## Quick answer The Military Health System (MHS) is the massive global network that provides healthcare to nearly 10 million U.S. service members, retirees, and their families. It consists of two main parts: "Direct Care" provided at military hospitals and clinics, and "Purchased Care" provided through the private-sector **TRICARE** insurance program.

In detail

The MHS is managed by the Defense Health Agency (DHA) and the Surgeons General of the Army, Navy, and Air Force. Its mission is two-fold: ensuring the military force is medically ready to deploy and providing a robust health benefit to families and veterans.

### 1. The Direct Care System (MTFs) This includes world-class military treatment facilities (MTFs) like Walter Reed National Military Medical Center. These facilities are staffed by military and civilian personnel. * **Cost:** Generally $0 out-of-pocket for active duty and their families. * **Access:** Active duty service members have first priority; others are seen on a space-available basis.

### 2. The Purchased Care System (TRICARE) When care cannot be provided at an MTF, the MHS uses private-sector providers. This is managed by regional contractors: * **TRICARE East:** Managed by **Humana Military**. * **TRICARE West:** Managed by **TriWest Healthcare Alliance** (as of the T-5 contract transition on Jan 1, 2025). * **Pharmacy:** Managed globally by **Express Scripts**.

### 3. The T-5 Contract and Modernization As of 2026, the MHS has fully stabilized under the **T-5 contract**, which streamlined operations in the West Region under TriWest. The system now focuses heavily on "standardization of care," meaning a beneficiary should experience the same level of service whether they are in San Diego (West) or Norfolk (East).

## Who this applies to * **Active Duty Service Members (ADSMs):** Mandatory enrollment in Prime; 100% coverage at MTFs or authorized civilian clinics. * **Active Duty Family Members (ADFMs):** Can choose Prime (managed care) or Select (PPO-style). * **Retirees and Families:** Must pay annual enrollment fees and cost-shares; eligible for TRICARE For Life if using Medicare. * **National Guard and Reserve:** Eligible for TRICARE Reserve Select (TRS) while in a qualified status.

Common scenarios

**1. The Active Duty Family (Direct Care focus)** Staff Sergeant Miller is stationed at Fort Liberty. His wife and two children are enrolled in **TRICARE Prime**. They receive all primary care at the base clinic. In 2026, their out-of-pocket cost for doctor visits, prescriptions at the base pharmacy, and an emergency appendectomy at the MTF is **$0**.

**2. The Retired Commander (Purchased Care focus)** Commander Higgins (Ret.) lives 40 miles from the nearest base in the West Region. He uses **TRICARE Select**. In 2026, he pays an annual enrollment fee (approx. $540 for an individual). When he sees a specialist in the TriWest network, he pays a negotiated copay (roughly $35–$50 per visit) rather than the full cost of care.

**3. The Pharmacy User** A beneficiary needs a brand-name maintenance medication. By using the **Express Scripts** home delivery service instead of a retail pharmacy, they pay a lower 2026 copay (e.g., $16 for a 90-day supply vs. $48+ at a retail pharmacy).
