What is the Medicare Annual Enrollment Period?

Published by Medicare Made Clear®


Medicare Annual Enrollment Period explained

The Medicare Annual Enrollment Period – AEP for short – is a set time each year for changing your Medicare coverage choices if you choose to. AEP runs from October 15 to December 7. New coverage choices go into effect on January 1.

What changes can I make during the Medicare Annual Enrollment Period?

The specific actions you can take during AEP depend on your current coverage. Check your situation below for a run-down on what you can do.

I currently have just Original Medicare (Parts A & B).

  • Join a Medicare Advantage plan (Part C) with or without built-in drug coverage. Note that you may be charged a penalty if you do not currently have other creditable drug coverage.
  • Join a stand-alone Medicare prescription drug plan (Part D). A penalty may apply here as well if you do not currently have other creditable drug coverage.
  • Make no changes and your current coverage will renew as is.

  • Switch from your current Medicare prescription drug plan to another Medicare prescription drug plan.
  • Drop Medicare prescription drug coverage completely. Note that you may be charged a penalty if you decide you want drug coverage again later.
