ICD-10 Code I70.693 – Other atherosclerosis of nonbiological bypass graft(s) of the extremities, bilateral legs (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.693 – Other atherosclerosis of nonbiological bypass graft(s) of the extremities, bilateral legs
What it is
This code identifies atherosclerotic narrowing or blockage in a nonbiological bypass graft supplying both legs. It applies when the graft itself, not the native artery, is affected.
Clinical signs
Clinical features vary; refer to documentation. Patients may have reduced leg perfusion, exertional leg pain, or signs of graft compromise noted on imaging or vascular examination.
When to use this code
Use this code when the provider documents atherosclerosis involving a nonbiological bypass graft in both lower extremities. It may be supported by vascular studies, operative findings, or clear assessment of graft disease. Check documentation for laterality and graft type.
Do not use for
Do not use this code for disease limited to the native leg arteries or for biological grafts. If the record does not clearly state bilateral leg involvement, check documentation.
Coding tip
Confirm both the graft material and bilateral extremity involvement before assigning I70.693.
