When Can I Enroll in a 2025 Medicare Advantage (Part C) Plan?

You can only join or switch to a Medicare Advantage (Part C) plan during certain times of the year, called enrollment periods.

By Clover Health

To join a Medicare Advantage (Part C) plan, you must be entitled to Medicare Part A (hospital insurance) and enrolled in Part B (medical insurance).

There are four enrollment periods you need to know about. You can join a Medicare Advantage plan, like Clover Health, during these enrollment periods:

 

  1. Initial Enrollment Period (IEP): This is the seven-month period that begins three months before your 65th birthday, includes your birthday month, and ends three months after your birthday month.
  2. Annual Election Period (AEP): Every year, from October 15 to December 7, you can sign up, change, or drop a Medicare Advantage plan. Your coverage will start on January 1 of the following year. To learn more about AEP, click here 
  3. Open Enrollment Period (OEP): From January 1 to March 31 each year, if you already have a Medicare Advantage plan, you can switch to a different Medicare plan or return to Original Medicare.
  4. Special Enrollment Periods (SEP): You may have a special chance to enroll if certain things happen, such as if you move or lose other insurance coverage. For more information about SEP, click here


We want to help you fully understand Medicare Advantage plans so that you can make confident healthcare decisions. Get helpful insights from the Clover Living blog, or have your questions answered on our Medicare FAQ page. 

 

Don’t wait until the Annual Enrollment Period to start understanding your needs.


Whether you are looking ahead at Medicare for the first time, preparing for the upcoming Annual Enrollment Period, or you have heard about Medicare Advantage Plans and are doing research, there’s no better time to understand your needs than this moment. 

Waiting until December to make a decision could lead you to make the wrong choice. Take the time now to explore the benefits and coverage options of Medicare Advantage plans in your state. Don’t wait until the last minute.
