Part A covers inpatient hospital stays, care in a skilled nursing facility, hospice care, and some home health care.
Most of the time Part A does not cost a dime.
Medicare Part B is outpatient medical coverage. Part B helps pay for medically necessary services performed on an outpatient basis that are needed to diagnose and treat a medical condition.
Surgeries, lab work, and preventative services are all covered under Part B.
Medicare Part C is also called Medicare Advantage (MA). It’s an alternative benefit form to Original Medicare. Medicare Advantage may include prescription drug coverage, along with other extra benefits. It is offered through private insurance companies, so you don’t enroll in it at the Social Security office or website.
Medicare Supplement plans, also called Medigap, are designed to work with Original Medicare Parts A and B. Medigap policies help pay for some health care costs not covered by Original Medicare, such as deductibles, coinsurance and foreign travel emergency.
