ICD-10 Code I70.71 – Atherosclerosis of other type of bypass graft(s) of the extremities with intermittent claudication (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.71 – Atherosclerosis of other type of bypass graft(s) of the extremities with intermittent claudication
What it is
This code identifies atherosclerosis affecting a bypass graft in an extremity, with intermittent claudication. It means the graft has narrowed from plaque buildup, limiting blood flow during activity.
Clinical signs
Typical findings include exertional leg pain that improves with rest, reduced walking tolerance, and evidence of peripheral arterial insufficiency. Clinical features vary; refer to documentation.
When to use this code
Use I70.71 when the record clearly states atherosclerosis in a bypass graft of an arm or leg and intermittent claudication is documented. You should code it when the provider links the claudication to the graft disease. Check documentation if the graft type or symptom relationship is unclear.
Do not use for
Do not use this code for claudication without documented bypass-graft atherosclerosis, or for native-vessel peripheral artery disease alone. Do not assume the graft type or symptom cause; check documentation.
Coding tip
Verify both the bypass graft involvement and the intermittent claudication wording before assigning this code.
