About coding generalized arteriosclerosis
The ICD-10-CM code for generalized arteriosclerosis is I70.91 (Generalized atherosclerosis).
Within I70.9 (other and unspecified atherosclerosis), I70.91 is specifically for generalized atherosclerosis. Related codes cover unspecified atherosclerosis (I70.90) and chronic total occlusion of artery of the extremities (I70.92).
Use an additional code to identify: 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 tobacco use (Z72.0).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
