What causes TRICARE Reserve Select and TRICARE Retired Reserve members to lose eligibility?

Becoming eligible for the Federal Employees Health Benefits (FEHB) program is indeed a valid reason for TRICARE Reserve Select and TRICARE Retired Reserve members to lose eligibility. When an individual qualifies for FEHB, they can access a different set of health benefits specifically designed for federal employees, which supersedes their eligibility for TRICARE options. This eligibility transition signifies a shift in the individual's healthcare coverage pathway, which is integral in maintaining an organized healthcare system for service members and federal employees alike.

On the other hand, factors such as transitioning to civilian employment, loss of military status, or reaching retirement age do not directly trigger the loss of eligibility for TRICARE Reserve Select or TRICARE Retired Reserve. Each of these circumstances may impact military benefits overall, but eligibility for TRICARE remains intact until a member meets specific criteria like qualifying for FEHB. Thus, understanding the specifics of eligibility helps in navigating these transitions effectively.
