L97.421
ICD-10-CMNon-pressure chronic ulcer of left heel and midfoot limited to breakdown of skin
This code signifies a chronic, non-pressure-related ulcer located on the left heel or midfoot, where the tissue damage is confined to the epidermis and/or dermis. It indicates an open sore that has persisted over time, not caused by sustained pressure, and has not progressed beyond the superficial skin layers.
Apply this code when documentation specifies a chronic ulcer on the left heel or midfoot, explicitly stating it is non-pressure-related and limited to skin breakdown. Supporting documentation would include physician notes detailing the ulcer's location, chronicity, etiology (e.g., venous insufficiency, arterial insufficiency, neuropathic), and the depth of tissue involvement.
