ICD-10 Code I70.608 – Unspecified atherosclerosis of nonbiological bypass graft(s) of the extremities, other extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.608 – Unspecified atherosclerosis of nonbiological bypass graft(s) of the extremities, other extremity
What it is
This code identifies atherosclerotic narrowing or blockage in a nonbiological bypass graft in an extremity when the affected limb is the other extremity and the record does not specify the exact site. Use it when documentation confirms graft disease but lacks more detail.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include reduced limb perfusion, claudication, diminished pulses, or graft-related ischemic symptoms, but the code itself depends on documented atherosclerosis of the bypass graft.
When to use this code
Use I70.608 when the provider documents atherosclerosis involving a nonbiological bypass graft in an extremity and specifies the “other extremity,” but not a more precise limb segment. It also fits when the chart confirms graft atherosclerosis without laterality detail beyond that term. Check documentation if the graft is biological or the issue is stenosis from another cause.
Do not use for
Do not use this code for native artery atherosclerosis, acute graft occlusion, or complications unrelated to atherosclerotic disease. If the record describes a different graft type or a more specific extremity site, code that documented condition instead.
Coding tip
Confirm both the graft type and the exact extremity wording in the note before assigning I70.608.
