Medicare covers dialysis for as long as you need it, with no time limit built into the program itself

If you have Medicare and need dialysis because of kidney failure, Medicare Part B pays for your treatment indefinitely — there is no expiration date or maximum number of sessions. What changes is how much you pay out of pocket, depending on whether you are in your first year of dialysis, whether you have Part D coverage, and which type of dialysis you receive.

The length of your coverage depends on your Medicare status, not on how long you have been dialyzing. As long as you stay enrolled in Medicare Part B, your dialysis sessions are covered. If you drop Part B or lose Medicare may be able to access, your coverage stops.

Key Takeaways

  • Medicare Part B covers dialysis treatment with no time limit — you can receive dialysis for months, years, or the rest of your life and remain covered.
  • Your out-of-pocket costs change after your first year of dialysis; Medicare's payment structure shifts, which may affect your copays and coinsurance.
  • You pay a copay per session for in-center hemodialysis (the amount varies by region and year), plus 20 percent coinsurance on other services like lab work and medications.
  • If you also have Part D, prescription medications for dialysis-related conditions are covered under that plan, not Part B.
  • Staying enrolled in Part B is the only requirement to keep dialysis coverage — missing premium payments or voluntarily dropping the plan ends your coverage.

How Medicare pays for dialysis in your first year

During your first year of dialysis, Medicare covers the treatment under a bundled payment system. This means Medicare pays the dialysis facility a set amount per session, and that payment is meant to cover the dialysis itself, most medications used during treatment, and routine lab work. You pay a copay for each session — the exact amount depends on your region and the year, so ask your dialysis center what your copay will be.

You also pay 20 percent coinsurance on certain services that fall outside the bundle, such as erythropoiesis-stimulating agents (ESAs, which treat anemia), some injectable medications, and certain lab tests. If you have a Medigap or Medicare Advantage plan, that plan may cover some or all of these coinsurance costs.

Medicare Part B also covers the vascular access procedure — the surgery to create a fistula or graft in your arm, or the placement of a catheter — as long as it is medically necessary for dialysis.

What changes after your first year of dialysis

After 12 months of dialysis, your copay structure may change. Medicare adjusts the bundled payment amount, which can affect what you owe per session. The copay itself does not disappear, but the exact dollar amount may shift based on Medicare's annual updates. Your dialysis center can tell you what your new copay will be once you cross the 12-month mark.

The 20 percent coinsurance on services outside the bundle continues throughout your dialysis, regardless of how long you have been receiving treatment. If you develop new conditions or need additional medications, those costs follow the same coinsurance rule.

Peritoneal dialysis and home hemodialysis coverage

If you use peritoneal dialysis (PD) or home hemodialysis instead of in-center treatment, Medicare covers those modalities under the same bundled payment system, but the copay structure differs. For peritoneal dialysis, you typically pay a copay per month rather than per session. For home hemodialysis, the copay is also monthly. Ask your provider what your specific copay will be, since amounts vary.

Medicare also covers the equipment and supplies you need at home — the dialysate, tubing, needles, and the machine itself if you are doing home hemodialysis. These are included in the bundled payment, so you do not pay separately for them beyond your copay.

Training to perform your own dialysis at home is covered by Medicare, including the nurse or technician time needed to teach you the procedure.

Medications and Part D coverage

Medications you take during your dialysis session — such as heparin to prevent clotting — are covered under the Medicare Part B bundle. However, medications you take at home to manage dialysis-related conditions, such as blood pressure medicine, phosphate binders, or iron supplements, are covered under Medicare Part D if you have it enrolled.

If you do not have Part D, you pay the full cost of these home medications out of pocket. Enrolling in Part D during your initial enrollment period or during the annual open enrollment (October 15 to December 7) can reduce what you pay for these drugs. If you miss your initial enrollment window and do not have a may have access to life event, you may face a late enrollment penalty.

What happens if you lose Medicare or stop paying premiums

Your dialysis coverage continues only as long as you remain enrolled in Medicare Part B and pay your premiums on time. If you voluntarily drop Part B, your dialysis coverage ends. If you miss premium payments for three months or more, Medicare may disenroll you, and your coverage stops.

If you lose coverage, you can re-enroll in Part B during the General Enrollment Period (January 1 to March 31 each year), but you may face a permanent late enrollment penalty that increases your premium by 10 percent for each year you were not enrolled. The exception is if you have a may have access to life event — such as losing employer coverage — which may allow you to enroll outside the normal window without penalty.

If you cannot afford your Part B premiums, you may be able to get help through Medicaid or a Medicare Savings Program, depending on your income and state. Contact your state Medicaid office or local Social Security office to learn what programs may be available in your area.

Switching between dialysis types and changing facilities

Medicare covers your dialysis regardless of which type you choose — in-center hemodialysis, peritoneal dialysis, or home hemodialysis — and you can switch between them without losing coverage. If you move to a different dialysis facility, your coverage follows you as long as the new facility is Medicare-certified.

Before you switch facilities, confirm that the new center accepts Medicare and is certified. Most dialysis centers in the United States are Medicare-certified, but it is worth checking. Your current dialysis center or your Medicare plan can help you verify this.

If you are considering a switch, ask the new facility about their copay amount and whether they accept your Medigap or Medicare Advantage plan, if you have one. These details can affect your out-of-pocket costs.

Frequently Asked Questions

Does Medicare stop paying for dialysis after a certain number of years?

No. Medicare covers dialysis indefinitely as long as you remain enrolled in Part B and pay your premiums. There is no maximum number of years or sessions. Your coverage depends on your enrollment status, not on how long you have been dialyzing.

What if I have Medicare Advantage instead of Original Medicare?

Medicare Advantage plans must cover dialysis the same way Original Medicare does, but copays and coinsurance amounts may differ. Contact your plan to learn your specific costs. Some Advantage plans also cover additional services, such as transportation to dialysis or nutritional counseling, that Original Medicare does not.

Do I have to pay for dialysis supplies and equipment?

No. Dialysis supplies and equipment — including the machine, tubing, needles, and dialysate — are covered under the Medicare bundle. You pay only your copay per session or month, depending on your dialysis type. You do not pay separately for supplies.

What if I cannot afford my copays?

If your copays are a financial hardship, talk to your dialysis center's financial counselor. Some facilities have patient information programs or can connect you with nonprofits that help cover dialysis costs. You may also be able to enroll in a Medicare Savings Program if your income is low enough.

Can I keep working while on dialysis and still have Medicare coverage?

Yes. Working does not affect your Medicare coverage or dialysis benefits. However, if you are under 65 and on dialysis, you may have Medicare through the End-Stage Renal Disease (ESRD) program, which covers you regardless of age. If you are over 65, your age-based Medicare coverage continues whether you work or not.
