To switch from Medicare Advantage to Original Medicare, contact the Medicare Advantage plan provider. Request disenrollment during the Annual Election Period or use the Medicare Advantage Disenrollment Period. Once disenrolled, you can join a stand-alone Prescription Drug Plan and, if needed, purchase a Medigap policy for additional coverage.
