ICD-10 Code I70.792 – Other atherosclerosis of other type of bypass graft(s) of the extremities, left leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.792 – Other atherosclerosis of other type of bypass graft(s) of the extremities, left leg
What it is
This code identifies atherosclerotic narrowing or blockage affecting a bypass graft in the left leg. It applies when the graft is not an autologous vein graft and the documentation specifies the left lower extremity.
Clinical signs
Clinical features vary; refer to documentation. Findings may include diminished graft patency, reduced limb perfusion, claudication, rest pain, or ischemic changes in the left leg, depending on severity.
When to use this code
Use this code when the record clearly documents atherosclerosis involving an other type of bypass graft in the left leg. The provider should identify both the graft type and the left-sided location. If the note only states peripheral vascular disease or graft disease without these details, check documentation.
Do not use for
Do not use this code for native artery atherosclerosis, right leg disease, or unspecified limb laterality. It is also incorrect if the graft is an autologous vein graft or the chart does not confirm atherosclerotic involvement.
Coding tip
Verify the graft type and laterality in the operative note, vascular study, or assessment before assigning I70.792.
