Non-prs chronic ulcer of unsp heel and midfoot w necros bone

This code signifies a persistent, non-pressure-related open sore on an unspecified heel or midfoot that has progressed to involve bone death. It indicates a severe stage of ulceration where the underlying bone structure is compromised due to tissue necrosis.

Apply this code when documentation specifies a chronic, non-pressure ulcer located on either the heel or midfoot, and explicitly states the presence of bone necrosis. This is typically seen in patients with peripheral vascular disease, diabetes, or other conditions leading to poor circulation and tissue breakdown.

• Ensure documentation clearly distinguishes between pressure and non-pressure ulcers.
• Verify the specific anatomical site (heel or midfoot) is not further specified (e.g., right or left).
• Confirm the presence of bone necrosis; superficial necrosis or necrosis of other tissues (e.g., muscle, fat) would require a different code.
