How to code Coronary Artery Disease
Coronary artery disease is coded within category I25 (chronic ischemic heart disease). I25.10 reports atherosclerotic heart disease of native coronary artery without angina pectoris and is the most frequently assigned CAD code.
I25.11x codes are combinations that capture CAD with specific angina types, including unstable angina (I25.110), angina pectoris with documented spasm (I25.111), and other forms of angina (I25.118). Assign the combination code rather than reporting angina separately.
An old (healed) myocardial infarction is reported with I25.2, while a current AMI is coded acutely from category I21. A family history of ischemic heart disease uses Z82.49.
