Medicare & Kidney Disease (ESRD): Your 2026 Coverage Guide

Medicare ESRD coverage lets people with permanent kidney failure qualify for Medicare at any age, not just 65. But when that coverage starts depends on how you become eligible and what treatment you're receiving. This guide walks through the timeline, what dialysis and transplant care Medicare pays for, and the rules that catch many families off guard.

What ESRD means and who qualifies

End-Stage Renal Disease (ESRD) is permanent kidney failure that requires either regular dialysis or a kidney transplant to survive. It's one of three paths to Medicare before age 65, alongside long-term disability and amyotrophic lateral sclerosis (ALS), according to the Centers for Medicare and Medicaid Services.1

There's no income test and no age requirement for ESRD-based Medicare, so you can qualify whether you're 35 or 75. There is one other test, though, and it catches people by surprise: you have to be insured under Social Security. That means you (or, if you're claiming as a spouse or dependent child, the person you're claiming through) worked the required amount of time under Social Security, the Railroad Retirement Board, or as a government employee, or already get or are eligible for Social Security or Railroad Retirement benefits.2

When Medicare coverage starts

The start date is where most confusion happens, and getting it wrong can mean unexpected gaps or bills.

If dialysis is your treatment. If ESRD is the only reason you qualify for Medicare, coverage generally cannot start until the fourth month of dialysis. So if you begin dialysis in January, Medicare coverage starts April 1.2

There are two ways out of that wait. The first: if you enroll in a home dialysis training program at a Medicare-certified training facility during those first three months, your doctor expects you to finish the training and do your own dialysis at home, and you keep up a regular course of dialysis through what would have been the waiting period, coverage can begin in the first month of dialysis. This matters because patients who do home hemodialysis or peritoneal dialysis often start that training right away, and catching the earlier start date can save three months of out-of-pocket costs. The second: if a kidney transplant happens during the waiting period, all or part of the three months is waived.2

Know what the wait actually costs, because this is the bill that surprises people. Medicare will not cover surgery or other services you need to prepare for dialysis if they happen before your coverage starts, and Medicare's own example is the surgery to create a blood access, the fistula.2 Inside the three-month wait, that surgery is yours to pay for. Completing home dialysis training changes it, because coverage then starts the month regular dialysis begins and those preparatory services can be covered. It is worth asking your nephrologist about the training program before the fistula is scheduled, not after.

If you're having a kidney transplant. Coverage can start the month you're admitted to a Medicare-certified hospital for the transplant itself, or for pre-transplant evaluation and care, as long as the transplant takes place in that month or within the following two months. You don't have to wait for the surgery date to count. If the transplant ends up delayed more than two months past that admission, coverage instead begins two months before the transplant.2

If you already have Medicare for another reason. If you qualified for Medicare at 65 or through disability before your kidneys failed, ESRD doesn't change when coverage started. You're already enrolled. That also spares you the bill above: someone who already has Medicare is covered for physician-ordered fistula placement and other preparatory services before dialysis begins.2

The 30-month coordination period with employer plans

If ESRD is the only reason you have Medicare and you also have group health plan (GHP) coverage, federal rules set a specific sequence for who pays first.

During the 30-month coordination period, which starts on the date you're first eligible for Medicare because of ESRD, your group health plan pays primary and Medicare pays secondary, regardless of how large the employer is. This applies to GHP coverage on any basis, including retiree coverage, so you don't need to still be working. Once the 30 months are over, Medicare becomes the primary payer as long as you keep ESRD-based Medicare, and a separate 30-month period applies each time you sign up for Medicare because of kidney failure.2

If you already had Medicare through age or disability when you became eligible because of ESRD, the payer order you had just before stays in place. If Medicare was properly paying second under the working-aged or disability rules, it stays secondary for 30 months under the ESRD rules; if Medicare was already paying first, it keeps paying first. In the rare case where ESRD eligibility and age or disability eligibility begin at the same time, the ESRD rules take priority and Medicare pays secondary for the 30 months.2

Why this matters: some people with ESRD assume Medicare takes over immediately, then get caught by claims their group plan handles differently than Medicare would. Knowing the 30-month window in advance lets you plan around it, and it's worth confirming with both your plan and your dialysis center exactly how billing flows during that period.

What Medicare covers for dialysis

Medicare Part B covers outpatient dialysis at 20% coinsurance after the $283 annual Part B deductible, per the CMS 2026 cost announcement. That applies whether you receive dialysis at a center or at home.2,3

Both in-center hemodialysis and home dialysis (including home hemodialysis and peritoneal dialysis) are covered. Medicare also covers home dialysis equipment and supplies, plus home dialysis training from a Medicare-certified training facility.2

Medicare Part A covers dialysis that takes place during an inpatient hospital stay, under the standard inpatient benefit. The Part A inpatient deductible is $1,736 per benefit period in 2026.3

If you also have a Medicare Advantage plan, the plan's cost-sharing rules replace Original Medicare's, so your actual out-of-pocket amounts will depend on the specific plan.

What happens after a kidney transplant

If your transplant is successful and the new kidney continues to function, ESRD-based Medicare coverage ends after 36 months. This is one of the most important and least-discussed rules in ESRD Medicare.2

If you qualified for Medicare only because of ESRD, you'll need to find other coverage after month 36, unless you've also turned 65 or qualify based on disability by then.2

A transplant is not the only thing that ends ESRD-based coverage. If you stop dialysis and haven't had a transplant, coverage ends 12 months after the month dialysis stops, again only if ESRD is your sole basis for Medicare.2

Neither ending is permanent. If dialysis restarts, or another transplant happens, within those windows, coverage resumes, and there is no new three-month waiting period when you come back onto Medicare because of kidney failure.2 So a failed transplant before the 36-month mark puts you back on ESRD-based Medicare without restarting the clock you already served.

One partial protection remains, but you have to sign up for it. Since January 1, 2023, people whose ESRD-based Medicare ends 36 months after a successful transplant can enroll in a separate Part B benefit that covers immunosuppressive (anti-rejection) drugs and nothing else. It is not a substitute for full health coverage, and it isn't automatic: you enroll through Social Security, at any time, and you have to attest that you are not enrolled in and don't expect to enroll in a group health plan, individual insurance, TRICARE for Life, Medicaid or CHIP coverage that includes immunosuppressive drugs, or, if other specific conditions are met, the Department of Veterans Affairs patient enrollment system. If you sign up and later get other health coverage, you must tell Social Security within 60 days of enrolling in it.2

The benefit carries its own costs: a $121.60 monthly premium in 2026 (more at higher incomes), a $283 annual deductible, and 20% coinsurance of the Medicare-approved amount after that.2

Medicare Advantage and ESRD

People with ESRD can enroll in Medicare Advantage plans. Medicare Advantage plans can no longer reject applicants because of an ESRD diagnosis, so you can join any Medicare Advantage plan available in your area.2

For people with ESRD, a Dual Eligible Special Needs Plan (D-SNP) may be worth considering if you also qualify for Medicaid, since these plans are designed to coordinate the two programs, with Medicare paying first and Medicaid able to cover Medicare premiums, cost-sharing, and some care Medicare doesn't cover. See the dual eligibility guide for more detail.4

Costs to plan for

If you're ESRD-eligible and relying on Original Medicare, a few costs tend to catch people off guard.

The standard Part B premium in 2026 is $202.90 a month.3 Since dialysis typically involves three sessions a week, each subject to the 20% coinsurance, that 20% can add up quickly. Some patients qualify for a Medicare Savings Program, which can pay the Part B premium and, for people in the QMB group, Medicare deductibles, coinsurance, and copays as well. These are worth checking if your income is limited.4 See our dual eligibility guide for how these programs work with Medicaid.

Original Medicare has no yearly limit on what you pay out of pocket, unless you have supplemental coverage such as a Medigap policy, Medicaid, or employer, retiree, or union coverage. Medicare Advantage plans can't set an in-network limit above $9,250 for Part A and Part B services in 2026 (plans may set a lower one), and that cap is one protection worth weighing when you compare your options.3

How to Enroll in ESRD Medicare

ESRD Medicare doesn't start on its own: you sign up through the Social Security Administration. For a dialysis patient, coverage generally starts on the first day of the fourth month of dialysis, and that waiting period runs even if you haven't signed up yet. If you don't sign up right away, your coverage can start up to 12 months before the month you apply.2,1 Here is the sequence a newly diagnosed patient follows.
