A diagnosis of kidney failure changes life quickly. Regular dialysis becomes part of the weekly routine, and the treatments are expensive — often far beyond what most households could pay on their own. The good news is that Medicare has a special eligibility pathway for people with end-stage renal disease (ESRD), available at any age, not just 65 and older. Here is how eligibility works, when coverage starts, what is covered, and what you can generally expect to pay.
Medicare at Any Age with ESRD
End-stage renal disease means permanent kidney failure that requires a regular course of dialysis or a kidney transplant. ESRD is one of the few conditions that allows people to qualify for Medicare before age 65 — there is no minimum age. To be eligible, you generally must meet both of the following:
- Your kidneys no longer work, and you need regular dialysis or have had a kidney transplant
- You have enough work history under Social Security, the Railroad Retirement Board (RRB), or as a government employee — or you are already getting (or eligible for) Social Security or RRB benefits — or you are the spouse or dependent child of someone who meets one of these requirements
That last point matters for younger patients: even without enough work history of your own, you may qualify through a spouse's or parent's work record.
ESRD is one of two main paths to Medicare before 65 — the other is qualifying for Medicare through a disability. For the standard age-based rules, see our overview of Medicare eligibility requirements.
When Coverage Starts
ESRD Medicare has its own start-date rules, and the timing depends on how you are treated:
- In-center dialysis. Coverage generally begins the fourth month of dialysis — start in May, and ESRD Medicare can generally begin August 1. This waiting period runs from when dialysis starts, not from when you sign up.
- Home dialysis training. Coverage can start as early as the first month of dialysis if you begin a home dialysis training program at a Medicare-certified facility and expect to complete it and self-dialyze.
- Kidney transplant. Coverage can begin the month you are admitted to a Medicare-approved hospital for the transplant or for pre-transplant health services — generally up to two months before the transplant.
Because these rules depend on your treatment plan, confirm your exact start date with Social Security or 1-800-MEDICARE when you apply.
The 30-Month Coordination Period
If you have group health coverage through an employer or union — your own, or a family member's — a special rule applies. For the first 30 months after you become eligible for Medicare because of ESRD, the group health plan pays first and Medicare pays second. This is called the 30-month coordination period, and it generally applies regardless of employer size, and even to COBRA or retiree coverage.
A few important points:
- The 30 months generally start when you first become eligible for ESRD Medicare (usually the fourth month of dialysis), even if you have not enrolled yet
- Many people still enroll in Medicare during the coordination period, because Medicare can pick up costs the group plan does not — such as deductibles, copayments, and coinsurance
- If the group plan already pays most of your dialysis costs, some people delay enrollment until the coordination period ends to avoid paying the Part B premium sooner than needed
- After 30 months, Medicare pays first for Medicare-covered services
One caution for transplant patients: having Part A at the time of a Medicare-covered transplant generally matters for later immunosuppressive drug coverage under Part B, so weigh the enrollment decision carefully. For more on these payer rules, see how Medicare coordinates with employer coverage.
What Medicare Covers for Dialysis and Transplants
ESRD-related care spans both parts of Original Medicare:
- In-center dialysis (Part B). Outpatient dialysis at a Medicare-certified facility, including the doctors' services involved in your care.
- Home dialysis (Part B). Home dialysis equipment and supplies — such as the dialysis machine and water treatment system — plus certain support services, like visits from trained facility staff to monitor your treatments and check your equipment.
- Home dialysis training (Part B). Training for you and your treatment helper, provided by a Medicare-certified training facility.
- Dialysis-related drugs (Part B). Certain medications used in dialysis, including drugs to treat anemia related to ESRD. Related lab tests and diagnostic services are also covered when ordered by your doctor.
- Kidney transplant (Part A and Part B). Part A generally covers the inpatient transplant surgery at a Medicare-approved hospital, plus the kidney donor's donation-related care.
- Immunosuppressive drugs (Part B). After a Medicare-covered transplant, Part B covers anti-rejection drugs — generally as long as you had Part A at the time of the transplant and have Part B when you get the drugs. If ESRD-based Medicare ends 36 months after a transplant and you have no other health coverage, the separate Part B immunosuppressive drug benefit (Part B-ID) can continue covering these drugs — and only these drugs — for a monthly premium.
- Dialysis while traveling. Medicare generally covers dialysis within the United States when you travel — arrange treatment with a Medicare-certified facility at your destination in advance.
Medicare Advantage and ESRD
For many years, people with ESRD generally could not join Medicare Advantage plans. That changed with the 21st Century Cures Act: since January 1, 2021, people with ESRD may enroll in Medicare Advantage plans in their area during regular enrollment periods.
Whether Original Medicare or a Medicare Advantage plan fits better depends on your circumstances. Dialysis patients should check:
- Network access. Medicare Advantage plans use provider networks. Before enrolling, confirm that your dialysis facility, nephrologist, and — if a transplant is planned — your transplant center are in network, and what out-of-network care would cost.
- Out-of-pocket maximums. Medicare Advantage plans include an annual out-of-pocket maximum for covered medical services, while Original Medicare has no such cap on its own. Our guide to Medicare out-of-pocket limits explains this difference.
- Original Medicare flexibility. Original Medicare lets you use any Medicare-certified dialysis facility in the country, which some frequent travelers value.
Neither option is automatically better — compare the plans in your area against your treatment routine and budget.
What Dialysis Costs with Medicare
Under Original Medicare, dialysis is primarily a Part B service with standard cost-sharing:
- You first meet the Part B annual deductible — $283 in 2026
- Medicare then generally pays 80% of the Medicare-approved amount for dialysis services
- You pay the remaining 20% coinsurance
Because dialysis is ongoing, that 20% adds up week after week — and Original Medicare by itself has no annual cap on out-of-pocket costs. Ways people manage this include:
- Medigap (Medicare Supplement) insurance, which can pay some or all of the 20% coinsurance. Federal law only guarantees Medigap access at 65 and older; availability under 65 varies by state.
- Medicaid, which may help with premiums and cost-sharing if your income and resources qualify.
- A Medicare Advantage plan's out-of-pocket maximum, which limits annual spending on covered services.
You also pay a monthly Part B premium, while Part A is premium-free for most people with sufficient work history.
When ESRD-Based Medicare Ends
If ESRD is your only basis for Medicare, coverage generally ends:
- 12 months after the month you stop dialysis, or
- 36 months after the month of a successful kidney transplant
If you later need dialysis or another transplant, coverage generally resumes right away, without a new waiting period. As noted above, the Part B-ID benefit can continue covering immunosuppressive drugs past the 36-month mark for transplant recipients with no other health coverage. If you turn 65 or qualify through disability along the way, your Medicare continues on that basis instead.

- 1-800-MEDICARE (1-800-633-4227) — Medicare's helpline can answer questions about ESRD eligibility, start dates, and coverage. TTY users can call 1-877-486-2048.
- State Health Insurance Assistance Program (SHIP) — SHIP offers free, unbiased counseling on enrollment timing, coverage options, and the 30-month coordination period. Find your local program at shiphelp.org.
- Your dialysis facility's social worker — Most Medicare-certified facilities have social workers who help patients with Medicare enrollment questions every day.
Summary and Next Steps
Medicare's ESRD pathway gives people with permanent kidney failure access to coverage at any age. Key points to remember:
- ESRD qualifies you for Medicare at any age if your kidneys have failed, you need regular dialysis or have had a transplant, and you (or a spouse or parent) meet the work history or benefit requirements
- Coverage generally starts the fourth month of dialysis — or as early as the first month with home dialysis training, or around the time of admission for a kidney transplant
- Employer or union coverage pays first for 30 months; Medicare pays second and can help cover costs your plan leaves behind
- Part B covers in-center and home dialysis, equipment, supplies, training, and post-transplant immunosuppressive drugs; Part A covers the transplant surgery and donor costs
- Since 2021, people with ESRD may join Medicare Advantage plans — check facility and transplant center networks first
- Under Original Medicare, you generally pay the $283 Part B deductible (2026) plus 20% coinsurance with no cap; Medigap (where available), Medicaid, or a Medicare Advantage out-of-pocket maximum may help
- ESRD-based Medicare generally ends 12 months after dialysis stops or 36 months after a successful transplant, though the Part B-ID benefit can continue immunosuppressive drug coverage
If you or a family member has been diagnosed with kidney failure, a good first step is to talk with your dialysis facility's social worker and contact Social Security to confirm your eligibility and start date.
