## Quick answer TRICARE eligibility is primarily determined by your status in the Defense Enrollment Eligibility Reporting System (DEERS). Generally, active duty service members, military retirees, their families, and certain survivors or former spouses are eligible for coverage.
Details
Eligibility for TRICARE is not a "one-size-fits-all" status. It depends on who you are (sponsor or family member) and your current military status (active, retired, or reserve). Enrollment in a specific plan—like TRICARE Prime or TRICARE Select—often depends on your geographic location.
### Primary Eligibility Categories * **Active Duty Service Members (ADSMs):** Automatically eligible and required to enroll in TRICARE Prime. There are $0 out-of-pocket costs for 2026 for all covered medical care. * **Active Duty Family Members (ADFMs):** Eligible for TRICARE Prime (no enrollment fees) or TRICARE Select. For 2026, those in Group A (sponsor entered service before Jan 1, 2018) generally have lower catastrophic caps than Group B. * **Retirees and Family Members:** Eligible for TRICARE Prime (in Prime Service Areas) or TRICARE Select. Retirees must pay annual enrollment fees. For 2026, these rates vary based on whether you are in Group A or Group B—check the official TRICARE portal for the exact inflation-adjusted figures for the current plan year. * **National Guard and Reserve:** * On active duty for more than 30 days: Same benefits as ADSMs. * Qualified non-active status: May purchase **TRICARE Reserve Select (TRS)**. * Retired Reserve (under age 60): May purchase **TRICARE Retired Reserve (TRR)**.
### Special Eligibility Cases * **Survivors:** Spouses and children of deceased service members remain eligible, though status (active duty vs. retiree rate) may change over time. * **Former Spouses:** You may be eligible if you were married to the sponsor for at least 20 years, the sponsor served for at least 20 years, and the marriage/service overlapped by at least 20 years (the 20/20/20 rule). * **Medal of Honor Recipients:** Recipients and their families are eligible for TRICARE regardless of their initial service duration.
### DEERS: The Gatekeeper The most important factor in eligibility is the **Defense Enrollment Eligibility Reporting System (DEERS)**. If your information is not updated in DEERS by your sponsor (e.g., following a marriage, birth, or divorce), TRICARE will deny claims. Eligibility cannot be granted by the regional contractors (Humana Military or TriWest); it must be reflected in DEERS first.
## Who this affects * **Active Duty:** Army, Navy, Air Force, Marine Corps, Space Force, and Coast Guard. * **National Guard/Reserve:** Selected Reserve and Individual Ready Reserve. * **Retirees:** Both "regular" retirees and "gray area" retirees (Guard/Reserve under age 60). * **Family Members:** Spouses and unmarried children (up to age 21, or 23 if a full-time student). * **Young Adults:** Children age 21–26 may qualify for TRICARE Young Adult (TYA) if not otherwise eligible.
