ICD-10 Code I70.61 – Atherosclerosis of nonbiological bypass graft(s) of the extremities with intermittent claudication (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.61 – Atherosclerosis of nonbiological bypass graft(s) of the extremities with intermittent claudication
What it is
This code identifies atherosclerotic narrowing in a nonbiological bypass graft in an arm or leg, with intermittent claudication. It describes reduced blood flow that causes exertional leg or limb pain.
Clinical signs
Typical findings include pain, cramping, or fatigue in the affected extremity with walking or other activity, improving with rest. Clinical features vary; refer to documentation.
When to use this code
Use I70.61 when the record specifically documents atherosclerosis involving a nonbiological bypass graft in an extremity and intermittent claudication. The provider should connect the claudication to the graft disease, not only to native vessel 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 atherosclerosis of a nonbiological bypass graft. Do not assign it when the problem is in a native artery, another graft type, or when documentation is insufficient.
Coding tip
Verify both the graft material and the presence of intermittent claudication before coding I70.61.
