ICD-10 Code I70.60 – Unspecified atherosclerosis of nonbiological bypass graft(s) of the extremities (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.60 – Unspecified atherosclerosis of nonbiological bypass graft(s) of the extremities
What it is
This code identifies atherosclerotic narrowing or blockage in a nonbiological bypass graft in an arm or leg, when the documentation does not specify the graft site or limb side. Use it for graft disease, not native vessel disease.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include reduced graft patency, diminished distal pulses, limb pain with walking, or signs of poor perfusion in the affected extremity.
When to use this code
Use I70.60 when the record clearly states atherosclerosis involving a nonbiological bypass graft of an extremity and does not identify a more specific site. It is appropriate when the provider documents the condition without laterality or other detail. Check documentation for whether the graft is synthetic or another nonbiologic material.
Do not use for
Do not use this code for atherosclerosis of native arteries, or when the graft is biological rather than nonbiological. If the chart gives a more specific graft location or laterality, code that instead.
Coding tip
Look for the words “bypass graft” and “nonbiological” in the assessment, and code the most specific graft detail documented.
