ICD-10 Code I70.213 – Atherosclerosis of native arteries of extremities with intermittent claudication, bilateral legs (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.213 – Atherosclerosis of native arteries of extremities with intermittent claudication, bilateral legs
What it is
I70.213 identifies atherosclerotic narrowing in the native arteries of both legs with intermittent claudication. Use it when documentation shows peripheral arterial disease affecting bilateral lower extremities.
Clinical signs
Typical findings include leg pain or cramping with walking that improves with rest, plus evidence of arterial insufficiency in both legs. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents atherosclerosis of native lower-extremity arteries and specifically states intermittent claudication in both legs. It also fits vascular evaluations, follow-up visits, or problem lists when the bilateral leg involvement is clear.
If the record says only one leg, use the unilateral code instead. Check documentation when laterality or the presence of claudication is not explicit.
Do not use for
Do not use it for atherosclerosis without claudication, for bypass graft disease, or when the condition involves only one leg. Do not assume bilateral disease without documentation.
Coding tip
Confirm both “native arteries” and “bilateral legs” are documented before assigning I70.213.
