Pressure ulcer of left lower back, stage 2

This code identifies 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 as an intact or ruptured serum-filled blister, located on the left lower back. It signifies damage to the skin and underlying tissue resulting from prolonged pressure.

Apply this code when documentation clearly indicates a stage 2 pressure ulcer situated specifically on the patient's left lower back. This includes scenarios where the ulcer is described as a blister, abrasion, or shallow crater. Ensure the medical record specifies both the anatomical location and the ulcer stage.

• Always confirm both the specific anatomical site (left lower back) and the ulcer stage (stage 2) from the provider's documentation.
• Differentiate stage 2 from stage 1 (non-blanchable erythema) and stage 3 (full-thickness skin loss with visible subcutaneous fat).
• Sequence this code as a secondary diagnosis when the pressure ulcer is a complication of another underlying condition.
