ICD-10 Code I25.718 – Atherosclerosis of autologous vein coronary artery bypass graft(s) with other forms of angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.718 – Atherosclerosis of autologous vein coronary artery bypass graft(s) with other forms of angina pectoris
What it is
This code identifies narrowing or blockage from atherosclerosis in an autologous vein coronary bypass graft, with angina that is not classified as unstable or due to a recent infarction. Use it when the graft itself is the documented disease site.
Clinical signs
Patients typically have symptoms of myocardial ischemia such as chest discomfort, pressure, or exertional angina. Clinical features vary; refer to documentation and confirm that the provider links the angina to the bypass graft disease.
When to use this code
Use I25.718 when the record states atherosclerosis of an autologous vein coronary artery bypass graft and specifies other forms of angina pectoris. This applies to patients with prior CABG using vein grafts, when the graft is the affected vessel. If the note only mentions coronary disease or angina without graft involvement, check documentation.
Do not use for
Do not use this code for native coronary artery disease without graft involvement, or for unstable angina unless the documentation supports a different code. Do not assign it if the bypass graft type is not autologous vein or if the angina diagnosis is unspecified.
Coding tip
Verify both the graft type and the angina type in the provider note before coding.
