Which code among the Tom Smith encounter represents coronary artery disease with native arteries?

• A. I21.29
• B. I25.10
• C. I48.91
• D. I25.60

Answer: (B)

Distinguishing disease in native coronary arteries from disease in bypass grafts is the key idea. For native-artery coronary artery disease, the code is I25.10 when there is no angina, and I25.11 if angina is present. This reflects that the atherosclerosis is in the patient’s original vessels, not in a bypass graft. The other codes point to different situations: an acute myocardial infarction (I21.x) is an acute event, not chronic CAD in native arteries; atrial fibrillation (I48.91) is a rhythm disorder; and I25.60 or similar codes describe atherosclerosis of bypass grafts, not native arteries. Therefore, I25.10 is the correct choice for native-artery coronary disease without angina, with I25.11 used if angina is documented.
