Non-prs chronic ulc unsp prt of r low leg w necrosis of bone

This code signifies a persistent open sore on the right lower leg, not caused by pressure, that has progressed to involve the underlying bone tissue. The ulceration is chronic, indicating a long-standing condition, and the presence of bone necrosis points to severe tissue damage.

Apply this code when documentation clearly states a non-pressure chronic ulcer on the right lower leg with confirmed necrosis of bone. This typically occurs in patients with underlying conditions like venous insufficiency, arterial disease, or diabetes, where the ulcer has deepened to affect osseous structures.

• Ensure documentation specifies "non-pressure" to differentiate from pressure ulcers.
• Confirm the laterality is "right lower leg" and the depth of involvement includes "necrosis of bone."
• Sequence this code after any underlying systemic conditions contributing to the ulcer (e.g., diabetes mellitus with complications).
