ICD-10 Code I70.612 – Atherosclerosis of nonbiological bypass graft(s) of the extremities with intermittent claudication, left leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.612 – Atherosclerosis of nonbiological bypass graft(s) of the extremities with intermittent claudication, left leg
What it is
This code identifies atherosclerotic narrowing in a nonbiological bypass graft in the left leg. It is used when the graft affects blood flow and causes intermittent claudication.
Clinical signs
Typical findings include exertional leg pain that improves with rest, along with evidence of peripheral arterial disease in the grafted vessel. Clinical features vary; refer to documentation.
When to use this code
Use I70.612 when the provider documents atherosclerosis in a nonbiological bypass graft of the left lower extremity and specifically links intermittent claudication to that limb. The record should support both the graft location and the left-sided claudication. If the note is unclear about the vessel or laterality, check documentation before coding.
Do not use for
Do not use this code for native artery atherosclerosis without a bypass graft, or when claudication is not documented. Do not assume the left leg if laterality is not stated.
Coding tip
Verify graft type, laterality, and the presence of intermittent claudication in the provider’s note before assigning this code.
