Medicare Eligibility Under 65: How to Qualify Before Age 65
Medicare isn’t only for people 65 and older. Understanding Medicare eligibility under 65 can help you or a loved one know exactly when coverage begins and what to expect from the enrollment process.
Who Qualifies for Medicare Under 65?
When you’re under 65, you become eligible for Medicare if:
- You have received Social Security Disability Insurance (SSDI) checks for at least 24 months, or
- You have been diagnosed with End-Stage Renal Disease (ESRD)
Medicare Disability Eligibility: Qualifying Through SSDI
You may qualify for Medicare eligibility under 65 due to disability if you’ve been receiving SSDI checks for more than 24 months — commonly known as the two-year waiting period.
How the waiting period works:
- The two-year waiting period begins the first month you receive an SSDI check
- You’ll be automatically enrolled in Medicare at the start of the 25th month you receive an SSDI check
Is There an Exception for ALS?
Yes. If you receive SSDI because you have Amyotrophic Lateral Sclerosis (ALS), Medicare begins automatically the first month your SSDI benefits start — there is no two-year waiting period.
Important to know: Social Security — not Medicare — determines whether you qualify for SSDI checks and administers the program. For questions about SSDI, contact your local Social Security Administration (SSA) office.
Note: Railroad workers should contact the Railroad Retirement Board for information about disability annuities and Medicare eligibility.
Medicare Eligibility for ESRD
You may qualify for Medicare under 65 due to ESRD if you’ve been diagnosed with kidney failure and:
- You’re getting dialysis treatments or have had a kidney transplant, and
- One of the following applies:
- You’re eligible to receive SSDI
- You’re eligible to receive Railroad Retirement benefits
- You, a spouse, or a parent have paid Medicare taxes for a sufficient amount of time, as specified by the Social Security Administration
When Does ESRD Medicare Coverage Begin?
If you’re under 65 with ESRD, when your Medicare benefits begin depends on your specific circumstances, including:
- When you apply for Medicare
- Whether you receive dialysis at home or at a facility
- Whether you receive a kidney transplant
If you’re eligible for ESRD Medicare, you can enroll in Parts A and B together at any time. Part A coverage can be retroactive up to 12 months — but it cannot start earlier than the first month you were eligible for ESRD Medicare.
Note: Railroad workers with ESRD must contact Social Security — not the Railroad Retirement Board — to determine Medicare eligibility.
