## Quick answer The Defense Health Agency (DHA) is the joint military command that manages the TRICARE health program and oversees the delivery of healthcare to nearly 9.6 million service members, retirees, and their families. Think of them as the "headquarters" that sets the rules and manages the contracts for the East (Humana Military) and West (TriWest) regions to ensure medical readiness across all branches of service.

## In detail The Defense Health Agency was established in 2013 to centralize the management of medical services that were previously handled separately by the Army, Navy, and Air Force. By consolidating these functions, the DHA aims to standardize care, reduce costs, and ensure that a soldier in Florida receives the same quality of care as an airman in California.

### Key Responsibilities of the DHA * **TRICARE Management:** The DHA manages the health plan options (Prime, Select, For Life) and oversees the private-sector contractors who process claims. * **Military Treatment Facilities (MTFs):** The DHA has direct administrative oversight of all military hospitals and clinics worldwide. * **The Quadruple Aim:** The DHA operates under four primary goals: improved readiness, better health, better care, and lower costs. * **Pharmacy Program:** Through Express Scripts, the DHA manages the world’s largest pharmacy benefit program.

### The T-5 Contract and Regional Oversight As of 2026, the DHA oversees the "T-5" (fifth generation) of TRICARE contracts. Under this framework, the DHA holds the contractors accountable for performance metrics:

### Standardization of Benefits Before the DHA’s centralization, military hospitals had varying rules. Under DHA leadership, beneficiaries see standardized processes for: * **Referrals and Authorizations:** Standardized through the Defense Health Agency’s "Right and Ready" clinical guidelines. * **Patient Portals:** The rollout of MHS GENESIS, a single electronic health record system managed by the DHA, allows your records to follow you from a combat zone to a stateside MTF.

## Who this applies to * **Active Duty Service Members (ADSMs):** The DHA ensures they are medically ready for deployment and manages their care exclusively through TRICARE Prime. * **Active Duty Family Members (ADFMs):** The DHA dictates their enrollment windows and the 2026 out-of-pocket maximum (Catastrophic Cap) of $1,000 for Group A. * **Retirees and Families:** The DHA manages the transition to TRICARE Select or Prime and sets the 2026 enrollment fees. * **National Guard and Reserve:** The DHA oversees the TRICARE Reserve Select (TRS) and TRICARE Retired Reserve (TRR) programs.

Common scenarios

**Scenario 1: Navigating a Specialist Referral** Sergeant Miller (Active Duty) is stationed at Fort Cavazos. The DHA-managed hospital determines he needs a cardiologist. Because the DHA has standardized the referral process, his referral is automatically sent to TriWest (the West Region contractor). Under DHA rules, if the MTF cannot see him within 28 days, TriWest must authorize him to see a civilian provider at $0 out-of-pocket for Miller.

**Scenario 2: The Retiree Enrollment Fee** Major (Ret.) Jones is in TRICARE Select (Group A). For the 2026 plan year, per DHA regulations, he pays an annual enrollment fee (roughly $380 for an individual or $760 for a family — *check TRICARE.mil for final 2026 index adjustments*). The DHA ensures these funds are collected to offset the cost of the private-sector care network.

**Scenario 3: Pharmacy Costs at Retail** A Navy spouse fills a brand-name maintenance medication at a CVS. Because the DHA manages the pharmacy contract through Express Scripts, the spouse pays a standard 2026 co-pay (typically $43 for a 30-day supply of a brand-name formulary drug) or can choose to use a military pharmacy for $0, a policy set by the DHA.

## Related terms * **MHS (Military Health System):** The umbrella term for all military medical entities, including the DHA and the service medical departments. * **T-5 Contract:** The current multi-billion dollar agreement between the DHA and regional contractors (Humana/TriWest). * **MHS GENESIS:** The DHA’s unified electronic health record system. * **DEERS:** The database used by the DHA to verify that you are eligible for TRICARE benefits. * **Defense Health Board:** A federal advisory committee that provides independent advice to the DHA leadership.
