ICD-10 Code I70.741 – Atherosclerosis of other type of bypass graft(s) of the left leg with ulceration of thigh (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.741 – Atherosclerosis of other type of bypass graft(s) of the left leg with ulceration of thigh
What it is
This code identifies atherosclerotic narrowing or blockage in a nonautologous bypass graft in the left leg, with an associated ulcer on the thigh. Use it when the documentation links the graft disease and the ulcer.
Clinical signs
Findings may include poor limb perfusion, delayed wound healing, and a chronic or nonhealing thigh ulcer. Clinical features vary; refer to documentation for the graft type, laterality, and ulcer site.
When to use this code
Use I70.741 when the provider documents atherosclerosis affecting a bypass graft in the left leg and specifies ulceration of the thigh. It is appropriate for records describing ischemic graft disease with a documented thigh ulcer. If the ulcer location, laterality, or graft type is unclear, check documentation.
Do not use for
Do not use this code for native artery atherosclerosis without a bypass graft, or for ulcers not linked to the graft disease. Do not assign it if the ulcer is on another site or the left leg is not documented.
Coding tip
Code the graft disease and ulcer only when the record clearly connects them; otherwise, query for specificity.
