ICD-10 Code I70.793 – Other atherosclerosis of other type of bypass graft(s) of the extremities, bilateral legs (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.793 – Other atherosclerosis of other type of bypass graft(s) of the extremities, bilateral legs
What it is
This code identifies atherosclerotic narrowing or blockage affecting other bypass grafts in both lower extremities. Use it when the documentation specifies bilateral leg graft involvement and does not name a more specific graft type.
Clinical signs
Clinical features vary; refer to documentation. Commonly, notes describe reduced graft patency, diminished limb perfusion, claudication, or other ischemic findings in both legs.
When to use this code
Use I70.793 when the provider documents atherosclerosis of other type of bypass graft(s) in both legs. This is appropriate for postoperative or vascular follow-up notes that identify bilateral lower-extremity graft disease without a more exact code. If the record only says peripheral arterial disease or native-vessel atherosclerosis, check documentation.
Do not use for
Do not use this code for atherosclerosis of native arteries, unilateral graft disease, or graft occlusion without documented atherosclerosis. Check documentation if the bypass graft type or laterality is unclear.
Coding tip
Capture the graft type and bilateral leg involvement exactly as documented before assigning I70.793.
