Learning about Medicare can be a daunting task. But it doesn’t have to be.

Learn more about what OEP means for Medicare Advantage members

OEP stands for Open Enrollment Period. It’s an enrollment period that allows Medicare members to change their Medicare Advantage plan. OEP begins January 1 and ends March 31. 

During OEP, if you are unhappy with your Medicare Advantage plan, this annual window allows you to make a one-time change to your existing Medicare Advantage coverage.

Perhaps you enrolled in a Medicare Advantage plan without fully understanding its benefits. The Medicare Advantage OEP allows you to switch to another Medicare Advantage plan based on what you like or dislike about your current coverage.

FAQs about OEP

Remember, OEP ends on March 31 and you can only make one change to your existing Medicare Advantage plan during OEP.
