Notes:

1 Congenital infections list in "Congenital Code Groupings" table. These infections are based on ICD-9-CM/ICD-10-CM groupings. For details, see table: Congenital Infection Code Groupings.

2ICD-9-CM was used to classify cases reported before October 2015. There were no specific ICD-9-CM codes for congenital herpes simplex virus (HSV) or congenital toxoplasmosis infection. In ICD-9-CM, these infections, and other rare congenital infections, are categorized under "771.2 Other congenital infections"; and cannot be differentiated. After October 2015, this data was collected using ICD-10-CM codes. Numbers in 2015 for these infections represent partial data.

Birth prevalence rate = occurrences per 10,000 live births.

Birth defect statistics sometimes reflect trends related to data reporting or new testing. See Data Quality Considerations for further details.
