ICD-10 Code I70.69 – Other atherosclerosis of nonbiological bypass graft(s) of the extremities (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.69 – Other atherosclerosis of nonbiological bypass graft(s) of the extremities
What it is
This code identifies atherosclerotic narrowing or blockage in a nonbiological bypass graft placed in an arm or leg. Use it when the graft itself, not the native vessel, is affected by plaque buildup.
Clinical signs
Clinical features vary; refer to documentation. You may see reduced graft flow, limb ischemic symptoms, diminished pulses, claudication, rest pain, or evidence of graft compromise on imaging or vascular testing.
When to use this code
Use this code when the provider documents atherosclerosis involving a synthetic or other nonbiological bypass graft in an extremity. It applies to graft disease in peripheral arteries of the arms or legs, including follow-up encounters where the diagnosis remains active. Check documentation if the note only describes general peripheral artery disease or native vessel disease.
Do not use for
Do not use it for atherosclerosis of native extremity arteries, biologic grafts, or graft occlusion without documented atherosclerosis. If the record is unclear, check documentation.
Coding tip
Verify that the chart names a nonbiological bypass graft and links the atherosclerosis to that graft before assigning I70.69.
