Non-pressure chronic ulcer of back limited to brkdwn skin

This code signifies a persistent skin ulceration on the patient's back that is not caused by pressure. The ulcer involves only the epidermal and dermal layers, indicating a superficial wound without full-thickness tissue loss or involvement of subcutaneous tissue, muscle, or bone. It represents a chronic, non-healing wound on the back.

Apply this code when documentation specifies a chronic, non-pressure ulcer located on the back, and explicitly states that the ulceration is limited to the breakdown of the skin. This typically applies to conditions like venous stasis ulcers, arterial ulcers, or neuropathic ulcers on the back, provided the depth is superficial. Documentation should clearly differentiate it from pressure injuries and indicate the chronicity of the wound.

• Ensure the documentation explicitly states "non-pressure" and specifies the "back" as the anatomical site.
• Verify that the ulcer depth is limited to skin breakdown; avoid using this code for ulcers extending into deeper tissues.
• Differentiate from pressure ulcers (L89.-) and other specified chronic ulcers (L97.-) which involve different etiologies or anatomical sites.
