ICD-10 Code I25.792 – Atherosclerosis of other coronary artery bypass graft(s) with refractory angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.792 – Atherosclerosis of other coronary artery bypass graft(s) with refractory angina pectoris
What it is
This code identifies atherosclerotic disease in a coronary bypass graft, with angina that persists despite usual management. Use it when the graft is the documented site and the angina is specifically described as refractory.
Clinical signs
Patients typically have ongoing chest pain or ischemic symptoms despite treatment. Clinical features vary; refer to documentation for evidence of graft disease and refractory angina pectoris.
When to use this code
Use this code when the provider documents atherosclerosis affecting a coronary bypass graft other than a specified graft type, and the angina is refractory. It may appear in follow-up, cardiology, or problem-list documentation when persistent angina is linked to graft disease. Check documentation if the graft type or angina status is unclear.
Do not use for
Do not use it for native coronary artery atherosclerosis without bypass graft involvement. Do not use it if the record does not clearly state refractory angina pectoris or if another more specific bypass graft code applies.
Coding tip
Confirm both the graft location and the term “refractory angina” in the provider note before assigning I25.792.
