Medicare 101

A brief overview of Medicare Coverage


What's Medicare?

Medicare is the federal health insurance program for people who are 65 or older, certain younger people with disabilities, and people with End-Stage Renal Disease (permanent kidney failure requiring dialysis or a transplant, sometimes called ESRD). The different parts of Medicare help cover specific services:

Medicare Part A - Hospital Insurance

Part A covers inpatient hospital stays, care in a skilled nursing facility, hospice care, and some home health care.

Medicare Part B - Medical Insurance

Part B covers certain doctors' services, outpatient care, medical supplies, and preventive services.

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 - Prescription Drug Coverage

Part D adds prescription drug coverage to Original Medicare, some Medicare Cost Plans, some Medicare Private-Fee-for-Service Plans, and Medicare Medical Savings Account Plans. These plans are offered by insurance companies and other private companies approved by Medicare. Medicare Advantage Plans may also offer prescription drug coverage that follows the same rules as Medicare Prescription Drug Plans.

Medigap Policy

A Medigap policy is health insurance sold by private insurance companies to fill gaps in Original Medicare coverage. Medigap policies can help pay your share (like coinsurance, copayments, or deductibles) of the costs of Medicare covered services.
