Non-pressure chronic ulcer of back with unspecified severity

This code signifies a persistent open sore on the patient's back that is not caused by pressure. It indicates a long-standing ulceration of the skin and underlying tissue in the dorsal region, where the severity of the ulcer (e.g., stage) has not been documented.

Apply this code when documentation clearly identifies a chronic, non-pressure ulcer located on the back. This is appropriate when the physician's notes confirm the ulcer's chronicity and location, but do not specify the depth or stage of tissue involvement.

• Always seek clarification from the provider if the severity or stage of the ulcer is not documented, as more specific codes exist.
• Do not use this code for pressure ulcers; refer to the L89 category for those conditions.
• Sequence this code after any underlying systemic conditions contributing to the ulcer, such as diabetes with complications.
