There are two main parts of Medicare, each with their own eligibility requirements. Medicare Part A is available for anyone who is over age 65 or who is permanently disabled and who is eligible for Social Security.
You are eligible for Medicare Part A if you:
- are a United States resident who has reached age 65 and are either a U.S. citizen or a legally admitted alien who has resided in the U.S. continuously for at least five years;
- are a disabled person of any age who has been entitled to Social Security, widows, or Railroad Retirement disability benefits for 25 months; or
- have end-stage renal disease that requires dialysis treatment or a kidney transplant.
Medicare Part B is available for anyone over age 65 regardless of Social Security eligibility.
