This bill aims to enhance TRICARE program access for specific members of the Retired Reserve of the reserve components by amending title 10, United States Code. It adjusts eligibility criteria to ensure that certain individuals under 60 years old, who are qualified for non-regular retirement, can access TRICARE benefits. Specifically, the legislation clarifies that members whose retired pay is offset by disability compensation from the Department of Veterans Affairs (under sections 5304 or 5305 of title 38) are still considered eligible for TRICARE. This change addresses situations where individuals are not actively receiving military retired pay due to the VA offset, preventing their exclusion from TRICARE. The amendments aim to provide fairness and improve healthcare access for these Retired Reserve members , with the provisions taking effect 18 months after the bill's enactment.
