How To Enroll Your Newborn In TRICARE (2026 Guide)

## Quick answer To enroll your newborn in TRICARE, you must first register them in the **Defense Enrollment Eligibility Reporting System (DEERS)** within 90 days of birth (120 days if overseas). Once registered, the birth is a Qualifying Life Event (QLE) that gives you 90 days to select and enroll the child in a specific plan like TRICARE Prime or Select; otherwise, they may only be covered for a limited time under "automatic" provisions.

In detail

Registering a newborn is a two-step process. You cannot skip step one (DEERS) and go straight to step two (Plan Enrollment).

### Step 1: Register in DEERS You must visit a local RAPIDS ID card office to add your child to DEERS. You do not need the child's Social Security card yet, but you must bring: * The child’s birth certificate or a certificate of live birth from the hospital. * DD Form 1172-2 (Application for Identification Card/Symmetry Enrollment).

**Deadlines for DEERS Registration:** * **Stateside:** 90 days from birth. * **Overseas:** 120 days from birth.

### Step 2: Choose and Enroll in a Plan Once the child shows up in DEERS, they are eligible for coverage. However, they are not permanently enrolled in a specific plan until you take action.

* **TRICARE Prime/Select:** You have **90 days** from the birth (the Qualifying Life Event date) to submit an enrollment application. * **The "Deemed Status":** For the first 90 days, the child is "deemed" to have Prime coverage if the sponsor is Active Duty, but this is temporary. If you miss the 90-day window, you may have to wait until the next Open Season to enroll them, leaving the child with "space-available" care only.

### Regional Contractors (2026) Depending on your location, you will manage enrollment through one of two contractors: * **TRICARE East:** Humana Military. * **TRICARE West:** TriWest Healthcare Alliance.

*Note: Group A includes those whose sponsor entered service before Jan 1, 2018. Group B includes those who entered after that date.*

### Adding a Newborn to the Pharmacy Benefit Newborns are automatically covered by the Express Scripts pharmacy benefit once registered in DEERS. There is no separate enrollment for prescriptions.

## Who this applies to * **Active Duty Service Members:** Coverage is typically automatic for the first 90 days, but active enrollment in Prime or Select is required to maintain civilian provider access. * **Retirees:** Must enroll the child in a plan (Prime or Select) within 90 days and pay any applicable enrollment fee increases. * **TRICARE Reserve Select (TRS) / Retired Reserve (TRRR) Members:** Must add the child to DEERS and then update their policy to a "Member and Family" or "Family" plan via the contractor. 2026 TRS monthly premiums vary; check current rates at TRICARE.mil. * **Overseas Families:** Have 120 days to register in DEERS due to the complexities of international birth certificates and Consular Reports of Birth Abroad.

Common scenarios

### Scenario 1: Active Duty in the West Region Sgt. Miller (Active Duty) welcomes a baby in San Diego on February 1, 2026. He registers the baby in DEERS at the local base on February 10. He then logs into the TriWest portal and enrolls the baby in TRICARE Prime. Because he is Active Duty, he pays **$0** in enrollment fees and **$0** for the birth and follow-up pediatric visits.

### Scenario 2: Retiree in the East Region Major Williams (Retiree, Group A) lives in Florida. His daughter is born on March 15, 2026. He registers her in DEERS but forgets to enroll her in a plan. After 90 days, the "deemed" coverage ends. When he takes her to a civilian pediatrician in July, the claim is denied. He must wait until Open Season or another QLE to enroll her in TRICARE Select, and he may face a "Select Navigator" fee or higher out-of-pocket costs for 2026.
