Select for the flexibility to see civilian specialists. In 2026, he pays an annual enrollment fee (roughly **$170-$180** for a single person) and must meet a **$150** deductible before TRICARE begins paying for his non-preventive visits.
**The Reservist** A Marine Corps Reservist qualifies for TRICARE Reserve Select. In 2026, he pays a monthly premium (e.g., **~$50** for individual coverage) to have PPO-style health insurance that he can use with his local family doctor.
