Special circumstances (Special Enrollment Periods)


You can make changes to your Medicare Advantage and Medicare prescription drug coverage when certain events happen in your life, like if you move or you lose other insurance coverage. These chances to make changes are called Special Enrollment Periods (SEPs). Rules about when you can make enrollment changes and the type of Medicare plan changes you can make are different for each SEP.

Note
If you believe you made the wrong plan choice because of inaccurate or misleading information, including using Plan Finder, call 1-800-MEDICARE and explain your situation. Call center representatives can help you throughout the year with options for making changes.
What can I do?
