Who Can Get Medicare Before 65?
Most people get Medicare at 65. You may qualify sooner with disability (SSDI), kidney failure (ESRD), or ALS. Each path has different rules.
The SSDI Route: The 24-Month Rule
If approved for SSDI, you get Medicare after 24 months of benefits. The 24-month period starts from your approval month.
During those 24 months, you may also qualify for Medicaid. Many states cover SSDI recipients with low income. If you have both, you become dual eligible — covered by Medicare and Medicaid at the same time.
At month 24, you're automatically enrolled in Medicare Part A and B. Coverage starts on the first day of the month after your wait ends.
Faster Eligibility: ALS & ESRD
Two conditions let you skip the 24-month wait:
- ALS (amyotrophic lateral sclerosis): No 24-month wait. Medicare starts the same month your SSDI benefits start. (SSI is a different program and does not lead to Medicare on its own.)
- ESRD (End-Stage Renal Disease): You may qualify when you need regular dialysis or a transplant, even without SSDI. Coverage usually starts in your 4th month of dialysis — earlier if you train for home dialysis or have a transplant. Rules differ by treatment, so check with Social Security.
Start Dates by Pathway
When does coverage start for each path:
| Eligibility Pathway | When You Qualify | When Coverage Starts |
|---|---|---|
| SSDI (general disability) | After 24 months of SSDI benefit entitlement | Your 25th month of SSDI benefits |
| ALS (Lou Gehrig's disease) | When SSDI benefits begin — no 24-month wait | Same month your SSDI benefits start |
| ESRD (kidney failure) | Regular dialysis or a kidney transplant | Usually the 4th month of dialysis; earlier for home-dialysis training or a transplant |
What Parts of Medicare Do You Get?
When you become Medicare-eligible through disability, you automatically get:
- Part A (Hospital Insurance): Covers hospital stays, nursing care, hospice, and home health.
- Part B (Medical Insurance): Covers doctor visits, tests, medical equipment, and preventive care.
You can also add:
- Part D (Prescription Drug Coverage): Covers medications. You pay a premium plus copays per prescription. Plans change yearly, so review your options each fall.
- Medicare Advantage (Part C): A private alternative that covers Part A and B services. Usually has lower premiums but may cost more per visit.
- Medigap (Medicare Supplement): Pays costs Original Medicare does not, like copays and deductibles. Availability for people under 65 varies by state.
If You Also Qualify for Medicaid: Dual Eligible Coverage
Many SSDI recipients also qualify for Medicaid. If you have both, you are dual eligible. Medicaid helps pay premiums, copays, and deductibles.
Dual eligible rules vary by state. Your state's Medicaid program decides:
- Whether you qualify based on income and resources.
- What services are covered.
- Whether you can use Medicare Advantage or must use Original Medicare.
- How premiums and cost-sharing work.

Getting Help Paying: Savings Programs & Extra Help
If you have low income, you may qualify for help paying Medicare costs:
- Medicare Savings Programs (MSP): State programs that help pay premiums and copays. Income limits vary by state.
- Extra Help (Low-Income Subsidy): Helps pay for prescription drugs. It's automatic if you have Medicaid, a Medicare Savings Program, or SSI. Otherwise you can apply based on your income and resources — SSDI by itself is not automatic.
- Medicaid: If you also qualify for your state's Medicaid, it can cover costs Medicare does not pay.
What You Need to Do
Contact the Social Security Administration to confirm your Medicare enrollment:
- If you get SSDI, call SSA at 1-800-772-1213 to confirm your benefits received and when month 24 ends.
- With ALS or ESRD, provide documentation to SSA for fast processing.
- Watch your mail for your Medicare card about 3 months before coverage starts.
- If you don't get your card, call 1-800-MEDICARE.
Next Steps
Once Medicare starts, you need to:
- Choose your coverage: Original Medicare or Medicare Advantage, and add Part D if you need it.
- Understand your costs and copays.
- If dual eligible, learn how both programs work.
- If you need financial help, look into assistance programs you may qualify for.
- Review enrollment deadlines and annual changes so you can switch plans if you want to.
