Athscl native arteries of left leg w ulceration oth prt foot

This code signifies the presence of atherosclerosis affecting the native arteries of the left leg, specifically complicated by an ulcer located on a part of the foot other than the heel or midfoot. This condition indicates compromised blood flow due to plaque buildup, leading to tissue breakdown and ulcer formation.

Apply this code when documentation confirms atherosclerotic peripheral artery disease in the left leg with a foot ulcer. The ulcer must be located on the left foot, excluding the heel or midfoot, and directly attributed to the arterial insufficiency. Supporting documentation includes physician notes detailing the diagnosis, location of the ulcer, and its etiology.

• Ensure the documentation specifies "left leg" and "native arteries" to differentiate from bypass grafts or other limbs.
• Verify the exact location of the foot ulcer; codes exist for heel and midfoot ulcers.
• Always sequence this code first if the atherosclerosis is the primary reason for the encounter and the ulcer is a manifestation.
