You may be eligible for Medicare if you have either:

  • Amyotrophic lateral sclerosis (ALS). If you’ve been diagnosed with ALS, also known as Lou Gehrig’s Disease, you become immediately eligible for Medicare upon collecting Social Security disability insurance (SSDI) benefits.
  • End stage renal disease (ESRD). If you have ESRD, also known as end stage kidney disease, and need regular dialysis or a kidney transplant, you’re eligible for Medicare and your coverage can begin shortly after your first dialysis treatment.

  • disabled surviving divorced spouses under age 65
  • disabled children

In most cases, you’ll need to receive care within the U.S.

If you’re imprisoned, generally the correctional facility will provide and pay for your care, not Medicare.
