Medicare-eligible beneficiaries are able to use the TRICARE Pharmacy Program
benefits. However, TRICARE beneficiaries who turned 65 on or after April 1, 2001, are required to be enrolled in Medicare Part B. If you choose not to enroll, your pharmacy benefit is limited to the medications available at military treatment facility (MTF) pharmacies.
Medicare-eligible beneficiaries are also eligible for Medicare Part D prescription drug plans. However, you do not need to enroll in a Medicare Part D prescription drug plan to keep your TRICARE benefit.
For the most current information about Medicare Part D, call Medicare at 1-800-MEDICARE (1-800-633-4227) or visit the Medicare Web site at www.medicare.gov
