The main Medicare Open Enrollment Period runs from October 15 through December 7. During this time, those already enrolled in original Medicare or a Medicare Advantage plan can make changes to their coverage. There are two main ways to get your Medicare coverage — original Medicare (Part A and Part B) and Medicare Advantage (Part C). When open enrollment begins, you should shop around for the plan that suits your needs and lifestyle best.
Medicare beneficiaries who already have Part A and Part B can use this election period to enroll in, change, or disenroll from a Part D plan or join a Medicare Advantage plan. Medicare Advantage plan participants can switch Advantage plans or return to original Medicare.
