Medicare is a government program administered by the Federal Centers for Medicare and Medicaid Services. It offers health insurance if you're 65 or older and receive Social Security or Railroad Retirement Board (RRB) benefits. If you're younger than 65, you may be able to get Medicare if you have kidney failure, Amyotrophic Lateral Sclerosis (ALS) or are disabled.
Traditional Medicare includes Parts A and B. Most people get Part A for free, but if you do not qualify for Social Security or RRB benefits, you may have to pay for Part A. Everyone has to pay each month for Part B.
