Many people assume Medicare starts at 65, but that is not the whole picture. If you have a qualifying disability, you may become eligible for Medicare well before then. Understanding how and when can make a real difference in your coverage and costs.
Who Qualifies Under 65
There are three main paths to Medicare before age 65:
- You have received Social Security Disability Insurance (SSDI) for the required period.
- You have ALS (amyotrophic lateral sclerosis, or Lou Gehrig's disease).
- You have end-stage renal disease (ESRD), permanent kidney failure requiring dialysis or a transplant.
Rather than a fixed list of conditions, eligibility through SSDI depends on the Social Security Administration determining that you are disabled and paying you disability benefits.
The 24-Month SSDI Rule
For most people who qualify through disability, Medicare begins after you have received SSDI benefits for 24 months. Coverage generally starts in the 25th month. You do not usually need to apply separately, enrollment is often automatic once you reach that point, and you receive Parts A and B.
Special Rule: ALS
If you are approved for SSDI because of ALS, the 24-month waiting period does not apply. Medicare generally begins the month your disability benefits start, so coverage comes much sooner.
Special Rule: ESRD (Kidney Failure)
People with end-stage renal disease can qualify for Medicare at any age based on kidney failure. The timing depends on your treatment, such as when you start regular dialysis or have a kidney transplant. ESRD has its own enrollment and coverage rules, so it is worth getting guidance specific to your situation. Our guide on chronic kidney disease offers related background.

Check My EligibilityYour Coverage Options
Once you have Medicare, your options are the same as for people 65 and older: stay with Original Medicare, add a Part D drug plan, consider a Medigap policy (availability under 65 varies by state), or choose a Medicare Advantage plan. If you also qualify for Medicaid, a Dual Eligible Special Needs Plan (D-SNP) may offer extra benefits at low or no cost. You may also qualify for help with premiums through Medicare Savings Programs. A licensed advisor can help you sort through which options fit your health and budget.
