ICD-10 Code I25.712 – Atherosclerosis of autologous vein coronary artery bypass graft(s) with refractory angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.712 – Atherosclerosis of autologous vein coronary artery bypass graft(s) with refractory angina pectoris
What it is
This code identifies atherosclerotic narrowing or blockage in an autologous vein coronary artery bypass graft, with angina that persists despite treatment. Use it when the graft itself is the documented site of disease.
Clinical signs
Patients may have ongoing chest pain or ischemic symptoms after CABG, often with evidence of graft disease on imaging or catheterization. Clinical features vary; refer to documentation.
When to use this code
Use I25.712 when the record states atherosclerosis affects an autologous vein bypass graft and the patient has refractory angina pectoris. You should code it only when the graft type and persistent angina are clearly documented. Check documentation if the provider describes coronary disease without specifying graft involvement.
Do not use for
Do not use this code for native coronary artery atherosclerosis, nonrefractory angina, or graft disease involving a nonautologous conduit. If the chart does not confirm refractory angina, choose a different code.
Coding tip
Verify both the graft type and the word “refractory” in the assessment before assigning I25.712.
