ICD-10 Code I25.76 – Atherosclerosis of bypass graft of coronary artery of transplanted heart with angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.76 – Atherosclerosis of bypass graft of coronary artery of transplanted heart with angina pectoris
What it is
This code identifies atherosclerotic narrowing in a bypass graft supplying a transplanted heart, with angina pectoris present. It tells you the graft disease is linked to chest pain from reduced blood flow.
Clinical signs
Typical documentation may include chest pain or pressure consistent with angina, especially with exertion or stress. Angina should be documented by the provider; clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states atherosclerosis of a coronary bypass graft in a transplanted heart and also documents angina pectoris. It is appropriate for encounters focused on graft-related ischemic symptoms or evaluation of known disease.
Code it only when the provider links the atherosclerotic graft disease to the transplanted heart and identifies angina. Check documentation if the note mentions coronary disease, transplant history, or chest pain without that specific relationship.
Do not use for
Do not use this code for angina without documented graft atherosclerosis, or for native coronary artery disease in a non-transplanted heart. Check documentation if the record is unclear.
Coding tip
Verify both the bypass graft location and the transplanted-heart context before assigning I25.76.
