Pressure ulcer of left upper back, 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 specifically identifies a pressure-induced injury located on the patient's left upper back.

Apply this code when documentation clearly indicates a stage 2 pressure ulcer on the left upper back. This typically presents as a blister (intact or ruptured) or a shallow open ulcer. Supporting documentation should specify the location and the stage of the pressure injury.

• Always confirm the specific anatomical location (left upper back) and the stage (stage 2) from the physician's documentation.
• Distinguish from unstageable pressure ulcers (L89.129) where the wound bed is obscured by slough or eschar.
• Sequence this code after any underlying condition contributing to the pressure ulcer, if applicable.
