ICD-10 Code I25.722 – Atherosclerosis of autologous artery coronary artery bypass graft(s) with refractory angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.722 – Atherosclerosis of autologous artery coronary artery bypass graft(s) with refractory angina pectoris
What it is
This code identifies atherosclerotic narrowing or blockage in a patient’s own vein or artery graft used for coronary bypass, with angina that remains difficult to control. Use it when the graft disease and refractory chest pain are both documented.
Clinical signs
Typical findings include recurrent or persistent angina after coronary bypass surgery, often despite standard therapy. Clinical features vary; refer to documentation for graft type, ischemic symptoms, and whether angina is described as refractory.
When to use this code
Use this code when the record clearly states atherosclerosis affecting an autologous coronary bypass graft and the patient has refractory angina pectoris. It is appropriate for postoperative follow-up, cardiology notes, or admissions documenting ongoing ischemic chest pain tied to graft disease.
Check documentation if the graft type is not specified or if angina is present without the term refractory. Do not assume this code for native coronary artery disease alone.
Do not use for
Do not use this code for angina without documented graft atherosclerosis, or for disease in non-autologous bypass grafts. Check documentation if the condition involves the native coronary arteries instead.
Coding tip
Code only when both elements are explicit: autologous bypass graft atherosclerosis and refractory angina.
