Medicare is health insurance that is funded by the Social Security Administration. This health insurance is available to people who are over the age of 65 or people who are under the age of 65 but qualify for Social Security Disability benefits. The Medicare program consists of four different parts including Medicare Part A, Medicare Part B, Medicare Part C and Medicare Part D.

Original (Traditional) Medicare is administered directly by the federal government. It has two parts:

Part A (Hospital Insurance)

Covers most medically necessary hospital, skilled nursing facility, home health, and hospice care. It is free if you have worked and paid Social Security taxes for at least 40 calendar quarters (10 years); you will pay a monthly premium if you have worked and paid taxes for less time.

Part B (Medical Insurance)

Covers most medically necessary doctors’ services, preventive care, durable medical equipment, hospital outpatient services, laboratory tests, x-rays, mental health care, and some home health and ambulance services. You pay a monthly premium for this coverage.

Medicare Part C (Medicare Advantage Plans)

A type of Medicare health plan offered by a private company that contracts with Medicare to provide you with all your Part A and Part B benefits. Medicare Advantage Plans include Health Maintenance Organizations, Preferred Provider Organizations, Private Fee-for-Service Plans, Special Needs Plans, and Medicare Medical Savings Account Plans. If you’re enrolled in a Medicare Advantage Plan, most Medicare services are covered through the plan and aren’t paid for under Original Medicare. Most Medicare Advantage Plans offer prescription drug coverage.

Medicare Part D (Outpatient Prescription Drug Insurance)

Provides outpatient prescription drug coverage. Part D is provided only through private insurance companies that have contracts with the government—it is never provided directly by the government (like Original Medicare is).

If you want Part D, you must choose Part D coverage that works with your Medicare health benefits. If you have Original Medicare, choose a stand-alone Part D plan (PDP).
