Pressure ulcer of unspecified buttock, stage 2

This code signifies a partial-thickness skin loss involving the epidermis and/or dermis, presenting as a shallow open ulcer with a red-pink wound bed, without slough. It may also appear as an intact or ruptured serum-filled blister on an unspecified buttock. This stage indicates damage to the skin layers but not yet to underlying tissues.

Apply this code when documentation clearly identifies a pressure ulcer located on either the left or right buttock, and the stage is explicitly documented as Stage 2. This code is appropriate when the specific buttock (left or right) is not specified in the medical record.

• Ensure the documentation explicitly states "Stage 2" and "pressure ulcer" for accurate assignment.
• Do not use this code if the buttock is specified (e.g., left or right); instead, use the more specific L89.312 or L89.322.
• Always sequence this code after any underlying condition that contributed to the pressure ulcer formation, if applicable.
