The Annual Medicare Advantage Open Enrollment period is Jan. 1 through March 31. Consumers who are enrolled in a Medicare Advantage plan on Jan. 1 can switch to another Medicare Advantage plan (with or without drug coverage) or disenroll from their Medicare Advantage plan and return to original Medicare. Anyone wanting to return to original Medicare will be able to join a stand-alone prescription drug plan for Part D coverage. Only one change may be made during this period. Any change made during this period will become effective the first day of the next month. If consumers have specific questions, they can contact their local APPRISE location or call 1-800-783-7067 from 9:00 am to 4:00 pm Monday through Friday.
