What is one of the main features of TRICARE for Life?

TRICARE for Life is designed to provide comprehensive health care coverage for military retirees and their eligible family members who are also enrolled in Medicare. One of its main features is indeed its structure of eligibility that requires beneficiaries to be eligible for both Medicare and TRICARE. This dual eligibility allows beneficiaries to use Medicare as the primary payer for their health services, with TRICARE acting as a secondary payer that helps cover costs Medicare may not fully cover, such as copayments and deductibles.

This integration ensures that military retirees maintain access to a wide range of medical services while simultaneously benefiting from the protections and coverage provided by both Medicare and TRICARE, thus allowing for a more robust safety net for those who have served in the military. Other options do not accurately reflect the key features of TRICARE for Life, as it is not solely focused on children of military personnel, is applicable to a broader category than just retired military applicants, and does not specifically target low-income veterans only.
