## Quick answer In the TRICARE system, a **beneficiary** is any individual eligible to receive military health care benefits. This includes active duty service members, retirees, family members, and survivors. TRICARE beneficiaries are divided into two main groups, Group A and Group B, which determines their out-of-pocket costs and enrollment fees.

In detail

TRICARE beneficiaries are managed through the Defense Enrollment Eligibility Reporting System (DEERS). Your status in DEERS dictates which TRICARE plans you can join and how much you pay for care.

### Beneficiary Categories Beneficiaries are generally split into two types: **Sponsors** and **Family Members**.

* **Sponsors:** The person who is or was in the military (Active Duty, National Guard/Reserve, or Retired). * **Family Members:** Spouses and children who are registered in DEERS.

### Group A vs. Group B Cost-sharing depends heavily on when the sponsor joined the military: * **Group A:** Sponsors who enlisted or were appointed before January 1, 2018. * **Group B:** Sponsors who enlisted or were appointed on or after January 1, 2018.

Note: Group B beneficiaries typically have higher enrollment fees but lower catastrophic caps than Group A retirees.

### Plan Eligibility by Beneficiary Type The specific plan a beneficiary can use depends on their location and sponsor status:

| Beneficiary Type | Common Plan Options | Notes | | :--- | :--- | :--- | | **Active Duty (ADSM)** | TRICARE Prime | Must use Prime; $0 out-of-pocket costs. | | **Active Duty Family** | Prime, Select, US Family Health Plan | No enrollment fees for Prime. | | **Retirees & Families** | Prime, Select, TRICARE For Life | Requires annual enrollment fees for most. | | **Guard/Reserve** | TRICARE Reserve Select (TRS) | Requires monthly premiums. | | **Young Adults (21-26)** | TRICARE Young Adult (TYA) | For adult children not otherwise eligible. |

### Enrollment Fees and Costs (2026 Rates) As of 2026, costs vary based on your "Category." For example: * **Active Duty Family Members (Group A):** $0 enrollment fee for TRICARE Select. * **Retirees (Group A):** Annual enrollment fees for TRICARE Select are approximately $189 per individual or $378 per family (2026 rates). * **Catastrophic Cap:** This is the maximum a beneficiary pays out-of-pocket per year. For 2026, the Group A retiree cap is $4,399, while the Group B retiree cap varies—check TRICARE.mil for the most precise current-year adjustments.

## Who this applies to * **Active Duty Service Members (ADSMs):** Includes all branches (Army, Navy, Air Force, Marines, Space Force, Coast Guard) and commissioned corps of the NOAA and USPHS. * **Active Duty Family Members (ADFMs):** Spouses and unmarried children (including stepchildren and adopted children). * **Retirees:** Those who have completed 20+ years of service or received a medical retirement. * **National Guard & Reserve:** Both "drilling" members and those on active duty orders for more than 30 days. * **Survivors:** Spouses and children of deceased service members (eligibility rules change over time). * **Medal of Honor Recipients:** And their eligible family members.

Common scenarios

**Scenario 1: The Active Duty Family (Group A)** Sarah is an Army spouse. Because her husband joined in 2015, they are Group A. She chooses **TRICARE Select**. In 2026, she pays $0 in annual enrollment fees. When she sees a civilian specialist in-network, she pays a small copayment (typically around $27–$30) until she hits her $1,000 deductible.

**Scenario 2: The New Retiree (Group B)** Mark retired in 2026 after joining the Navy in 2019. He is Group B. He chooses **TRICARE Prime**. He must pay a mandatory annual enrollment fee (roughly $400+ for an individual in 2026). However, his primary care visits are $0 as long as he stays within the military hospital system or receives a referral.

**Scenario 3: The College Graduate** Elena is 23, unmarried, and graduated from college. She is no longer eligible for standard TRICARE under her father. She enrolls in **TRICARE Young Adult (TYA) Select**. In 2026, she pays a monthly premium (which can exceed $300+) to maintain coverage until she turns 26.
