Non-prs chronic ulcer oth prt l low leg w necrosis of bone

This code signifies a persistent ulceration on a part of the left lower leg, excluding those caused by pressure, that has progressed to involve necrosis of the underlying bone. This indicates a severe, deep tissue injury often associated with compromised circulation or neuropathy.

Apply this code when documentation specifies a chronic, non-pressure ulcer located on the left lower leg, and explicitly states the presence of bone necrosis. This is typically seen in patients with advanced peripheral arterial disease, diabetes, or other conditions leading to chronic wounds with deep tissue destruction.

• Ensure documentation clearly specifies "non-pressure" to differentiate from pressure ulcers.
• Verify the laterality (left lower leg) and the specific tissue involvement (necrosis of bone).
• Always code any underlying systemic conditions, such as diabetes mellitus or peripheral vascular disease, as additional diagnoses.
