ICD-10 Code I25.719 – Atherosclerosis of autologous vein coronary artery bypass graft(s) with unspecified angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.719 – Atherosclerosis of autologous vein coronary artery bypass graft(s) with unspecified angina pectoris
What it is
This code identifies atherosclerotic narrowing or blockage in an autologous vein coronary bypass graft, along with angina pectoris that is not further specified. Use it when the graft is the documented site of disease and chest pain is attributed to coronary ischemia.
Clinical signs
Typical findings include exertional or rest chest pain, pressure, or discomfort consistent with angina. Clinical features vary; refer to documentation, especially if testing or provider assessment links symptoms to the bypass graft.
When to use this code
Use this code when the record clearly states atherosclerosis of an autologous vein coronary artery bypass graft and angina pectoris, but the angina type is not specified. It may appear in cardiology notes, discharge summaries, or problem lists. Check documentation if the graft type or angina classification is unclear.
Do not use for
Do not use this code for native coronary artery disease without graft involvement, or for angina that is documented as unstable, variant, or other specific types. Check documentation if the bypass conduit is not an autologous vein.
Coding tip
Code the graft site and the documented angina type exactly as written; unspecified angina should not be upgraded to a more specific form.
