If you are enrolled in a Medicare Advantage plan and are unhappy with your decision to stay in that plan or you newly enrolled in a MAPD plan for a January 1st 2017 start date and you are having second thoughts about your plan choice, you can leave your plan and switch to Original Medicare. Your Original Medicare coverage will begin the first day of the following month.
If you switch to Original Medicare during this period, you’ll have until February 14 to also join a Medicare Prescription Drug Plan to add drug coverage. Your prescription drug coverage will begin the first day of the month after the plan gets your enrollment form.
NOTE : During this period, you can’t:
Switch from Original Medicare to a Medicare Advantage Plan.
Switch from one Medicare Advantage Plan to another.
Switch from one Medicare Prescription Drug Plan to another.
