If your facility's CMS-2567 has ever listed K921, you already know it has to do with electrical equipment. Many administrators don't realize that K921 is the Life Safety Code tag for patient care-related electrical equipment (PCREE) testing. It is where gaps in your PCREE program show up on a survey report.

By the numbers: From September 2023 to August 2026, CMS data shows 1,345 nursing homes were cited under K921 (1,563 citations). Washington (215), Indiana (211) and Iowa (166) surveyors issued the most. See every state.

What K921 Covers

K921 is titled "Electrical Equipment – Testing and Maintenance Requirements." On published survey reports, the tag text says that the physical integrity, resistance, leakage current and touch current tests for fixed and portable PCREE are performed as required in NFPA 99 section 10.3, and that all PCREE used in patient care rooms is tested before being put into service. It also points to NFPA 99 section 10.5, which covers the facility's testing program, manufacturer service information and record keeping.

In plain terms, K921 asks three questions:

  • Was the equipment tested? Physical inspection, ground resistance and leakage current, at the interval your program sets.
  • Was new or returned equipment tested before use? This includes new purchases, rentals, loaners and devices back from repair.
  • Can you prove it? Records that tie each device to a test date, results and the person who did the work.

Why SNFs Get Cited Under K921

Most K921 citations are documentation problems rather than dangerous equipment. The patterns we see most often:

  • Testing lapsed. The vendor relationship ended, the maintenance director changed, and nobody scheduled the next round.
  • Incomplete inventory. Beds and lifts were tested, but monitors, oxygen concentrators or newer equipment were missed.
  • No incoming testing. A rental bed, hospice-supplied equipment or a new purchase went into a resident room with no test record. See testing new, rental and loaner equipment.
  • Summary-only reports. The vendor left a one-page "all passed" letter instead of device-level results.
  • Failures never closed out. A device failed, but there's no record that it was repaired and re-tested. See post-repair testing requirements.

What Surveyors Ask to See

Expect the Life Safety Code surveyor to ask for your most recent PCREE test records and then spot-check them. A common approach is to pick a bed or lift in a resident room and ask you to find its record. Have these ready in one place:

  1. Your current PCREE inventory, with asset ID and location for each device
  2. The most recent device-level test report, with measured values
  3. Corrective action records for any failures, including re-tests
  4. Incoming test records for equipment added since the last full round
  5. Your written testing policy or equipment management program, including intervals
  6. Technician qualification documentation and the test instrument's calibration record

If You've Already Been Cited

A K921 deficiency needs a plan of correction that fixes the problem and shows how it won't recur. In practice that means: complete testing of all PCREE (not just the devices the surveyor flagged), document results at the device level, put an incoming-equipment testing step into your receiving process, and assign a named person to track the next due date. Our guide to responding to a PCREE deficiency walks through the plan of correction in more detail.

Frequently Asked Questions

What is a K921 citation?
K921 is the CMS Life Safety Code tag titled Electrical Equipment – Testing and Maintenance Requirements. Surveyors cite it when a facility cannot show that patient care-related electrical equipment was tested as required by NFPA 99, including testing of new or returned equipment before use and the related records.
Is K921 the same as an F-tag?
No. K-tags come from the Life Safety Code survey, which focuses on the building, fire safety and electrical systems. F-tags come from the health survey. A PCREE problem is usually cited under K921, though related equipment issues can also appear on the health survey.
What is the fastest way to correct a K921 deficiency?
Schedule complete PCREE testing of all equipment, get a device-level report with measured values, close out any failures with repairs and re-tests, add incoming testing for new and rental equipment, and assign a person to track the next due date. Document each step for your plan of correction.
