Athscl native arteries of extrm w intrmt claud, right leg

This code signifies a hardening and narrowing of the native arteries in the right leg due to plaque buildup, leading to symptomatic pain and cramping in the leg muscles during exercise (intermittent claudication). It indicates a specific manifestation of peripheral artery disease (PAD) affecting the lower extremity.

This code is appropriate when documentation clearly states atherosclerosis of the native arteries in the right leg and explicitly mentions intermittent claudication as a symptom. It is used for patients experiencing activity-induced leg pain that resolves with rest, attributable to arterial insufficiency in the right lower limb.

• Ensure the documentation specifies "native arteries" and not a bypass graft.
• Laterality (right leg) is crucial for accurate code assignment.
• Distinguish from rest pain, which would indicate a more severe stage of PAD.
