Medicare Advantage Open Enrollment Period
(For Individuals Currently Enrolled in a Medicare Advantage Plan)

The Medicare Advantage Open Enrollment Period (OEP) gives you the opportunity to enroll in another Medicare Advantage (Medicare Part C) plan or go back to Original Medicare (Medicare Part A and Medicare Part B). Normally, you can only make a change one time during OEP.
Medicare OEP is different from the enrollment period in the fall. Anyone that is Medicare eligible may make changes during the Annual Enrollment Period (AEP).
