To enroll in a Medicare prescription drug plan, you must:
- Have Medicare Part A or Medicare Part B (or have both Part A and Part B)
- Live in the prescription drug plan’s service area
- Not be enrolled in another Medicare prescription drug plan at the same time
If you enrolled in a Medicare Advantage Plan, you may only receive your Medicare prescription drug benefits through that plan. Check to see if you already have prescription drug coverage as part of that plan.
