K-Tags Explained: Life Safety Code Deficiencies on CMS Surveys

K-tags are the numbered Life Safety Code deficiency categories CMS surveyors use on the Form CMS-2786 Life Safety survey reports. Each K-tag maps to a section of NFPA 101 or NFPA 99, and a citation under a K-tag appears on the Statement of Deficiencies alongside the health survey findings.

Understanding the K-tag structure helps a facilities team organize documentation, predict what the surveyor will ask for and respond to citations with a plan of correction that addresses the right requirement.

How K-tags are organized

  • K100 series: general building and construction requirements
  • K200 series: means of egress, corridors, exits, doors and illumination
  • K300 series: protection, including hazardous areas, vertical openings, fire alarm, sprinklers and fire barriers
  • K500 series: building services such as HVAC, elevators and utilities
  • K700 series: operating features including fire drills, smoking, combustible decorations and emergency plans
  • K900 series: NFPA 99 Health Care Facilities Code items including medical gas, electrical systems and emergency power

K-tags cited most often

  • K211 Means of egress: corridor obstructions and egress clearance
  • K222 Egress doors: locking arrangements and hardware

  • K291 Emergency lighting: monthly and annual tests

Responding to a K-tag citation

Each K-tag on the Statement of Deficiencies needs a specific corrective action, a responsible person, a completion date and the monitoring that prevents recurrence. The best responses correct the underlying process, not just the single door or missing log entry the surveyor found.
