Medicare Part D with TRICARE
Answer: Probably not. With TRICARE for Life your prescription coverage is considered creditable which means it is as good as or better than what you could get with a Medicare Part D plan. There is no reason to get other coverage unless you are unhappy with how TRICARE is covering your prescriptions (which I doubt you will be). In that case, you may enroll in a Part D plan without losing your TRICARE. Medicare Part D would pay first, TRICARE would pay second. I assume you are aware you need to enroll in Medicare Part B at or past age 65 once you are no longer active duty.
