## Quick answer When both spouses are service members, they are considered "Dual Military." You cannot "double up" on TRICARE to get extra benefits; instead, each spouse remains under their own individual coverage as a sponsor, and you must choose which parent will provide TRICARE coverage for your children.

Details

### Active Duty vs. Active Duty If both spouses are on Active Duty, there is no "family plan" that covers both. Each spouse is automatically enrolled in **TRICARE Prime** as an individual sponsor. * **Costs:** There are $0 out-of-pocket costs for Active Duty Service Members (ADSMs). * **Medical Records:** Your medical records remain separate under your own Social Security Number (SSN) or DoD ID.

### Handling Children (The "Sponsor" Choice) If you have children, only one parent can be the "sponsor" for the children's TRICARE coverage. You cannot enroll a child under both parents. * **Strategic Choice:** Most families choose the spouse with the higher rank or longer service history to be the sponsor for the children to ensure continuity if one spouse separates or retires earlier. * **Updating DEERS:** You must visit a RAPIDS office or use ID Card Office Online to designate which parent will be the child's sponsor.

### Active Duty and Reserve/Guard Mix If one spouse is Active Duty and the other is a Drilling Reservist (Selected Reserve): * The Active Duty spouse is covered by TRICARE Prime. * The Reservist spouse is ineligible for TRICARE Reserve Select (TRS) because they are eligible for TRICARE as an Active Duty family member (ADFM). However, they usually remain under their own "Sponsor" status for military duty purposes.

### Retiree Dual Coverage If both spouses are retired from the military: * Each may maintain their own individual coverage. * Alternatively, one can be the sponsor and the other can be the dependent. * **Cost Tip:** Check the **2026 enrollment fees**. For TRICARE Select, paying one "Family" enrollment fee is often cheaper than two "Individual" enrollment fees, depending on your Beneficiary Group (Group A vs. Group B).

### The "No Double Dip" Rule You cannot receive secondary payments from TRICARE. If Spouse A is the sponsor for the children, Spouse B’s TRICARE status cannot be used as "secondary insurance" to cover copays or leftovers from Spouse A’s plan. TRICARE will only pay once per claim.

## Who this affects * **Active Duty Service Members:** Married to another active duty member. * **National Guard & Reserve:** On active duty orders or in a drilling status. * **Retirees:** Both spouses receiving military retired pay. * **Children of Dual-Military Couples:** Requires choosing a single sponsor in DEERS.
