When to enroll

Medicare has many enrollment periods and rules around when you can enroll in a Part D plan or make changes to your coverage. Resources on this page can help you select the right enrollment period so you can get affordable and reliable prescription drug coverage when you need it.

Annual enrollment period (AEP)

Sometimes called the annual election period, AEP is when most beneficiaries will make changes to their prescription drug coverage. AEP occurs each year from October 15 through December 7 and you can make changes to your Medicare coverage. Any changes you make will be effective on January 1 of the following year.

Special enrollment period (SEP)

Sometimes called a special election period or open enrollment period, SEPs are available to you when certain events happen in your life. For example, if you move out of a plan’s service area or lose your coverage, you may be entitled to a SEP. This means you would get the opportunity to enroll in a plan or make changes to your coverage outside of the AEP.
