Jan. 1 to Feb. 14 marks the annual Medicare Advantage disenrollment period. During this time, a Medicare beneficiary enrolled in a Medicare Advantage Plan may leave his or her plan and return to Original Medicare. If you switch to Original Medicare during this period, you will have until Feb. 14 to also join a Medicare Prescription Drug Plan to ensure you will have drug coverage in 2015. Your prescription drug coverage will begin the first day of the month after the drug plan gets your enrollment form.
