How much does dialysis cost?
$250 – $500 per session
$37,000 – $90,000 per year
$3,100 – $3,400 per month (Medicare)
Average dialysis cost
Dialysis costs in the United States average $37,000 to $90,000 per year depending on the type of treatment, the facility, and the patient's insurance coverage. A single hemodialysis session typically costs $250 to $500, and most patients require three sessions per week, totaling roughly 156 treatments annually. These costs include the facility fee, physician supervision, medications administered during treatment, and supplies.
| Cost metric | Estimated cost |
|---|---|
| Single hemodialysis session | $250 – $500 |
| Annual hemodialysis cost (156 sessions) | $37,000 – $78,000 |
| Monthly outpatient dialysis (Medicare) | $3,100 – $3,400 |
| Monthly outpatient dialysis (individual market) | $10,000 – $10,200 |
| Average total monthly spending (all services, ESKD patient) | $14,399 |
More than 750,000 people in the United States live with end-stage kidney disease (ESKD), and over 70% of them receive regular dialysis treatments. Because dialysis is a life-sustaining therapy, understanding how much it costs, who pays, and what financial resources are available is critical for patients and their families.
Dialysis cost by type
The two primary types of dialysis, hemodialysis and peritoneal dialysis, differ significantly in cost, setting, and logistics. Hemodialysis performed in a clinical facility is generally more expensive than peritoneal dialysis done at home, though home hemodialysis offers a middle-ground option for some patients.
| Dialysis type | Setting | Estimated annual cost |
|---|---|---|
| In-center hemodialysis | Dialysis clinic or hospital | $50,000 – $90,000 |
| Home hemodialysis | Patient's home | $40,000 – $70,000 |
| Peritoneal dialysis (CAPD/APD) | Patient's home | $37,000 – $55,000 |
In-center hemodialysis
In-center hemodialysis is the most common form of dialysis in the U.S. Patients visit a dialysis facility three times per week for sessions lasting approximately four hours each. The higher cost reflects staffing, equipment, and facility overhead. Under Medicare's Prospective Payment System, the base facility fee is approximately $239 per session, plus a physician supervision fee of about $240 per month.
Home hemodialysis
Home hemodialysis allows patients to perform treatments at home with proper training and equipment. While it reduces facility and transportation costs, patients must invest in home dialysis equipment, water treatment systems, and ongoing supplies. Medicare Part B covers home dialysis training, equipment, and supplies, making it a viable option for many patients seeking greater flexibility.
Peritoneal dialysis
Peritoneal dialysis uses the lining of the abdomen to filter blood and can be performed daily by the patient. It tends to be the least expensive option because it avoids frequent clinic visits, uses less complex equipment, and requires fewer healthcare workers. There are two main forms: continuous ambulatory peritoneal dialysis (CAPD) and automated peritoneal dialysis (APD).
How insurance covers dialysis
Most dialysis patients in the United States have their treatment covered, at least in part, by health insurance. Approximately 85% to 90% of patients receiving dialysis are insured by Medicare. However, patients may still face out-of-pocket costs including premiums, deductibles, co-insurance, and copayments depending on their plan.
| Insurance type | Coverage details | Patient responsibility |
|---|---|---|
| Medicare Part B | Covers 80% of outpatient dialysis | 20% co-insurance |
| Medicare + Medigap | Covers up to 100% of dialysis costs | Monthly Medigap premium |
| Private insurance (employer) | Varies by plan | Copays, deductibles, co-insurance |
| Medicaid | Covers most or all costs for eligible patients | Little to no out-of-pocket cost |
| ACA individual market | Covers dialysis at negotiated rates | Copays, deductibles, co-insurance |
The three most common types of health insurance for dialysis patients are Medicare, private health insurance (through an employer or the ACA marketplace), and Medicaid for people with low income or disabilities.
Medicare coverage for dialysis
Medicare is the dominant payer for dialysis in the United States. People with kidney failure, also called ESKD, qualify for Medicare regardless of age, making it a unique benefit within the Medicare system. To qualify, you must be a U.S. citizen or legal resident and have worked (or be the spouse or dependent of someone who has worked) at least 40 quarters (10 years) while paying Social Security and Medicare taxes.
| Medicare part | What it covers for dialysis | Costs to patient |
|---|---|---|
| Part A (hospital insurance) | Inpatient dialysis, hospital stays | Premium-free if work requirements met; deductible and co-insurance apply |
| Part B (medical insurance) | Outpatient dialysis, home dialysis training and equipment, medications during treatment | Monthly premium; 20% co-insurance after deductible |
| Part D (prescription drugs) | Prescription medications related to kidney disease | Monthly premium, deductible, copays |
Medicare waiting period
Most people starting dialysis can get Medicare, but there is typically a waiting period of three months before coverage begins. During this waiting period, patients may rely on private insurance, Medicaid, or other assistance programs. Some patients who already have employer-based insurance may use that as primary coverage, with Medicare serving as secondary coverage during the first 30 months.
Medigap supplemental plans
Medicare Part B covers 80% of dialysis costs, leaving the patient responsible for the remaining 20%. A Medigap (Medicare Supplement) plan can help cover that 20% co-insurance, along with deductibles and other out-of-pocket expenses. For a patient spending $50,000 per year on dialysis through Medicare, the 20% co-insurance would be $10,000 out of pocket without supplemental coverage.
You do not need to be 65 or older to qualify for Medicare if you have been diagnosed with end-stage kidney disease. ESKD is one of the few conditions that grants Medicare eligibility to patients of any age, as long as they meet the work history requirements.
Dialysis cost without insurance
Without insurance, dialysis costs can be devastating. A single hemodialysis session billed to an uninsured patient may cost $500 to $1,000 or more, depending on the facility and location. Over a full year of treatment (156 sessions), uninsured patients could face bills of $78,000 to $156,000 or higher.
| Scenario | Estimated annual cost |
|---|---|
| Uninsured (in-center hemodialysis) | $78,000 – $156,000+ |
| Uninsured (peritoneal dialysis) | $55,000 – $80,000+ |
Because of these extreme costs, very few patients remain uninsured for long. Dialysis clinic social workers can help patients apply for Medicare, Medicaid, or other financial assistance programs. If you do not have insurance and need dialysis, speaking with the social worker at your clinic should be an immediate priority. You can also explore the cheapest ways to see a doctor without insurance for related medical needs.
Private insurance vs. Medicare spending
Private insurance plans pay significantly more for dialysis than Medicare does. Research published in JAMA Internal Medicine found that individual market plans spent approximately $10,149 per month on outpatient dialysis, over 300% of what Medicare pays for the same services. This massive pay differential has raised concerns among policymakers about cost inflation and patient steering.
| Payer type | Monthly outpatient dialysis spending | Comparison |
|---|---|---|
| Medicare | ~$3,100 – $3,400 | Baseline |
| Individual market (ACA) | ~$10,149 | ~3x Medicare rate |
| Employer-sponsored private | $5,000 – $8,000 | ~1.5x – 2.5x Medicare rate |
Concerns about patient steering
Some policymakers have raised concerns that dialysis facilities may be encouraging patients to enroll in individual market insurance plans rather than Medicare, because private plans reimburse at much higher rates. Research from the USC Schaeffer Center found that patients with ESKD accounted for only 0.1% of individual market enrollment but 3.3% of overall spending.
The average monthly spending for an ESKD patient across all healthcare services was $14,399, which is 33 times the spending of patients without ESKD. Shifting even 10% of non-elderly Medicare enrollees with ESKD into the individual market would increase average individual market claims spending by over 4%, potentially raising premiums for all individual market enrollees.
Factors that affect dialysis cost
Several variables influence how much a patient ultimately pays for dialysis. Understanding these factors can help patients make informed decisions about their treatment and coverage options.
| Factor | Impact on cost |
|---|---|
| Type of dialysis | In-center hemodialysis costs more than home or peritoneal dialysis |
| Insurance type | Medicare pays less than private insurance; Medicaid often covers all costs |
| Geographic location | Costs vary by state, region, and urban vs. rural setting |
| Treatment frequency | More frequent or longer sessions increase total cost |
| Medications | Drugs like erythropoietin (EPO) and phosphate binders add to expenses |
| Complications | Hospitalizations from infections or vascular access problems raise costs |
| Transportation | Travel to and from a dialysis center three times per week adds indirect costs |
Geographic location
Dialysis costs vary across the country. Urban areas with more competition among dialysis providers may offer lower prices, while rural areas with limited access can charge more. Medicare adjusts its payment rates by region, but out-of-pocket costs for patients can still differ significantly based on where they live.
Medications and additional services
Dialysis patients often require additional medications, including erythropoiesis-stimulating agents (ESAs), iron supplements, vitamin D analogs, and phosphate binders. Some of these are bundled into Medicare's dialysis payment, while others require separate Part D coverage. Prescription drug costs can add $500 to $2,000 or more per month depending on the patient's medication regimen.
Complications and hospitalizations
Dialysis patients are at higher risk for infections, cardiovascular events, and vascular access complications. Hospitalizations related to these complications add substantially to total healthcare costs. The average ESKD patient's total annual healthcare spending, including non-dialysis medical care, can exceed $90,000 to $170,000. Monitoring kidney health with tools like a kidney ultrasound can help detect issues early, and regular blood work is essential for tracking treatment effectiveness.
Dialysis costs worldwide
Dialysis costs vary dramatically around the world. A study published in the Journal of the American Society of Nephrology compared dialysis reimbursement across 72 countries and found a strong correlation between a country's healthcare expenditure per capita and its dialysis costs.
| Country/region | Estimated annual dialysis cost |
|---|---|
| United States (Medicare) | ~$37,000 – $40,000 |
| Netherlands | ~$89,958 |
| United Kingdom | ~$30,000 – $40,000 |
| Developing nations (e.g., Cameroon) | ~$1,560 |
Interestingly, researchers found that U.S. Medicare dialysis costs are approximately $60,000 per patient less than what would be expected based on overall U.S. healthcare spending levels. This suggests that Medicare's role as the dominant payer has imposed significant cost containment on dialysis, keeping prices lower than they would be in a more fragmented payer system.
Because approximately 85% of U.S. dialysis patients are covered by Medicare, the system functions as a near-single-payer model. This has resulted in dialysis costs that are considerably lower, relative to overall healthcare spending, than what is seen in other high-income countries. Researchers see this as evidence that a dominant payer can effectively control healthcare costs.
Financial assistance for dialysis patients
Several programs exist to help dialysis patients manage their out-of-pocket costs. These range from federal and state programs to nonprofit organizations that provide direct financial aid.
| Resource | Type of help |
|---|---|
| American Kidney Fund (AKF) | Grants to help pay premiums, copays, and medication costs |
| Medicaid | Full or near-full coverage for low-income patients |
| Medigap plans | Cover Medicare's 20% co-insurance and deductibles |
| State kidney programs | Some states offer additional assistance for dialysis patients |
| Dialysis clinic social workers | Help navigate insurance options and financial aid applications |
| Medicare Extra Help (Part D) | Reduces prescription drug costs for qualifying patients |
The American Kidney Fund (AKF) is one of the largest nonprofit providers of financial assistance for dialysis patients. Through its Health Insurance Premium Program and other grants, AKF helps thousands of patients each year cover the costs of insurance premiums, copays, and related expenses.
Patients should also talk with the social worker at their dialysis clinic. These professionals are specifically trained to help patients understand their insurance plans, apply for financial assistance, and navigate the complex system of coverage options available to people with ESKD. For routine doctor visits without insurance, understanding costs upfront can also help with budgeting for overall care.
Frequently asked questions
How much does one dialysis session cost?
A single hemodialysis session costs $250 to $500 on average, though uninsured patients may be billed $500 to $1,000 or more. Under Medicare, the facility reimbursement is approximately $239 per session, plus a monthly physician supervision fee of about $240.
Does Medicare cover dialysis?
