Pressure ulcer of left 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 the left ankle. It may also manifest as an intact or ruptured serum-filled blister.

Apply this code when documentation clearly indicates a stage 2 pressure ulcer affecting the left ankle. This typically involves a physical examination noting the characteristic partial-thickness skin loss or blister formation in this specific anatomical location.

• Ensure the documentation explicitly states "stage 2" and specifies the "left ankle" to support this code.
• Differentiate from stage 1 (non-blanchable erythema) and stage 3 (full-thickness skin loss with visible subcutaneous fat).
• Always sequence the pressure ulcer code after any underlying condition causing the pressure ulcer (e.g., immobility due to fracture).
