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

This code signifies a persistent open sore on a part of the right lower leg, excluding the ankle or foot, that is not caused by pressure. The ulceration has progressed to involve the underlying bone tissue, indicating severe tissue destruction. This condition often arises from underlying vascular insufficiency, neuropathy, or other systemic diseases.

Apply this code when documentation specifies a chronic, non-pressure ulcer located on the right lower leg (e.g., calf, shin) with confirmed necrosis of the bone. This typically requires imaging studies (e.g., X-ray, MRI) or surgical findings to substantiate bone involvement. Use for ulcers that have been present for an extended period and are not healing.

• Ensure documentation clearly distinguishes between pressure and non-pressure ulcers.
• Verify the specific anatomical location on the right lower leg and the presence of bone necrosis.
• Always code the underlying cause of the ulcer (e.g., peripheral artery disease, diabetes) as a primary or secondary diagnosis.
