About I25.11

I25.11 is the ICD-10-CM diagnosis code for Atherosclerotic heart disease of native coronary artery with angina pectoris. It belongs to category I25 (chronic ischemic heart disease), block I20-I25 (ischemic heart diseases) and chapter 9 (diseases of the circulatory system). It is a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.

Within I25.1 (Atherosclerotic heart disease of native coronary artery), I25.11 is specifically for Atherosclerotic heart disease of native coronary artery with angina pectoris. Related codes cover without angina pectoris (I25.10).

To report this condition, pick the subcode that matches the documentation: I25.110 (pectoris), I25.111 (with documented spasm), I25.112 (pectoris), I25.118 (pectoris) and I25.119 (pectoris).

Use an additional code to identify: chronic total occlusion of coronary artery (I25.82), exposure to environmental tobacco smoke (Z77.22), history of tobacco dependence (Z87.891), occupational exposure to environmental tobacco smoke (Z57.31), tobacco dependence (F17.-) and 1 more.
