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

This code signifies the presence of atherosclerosis affecting the native arteries of the patient's left leg, specifically complicated by an ulceration located on a part of the lower leg other than the ankle or heel. This represents a severe manifestation of peripheral artery disease (PAD) with tissue loss.

Use this code when documentation clearly indicates atherosclerosis of the native arteries in the left leg, along with an ulcer that is specifically located on the lower leg (e.g., shin, calf) but not on the ankle or heel. Supporting documentation should include diagnostic findings confirming atherosclerosis and a detailed description of the ulcer's location.

• Ensure the ulcer's location is precisely documented as "other part of lower leg" on the left side, not the ankle or heel.
• Do not confuse with codes for atherosclerosis with gangrene or non-atherosclerotic ulcers.
• Always sequence this code first when it represents the primary reason for the encounter, followed by codes for any associated conditions or complications.
