Pressure ulcer of unspecified part of back, stage 2

This code represents 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 indicates a pressure ulcer located on an unspecified part of the patient's back.

Use this code when documentation clearly identifies a Stage 2 pressure ulcer located on the back, but the specific anatomical site (e.g., sacrum, coccyx) is not specified. Supporting documentation should describe the wound characteristics consistent with a Stage 2 pressure injury.

• Ensure the documentation explicitly states "Stage 2" and "back" for accurate code assignment.
• Avoid using this code if a more specific anatomical site on the back (e.g., sacrum, coccyx, scapula) is documented; instead, use the appropriate L89.11-L89.15- code.
• Always code the highest stage of a pressure ulcer if multiple stages are present at the same site.
