The A-B-C-D’s of Medicare


Part A: Hospital/Inpatient Insurance

Part A helps pay for your care while you are in the hospital. It also pays some of the costs if you stay in a skilled nursing facility after a hospitalization and if you have a medical need for limited, skilled health care at home. You can’t be turned down because of your medical history or pre-existing illness.


Part B: Outpatient Health Insurance

Part B helps pay for doctors’ services, outpatient hospital care, and home health care that Part A does not pay for. It also provides coverage for laboratory tests, ambulance services, and many screenings and preventive services that can help you to stay healthy, including a Welcome to Medicare Exam and Annual Wellness Visits. A monthly premium is charged for Part B services.


Part C: Medicare Advantage (MA)

Medicare Advantage plans (sometimes called Part C) are private insurance plans that deliver Medicare Part A and Part B coverage. Some of these plans also provide Medicare drug coverage. Medicare Advantage plans also may cover additional services that Original Medicare does not pay for—for example, coverage for vision and hearing care. Most Medicare Advantage plans have a network of doctors and hospitals.


Part D: Prescription Drug Coverage

Medicare Part D helps you pay for your prescription drugs. If you have or are eligible for Medicare Part A or Part B or have both, you are eligible to join a Part D plan. You must join a private insurance plan to get Medicare’s drug coverage. There is no screening for pre-existing conditions. Plans must accept everyone who is eligible and enrolls, but you can only join at certain times of the year. Most people can join or change Part D plans during the Annual Election Period from October 15th through December 7th, with coverage starting on January 1, 2022.
