Understanding Medicare Enrollment Periods: AEP, OEP, and Part B Re-Enrollment

Navigating Medicare can feel overwhelming, especially when it comes to knowing when you can make changes or how to get coverage back if you’ve lost it. Below is a clear, easy-to-understand guide to help you stay informed and confident in your decisions.

Annual Enrollment Period (AEP): When You Can Make Changes

The Annual Enrollment Period (AEP) runs every year from October 15 through December 7.

During this time, Medicare beneficiaries can:

  • Change from one Medicare Advantage plan to another
  • Return to Original Medicare
  • Add, drop, or change a Part D prescription drug plan

Any changes made during AEP will take effect on January 1 of the following year.
