Medicare is a federal health insurance program created in 1965 to help pay medical costs incurred by people over the age of 65, people with certain disabilities, and people with end-stage renal disease. Coverage consisted of two parts: Part A (hospital insurance) and Part B (medical insurance).
You'll be automatically enrolled in Medicare when you turn 65 if you're already receiving Social Security benefits, or when you apply for Social Security benefits at age 65.
