Appendix A

Up until October 2015, the Michigan Birth Defects registry used the 9th revision to the International Classification of Diseases (ICD-9-CM) to code diagnosis. After October 2015, the registry used ICD-10-CM to code diagnosis.  Diagnostic Code Groupings used for congenital anomaly codes were established by the Centers for Disease Control.
