Athscl native arteries of right leg w ulceration of thigh

This code signifies the presence of peripheral artery disease (PAD) affecting the native arteries of the right leg, specifically complicated by an ulcer located on the thigh. It indicates hardening and narrowing of the arteries due to plaque buildup, leading to impaired blood flow and subsequent tissue breakdown in the specified area.

Apply this code when documentation clearly states atherosclerosis of the right lower extremity's native arteries and explicitly notes an ulceration on the patient's thigh. This is typically seen in patients with chronic PAD experiencing advanced ischemic changes. Supporting documentation would include physician notes detailing the diagnosis, location of the ulcer, and laterality.

• Ensure the documentation specifies "native arteries" and not a bypass graft.
• Verify the ulcer's location is precisely on the "thigh" of the right leg.
• Consider additional codes for associated conditions like diabetes mellitus or gangrene, if present.
