Kidney Dialysis Center Revenue Benchmark

Average Dialysis Center Revenue per Year 2022 Economic Census

The 2022 Economic Census counts every freestanding kidney dialysis center with paid employees and publishes their combined annual receipts. Dividing that total by the number of centers gives the average annual revenue per employer establishment shown below.

≈$3,591,000 /year

Average annual gross revenue per employer establishment

How this is calculated: about $29.9 billion in combined annual receipts divided by 8,335 employer establishments works out to an average annual revenue of $3,591,000 per employer establishment.

Scope: Kidney dialysis centers, NAICS 621492. The category covers freestanding kidney dialysis centers. Dialysis units inside hospitals and physician offices are counted with those establishments. Classified separately in group 6214: 621410 Family Planning Centers; 621420 Outpatient Mental Health and Substance Abuse Centers; 621491 HMO Medical Centers, and 2 further codes.

Employer Establishments at Year Five Endpoint only

Outpatient Care Centers, NAICS 6214, the 2018 starting count compared with the count of five-year-old establishments in 2023.

Across the 2014 to 2018 cohorts, five-year results ranged from 65.3 to 81.9 percent. This benchmark covers Outpatient Care Centers, NAICS 6214, as a whole, and this category accounts for 8,335 of the 57,177 employer establishments in it. A count by age is not a survival rate, because the figures compare two headcounts rather than follow one set of businesses.

Payroll as a Share of Revenue Official data

Payroll divided by receipts, both as published for the same year.

Payroll share of receipts, Kidney dialysis centers, United States, 2022 Economic Census.

Approximately 25.0 percent of every revenue dollar goes to annual payroll, a modest share for a clinical service because dialysis machines, supplies and medications carry a large part of each treatment alongside nurses and technicians.

Payroll here excludes benefits, employer taxes and owner compensation, and it excludes machines, dialyzers, medications, water treatment systems and physician fees billed separately, which together carry much of what a center spends.

Business Scale and Ownership Structure Official data

How large the average establishment is, and whether the population is independent operators or multi-site companies.

Scale and ownership, Kidney dialysis centers, United States, 2022 Economic Census.

The average establishment employed about 17.2 people, and the industry averaged 16.1 employer establishments per firm, which confirms that multi-establishment ownership exists in the published population without showing how establishments are distributed across firms. As an illustration, that headcount could be nurses, patient care technicians and a facility team for a set number of chairs; the establishments per firm figure sits far above most categories on this site, which points to multi-site operators without showing what share of centers they run.

These are arithmetic industry averages. They state the size of the average establishment and show that multi-establishment ownership exists. They do not show the distribution of business sizes and they do not measure market concentration.

Questions Worth Asking BusinessNES analysis

Kidney Dialysis Center: what payer rules, chair capacity and a chain-dominated category do to the average.

Before you rely on this benchmark

• Who owns the center? The ownership table above shows how heavily this category is concentrated in companies running many centers, so the average reflects large-chain economics. An independent center should not expect the same purchasing, staffing or payer leverage.
• How are treatments paid? Medicare covers a large share of dialysis patients and pays under a bundled rate that includes drugs and supplies, while commercial insurers pay more per treatment for a smaller share of patients. Payer mix decides revenue per treatment far more than chair count does.
• How full are the chairs? A center's capacity is chairs multiplied by shifts, and each patient occupies a chair on a fixed schedule for years. Chair and shift utilization is the number a center is run on, and an annual total cannot reveal it.
• What does the clinical staffing require? Nurses, patient care technicians, dietitians and social workers form the staffing that federal conditions of coverage expect, with ratios that vary by state, and a medical director oversees care. Staffing rules in some states and payer conditions put a floor under payroll regardless of volume.
• Where does home dialysis fit? Home dialysis programs shift treatments out of the chair and change how a center earns and staffs, and payers have encouraged the shift. A center's home program share is not visible in the average.
• What does the plant cost? Water treatment, machines, reuse systems and infection control build-out are heavy fixed costs specific to dialysis, and they must be maintained and replaced. Capital per chair sits outside a receipts figure.
