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

This code signifies a persistent, non-pressure-related open sore located on the left heel or midfoot, characterized by the presence of dead bone tissue. This indicates a severe stage of ulceration where the underlying bone structure has been compromised.

Apply this code when documentation clearly states a chronic ulcer on the left heel or midfoot, explicitly identifying necrosis of the bone as a component of the ulcer. This is typically seen in patients with underlying conditions like diabetes or peripheral vascular disease, leading to severe tissue breakdown.

• Ensure documentation specifies "non-pressure" to differentiate from pressure ulcers.
• Confirm the laterality is "left" and the location is "heel and midfoot."
• Verify that "necrosis of bone" is explicitly stated, not just deep tissue or muscle involvement.
