Medicare is essentially four main parts, Part A, B, C, and Part D.

What are the 4 Parts of Medicare?


Medicare Part A is one of two parts that make up Original Medicare. Part A helps cover inpatient care in hospitals, care in skilled nursing facilities, hospice care, and some home health care. But remember it doesn’t cover 100%.


Medicare Part B is the second half of Original Medicare. It helps cover certain services from doctors and other health-care providers, outpatient care, home health care, durable medical equipment, and some preventive services. Medicare Part B typically covers only 80% of allowable charges.

It’s important to note that Medicare beneficiaries can have Part A and Part B, or they can have one without the other. Either way, these are often referred to as “Original Medicare.” Some people get both Parts A and B automatically upon turning 65, and others may need to sign up.


Medicare Part C covers all Part A and Part B benefits and services; may offer additional coverage, like vision, hearing, and dental; and may also include Medicare prescription drug coverage (most do). Medicare Advantage plans are offered through Medicare-approved insurance companies. You will find a number of options that may vary based on the county in which you live.


Like Part C, Medicare Part D is run by Medicare-approved, private insurance companies. It helps cover the cost of prescription drugs, and may help lower prescription drug costs and protect against future price increases.
