ICD-10 Code I25.729 – Atherosclerosis of autologous artery coronary artery bypass graft(s) with unspecified angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.729 – Atherosclerosis of autologous artery coronary artery bypass graft(s) with unspecified angina pectoris
What it is
This code identifies coronary artery bypass graft disease in an autologous graft, meaning the patient’s own vessel was used, with associated atherosclerosis and angina that is not further specified. Use it when the graft itself is the documented site of disease.
Clinical signs
Patients may have chest discomfort or other ischemic symptoms related to graft narrowing or blockage. Clinical features vary; refer to documentation, especially if the record confirms angina without a more specific type.
When to use this code
Use this code when the provider documents atherosclerosis affecting an autologous coronary bypass graft and angina pectoris, but does not specify the angina type. It is appropriate for follow-up visits, diagnostic evaluations, or encounters where graft disease is the active documented problem. Check documentation if the graft type or angina detail is unclear.
Do not use for
Do not use this code for native coronary artery atherosclerosis without graft involvement. Do not assign it if the record specifies a different graft type or a more specific angina diagnosis.
Coding tip
Confirm both the graft source and the exact angina wording in the note before assigning I25.729.
