## Quick answer In the context of the U.S. military, "Health Insurance" refers to **TRICARE**, the Department of Defense’s health care program for uniformed service members, retirees, and their families. It provides comprehensive medical coverage, including preventative care, specialty services, and prescriptions, through a combination of military hospitals and private civilian networks.

## In detail TRICARE is one of the most robust health insurance systems in the world, managed by the Defense Health Agency (DHA). For 2026, the program is divided into two primary geographic regions in the United States: the **East Region** (managed by Humana Military) and the **West Region** (managed by TriWest Healthcare Alliance).

### Primary TRICARE Plan Types While there are several niche programs, most beneficiaries fall into one of these three categories:

* **TRICARE Prime:** Similar to an HMO. You have a Primary Care Manager (PCM) who coordinates all care. Active Duty Service Members (ADSMs) must enroll in Prime and have $0 out-of-pocket costs. * **TRICARE Select:** Similar to a PPO. You can see any TRICARE-authorized provider without a referral. This plan offers more flexibility but requires annual deductibles and cost-shares. * **TRICARE For Life (TFL):** Wrap-around coverage for those eligible for both Medicare and TRICARE. TFL acts as secondary payer to Medicare.

### 2026 Cost Summary (Group A Beneficiaries) *Note: Group A includes those whose initial enlistment or appointment was before Jan. 1, 2018.*

### Regional Management As of 2026, the T-5 contract is in full effect. * **East Region:** Humana Military handles claims and provider networks for states ranging from the East Coast to the Mississippi River. * **West Region:** TriWest Healthcare Alliance manages the Western U.S., having taken over from the previous contractor on January 1, 2025. * **Pharmacy:** All pharmacy benefits are managed globally by **Express Scripts**.

## Who this applies to * **Active Duty Service Members (ADSMs):** Required to enroll in TRICARE Prime; 100% of healthcare costs are covered. * **Active Duty Family Members (ADFMs):** Can choose between Prime (no enrollment fees) or Select (no enrollment fees but higher point-of-service costs). * **National Guard & Reserve:** Eligible for TRICARE Reserve Select (TRS) while in a qualified status, which requires monthly premiums ($50+ for individuals in 2026). * **Retirees and Families:** Eligible for Prime or Select until age 65, at which point they typically transition to TRICARE For Life. * **Survivors and Medal of Honor Recipients:** Eligible for continued coverage at specific subsidized rates.

Common scenarios

**1. The Active Duty Spouse (Select Plan)** Sarah is married to an active-duty sailor. She uses TRICARE Select because she prefers a civilian OBGYN who isn't on the local base. In 2026, she pays **$0 in monthly premiums**, but must meet her annual deductible before TRICARE pays its portion of her specialty visits.

**2. The Retired Commander (Prime Plan)** John retired in 2015. He and his wife are enrolled in TRICARE Prime. In 2026, they pay roughly **$760 per year in enrollment fees**. When John sees his PCM for a sinus infection, he pays a flat **$25 copay**.

**3. The Senior Veteran (TFL)** Robert is 70 and has Medicare Parts A and B. He is automatically covered by TRICARE For Life. When he has a $10,000 surgery, Medicare pays first, and TRICARE typically picks up the remaining **"leftover" costs**, often leaving Robert with a **$0 balance**.

## Related terms * **DEERS:** The Defense Enrollment Eligibility Reporting System; the database that proves you are eligible for TRICARE. * **Network Provider:** A doctor or hospital that has a contract with Humana Military or TriWest to provide care at negotiated rates. * **Catastrophic Cap:** The maximum out-of-pocket amount a family will pay for covered services in a single calendar year (e.g., ~$4,000+ for retirees in 2026). * **PCM (Primary Care Manager):** The doctor you see first for regular care and who writes referrals for specialists (required in Prime). * **Qualifying Life Event (QLE):** A change like marriage, birth, or retirement that allows you to change your TRICARE plan outside of Open Season.
