ICD-10 Code I70.41 – Atherosclerosis of autologous vein bypass graft(s) of the extremities with intermittent claudication (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.41 – Atherosclerosis of autologous vein bypass graft(s) of the extremities with intermittent claudication
What it is
This code identifies atherosclerotic narrowing or blockage in an autologous vein bypass graft in an extremity, with intermittent claudication. Use it when the graft itself is the site of disease, not the native artery.
Clinical signs
Typical findings include exertional leg pain that improves with rest, reduced walking tolerance, and evidence of peripheral arterial disease affecting a bypass graft. Clinical features vary; refer to documentation.
When to use this code
Use I70.41 when the record clearly states atherosclerosis of an autologous vein bypass graft in an arm or leg and documents intermittent claudication. The provider may describe graft stenosis, occlusion, or ischemic symptoms tied to exertion. Check documentation if the affected vessel or symptom pattern is unclear.
Do not use for
Do not use this code for atherosclerosis of native arteries, prosthetic grafts, or bypass graft disease without intermittent claudication. If the documentation does not identify an autologous vein graft, check documentation.
Coding tip
Verify both the graft type and the presence of intermittent claudication before assigning I70.41.
