Understanding Dialysis Treatment and Its Costs

Dialysis is a medical treatment that removes waste and extra fluid from the blood when the kidneys no longer work properly. When kidney function drops below 15 percent of normal, dialysis often becomes necessary to keep a person alive. There are two main types of dialysis: hemodialysis and peritoneal dialysis.

Hemodialysis works by filtering blood through a machine called a dialyzer. A surgeon creates an access point, usually in the arm, where needles connect to tubing. Blood flows through the machine, gets cleaned, and returns to the body. Most people receiving hemodialysis go to a treatment center three times per week for about four hours each session. According to the National Kidney Foundation, approximately 371,000 Americans received dialysis treatment in 2021.

Peritoneal dialysis uses the lining of the abdomen to filter blood. A small catheter is surgically placed in the abdomen, and dialysis fluid is introduced through this tube. The fluid sits in the abdomen for a period of time, absorbing waste, then is drained out and replaced with fresh fluid. This type can often be done at home, giving patients more flexibility with their schedule.

The costs associated with dialysis are substantial. A single hemodialysis treatment can cost between $300 and $900, depending on location and facility type. Since most patients receive three treatments weekly, monthly costs can reach between $3,600 and $10,800 before insurance. Annual dialysis care costs in the United States exceed $50 billion. These expenses cover not just the treatment itself but also the facility, medical staff, equipment, and monitoring. When patients understand these baseline costs, they can better navigate insurance options and financial planning.

Practical Takeaway: Learn what type of dialysis treatment involves so you understand what services and costs are connected to your specific situation.

How Medicare Covers Dialysis Treatment

Medicare is the federal health insurance program primarily for people age 65 and older, but it also covers certain younger people, including those with end-stage renal disease (ESRD) requiring dialysis. Medicare coverage for dialysis is one of the program's most significant commitments, reflecting both the critical nature of the treatment and its expense.

Medicare Part B covers dialysis treatments whether they happen at a dialysis center or at home. The program pays for the dialysis procedure itself, the use of the dialysis machine, needles, tubing, and other supplies needed during treatment. Medicare also covers certain lab work and monitoring that dialysis patients need. For patients receiving hemodialysis at a center, Medicare typically covers 80 percent of approved costs after the Part B deductible is met, with patients responsible for the remaining 20 percent coinsurance.

A significant feature of Medicare's dialysis coverage is the "bundle" system. Under this system, most dialysis-related services and medications are bundled into a single payment to the dialysis facility. This means Medicare pays one amount per treatment that covers the treatment, supplies, and most medications. The bundle rate is adjusted annually and varies slightly based on regional factors. In 2024, the base rate for the dialysis bundle is approximately $249 per hemodialysis treatment for most patients.

Medicare also covers vascular access creation and maintenance, which is essential for hemodialysis. Creating the access point in the arm requires surgery, and these procedures are covered. Additionally, Medicare covers some medications given during dialysis, such as erythropoiesis-stimulating agents (ESAs) that help manage anemia in dialysis patients. However, some medications taken outside of dialysis sessions may fall under Medicare Part D prescription drug coverage instead.

One important aspect of Medicare dialysis coverage is that eligibility begins immediately for people with ESRD, regardless of age. A 45-year-old person newly diagnosed with kidney failure and starting dialysis can receive Medicare coverage for dialysis treatment right away, even though Medicare typically doesn't cover people under 65. This reflects the government's recognition that dialysis is life-sustaining treatment.

Practical Takeaway: Medicare covers the majority of dialysis treatment costs for those who meet ESRD criteria, but understanding the bundle system and coinsurance amounts helps you budget for out-of-pocket costs.

Costs You May Still Pay Even With Medicare

While Medicare covers most dialysis treatment costs, patients typically still have significant out-of-pocket expenses. Understanding these remaining costs helps with financial planning and identifying other resources that may help.

The Part B deductible is the first cost threshold. In 2024, the Medicare Part B deductible is $240 annually. Once you meet this deductible, you pay 20 percent coinsurance on Medicare-approved dialysis services. For a patient receiving three dialysis treatments weekly at the current bundle rate, annual coinsurance can total approximately $2,580 (20 percent of roughly $12,900 in annual bundle payments). This is a substantial ongoing expense for many patients.

Medications represent another major cost category. While the dialysis bundle covers some medications given during treatment, other medications that dialysis patients take at home—such as blood pressure medications, phosphate binders, or medications for bone disease—fall under Medicare Part D prescription drug coverage. Patients must pay Part D premiums, deductibles, and copayments for these drugs. Some patients find themselves in the Medicare Part D coverage gap, commonly called the "donut hole," where they must pay a higher percentage of drug costs.

Transportation to dialysis is rarely covered by Medicare. Patients typically need to travel to a treatment center three times weekly. Some dialysis centers offer transportation assistance, and some states have Medicaid programs that cover non-emergency medical transportation, but these programs vary widely. The cost of gasoline, parking, or using ride services for three weekly trips can add up quickly, especially in rural areas where dialysis centers may be farther away.

Supplies and equipment needed at home may have out-of-pocket costs. While Medicare covers supplies used during treatment at a center, patients receiving home dialysis may have some supply-related costs. Additionally, utilities—particularly water usage—increase for patients doing peritoneal dialysis at home.

Copayments for doctor visits and lab work also accumulate. While routine dialysis lab work is bundled into the treatment cost, additional testing or specialty consultations may involve separate copayments. Dialysis patients typically see their nephrologist monthly and may see other specialists for complications, adding to medical costs.

Practical Takeaway: Plan for Medicare deductibles, coinsurance, medications, transportation, and specialist visits as ongoing expenses beyond the dialysis treatment itself—these costs typically total thousands of dollars annually even with Medicare coverage.

Additional Resources Beyond Original Medicare

Dialysis patients have options beyond Original Medicare that may reduce out-of-pocket costs. Understanding these alternatives helps patients make informed decisions about their coverage.

Medicare Advantage plans (Part C) are an alternative to Original Medicare. These plans are offered by private insurance companies approved by Medicare and must cover all services that Original Medicare covers, including dialysis. Many Medicare Advantage plans cover additional services, such as vision, dental, or hearing benefits that Original Medicare does not cover. Some plans may have lower copayments for dialysis services or lower premiums than Original Medicare. However, Medicare Advantage plans often have network restrictions, meaning patients must use dialysis centers within the plan's network or pay higher costs. Because dialysis is a three-times-weekly commitment, patients need to carefully check whether their preferred dialysis center participates in any plan they're considering.

Medicaid works alongside Medicare for those who qualify. When someone has both Medicare and Medicaid (sometimes called "dual eligible"), Medicaid can help pay Medicare premiums, deductibles, and coinsurance. Medicaid eligibility varies by state—some states are more restrictive about income and asset limits while others are more generous. A dialysis patient in one state might qualify for Medicaid while the same patient in another state would not. Contacting your state Medicaid office provides information about eligibility in your specific location.

The National Kidney Foundation (NKF) and American Kidney Fund (AKF) are non-profit organizations that provide financial assistance to dialysis patients. The American Kidney Fund operates a patient financial assistance program that may help with costs such as Medicare premiums, deductibles, copayments, and transportation. The National Kidney Foundation offers various support programs and may have local chapters that connect patients with resources. These organizations also provide educational
