ICD-10 Code I70.692 – Other atherosclerosis of nonbiological bypass graft(s) of the extremities, left leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.692 – Other atherosclerosis of nonbiological bypass graft(s) of the extremities, left leg
What it is
This code identifies atherosclerotic narrowing or blockage within a nonbiological bypass graft in the left leg. It applies when the graft itself, not the native artery, is affected.
Clinical signs
Findings may include reduced leg perfusion, exertional pain, rest pain, or diminished pulses in the affected limb. Clinical features vary; refer to documentation.
When to use this code
Use I70.692 when the record specifically states atherosclerosis involving a nonbiological bypass graft in the left lower extremity. Code it when the provider documents graft disease rather than disease of the native artery.
Choose this code for laterality-specific documentation of the left leg. If the note only says peripheral arterial disease or graft occlusion without atherosclerosis, check documentation.
Do not use for
Do not use this code for atherosclerosis of native arteries, right leg disease, or unspecified limb laterality. Do not assign it when the graft problem is due to thrombosis, infection, or mechanical failure alone.
Coding tip
Verify that the provider names both atherosclerosis and a nonbiological bypass graft in the left leg before assigning I70.692.
