Athscl native arteries of extrm w intrmt claud, left leg

This code signifies the presence of atherosclerosis affecting the native arteries of the left lower extremity, leading to symptoms of intermittent claudication. This condition involves the hardening and narrowing of arteries due to plaque buildup, causing pain, cramping, or weakness in the leg muscles during exercise, which is relieved by rest.

Use this code when documentation explicitly states atherosclerosis of the left leg's native arteries and the patient experiences intermittent claudication. This is typically diagnosed through physical examination, ankle-brachial index (ABI), and imaging studies like duplex ultrasound or angiography.

• Ensure documentation specifies "native arteries" and not bypass grafts or transplanted arteries.
• Confirm the laterality is clearly documented as "left leg" to avoid incorrect coding.
• Distinguish from other forms of peripheral artery disease (PAD) without claudication or with rest pain.
