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

This code signifies a persistent, non-pressure-related open sore on a part of the left foot other than the heel or toes, where the ulceration has progressed to involve the underlying bone tissue, causing bone death. This indicates a severe stage of ulceration, often associated with conditions like peripheral arterial disease or diabetes.

Apply this code when documentation clearly states a chronic, non-pressure ulcer on the left foot (e.g., dorsum, midfoot, plantar arch, excluding heel/toes) with confirmed bone necrosis. Supporting documentation includes imaging reports (X-ray, MRI) confirming osteomyelitis or bone destruction, and physician notes detailing the chronicity and non-pressure etiology.

• Ensure documentation specifies "other part of foot" and not a specific toe or the heel, which have their own codes.
• Confirm the ulcer is chronic and not acute; also, verify it is explicitly non-pressure related.
• Always look for definitive documentation of bone necrosis, not just deep tissue involvement.
