ICD-10 Code I70.701 – Unspecified atherosclerosis of other type of bypass graft(s) of the extremities, right leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.701 – Unspecified atherosclerosis of other type of bypass graft(s) of the extremities, right leg
What it is
This code identifies atherosclerotic narrowing or blockage in a bypass graft supplying the right leg when the graft type is other than standard categories and the documentation does not specify the exact form of atherosclerosis.
Clinical signs
Clinical features vary; refer to documentation. Findings may include reduced leg perfusion, diminished pulses, claudication, ischemic pain, or graft-related occlusion noted on imaging or vascular assessment.
When to use this code
Use I70.701 when the provider documents atherosclerosis affecting a bypass graft in the right lower extremity and the graft is not described by another more specific code. This is appropriate when the record clearly links the disease to the right leg graft. If the laterality, graft type, or diagnosis is unclear, check documentation.
Do not use for
Do not use this code for native artery atherosclerosis without graft involvement, or for bypass graft disease in another limb. If the chart specifies a different graft type or a more specific atherosclerosis code, use that code instead.
Coding tip
Confirm both the right-leg laterality and that the affected vessel is a bypass graft before assigning I70.701.
