What This Code Means

A pressure ulcer on the right buttock that cannot be staged because the wound characteristics do not fit standard staging criteria.

Coding Tips

  • Unstageable ulcers typically have eschar (dead tissue), slough, or other characteristics preventing accurate stage assessment
  • Document the reason the ulcer cannot be staged in the medical record

Clinical Significance

Unstageable pressure ulcers of the right buttock indicate wound beds obscured by eschar or slough, preventing accurate staging. The right buttock is a primary pressure point in seated patients and supine patients who tend to shift weight to one side. Unstageable wounds require debridement planning to reveal the wound bed and determine the true severity.

Documentation Requirements

  • Anatomical location specified as right buttock
  • Clinical reason for unstageable designation
  • Description of wound covering (eschar characteristics, slough, dressing)
  • Wound dimensions if assessable
  • Patient positioning assessment
  • Debridement plan
  • Monitoring and reassessment schedule
