Pressure ulcer of unspecified site, stage 3

This code signifies a full-thickness skin and tissue loss due to sustained pressure, where subcutaneous fat may be visible, but bone, tendon, or muscle are not exposed. It typically presents as a deep crater with or without undermining and tunneling.

Apply this code when documentation clearly indicates a pressure ulcer has progressed to Stage 3, characterized by full-thickness tissue loss. This stage involves damage to the subcutaneous tissue but does not extend to muscle, bone, or supporting structures.

• Ensure documentation specifies "Stage 3" and describes the depth of tissue loss to the subcutaneous layer.
• Do not use if bone, tendon, or muscle are exposed; consider higher stages in such cases.
• Always sequence this code after the primary diagnosis or condition leading to the pressure ulcer, if applicable.
