PCREE Testing for In-House Dialysis Units in Skilled Nursing Facilities: What's Different

Dialysis Units Add Two Problems Standard PCREE Programs Aren't Built to Solve

A growing number of skilled nursing facilities now offer in-house or on-site hemodialysis, either through a dedicated treatment room staffed by a contracted dialysis provider or through a small number of stations integrated into the facility. For administrators, it's a meaningful clinical and reimbursement decision. For whoever runs your PCREE program, it introduces two problems that a standard facility-wide inventory usually isn't built to handle: equipment that operates in genuinely wet conditions, and equipment that your facility may not own or directly maintain. For the baseline scope definition this article builds on, see our guide to what equipment requires PCREE testing.

Neither problem is exotic once you name it. But both get missed constantly, because most PCREE walkthroughs are designed around a standard resident room — a bed, a call light, a few portable devices — not a treatment space with standing fluid risk and a piece of equipment that showed up on a truck owned by a company that isn't your PCREE vendor.

Wet Procedure Locations: The Electrical Rule Most Facilities Don't Know Applies

NFPA 99's electrical systems requirements classify certain patient care spaces as wet procedure locations — areas where a routine procedure is likely to produce standing fluids or otherwise wet conditions around patient care equipment. Hemodialysis is a textbook example: the volume of fluid moving through tubing, dialyzers, and drainage lines during a treatment session creates a real possibility of spills or standing liquid on or near the floor where equipment is plugged in.

That classification matters because wet procedure locations generally require additional electrical protection beyond what a standard patient care room needs — typically either an isolated power system or ground-fault circuit interrupter (GFCI) protection on the circuits serving the space, depending on how the room was designed and built. This is a facility electrical systems requirement, evaluated separately from PCREE equipment testing itself. It's worth being precise about the distinction: wet-location protection is about the room's wiring and receptacles, while PCREE testing — leakage current, ground resistance, physical inspection — is about the individual devices plugged into that wiring. A dialysis room can have fully compliant wet-location electrical protection and still have hemodialysis machines that haven't been tested on schedule, or vice versa. Surveyors reviewing the space will look at both.

If your facility built or renovated a dialysis treatment room, your facilities or engineering team should already have documentation showing how the space was designed to meet wet-location requirements. If that documentation isn't readily available, or if the room was repurposed from a different use without an electrical review, that's worth flagging to your facilities lead before your next Life Safety Code survey — independent of anything your PCREE vendor does with the equipment itself.

What Equipment Is In Scope in a Dialysis Unit

A complete PCREE inventory for a dialysis unit needs to capture equipment categories that don't appear anywhere else in the building:

• Hemodialysis machines — the core treatment device, and the piece of equipment most likely to already be on someone's testing schedule, though not necessarily the SNF's.
• Water treatment and reverse osmosis systems — purification equipment that feeds dialysate water, often installed by a specialty water treatment contractor rather than a biomedical vendor.
• Dialysis chairs with powered recline or positioning features — frequently overlooked because they read as furniture rather than patient care electrical equipment.
• Heating and temperature-control components for dialysate or water treatment systems, when powered separately from the main unit.
• Vital signs monitors and scales used during treatment sessions to track fluid removal and patient status.
• Blood leak detectors and ancillary monitoring accessories integrated with or attached to the treatment station.

The test for inclusion is the same one that applies everywhere else in the facility: if the device is powered and used in or around patient care, it's in scope, regardless of who installed it, who owns it, or how specialized it looks. A reverse osmosis water treatment system doesn't stop being PCREE-scoped equipment because a water treatment contractor installed it instead of your biomedical vendor.

Who Owns the Equipment — And Who Owns the Testing?

This is the question that trips up more facilities than the wet-location rule does. Skilled nursing facilities generally arrive at in-house dialysis capability in one of two ways, and the PCREE responsibility looks different depending on which one applies.

Facility-Owned Equipment

If your facility purchased and owns the hemodialysis machines, water treatment system, and supporting equipment outright, responsibility is straightforward: it's on your facility's PCREE program the same as any other equipment in the building, tested on your standard schedule by your biomedical vendor or in-house technician.

Provider-Owned or Provider-Maintained Equipment

Many SNFs that offer in-house dialysis do so through a contracted arrangement with an outside dialysis provider, who supplies and maintains their own hemodialysis machines as part of the service agreement — similar in structure to how some facilities handle other specialized equipment through vendor relationships, a pattern we cover more broadly in our guide to PCREE vendor contracts. In this arrangement, the dialysis provider's own biomedical or clinical engineering program is typically the party actually testing the machines, following its own internal schedule and standards. That doesn't remove the equipment from PCREE scope, and it doesn't remove your facility's exposure if something goes wrong. A CMS surveyor evaluating your facility's electrical safety program isn't going to distinguish between "your equipment" and "the dialysis company's equipment" when touring the space — they're going to expect proof that every powered device in that room has been tested and is documented somewhere.

That means your facility needs a written process for obtaining and retaining the outside provider's testing records for any equipment they own or maintain, reconciled against your facility-wide PCREE inventory so nothing falls into a gap between "we assumed they handled it" and "they assumed we handled it."

Water Treatment Systems Are Their Own Ownership Question

Water treatment and reverse osmosis systems add a third variable, since these are sometimes installed and maintained by a specialty water treatment vendor that is neither your PCREE technician nor the dialysis provider. Before you assume this equipment is covered by someone else's program, confirm in writing who is contractually responsible for its electrical testing — this is exactly the kind of equipment that ends up untested because three different parties each assume it's someone else's job.

Why This Equipment Gets Missed

It Doesn't Show Up on a Standard Biomedical Intake

Equipment brought in by an outside dialysis provider or a specialty water treatment contractor often bypasses the intake process that normally logs new equipment into your facility's PCREE inventory, since it arrives through a clinical services relationship rather than a biomedical equipment purchase.

Nobody Wants to Claim Ownership of the Testing Question

Because responsibility can genuinely sit with three different parties — the facility, the dialysis provider, and a water treatment contractor — it's easy for each to assume one of the others has it covered, and for that assumption to go unchallenged until a survey forces the question.

The Room Reads as "Clinical," Not "Electrical"

A dialysis treatment room is often treated, administratively, as a clinical service line rather than a piece of facility infrastructure, which means it can fall outside the normal walkthrough routine your PCREE vendor uses for the rest of the building.

Documentation and Survey Considerations

When CMS surveyors review a dialysis unit as part of a Life Safety Code survey, they apply the same equipment-related framework used facility-wide — including F689 for accident hazard prevention and F921 for adequacy of the equipment management program, a framework our guide to CMS F-tags and PCREE compliance covers in more depth — while also expecting the room's wet-location electrical protection to be documented separately from equipment testing. Surveyors familiar with dialysis arrangements tend to ask direct questions about who owns which piece of equipment and where the testing records for provider-owned equipment are kept, since "the dialysis company handles that" is not, on its own, an acceptable answer without paperwork behind it.

Strong documentation for a dialysis unit should include a unit-specific equipment inventory that identifies the owner of each device, testing records for facility-owned equipment on your standard PCREE schedule, copies of testing documentation obtained from any outside dialysis provider or water treatment contractor, and a record of the room's wet-location electrical design, maintained by your facilities team. Our guide to electrical receptacle testing in patient rooms covers the receptacle-level testing considerations that apply to wet-location spaces in more detail.

Building a PCREE Testing Plan for Your Dialysis Unit

Start with an ownership audit before you worry about testing schedules: walk through every powered device in the dialysis space and write down who owns it and who is contractually obligated to test it. This single exercise resolves most of the coordination gaps described above, because it forces an explicit answer instead of an assumption.

Next, request and retain testing documentation from any outside dialysis provider or water treatment contractor as a standing condition of the service agreement, not a one-time ask — see our guide to PCREE vendor contracts for language you can adapt when your dialysis or water treatment agreements come up for renewal. Build this into your equipment management plan so the reconciliation happens on a recurring basis rather than only when a survey is imminent.

Finally, confirm separately with your facilities or engineering lead that the room's wet-location electrical protection is documented and current. This isn't something your PCREE vendor will typically address as part of equipment testing, and it's easy for it to fall through the cracks between two teams that each assume the other has it covered.

Frequently Asked Questions

Does dialysis equipment in a skilled nursing facility need PCREE testing?

Yes. Hemodialysis machines, water treatment components, and other powered equipment used in an in-house or on-site dialysis unit meet NFPA 99's definition of patient care-related electrical equipment and fall under the same annual testing, leakage current, and ground resistance requirements as any other PCREE-scoped device in the facility.

Who is responsible for PCREE testing on dialysis machines owned by an outside dialysis provider?

It depends on the service agreement. Many SNFs that offer in-house dialysis contract with an outside dialysis provider who supplies and maintains their own hemodialysis machines. In that case, the provider's biomedical program — not the SNF's PCREE vendor — is typically responsible for testing that equipment, but the SNF still needs documentation proving that testing happened, since a surveyor will hold the facility accountable for the safety of any equipment used in patient care within its walls.

What is a wet procedure location under NFPA 99, and does it apply to dialysis units?

NFPA 99 classifies certain patient care areas as wet procedure locations when a procedure routinely exposes the space to standing fluids or wet conditions. Dialysis stations are commonly treated as wet procedure locations because of the fluid volumes involved in hemodialysis, which means the room's electrical infrastructure — not just the equipment plugged into it — may need additional protection such as isolated power or ground-fault circuit interrupters. This is a facility electrical systems requirement separate from, but related to, PCREE equipment testing.

Does water treatment or reverse osmosis equipment for dialysis need PCREE testing?

If the water treatment system is powered and supports patient care — which reverse osmosis and water purification equipment for dialysis does — it falls within PCREE scope under NFPA 99 and should be included in the facility's equipment inventory and testing schedule, regardless of whether it was installed by a biomedical vendor or a water treatment contractor.

How does an in-house dialysis unit affect CMS survey documentation for PCREE compliance?

Surveyors reviewing a dialysis unit as part of a Life Safety Code survey will expect to see a complete equipment inventory covering every powered device in the space, clear documentation of who tested each piece of equipment and when, and — if an outside provider owns and maintains some of the equipment — records showing the facility obtained and reviewed that provider's testing documentation rather than simply assuming it was done.
