CMS Conditions for Coverage — End-Stage Renal Disease (ESRD) Dialysis Facilities

End-stage renal disease (ESRD) — the permanent loss of kidney function requiring either dialysis or a kidney transplant to survive — affects over 800,000 Americans, with approximately 560,000 receiving dialysis treatment at any given time. Because Medicare covers ESRD regardless of age (the only disease-specific Medicare entitlement in federal law, enacted in 1972), nearly all dialysis patients receive treatment at facilities that must comply with 42 CFR Part 494 — Conditions for Coverage for End-Stage Renal Disease Facilities. These federal conditions govern every aspect of dialysis facility operations: the quality of the water used to make dialysate, the composition of the clinical team treating each patient, patients' rights to choose their treatment modality (in-center or at home), infection control protocols, quality improvement programs, and emergency preparedness requirements. Meeting these conditions is a prerequisite for Medicare and Medicaid participation and, as a practical matter, determines whether a dialysis facility can operate at all in the United States.

Current Rule (2026)

Key Mechanics

42 CFR Part 494 operates by conditioning Medicare reimbursement on facility compliance with comprehensive clinical and operational standards enforced through CMS survey and certification. Facilities are surveyed initially upon opening and periodically thereafter; deficiencies result in plans of correction, and uncorrected serious deficiencies can lead to Medicare termination. The central organizing mechanism is the interdisciplinary team (IDT) — comprising the patient, a registered nurse, nephrologist, social worker, and dietitian — who jointly develop and monitor individualized care plans. Water quality standards (Subpart C) are the most technically demanding: dialysate used in hemodialysis must meet exacting microbiological and chemical purity limits because patients receive 3 to 12 times their blood volume in dialysate-treated water each treatment session.

Legal Authority

• 42 U.S.C. § 1395rr — Social Security Act § 1881: the ESRD program provision that authorizes CMS to set conditions for ESRD facility participation in Medicare; this is the disease-specific Medicare entitlement enacted in 1972 that covers ESRD regardless of patient age
• 42 CFR Part 494 — CMS implementing regulations covering all aspects of dialysis facility operations: governance, patient rights, staffing qualifications, water quality, infection control, quality improvement, emergency preparedness, and home dialysis

What This Rule Does

Part 494 establishes conditions for coverage — the minimum quality and safety standards a dialysis facility must meet before CMS will reimburse it for treating Medicare ESRD patients. The conditions span the full clinical environment: patient assessment, treatment planning, staffing qualifications, physical plant, water quality, infection control, and patient rights. Unlike many federal regulations that set floors for industry, Part 494 conditions are effectively mandatory for nearly all dialysis providers: without Medicare ESRD certification, a dialysis facility cannot financially survive, because the vast majority of dialysis patients are Medicare-covered.

The central concept is the interdisciplinary team (IDT) — at minimum, the patient (if they choose to participate), a registered nurse, a physician treating the patient for kidney failure, a social worker, and a dietitian — who jointly develop each patient's individualized care plan and monitor outcomes. This team model, which Part 494 places at the center of ESRD care, distinguishes dialysis from many other Medicare-certified settings where physician authority is more dominant.

Key Conditions

Subpart A — General Provisions

• § 494.10 — Definitions: "dialysis facility" includes both independent units and hospital-based outpatient dialysis units; "home dialysis" means dialysis performed at home by a patient or caregiver following training; "self-dialysis" means dialysis with little or no professional assistance by a trained patient

• § 494.20 — Compliance with Federal, State, and local laws and regulations: the facility and its staff must operate in compliance with all applicable law, including state licensure requirements for clinical staff

Subpart B — Patient Safety

• § 494.30 — Infection control: dialysis facilities must maintain a sanitary environment, implement standard infection control precautions (CDC guidance), follow AAMI standards for water quality, and demonstrate documented protocols for managing hepatitis B-positive patients, who must be dialyzed on dedicated machines in a separate room or at a separate time; hepatitis C, HIV, and blood-borne pathogen protocols must be documented and followed

• § 494.40 — Water and dialysate quality: water used to prepare dialysate must meet ANSI/AAMI RD52 standards; chemical and microbiological testing of product water must be conducted at required frequencies; this condition directly affects patient safety — contaminated dialysate has caused mass casualty incidents when trace metals or endotoxins were present

• § 494.50 — Reuse of hemodialyzers and bloodlines: facilities may reuse dialyzers and bloodlines for the same patient (not across patients), following specific processing, labeling, and testing requirements; hepatitis B positive patients are exempt from reuse; reuse is less common than in prior decades but still practiced at some facilities for cost reasons

• § 494.60 — Physical environment: treatment areas must have a minimum of 80 square feet per patient treatment station; adequate lighting, hand-washing facilities at each station, and space for emergency equipment are required; the physical plant must be maintained to ensure patient and staff safety

• § 494.62 — Emergency preparedness: facilities must maintain an emergency plan addressing equipment failures, power outages, water supply interruptions, and natural disasters; dialysis-dependent patients cannot survive extended treatment interruptions — hurricane and flood preparedness for coastal and flood-prone facilities is a critical requirement enforced especially after Hurricane Katrina

Subpart C — Patient Care

• § 494.70 — Patients' rights: each patient has the right to receive dignified care, to choose or refuse any treatment modality (in-center hemodialysis, in-center peritoneal dialysis, home hemodialysis, home peritoneal dialysis), to receive information about each modality, and to designate a representative; facilities must provide patients with written notice of rights when treatment begins; the right to choose home dialysis is specifically protected — facilities cannot pressure patients toward in-center treatment

• § 494.80 — Patient assessment: the interdisciplinary team must provide each patient with a comprehensive assessment within 30 days of admission, covering the adequacy of dialysis (Kt/V urea clearance measurement), nutritional status, mineral metabolism, anemia management (hemoglobin targets), vascular access type and condition, psychosocial needs, and appropriateness of the current treatment modality

• § 494.90 — Patient plan of care: the IDT must develop a written, individualized care plan based on the assessment, including measurable goals and estimated timelines; the plan must be updated when the patient's condition changes and reviewed monthly by the clinical team; the patient (or their representative) must have the opportunity to participate in setting care plan goals

• § 494.100 — Care at home: facilities certified to provide home dialysis must ensure home patients receive care at least equivalent to in-center patients; the IDT must oversee training of both the patient and any caregiver assisting with home dialysis; the training curriculum must cover the specific dialysis modality (peritoneal or hemodialysis), emergency procedures, water treatment system operation (for home hemodialysis), and recognition of access complications

• § 494.110 — Quality assessment and performance improvement (QAPI): facilities must operate a data-driven QAPI program with IDT participation; QAPI programs must include monitoring of clinical performance measures (dialysis adequacy, vascular access infection rates, hospitalizations, mortality), identify performance gaps, and implement corrective actions; CMS uses QAPI documentation as a key compliance indicator during surveys

• § 494.130 — Laboratory services: dialysis facilities must provide or arrange for laboratory services covering all tests needed to monitor ESRD patients (monthly chemistries, hemoglobin, phosphorus, albumin, Kt/V clearance); any laboratory used must meet CLIA certification requirements (42 CFR Part 493)

Subpart D — Administration

• § 494.140 — Personnel qualifications: all staff must meet state scope-of-practice requirements; registered nurses must hold current state licensure; social workers must hold at minimum a master's degree in social work; dietitians must be registered dietitians; patient care technicians must complete state-required training and competency validation (typically BONENT or NNCC certification in states with technician licensure laws)

• § 494.150 — Medical director: every dialysis facility must have a qualified medical director (a physician with board certification in nephrology or equivalent training) who is accountable to the governing body for the quality of medical care; the medical director must ensure all physicians treating patients at the facility meet appropriate qualifications and follow facility policies

• § 494.170 — Medical records: patient records must be complete, accurate, and protected; home patients must have records accessible to the supervising facility; records must be retained for the period required by state law or 5 years from date of service, whichever is longer

• § 494.180 — Governance: the ESRD facility must have an identifiable governing body with full legal authority over facility operations; the governing body must adopt policies on staffing, patient rights, emergency procedures, and quality improvement; corporate-owned dialysis chain facilities (DaVita, Fresenius) must document that their national governance structures satisfy the condition at the facility level

How It Affects You

If you are a patient receiving dialysis: Part 494 guarantees you specific rights — most importantly, the right to be informed about and offered all available treatment modalities. If you want to do home peritoneal dialysis or home hemodialysis, your facility is required to support that choice or assist with your transfer to a facility that can. The QAPI program at your facility generates performance data that CMS uses to compute Dialysis Facility Compare ratings — publicly available at Medicare.gov — allowing you to compare local facilities on clinical quality measures like dialysis adequacy and hospitalization rates.

If you operate or manage a dialysis facility: CMS surveys facilities against Part 494 conditions on an unannounced basis, typically every three years for facilities with good compliance history and more frequently if complaint investigations are triggered. Deficiencies are classified by scope and severity (isolated/pattern/widespread; minimal harm to immediate jeopardy); immediate jeopardy findings require correction within 23 days or result in termination from Medicare. Water quality deficiencies are high-priority because contamination events can harm dozens of patients simultaneously before detection.

If you are a nephrologist or clinic physician: Part 494 requires you to participate in the IDT care planning process for patients you treat at a dialysis facility. The medical director role carries specific regulatory accountability — if a facility receives citation for inadequate patient care, the medical director bears direct responsibility to the governing body. Physicians who contract with dialysis chains should review their employment agreements against Part 494 medical director accountability requirements.

If you are developing or financing a new dialysis facility: the physical plant requirements (80 sq ft per treatment station, emergency equipment, hand-washing stations, emergency preparedness plan) must be incorporated from the design phase. New facilities must complete a CMS certification survey before beginning Medicare billing — the survey process typically takes 90 to 180 days from application submission.

Statutory Authority

This rule implements:

• 42 U.S.C. § 1395rr (Social Security Act § 1881) — the ESRD program authority, which extended Medicare to ESRD patients regardless of age in 1972 and authorizes CMS to establish conditions for coverage of ESRD facilities
• 42 U.S.C. § 1395x(s)(2)(F) — definition of "medical and other health services" covered under Medicare including dialysis

Recent Rulemakings

The 2008 rulemaking (73 FR 20475) was the comprehensive overhaul of Part 494, replacing the prior conditions with the current patient-centered, outcome-focused framework — emphasizing the IDT model, QAPI, and patient rights including the explicit right to choose home dialysis. The 2024 rulemaking (89 FR 89213) added and updated various conditions consistent with the ESRD Treatment Choices (ETC) Model incentives promoting home dialysis and kidney transplantation, and strengthened requirements for patient education on home modalities.
