Pressure ulcer of unspecified ankle, 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 or bruising, located on an unspecified ankle. It indicates damage to the skin and underlying tissue due to prolonged pressure, friction, or shear.

Apply this code when documentation clearly identifies a stage 2 pressure ulcer on an ankle, but the specific ankle (left or right) is not specified. This is appropriate for initial encounters or subsequent encounters where the stage remains 2 and the laterality is unknown. Supporting documentation should describe the wound characteristics consistent with a stage 2 pressure ulcer and its anatomical location.

• Ensure the documentation explicitly states "stage 2" and "ankle" for accurate code assignment.
• Avoid using this code if the laterality (left or right ankle) is documented; instead, use the more specific L89.512 or L89.522.
• Always sequence this code after any underlying condition that contributed to the pressure ulcer, such as immobility or diabetes.
