The TRICARE Travel Improvement Act aims to enhance access to specialty medical care for military beneficiaries by reducing the distance required for travel expense reimbursement. Currently, the Secretary of Defense reimburses travel expenses when specialty care is located more than 100 miles from a beneficiary's residence. This bill amends title 10, United States Code, to lower this threshold to 50 miles , making more travel eligible for reimbursement. Furthermore, it explicitly extends this reduced 50-mile requirement to military retirees and their dependents , ensuring they also benefit from the improved travel expense coverage for specialty care.
