ICD-10 Code I70.613 – Atherosclerosis of nonbiological bypass graft(s) of the extremities with intermittent claudication, bilateral legs (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.613 – Atherosclerosis of nonbiological bypass graft(s) of the extremities with intermittent claudication, bilateral legs
What it is
This code identifies plaque buildup in a nonbiological bypass graft in the arm or leg arteries, causing reduced blood flow. The claudication is bilateral, meaning symptoms affect both legs.
Clinical signs
Typical findings include exertional leg pain relieved by rest, diminished pulses, and evidence of graft-related arterial narrowing. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents atherosclerosis affecting a nonbiological bypass graft in the extremities and specifically notes intermittent claudication in both legs. You should also confirm the graft is synthetic or otherwise nonbiological, not a vein graft. If laterality is documented as bilateral, do not code only one limb.
Do not use for
Do not use this code for native artery atherosclerosis, unilateral claudication, or bypass graft disease without claudication. Check documentation if the graft type or laterality is unclear.
Coding tip
Verify both the graft material and bilateral symptom documentation before assigning I70.613.
