ICD-10 Code I25.71 – Atherosclerosis of autologous vein coronary artery bypass graft(s) with angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.71 – Atherosclerosis of autologous vein coronary artery bypass graft(s) with angina pectoris
What it is
This code identifies atherosclerotic narrowing or blockage in an autologous vein coronary bypass graft, with angina pectoris present. It applies when the graft itself is the documented site of coronary artery disease.
Clinical signs
Typical documentation includes coronary bypass graft disease plus angina, such as chest discomfort or ischemic symptoms. Clinical features vary; refer to documentation for the graft type and whether angina is stable, unstable, or unspecified.
When to use this code
Use this code when the provider documents atherosclerosis affecting an autologous vein coronary artery bypass graft and also documents angina pectoris. It is appropriate for follow-up visits, admissions, or problem lists when the graft lesion is the active diagnosis. Check documentation if the record does not clearly identify the graft as autologous vein.
Do not use for
Do not use this code for native coronary artery disease without graft involvement. Also avoid it when angina is not documented or when the bypass conduit is not an autologous vein; check documentation.
Coding tip
Confirm both elements in the note: autologous vein graft disease and angina pectoris, before assigning I25.71.
