If you are looking for a Medicare plan to better fit your lifestyle, or if you are looking to lower your costs, you can switch to another Medicare plan. This is typically done during the Annual Enrollment Period (AEP) of October 15 - December 7 each year. If you enroll by December 7, your plan coverage goes into effect on January 1.

Frequently Asked Questions
You’re eligible to change plans during a specific time of the year, called the Annual Enrollment Period (AEP). AEP runs from Oct 15 to December 7. During this period you can enroll in Medicare Advantage, switch plans, or leave your plan. You’re also eligible to switch your plan during the Open Enrollment Period (OEP), which runs from January 1 to March 31.
Some people may also qualify for coverage outside of standard enrollment periods, during the Special Enrollment Period (SEP). SEP takes place when certain qualifying events happen, including losing your employer coverage, moving, or retiring.
