ICD-10 Code I70.748 – Atherosclerosis of other type of bypass graft(s) of the left leg with ulceration of other part of lower leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.748 – Atherosclerosis of other type of bypass graft(s) of the left leg with ulceration of other part of lower leg
What it is
This code identifies atherosclerosis affecting a nonautologous bypass graft in the left leg, with a documented ulcer on another part of the lower leg. Use it when the graft disease and ulcer location are both specified.
Clinical signs
Findings may include reduced limb perfusion, diminished pulses, graft narrowing or occlusion, and a chronic ulcer on the lower leg. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states atherosclerosis of an other type of bypass graft in the left leg and also documents ulceration of another lower-leg site. You need both the graft-related atherosclerosis and the ulcer detail. Check documentation if the graft type, laterality, or ulcer location is unclear.
Do not use for
Do not use this code for native artery atherosclerosis without a bypass graft, or for ulcers without documented atherosclerosis of the graft. Check documentation if the ulcer is on a different body site.
Coding tip
Confirm the graft type, left-sided location, and ulcer site before assigning I70.748.
