## Definition A beneficiary is any individual who is eligible to receive health care benefits and services through the TRICARE military health system.

## What it means in practice In the context of TRICARE, being a "beneficiary" means your information is registered in the Defense Enrollment Eligibility Reporting System (DEERS) and you have a verified legal right to military health coverage. Beneficiaries are broadly divided into two groups: **Sponsors** (active duty, retired, or Guard/Reserve members) and **Family Members** (spouses and children). Your specific status as a beneficiary determines your priority for care at military hospitals and your out-of-pocket costs.

For example, in 2026, a "Group A" retiree beneficiary using TRICARE Select might pay an individual deductible of $150 (varies by plan year), while an active duty family member on TRICARE Prime may have $0 out-of-pocket costs for covered services. Your beneficiary category also dictates which regional contractor manages your care: **Humana Military** for the East Region or **TriWest Healthcare Alliance** for the West Region.

It is important to note that "eligibility" does not always mean "enrollment." While all TRICARE beneficiaries are eligible for care, many must actively enroll in a specific plan—like TRICARE Prime or TRICARE Select—to access coverage. If a beneficiary fails to keep their DEERS record updated (such as after a marriage, birth, or divorce), they may lose their "eligible beneficiary" status until the record is corrected.
