Medicare and End-Stage Renal Disease (ESRD): Eligibility, Timing, and 2026 Costs

Who qualifies for Medicare because of ESRD

End-stage renal disease (ESRD) is permanent kidney failure that requires either a regular course of dialysis or a kidney transplant to maintain life. When a physician prescribes that treatment, you may become eligible for Medicare based on ESRD at any age — you do not have to be 65 or have a 24-month disability waiting period the way most under-65 enrollees do.

Eligibility based on ESRD is not automatic. In addition to having the diagnosis, you (or a spouse or parent, for a dependent child) generally must have earned enough work credits to qualify for Social Security or Railroad Retirement benefits, or already be receiving those benefits. Children can qualify based on a parent's work record.

• Trigger: a doctor prescribes regular dialysis or a kidney transplant for permanent kidney failure.
• Work history: you, a spouse, or (for a child) a parent meet Social Security/Railroad work-credit requirements.
• Age does not matter — ESRD is a qualifying condition on its own.

When your Medicare coverage actually begins

For most people who start dialysis at a facility, Medicare coverage begins on the first day of the fourth month of dialysis. Practically, that means a roughly three-month waiting period before Medicare starts paying. The clock is tied to the month dialysis begins, not the month you apply.

Two situations move that start date earlier. If you take part in a home-dialysis training program at a Medicare-approved facility — and you begin training before the third month of dialysis and are expected to complete it — coverage can start as early as the first month of dialysis. For a transplant, coverage can begin the month you're admitted to a Medicare-approved hospital for the transplant (or for pre-transplant care), as long as the transplant happens that month or within the following two months.

• Facility dialysis: coverage usually starts the 1st day of the 4th month of dialysis.
• Home-dialysis training (started before month 3): coverage can begin in the 1st month.
• Transplant: coverage can begin the month you're admitted for the transplant or needed pre-transplant care.
• Resuming Medicare after 36 months: if you restart dialysis or get another transplant later, coverage begins immediately with no 3-month wait.

How to sign up

You enroll in Medicare for ESRD through Social Security, not your dialysis clinic. You can apply at a local Social Security office or by calling Social Security at 1-800-772-1213 (TTY 1-800-325-0778). Many people sign up for both Part A (hospital) and Part B (medical), because dialysis, transplant, and most outpatient care fall under Part B.

There's a meaningful grace window: if you're eligible based on ESRD but don't sign up right away, your coverage can be backdated up to 12 months before the month you apply (but no earlier than your eligibility date). So if you became eligible in February and applied in November, coverage could still start in February.

What it costs in 2026

Once your Medicare starts, the standard cost-sharing rules apply. These are verified 2026 figures from CMS and Medicare.gov; your actual amount can be higher with income-related surcharges (IRMAA) or lower with Medicaid or a Medicare Savings Program.

Because dialysis and transplant services are billed heavily under Part B, the Part B deductible and 20% coinsurance matter a great deal for kidney patients — which is why many people pair Original Medicare with a Medigap policy or choose a Medicare Advantage plan to cap or reduce out-of-pocket spending.

• Part B premium: $202.90/month standard (more if IRMAA applies); annual deductible $283.
• Part B coinsurance: you pay 20% of the Medicare-approved amount after the deductible.
• Part A: premium-free with 40+ work quarters; otherwise $311/month (30–39 quarters) or $565/month (under 30 quarters); deductible $1,736 per benefit period.
• Part D drug coverage: out-of-pocket spending is capped at $2,100 for the year; national base premium $38.99/month.
• IRMAA surcharges begin above a modified adjusted gross income of $109,000 (single) or $218,000 (joint), based on 2024 income.

The 30-month coordination period with employer coverage

If you also have a group health plan through your or a family member's job, special coordination-of-benefits rules apply. For 30 months — starting the first month you're eligible for Medicare based on ESRD (usually the fourth month of dialysis), even if you haven't enrolled yet — your group health plan pays first and Medicare pays second. This applies regardless of employer size.

After that 30-month coordination period ends, Medicare becomes the primary payer. Many people still enroll in Medicare during the coordination period anyway, because it can cover costs the group plan leaves behind. If a transplant later fails and you go back on dialysis while you have group coverage, a new 30-month coordination period can begin.

When ESRD-based Medicare ends — and the drug benefit that continues

If Medicare is yours only because of ESRD, coverage isn't necessarily permanent. It ends 12 months after the month you stop dialysis, or 36 months after the month of a successful kidney transplant. (If you also qualify another way — by turning 65 or by disability — that coverage continues.)

There's an important exception for transplant recipients. If your Medicare would otherwise end after a transplant, you can keep a limited Part B benefit that covers only immunosuppressive (anti-rejection) drugs. In 2026 this immunosuppressive drug benefit has a monthly premium of $121.60 (higher with income-related surcharges) and the same $283 annual deductible, after which you pay 20% of the cost. It does not cover any other services.

• Ends 12 months after you stop dialysis.
• Ends 36 months after a successful transplant.
• Transplant recipients can keep a Part B immunosuppressive-drug-only benefit: $121.60/month premium and $283 deductible in 2026.

Original Medicare or Medicare Advantage?

People with ESRD can choose either Original Medicare (Parts A and B, optionally with a stand-alone Part D drug plan and a Medigap policy) or a Medicare Advantage plan. Since 2021, Medicare Advantage plans must accept enrollees with ESRD, so this is a genuine choice rather than a barrier.

Each path trades off differently: Original Medicare lets you use any provider that accepts Medicare and pairs with Medigap to limit out-of-pocket costs, while Medicare Advantage plans bundle benefits and cap annual out-of-pocket spending but use provider networks. Specific benefits, dialysis-center networks, and drug coverage vary by plan and region, so compare the actual plans available where you live before deciding.
