When Is the Open Enrollment period for Medicare? What changes can I make to my Medicare coverage during this time?

The Medicare Open Enrollment period runs from October 15 through December 7 each year. During this period, you can make many changes to your Medicare coverage, depending on the coverage you already have. You can change from traditional Medicare to a Medicare Advantage plan (or vice versa). If you prefer Medicare Advantage, you can choose among the Medicare Advantage plans offered in your area during this period. If you are in traditional Medicare, and want prescription drug coverage, you can choose among Medicare prescription drug plans.
