Athscl native arteries of extrm w intrmt claud, bi legs

This code signifies the presence of peripheral artery disease (PAD) affecting both lower extremities, specifically due to atherosclerosis of the original, non-grafted arteries. The defining symptom is intermittent claudication, characterized by muscle pain or cramping in the legs that occurs during exercise and is relieved by rest.

Apply this code when documentation clearly indicates bilateral lower extremity atherosclerosis of native arteries, with the patient experiencing exertional leg pain that resolves with rest. This diagnosis is typically supported by physical exam findings, vascular studies (e.g., ankle-brachial index, duplex ultrasound), and patient history.

• Ensure documentation specifies "native arteries" and "bilateral legs" to support this specific code.
• Distinguish from atherosclerosis of bypass grafts (I70.3-I70.7) or unilateral involvement.
• Code any associated risk factors (e.g., hyperlipidemia, diabetes, smoking) as secondary diagnoses.
