Medicare Advantage Open Enrollment Period (MA OEP)

The Medicare Advantage Open Enrollment Period (MA OEP) is an annual period during which Medicare Advantage enrollees have the opportunity to make changes to their Medicare Advantage plans. This period typically occurs from January 1st through March 31st each year. During the MA OEP, beneficiaries can switch Medicare Advantage plans, return to Original Medicare, or enroll in a Medicare Part D prescription drug plan, if eligible. Changes made during the MA OEP generally take effect on the first day of the month following the month in which the change is made. It’s important for beneficiaries to review their plan options carefully during this period to ensure they have coverage that meets their healthcare needs.
