Non-prs chronic ulcer oth prt right foot w necrosis of bone

This code signifies a persistent, open sore on a part of the right foot other than the heel, malleolus, or midfoot, that is not caused by pressure. The ulceration has progressed to involve the underlying bone tissue, indicating a severe stage of tissue damage. This condition often arises from underlying vascular insufficiency, neuropathy, or systemic diseases like diabetes.

Use this code for patients presenting with a chronic, non-pressure ulcer located on the right foot (e.g., toes, forefoot, or dorsal/plantar aspects not otherwise specified) where clinical documentation confirms bone necrosis. Supporting documentation should include wound assessments detailing location, chronicity, and imaging or surgical findings confirming bone involvement.

• Ensure documentation clearly specifies "non-pressure" and the exact location on the right foot.
• Always sequence this code after the underlying systemic condition (e.g., diabetes mellitus with foot ulcer, peripheral artery disease) if applicable.
• Distinguish carefully from pressure ulcers (L89.-) and ulcers of specific right foot locations (e.g., L97.41- for heel, L97.31- for ankle/malleolus).
