Original Medicare
Original Medicare includes Part A hospital insurance and Part B medical insurance. It generally lets you use any doctor or hospital that accepts Medicare in the United States. Original Medicare does not include a yearly out-of-pocket maximum for Part A and Part B services.
Medicare Advantage
Medicare Advantage, also called Part C, is another way to receive Medicare-covered services through a private plan approved by Medicare. Most plans include Part D drug coverage. Networks, prior authorization, cost sharing, premiums, and extra benefits vary by plan and location.
Medicare Supplement and Part D
A Medicare Supplement policy, also called Medigap, works with Original Medicare to help pay certain out-of-pocket costs. It is not used with Medicare Advantage. People who keep Original Medicare may consider a standalone Part D plan for prescription drug coverage.
