Pressure ulcer of unspecified buttock, stage 3

This code signifies a full-thickness skin and tissue loss involving damage or necrosis of subcutaneous tissue, which may extend down to, but not through, underlying fascia, on an unspecified buttock. It presents as a deep crater with or without undermining or tunneling of adjacent tissue.

Apply this code when documentation clearly indicates a pressure ulcer located on the buttock, and the wound depth is classified as Stage 3. This requires physician documentation specifying the stage and anatomical location.

• Ensure the documentation explicitly states "Stage 3" and "buttock" for accurate assignment.
• Do not use if the ulcer extends to muscle, bone, or supporting structures; consider Stage 4 codes.
• Always sequence this code after any underlying condition causing the pressure ulcer, if applicable.
