International Classification of Diseases (ICD) codes, which are documented in hospital discharge data, are often used to identify cases of severe maternal complications. However, little is known regarding the validity of their use in this manner. Therefore, the authors of the present study defined the positive predictive value (PPV) of ICD codes used to identify maternal morbidity at 2 academic centers: Massachusetts General Hospital (MGH) and the University of Michigan Health System (UMHS).
