ICD-10 Code I70.211 – Atherosclerosis of native arteries of extremities with intermittent claudication, right leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.211 – Atherosclerosis of native arteries of extremities with intermittent claudication, right leg
What it is
This code identifies atherosclerotic narrowing of the native arteries in the right leg that causes intermittent claudication. Use it when the record documents exertional leg pain from peripheral arterial disease on the right side.
Clinical signs
Typical findings include leg pain or cramping with walking that improves with rest, along with evidence of peripheral arterial disease. Clinical features vary; refer to documentation.
When to use this code
Use I70.211 when the provider documents atherosclerosis of native arteries in the right lower extremity and specifically links it to intermittent claudication. It is appropriate for right-leg disease only, not bilateral or unspecified limb involvement. Check documentation if the laterality or symptom is unclear.
Do not use for
Do not use this code if claudication is absent or if the record describes another limb, bilateral disease, or unspecified extremity. Do not assign it for acute limb ischemia or nonatherosclerotic vascular disease.
Coding tip
Confirm both laterality and the presence of intermittent claudication in the provider note before assigning I70.211.
