ICD-10 Code I25.711 – Atherosclerosis of autologous vein coronary artery bypass graft(s) with angina pectoris with documented spasm (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.711 – Atherosclerosis of autologous vein coronary artery bypass graft(s) with angina pectoris with documented spasm
What it is
This code identifies atherosclerotic narrowing in an autologous vein coronary bypass graft, with angina and documented coronary spasm. Use it when the graft is the diseased vessel and the spasm is specifically documented.
Clinical signs
Patients may have chest pain or pressure consistent with angina, often triggered by exertion or vasospasm. Clinical features vary; refer to documentation for evidence of graft disease and documented spasm.
When to use this code
Use this code when the provider documents atherosclerosis in a vein graft used for coronary bypass, along with angina pectoris and documented spasm. It applies to postoperative patients with a prior autologous vein CABG, not native coronary disease. Verify the graft type and the presence of spasm in the record.
Do not use for
Do not use it for native coronary atherosclerosis, graft disease without angina, or spasm that is not documented. Check documentation if the bypass conduit is not an autologous vein.
Coding tip
Code only when the record clearly links the angina and spasm to the autologous vein bypass graft.
