ICD-10 Code I25.732 – Atherosclerosis of nonautologous biological coronary artery bypass graft(s) with refractory angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.732 – Atherosclerosis of nonautologous biological coronary artery bypass graft(s) with refractory angina pectoris
What it is
This code identifies hardening and narrowing of a nonautologous biological coronary bypass graft, along with refractory angina pectoris. It means the graft is affected by atherosclerotic disease and chest pain persists despite usual management.
Clinical signs
Clinical features vary; refer to documentation. You may see ongoing angina symptoms, evidence of ischemia, or documentation that the graft is a nonautologous biological coronary bypass graft with refractory angina.
When to use this code
Use this code when the provider documents atherosclerosis in a nonautologous biological coronary artery bypass graft and specifically states refractory angina pectoris. It is appropriate when the graft disease is the focus of the encounter and the angina is described as persistent or difficult to control. Check documentation if the graft type or angina status is unclear.
Do not use for
Do not use this code for angina without documented graft atherosclerosis, or for atherosclerosis in a different coronary vessel. If the bypass graft type is not nonautologous biological, check documentation.
Coding tip
Verify both elements in the record: the graft type and the refractory angina diagnosis.
