Non-prs chronic ulcer of r forearm with necrosis of bone

This code signifies a persistent, non-pressure-related open sore on the right forearm that has progressed to involve the underlying bone tissue, indicating bone death. It describes a severe stage of ulceration not caused by sustained pressure.

Apply this code when documentation clearly states a chronic, non-pressure ulcer on the right forearm with confirmed osteonecrosis. This is typically seen in patients with underlying conditions like diabetes, peripheral vascular disease, or autoimmune disorders. Documentation should specify the location, chronicity, and the presence of bone necrosis.

• Ensure the documentation specifies "non-pressure" to differentiate from pressure ulcers.
• Verify the laterality (right forearm) and the specific tissue involvement (necrosis of bone).
• Always sequence this code after the underlying cause of the ulcer, if known (e.g., diabetes with complications).
