ICD-10 Code I70.619 – Atherosclerosis of nonbiological bypass graft(s) of the extremities with intermittent claudication, unspecified extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.619 – Atherosclerosis of nonbiological bypass graft(s) of the extremities with intermittent claudication, unspecified extremity
What it is
This code identifies atherosclerotic narrowing in a nonbiological bypass graft in an extremity, causing intermittent claudication. Use it when the graft is involved and the affected limb is not specified.
Clinical signs
Patients typically report exertional leg pain or cramping that improves with rest. Documentation should support peripheral arterial disease in the bypass graft; clinical features vary, refer to documentation.
When to use this code
Use I70.619 when the provider documents atherosclerosis affecting a synthetic or other nonbiological bypass graft in an arm or leg, with intermittent claudication. The record must also indicate that the extremity is unspecified. If the note names the limb, choose the more specific code.
Do not use for
Do not use this code for native-vessel atherosclerosis without graft involvement, or for claudication without documented graft disease. Check documentation if the graft type or limb laterality is unclear.
Coding tip
Confirm both the graft material and the presence of intermittent claudication before assigning this code.
