Medicare Basics

Most Americans join Medicare when they turn 65, but it’s also available to younger people with certain disabilities and people with End-Stage Renal Disease (permanent kidney failure that requires dialysis or a transplant).

What is Medicare?

Medicare is a national health insurance program administered by the federal government. It is not part of the Health Insurance Marketplace. Medicare is made up of four parts. Medicare Part A (hospital insurance) and Medicare Part B (medical insurance) are considered Original Medicare. Medicare Part C (Medicare Advantage) and Medicare Part D (prescription drug) are plans offered by insurance companies and private companies that contract with Medicare.
