ICD-10 Code I70.468 – Atherosclerosis of autologous vein bypass graft(s) of the extremities with gangrene, other extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.468 – Atherosclerosis of autologous vein bypass graft(s) of the extremities with gangrene, other extremity
What it is
This code identifies atherosclerotic narrowing or blockage in an autologous vein bypass graft in an extremity, with gangrene affecting the other extremity. Use it when the record clearly links the graft disease and gangrene.
Clinical signs
Findings may include poor limb perfusion, tissue necrosis, blackened or dead tissue, and diminished pulses. Clinical features vary; refer to documentation for the affected graft and the limb with gangrene.
When to use this code
Use I70.468 when the provider documents atherosclerosis in an autologous vein bypass graft of an extremity and gangrene in the other extremity. Confirm that the graft is autologous vein and that the gangrene is not in the same limb as the graft disease. If the chart does not specify laterality or graft type, check documentation.
Do not use for
Do not use this code for gangrene without documented atherosclerosis of an autologous vein bypass graft, or for prosthetic graft disease. Check documentation if the record describes native artery disease instead.
Coding tip
Verify graft type, extremity laterality, and which limb has gangrene before assigning the code.
