## Quick answer Under the TRICARE "6" month rule (commonly known as the 60-day or qualifying life event window), beneficiaries generally have 90 days—not 6 months—to make enrollment changes following a life event. However, specific six-month markers apply to retroactive enrollments for newborns and the duration of transitional health benefits (TAMP) for those separating from the military.

## In detail While the number "6" appears in various TRICARE policies, it most frequently relates to timeframes for eligibility, pregnancy, and transitional coverage.

### 1. The 180-Day (6-Month) Transitional Benefit (TAMP) The Transitional Assistance Management Program (TAMP) provides **180 days** of premium-free TRICARE coverage for certain transitioning service members. * **Duration:** Exactly 6 months (180 days) starting the day after separation. * **Eligibility:** Applies to members involuntarily separated under honorable conditions, certain Reserve Component members, and those separating for specific medical reasons. * **Plan Options:** Those in TAMP are eligible for TRICARE Prime or TRICARE Select.

### 2. The 6-Month Pregnancy Window TRICARE policy for pregnancy typically views a "6-month" mark as the transition into the third trimester. * **Prime Referrals:** If you are using TRICARE Prime and move during your third trimester (months 7–9), TRICARE allows for expedited enrollment transfers to ensure continuity of care with an OB/GYN. * **Supplies:** TRICARE covers one manual or electric breast pump per birth event, often requested within the window of 6 months prior to or following delivery.

### 3. Retroactive Enrollment and 6-Month Claims Limits While the standard Enrollment Grace Period for newborns is 90 days (120 days overseas), TRICARE typically allows for the submission of medical claims for up to one year. However, if a beneficiary fails to enroll a newborn within the required window, they may face "Point of Service" charges (50% of the allowed amount) for months 4 through 6 if enrollment is not rectified promptly.

### 4. Regional Contractor Oversight As of May 2026, TRICARE is managed under the T-5 contract by two primary regional contractors: * **East Region:** Humana Military. * **West Region:** TriWest Healthcare Alliance. Both contractors strictly enforce the 90-day Qualifying Life Event (QLE) window for plan changes.

## Who this applies to * **Separating Service Members:** Those eligible for TAMP receive exactly 6 months of coverage. * **New Parents:** Must navigate the 90-day enrollment window to avoid out-of-pocket costs within the first 6 months of the child's life. * **Retirees:** Must choose a plan within 90 days of retirement; if they miss this, they must wait until the next Open Season (usually mid-November to mid-December).

Common scenarios

**The TAMP Transition:** Sgt. Miller separates from the Army via a voluntary separation incentive. His TAMP coverage begins May 13, 2026. He and his family receive 6 months (180 days) of TRICARE Prime benefits at no cost. On November 12, 2026, his TAMP expires, and he must enroll in TRICARE Reserve Select (if eligible) or a civilian plan.

**The Newborn Enrollment:** The Jackson family (TRICARE Select) has a baby on June 1, 2026. They have 90 days to register the child in DEERS and enroll them in a plan. If they wait 6 months to enroll the child, they will likely be responsible for all medical bills incurred between month 3 and month 6, as the "grace period" for automatic coverage has expired.

## Related terms * **TAMP:** Transitional Assistance Management Program; 180 days of premium-free coverage. * **QLE:** Qualifying Life Event; a change like marriage or birth that opens a 90-day enrollment window. * **DEERS:** Defense Enrollment Eligibility Reporting System; the database that tracks military benefits eligibility. * **Open Season:** The annual period (late fall) when beneficiaries can change plans without a QLE. * **T-5 Contract:** The 5th generation of TRICARE contracts, established in 2025, defining East and West regions.
