You can join, switch or change plans during specific enrollment periods throughout the year. Here are some details about the most common enrollment periods:
Initial Enrollment Period (IEP)
The IEP is your first chance to sign up for Medicare. Once you become eligible, you have these 7 months to enroll:
- 3 months before the month you turn 65
- The month you turn 65
- 3 months after the month you turn 65

Annual Enrollment Period (also known as “Open Enrollment”)
The Open Enrollment Period runs from Oct. 15 – Dec. 7 each year. You can join, switch or change Medicare health and drug plans. Your coverage will begin on Jan. 1 (as long as the plan gets your request by Dec. 7).
Medicare Advantage Open Enrollment Period (MA OEP)
If you already have a Medicare Advantage plan, the Medicare Advantage Open Enrollment Period is when you can enroll in another Medicare Advantage plan or go back to Original Medicare. Enrollment is from Jan. 1—March 31. However, you can only make 1 change within the period, and other rules apply as well.

Special Enrollment Period (SEP)
If you need to enroll in Medicare Advantage or change your plan outside of the usual Medicare enrollment periods, a Special Election Period (SEP) could be the answer. For information on eligibility, visit our Special Enrollment Period page.
