ICD-10 Code I70.745 – Atherosclerosis of other type of bypass graft(s) of the left leg with ulceration of other part of foot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.745 – Atherosclerosis of other type of bypass graft(s) of the left leg with ulceration of other part of foot
What it is
This code identifies atherosclerotic narrowing or blockage affecting a nonautologous bypass graft in the left leg, with an associated ulcer on another part of the foot. It tells you both the graft location and the presence of ulceration.
Clinical signs
Clinical features may include reduced limb perfusion, diminished pulses, pain, or delayed wound healing. The ulcer should be documented on the foot, and clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents atherosclerosis in a bypass graft of the left leg and also documents an ulcer of another part of the foot. The ulcer location should match the record, and the vascular graft involvement must be specified. If the graft type or ulcer site is unclear, check documentation.
Do not use for
Do not use this code for native artery disease without graft involvement or for ulcers not linked to the documented bypass graft condition. Do not assign it when the left-leg graft or foot ulcer is not specifically documented.
Coding tip
Verify both laterality and ulcer site in the note before assigning I70.745.
