## Quick answer Pre-activation care, known formally as Early Eligibility, allows National Guard and Reserve members to access TRICARE benefits up to 180 days before they report for active duty. This benefit ensures service members are medically fit and provides their families with comprehensive health coverage during the transition to full-time service.

## Details When a member of the National Guard or Reserve receives delayed-effective-date active duty orders for more than 30 consecutive days in support of a contingency operation, they and their family members become eligible for TRICARE.

### How it Works Eligibility is triggered when the service member receives their orders. The Defense Enrollment Eligibility Reporting System (DEERS) must be updated to reflect the "early eligibility" status. Coverage begins on the date the orders are issued or 180 days before the reporting date—whichever is later.

### Coverage During Pre-Activation During this period, the benefits match those of active duty members: * **The Service Member:** Effectively becomes "Active Duty" for TRICARE purposes. They are generally enrolled in **TRICARE Prime** (if living in a Prime Service Area) or **TRICARE Prime Remote**. * **Family Members:** Can be covered under **TRICARE Prime** (with no enrollment fees or copays for 2026) or **TRICARE Select**. * **Pharmacy:** Managed by **Express Scripts**, the pre-activation coverage includes full pharmacy benefits at military pharmacies, through home delivery, or at retail network pharmacies.

### Provider Networks and Contractors Coverage administration depends on where the member is located: * **East Region:** Managed by **Humana Military**. * **West Region:** Managed by **TriWest Healthcare Alliance** (as of the T-5 contract transition on Jan 1, 2025). * **Pharmacy:** Managed by **Express Scripts**.

### Transitional Benefits If the member is currently enrolled in **TRICARE Reserve Select (TRS)**, their TRS coverage is suspended automatically once the pre-activation status begins. Because pre-activation coverage is premium-free for the sponsor and family, it represents a significant cost saving compared to paying monthly TRS premiums.

### Important Costs (2026) * **Annual Enrollment Fees:** $0 for Active Duty and their families during pre-activation. * **Network Copays:** $0 for TRICARE Prime users; varies for TRICARE Select users. * **Note:** If a member uses TRICARE Select during this window, they may be subject to the Group A or Group B deductible based on when the sponsor first joined the military.

## Who this affects * **National Guard and Reserve members** called to active duty for more than 30 days in support of a contingency operation. * **Immediate Family Members** (spouses and children) registered in DEERS. * **Service Members in "Early Eligibility" status** Transitioning from civilian employment to federal active duty.
