What Does Medicare Cover for Home Dialysis?

Does Medicare pay for a home dialysis machine and supplies?

Yes. Medicare.gov's dialysis coverage guidance says Part B covers home dialysis equipment and supplies, including a dialysis machine, a water treatment system, a basic recliner, alcohol, wipes, sterile drapes, rubber gloves, and scissors.

That wording matters because the machine is only one line on the checklist. Home dialysis also depends on the recurring items and treatment setup around it. Medicare's bundled payment approach is designed to keep covered dialysis-related home equipment and supplies from becoming separate bills from multiple suppliers. CMS's 2026 kidney-dialysis booklet says the dialysis facility receives one payment per treatment for these services and items, and beneficiaries cannot be billed separately for items included in that bundled payment.

Here is the practical split: Part A covers dialysis received while you are a hospital inpatient. Part B covers outpatient dialysis and physicians' services at a Medicare-certified dialysis facility or at home. To receive the full ESRD dialysis and transplant benefits through Original Medicare, Medicare.gov says eligible people need both Part A and Part B.

Do not mistake “home” for “everything in the house is covered.” Medicare.gov explicitly excludes paid dialysis aides, lost pay for the patient or helper during training, and a place to stay during treatment. Those are real budget exposures, not footnotes. If treatment affects where and how a household can live, this guide to modifying a home or comparing senior-living options before a health crisis can help frame the housing side of the decision.

What does Medicare Part B cover for home hemodialysis?

Medicare Part B covers outpatient dialysis and physicians' services at a Medicare-certified facility or at home, plus the equipment, supplies, training, and specified clinical support needed for home treatment. The useful way to read this is as a service package, not a shopping list: the facility remains responsible for furnishing medically necessary and reasonable home-dialysis items and services directly or through another provider.

According to Medicare.gov, covered home support can include staff visits to monitor treatment, help in emergencies, and inspect equipment and the water supply. The guidance also includes one in-person visit each month with a physician or certain non-physician providers. That support is not the same as round-the-clock in-home help, and treating it that way is how households get surprised by an uncovered bill.

Water is another place where the details matter. CMS's National Coverage Determination on water purification says a purification system used with a home dialysis unit is covered for either peritoneal dialysis or hemodialysis. Deionization and reverse osmosis meet the stated requirements, but using both in series is medically unnecessary because either can produce sufficiently pure water. Activated-carbon filters can be covered when a physician prescribes them for unsafe chlorine or chloramine concentrations.

There is a narrow exception for water softeners. CMS says they are generally excluded, but coverage can apply when a softener is required to pretreat water entering a reverse-osmosis unit, the water quality falls below the manufacturer's required standard, and the softener is used only for dialysis. Get the dialysis facility's documentation before treating a household plumbing upgrade as a covered expense.

Will Medicare cover training for my caregiver to help with dialysis?

Yes. Medicare Part B covers training for both the patient and the person helping with home dialysis when the training comes from a Medicare-certified home dialysis training facility. This is one of the most valuable coverage rules for a household relying on a spouse, relative, or other helper, because the approved training is part of the covered care pathway rather than an optional extra.

Coverage for training does not turn a caregiver into a paid Medicare home aide. Medicare.gov draws that boundary plainly: paid dialysis aides are not covered, and neither is lost pay for the patient or helper during the training period. Build the household budget around those exclusions before training starts. The clinical training may be covered; time away from work is a separate cost.

CMS's 2026 booklet on kidney dialysis and transplant services gives the clearest Original Medicare cost example. The 2026 Part B annual deductible is $283; after it is met, Medicare pays 80% and the beneficiary pays 20% of covered dialysis-related services and training supervision fees. In CMS's 2026 example, for a $500 physician-supervision fee for home-dialysis training, Medicare pays $400 and the beneficiary pays $100 after the deductible.

Medicare Advantage plans must cover every service Original Medicare covers, CMS states, but networks and out-of-pocket costs vary. A Medigap policy may pay all or part of Original Medicare's 20% coinsurance depending on the policy. The cost-saving move is not guessing from a plan brochure: check the plan's dialysis network, cost-sharing rules, and prior-authorization requirements against the facility providing the training.
