Can I Change From Medicare Advantage To Medigap? 
Yes , you can change from Medicare Advantage to Medigap . You must first disenroll from your Medicare Advantage Plan and switch back to original Medicare . If you joined a Medicare Advantage plan when you first signed up for Medicare and are changing to Medigap within 12 months , you can choose from any Medigap policy . If you had a Medigap policy , switched to Medicare Advantage , and decided within 12 months to go back to Medigap , you can get your old policy back if it is still available . However , it will no longer have the prescription drug coverage . You may be able to get that from Medicare Part D.
