Tricare for Life is a health care program for military retirees and their eligible family members. It acts as a secondary insurance to Medicare, covering costs that Medicare does not, such as copayments and deductibles. To qualify, beneficiaries must be enrolled in Medicare Part A and Part B. This program is designed to provide comprehensive health coverage for those who have served in the military. It helps ensure that retirees have access to necessary medical services without facing high out-of-pocket expenses, making it an essential benefit for many veterans and their families.
