ICD-10 Code I70.708 – Unspecified atherosclerosis of other type of bypass graft(s) of the extremities, other extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.708 – Unspecified atherosclerosis of other type of bypass graft(s) of the extremities, other extremity
What it is
This code identifies atherosclerotic narrowing or blockage in a bypass graft in an extremity when the graft type is other than the standard categories and the affected limb site is not further specified. Use it when the record documents atherosclerosis of the graft, but details are limited.
Clinical signs
Findings may include reduced limb perfusion, diminished pulses, claudication, or ischemic pain, depending on the graft location. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents atherosclerosis involving an other-type bypass graft in an arm or leg and does not name a more specific extremity site. It is also appropriate when the chart states the condition as unspecified atherosclerosis of the graft. Check documentation if the graft type or limb laterality is unclear.
Do not use for
Do not use this code for native artery atherosclerosis or for bypass graft disease in the aorta, coronary vessels, or other non-extremity sites. Do not assign it when the record identifies a more specific graft type or extremity location.
Coding tip
Verify that the documentation supports both bypass graft involvement and an extremity location before assigning I70.708.
