How to code Atelectasis

J98.11 is atelectasis and J98.19 is other pulmonary collapse. Atelectasis of a newborn is coded to P28.0 (primary) or P28.1- (other and unspecified).

Minor atelectasis seen on imaging is only coded when the provider documents it as clinically significant. Postoperative atelectasis is not a complication by default. Report J95.89 only when the provider says it is a complication of the procedure. Pneumothorax is coded to J93.-, not J98.1-.
