Athscl native art of right leg with ulcer oth prt low leg

This code signifies hardening and narrowing of the arteries in the right leg, specifically the original, non-grafted vessels, which has led to the development of an open sore or lesion on a part of the lower leg other than the ankle or heel. This condition is a manifestation of peripheral artery disease (PAD) where compromised blood flow results in tissue breakdown.

Apply this code when documentation clearly indicates atherosclerosis affecting the native arteries of the right lower extremity, accompanied by an ulcer located on the calf, shin, or other non-ankle/heel region of the lower leg. This code requires explicit mention of both the atherosclerotic disease and the ulceration, specifying the right leg and the native arteries.

• Always confirm laterality (right leg) and the type of arteries (native) are documented.
• Ensure the ulcer location is specified as "other part of lower leg" to differentiate from ankle or heel ulcers.
• Code also any associated risk factors for atherosclerosis, such as diabetes (E11.51) or hyperlipidemia (E78.x).
