How do you know if you’re eligible for Medicare Part A?
If you are age 65 or above
Entitled to two-year-long Social Security disability
A majority of individuals become eligible for Medicare Part A automatically when they reach the age of 65 if they are already collecting retirement benefits from the Social Security Administration. You may also qualify for Medicare Part A before age 65 if you have a disability, ALS, or an end-stage renal disease. Remember, you must be an American citizen or a legal permanent US citizen for a minimum of 5 consecutive years.
