Dialysis can cost $500 or more per treatment without insurance, according to a July 2026 uninsured-dialysis cost review, but there is no single national cash price. For comparison, Medicare’s 2026 base payment for one outpatient ESRD dialysis treatment is $281.71 before patient and facility adjustments, according to the current CMS dialysis payment rule.

Prices outside Medicare can be far higher. A large JAMA Network Open study of employer-sponsored insurance claims found a historical median payment of $1,476 per hemodialysis session from 2012 through 2019. That is not a current uninsured quote, but it shows why the Medicare base rate should never be treated as the retail price of dialysis. The private-payer dialysis study also found substantial geographic variation.

Most people receiving in-center hemodialysis need about three treatments each week. At 156 treatments per year, the unadjusted 2026 Medicare base-rate equivalent is $43,946.76 per year. Actual facility payments and patient bills differ because Medicare adjusts the rate and other coverage may pay part of the patient share.

Article Highlights

• There is no national uninsured dialysis tariff. Self-pay patients should request a written per-treatment cash price from the facility.
• The 2026 Medicare ESRD base payment is $281.71 (at $30 per hour, earning that amount would take about 1.2 full-time workdays, before taxes) per treatment before applicable adjustments.
• Three treatments per week equals about 156 hemodialysis treatments per year.
• The standard 2026 Medicare Part B premium is $202.90 per month and the Part B deductible is $283.
• Under Original Medicare, outpatient dialysis usually leaves the patient paying 20% of the Medicare-approved amount after the Part B deductible.
• ESRD-based Medicare usually begins in the fourth month of dialysis, although qualifying home-dialysis training can make coverage start in the first month.
• If an employer or union group plan applies, it usually pays first during a 30-month ESRD coordination period.

Medicare’s base rate is a bundled facility payment. It covers the dialysis treatment plus many related drugs, laboratory services, supplies, and other renal dialysis services. It is not the same as a provider’s gross charge or a cash price offered to someone without coverage.

What You’re Actually Paying For

Dialysis replaces part of the filtering work that failed kidneys can no longer perform. In-center hemodialysis sends blood through a dialyzer outside the body and is commonly scheduled three times a week for about four hours per treatment.

Home hemodialysis can use more flexible schedules, while peritoneal dialysis uses the lining of the abdomen as the filter and may involve several manual exchanges each day or automated exchanges overnight. The National Institute of Diabetes and Digestive and Kidney Diseases describes standard in-center treatment as three sessions per week and home hemodialysis as three to seven treatments per week depending on the prescription.

Peritoneal dialysis should not be priced as one simple “daily session.” Continuous ambulatory peritoneal dialysis commonly requires at least four exchanges per day, while automated peritoneal dialysis uses a cycler for several exchanges at night. The current NIDDK peritoneal dialysis guide explains those different schedules.

Medicare Changes the Dialysis Bill

Medicare Part B covers outpatient dialysis in a Medicare-certified facility and eligible home dialysis services. After the Part B deductible is met, a person with Original Medicare usually pays 20% of the Medicare-approved amount. Part B also covers eligible home-dialysis training, equipment, supplies, support services, and specified drugs used in outpatient or home dialysis, according to Medicare’s current dialysis coverage rules.

For 2026, the standard Part B premium is $202.90 (about 6.8 hours of work at $30 per hour) per month, the annual Part B deductible is $283, and the Part A inpatient hospital deductible is $1,736 per benefit period. Original Medicare also has no yearly out-of-pocket maximum without supplemental coverage, as shown in Medicare’s 2026 cost schedule.

Original Medicare does not turn a dialysis patient’s total annual healthcare spending into one 20% bill. Hospital services can fall under Part A, the nephrologist can bill professional services separately, and the dialysis facility payment is adjusted for several factors. Medicare Advantage, Medigap, Medicaid, employer coverage, and other insurance can change what the patient eventually owes.

Home Dialysis Does Not Usually Mean Buying the Machine

Home dialysis can move treatment out of the center, but a Medicare-covered patient usually does not need to purchase a dialysis machine outright. The dialysis facility supplies covered home equipment and supplies under Part B when the patient qualifies.

That equipment can include the dialysis machine, water-treatment equipment, basic supplies, and training. The patient may still face costs that Medicare does not cover, including a paid home dialysis aide, lost wages for the patient or helper, or lodging near a treatment location.

Anyone comparing the economics of personal equipment can read our separate guide to the cost of a dialysis machine, but buying one independently is not the standard path for a Medicare-covered home-dialysis program.

Help Paying for Dialysis

More than 90% of Americans with kidney failure have Medicare, according to the National Kidney Foundation’s insurance guidance. Medicaid can also help eligible patients with premiums, deductibles, coinsurance, and services that Medicare does not pay.

The American Kidney Fund operates a Health Insurance Premium Program for financially eligible people receiving dialysis for ESRD in the United States and its territories. The program helped nearly 58,000 patients maintain coverage in 2025, per the current AKF assistance criteria.

Patients should talk with the dialysis facility’s social worker about a large bill. Coverage coordination, Medicaid eligibility, Medicare Savings Programs, premium assistance, provider hardship policies, and state programs can change the amount owed.

Not Starting With the First Treatment

ESRD can make a person eligible for Medicare regardless of age, but coverage is not automatically active for every person with kidney failure. Social Security rules require ESRD plus the applicable insured-status, benefit, spouse, or dependent-child requirements, and the patient must enroll. The Social Security ESRD entitlement rules spell out the additional eligibility requirements.

For someone qualifying for Medicare only because of ESRD, coverage usually starts on the first day of the fourth month of regular dialysis. If dialysis begins July 1, Medicare gives the example of coverage starting October 1. Coverage can begin in the first month when the patient meets the conditions for qualifying home-dialysis training. The current ESRD enrollment guidance also explains that the waiting period can apply even if the person has not enrolled yet.

This creates a real hidden cost. A patient without another payer can face the first three months of treatment before ESRD-based Medicare begins. At a standard three treatments per week, 13 weeks represents about 39 dialysis sessions. The financial exposure depends on the provider’s self-pay rate and whether Medicaid, employer insurance, charity assistance, or another program pays.

The 30-Month Employer Insurance Rule

When a person has qualifying employer or union group health coverage and becomes Medicare-eligible because of ESRD, the group plan usually pays first during the first 30 months after Medicare eligibility begins. Medicare is secondary during that coordination period and becomes primary after it ends.

This rule matters because employer-plan dialysis prices can differ dramatically from Medicare payment rates. It also means someone should not cancel employer coverage solely because ESRD Medicare becomes available. The National Kidney Foundation’s current dialysis insurance guide explains the 30-month coordination period and when Medicare becomes primary.

Three Dialysis Cost Scenarios

Uninsured patient before Medicare starts. A patient begins in-center hemodialysis and has no other coverage. The first three months can contain about 39 treatments before ESRD Medicare normally starts in month four. Because no national self-pay tariff exists, the patient needs the facility’s written cash rate and financial-assistance policy immediately.

Original Medicare without supplemental coverage. Using only the 2026 $281.71 base rate as a constructed model, 156 treatments equal $43,946.76. After a $283 Part B deductible, 20% of the remaining $43,663.76 is $8,732.75. Adding the deductible produces $9,015.75 of illustrative facility cost sharing before other coverage.

Employer-plan patient. A worker with group coverage becomes eligible for ESRD Medicare. The employer plan usually remains primary through the 30-month coordination period, with Medicare potentially paying second. The patient’s bill depends on both plans rather than a universal 20% calculation.

Worked annual Medicare base-rate model

Start with three hemodialysis treatments per week for 52 weeks, or 156 treatments. Multiply by the 2026 ESRD PPS base of $281.71 to get $43,946.76. Subtract the $283 Part B deductible, then take 20% of the remaining amount: $43,663.76 × 20% = $8,732.75. Add the deductible back to get $9,015.75. Add 12 standard Part B premiums at $202.90, or $2,434.80, and the constructed total reaches $11,450.55.

This is not a guaranteed patient bill. The actual Medicare-approved dialysis rate is adjusted, physician care can be billed separately, and supplemental coverage may pay much or all of the coinsurance. The calculation shows why multiplying old annual healthcare-spending figures by 20% produces a misleading answer.

Beyond the Dialysis Chair

Transportation can become a major recurring expense because most in-center patients travel to treatment three times each week. Medicare covers an ambulance to the nearest dialysis facility only in limited cases when another form of transportation could endanger the patient’s health.

Work time is another cost that does not appear on the dialysis claim. NIDDK’s standard in-center schedule is about four hours per treatment, or roughly 624 treatment hours per year at 156 sessions. That equals 78 eight-hour workdays of chair time before travel, check-in, recovery, and medical appointments.

Patients can also face vascular-access surgery, prescriptions outside the dialysis bundle, hospital care, dietary needs, parking, and caregiver expenses. Costs connected with transplantation follow a different payment path, covered in our guide to kidney transplant costs.

Who This Cost Model Makes Sense For

Makes sense if:

• You separate the Medicare facility payment from the provider’s cash price and your own out-of-pocket amount.
• You confirm the exact date ESRD-based Medicare coverage begins instead of assuming the first dialysis treatment is covered.
• You check whether employer insurance or Medicare is primary during the 30-month coordination period.
• You ask the dialysis social worker about Medicaid, Medicare Savings Programs, Medigap, Medicare Advantage, and charitable assistance.

Does not make sense if:

• You multiply the Medicare base rate by 20% and assume it includes every healthcare bill associated with kidney failure.
• You use a historical private-insurance payment as if it were a current self-pay quote.
• You price peritoneal dialysis as one daily “session” without accounting for how the prescribed modality actually works.
• You assume home dialysis requires buying your own machine before checking covered equipment benefits.

What We Verified

• Checked the 2026 CMS ESRD base rate of $281.71 per treatment.
• Confirmed the 2026 standard Part B premium of $202.90, Part B deductible of $283, and Part A deductible of $1,736.
• Cross-referenced the fourth-month ESRD Medicare start rule and first-month home-dialysis-training exception.
• Verified that Original Medicare usually leaves 20% coinsurance for covered outpatient dialysis after the Part B deductible.
• Checked current national kidney-disease data through the 2025 USRDS Annual Data Report program, rather than treating decade-old spending figures as current patient prices.

Answers to Common Questions

How much is one dialysis treatment without insurance?

There is no national cash tariff. A self-pay treatment can cost $500 or more, and some facility prices can be much higher. Ask the dialysis center for its written self-pay rate and financial-assistance policy.

How much does Medicare pay for dialysis in 2026?

The 2026 ESRD PPS base rate is $281.71 per treatment before case, geographic, and other payment adjustments. That is a provider payment benchmark, not necessarily the patient’s bill.

Does Medicare cover 100% of dialysis?

No. Under Original Medicare, outpatient dialysis usually carries 20% coinsurance after the Part B deductible unless another source of coverage pays some or all of that amount.

Does Medicare start on the first day of dialysis?

Usually not when eligibility is based only on ESRD. Coverage normally starts in the fourth month of dialysis, although qualifying home-dialysis training can allow first-month coverage.

Is home dialysis cheaper because I buy my own machine?

No. Medicare Part B can cover eligible home-dialysis equipment and supplies through the dialysis facility. Buying a machine personally is not the normal requirement for covered home treatment.
