L97.821
ICD-10-CMNon-pressure chronic ulcer of other part of left lower leg limited to breakdown of skin
This code signifies a persistent, non-pressure-related ulcer located on a part of the left lower leg other than the ankle or foot, where the tissue damage is confined to the epidermal and dermal layers. This indicates a superficial ulceration that has not penetrated deeper tissues.
Apply this code when documentation specifies a chronic, non-pressure ulcer on the left lower leg (e.g., calf, shin) with involvement limited to the skin. This is appropriate for conditions like venous stasis ulcers or arterial ulcers that have not progressed beyond the skin layers. Documentation should clearly state "chronic," "non-pressure," "left lower leg," and "breakdown of skin" or similar terminology indicating superficial depth.
