About coding coronary artery arteriosclerosis
The ICD-10-CM code for coronary artery arteriosclerosis is I25.10 (Atherosclerotic heart disease of native coronary artery without angina pectoris). The official index lists 58 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on I25.10.
Within I25.1, choose I25.10 (without angina pectoris) only when documentation doesn't support a more specific option: with angina pectoris (I25.11).
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.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
