The short answer
Many people first qualify at 65. Some qualify earlier through disability benefits, ALS or end-stage renal disease. Eligibility and automatic enrollment are separate questions.
Approaching 65
Confirm eligibility and your application steps with Social Security. Whether you already receive retirement benefits affects whether you need to apply. Working history can affect whether Part A has a premium.
Disability benefits and ALS
Medicare generally begins after 24 months of Social Security disability benefits. People with ALS receive Medicare when disability benefits begin. Review your award notice for your actual coverage dates.
End-stage renal disease (ESRD)
ESRD has separate eligibility and coverage-start rules connected to dialysis or a kidney transplant. Ask Social Security and your care team about your specific situation.
A question worth asking
If I qualify under 65, can I buy any Medigap policy?
Not necessarily. Federal law does not require insurers to sell Medigap to people under 65. Your state may provide additional rights.
