Non-prs chronic ulcer oth prt l low leg w fat layer exposed

This code signifies a persistent ulceration on the left lower leg, excluding those caused by pressure, where the subcutaneous fat tissue is visible. It indicates a deeper wound that has progressed beyond the epidermal and dermal layers. This condition often arises from underlying vascular insufficiency, neuropathy, or trauma.

Apply this code when documentation specifies a chronic, non-pressure ulcer located on the left lower leg, and the wound depth clearly exposes the fat layer. This code is appropriate for ulcers that are not healing within a typical timeframe and are not attributed to immobility or sustained pressure. Supporting documentation should detail the chronicity, location, and depth of the ulcer.

• Always confirm the laterality (left leg) and the specific depth of the ulcer (fat layer exposed).
• Differentiate from pressure ulcers (L89.-) and acute ulcers, which would be coded differently.
• Sequence this code after any underlying systemic conditions contributing to the ulcer, such as diabetes (E11.621) or peripheral vascular disease (I70.2-).
