ICD-10 Code I70.411 – Atherosclerosis of autologous vein bypass graft(s) of the extremities with intermittent claudication, right leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.411 – Atherosclerosis of autologous vein bypass graft(s) of the extremities with intermittent claudication, right leg
What it is
This code identifies atherosclerotic narrowing in an autologous vein bypass graft in the right leg, causing intermittent claudication. Use it when the graft itself is the affected vessel and the symptoms are documented in the right lower extremity.
Clinical signs
Typical findings include exertional leg pain that improves with rest, consistent with intermittent claudication. Clinical features vary; refer to documentation for evidence of graft-related peripheral arterial disease in the right leg.
When to use this code
Use this code when the record states atherosclerosis affects an autologous vein bypass graft in the right leg and claudication is present. It fits postoperative vascular patients with documented graft disease, not just native artery disease. Confirm laterality and graft type in the note.
Do not use for
Do not use this code for atherosclerosis of a native artery, or when the bypass graft type is not autologous vein. If the chart does not specify intermittent claudication or right leg involvement, check documentation.
Coding tip
Verify both the bypass graft material and the laterality before assigning I70.411.
