When to Enroll in Medicare Part D Plans
When can you enroll in a Medicare Part D plan?
Medicare has specific enrollment periods for Part D enrollment. It is important to understand the various Medicare Part D enrollment periods.
Review them carefully so you don’t miss the enrollment period that applies to you.
Annual Enrollment Period (AEP)
Every year, the AEP begins October 15th and ends December 7th for Medicare-eligible
people to enroll in a plan that works best for them. Coverage begins January 1st
of the following year.
Initial Enrollment Period (IEP)1
Your IEP for enrolling in a Medicare Part D prescription drug plan is a 7-month period that begins 3 months before the month you turn 65, includes the month you turn 65, and ends 3 months after the month you turn 65.
If you’re under 65 you are eligible to enroll in Medicare if you have a qualifying disability and receive a Social Security or Railroad Retirement Board (RRB) disability benefit. You will have a 7-month enrollment window that opens 3 months before your 25th month of receiving Social Security or Railroad Retirement Board benefits and ends 3 months afterwards.
Special Enrollment Period (SEP)
The Special Enrollment Period allows you to join, switch or drop a Medicare prescription drug plan if any of these circumstances apply to you:
- You recently returned to the United States after living permanently outside of the U.S.
- You have both Medicare and Medicaid, or your state helps pay for your Medicare premiums.
- You no longer qualify for Extra Help paying for your Medicare prescription drug coverage.
- You recently involuntarily lost your creditable prescription drug coverage (as good as Medicare’s).
- You get Extra Help paying for Medicare prescription drug coverage.
- In the last 12 months, you left a Medigap policy to join a Medicare Advantage Plan with prescription drug coverage for the first time.
- In the last 12 months, you turned 65 and joined a Medicare Advantage Plan with prescription drug coverage.
- You are leaving/losing/joining an employer or union.
- You belong to a Pharmacy Assistance Program provided by your state.
- You are losing or lost your participation in a Pharmacy Assistance Program provided by your state.
- You recently moved outside the service area for your current plan, or you recently moved and this plan is a new option for you.
- You are disenrolling from a Medicare cost plan that you had prescription drug coverage from.
- You are being disenrolled from a Medicare Special Needs Plan (SNP) because you no longer have special needs status.

- You are disenrolling from your Medicare Advantage Plan between January 1st and February 14th of any year to enroll in original Medicare.
The Special Enrollment Period (SEP) reasons listed above are examples, and they do not include every situation that may
qualify for a SEP enrollment. Your eligibility for a SEP does not convey eligibility to enroll in the plan; in
addition to having a valid enrollment period, an individual must also meet all applicable Part D eligibility criteria.

Medicare Part D plans at any time. This includes joining, changing or dropping a
Medicare prescription drug plan.

birthday, includes your birthday month and ends three months afterward.. There is an exception: if your birthday falls on the first of any month, your 7-month IEP begins and ends one month sooner. For example, if your birthday is July 1, your 7-month IEP is the same as if you were born in June— beginning in March and ending in September. During the 7-month period that starts 3 months before your 25th
month of getting Social Security or RRB disability benefits and ends 3 months after your 25th
month of getting disability benefits. Your coverage will begin the first day of the month after you ask to join a plan. If you join during one of the 3 months before you first get Medicare, your coverage will begin the first day of your 25th
