Notes:
Frequencies include all children reported with a birth defect who were born in Michigan and whose mother was a resident of Branch-Hillsdale-St. Joseph Health Department,
Michigan at the time of birth. This enables the calculation of birth defects prevalence rates. Prior to October 2015, diagnoses were coded using the 9th revision to the International Classification of Diseases - ICD–9–CM.  (See Birth Defect Groups and ICD–9–CM Diagnosis Codes for the codes used to categorize birth defects.) After October 2015, the Birth Defect registry coded diagnoses using ICD–10–CM. (See Birth Defect Groups and ICD–10–CM Diagnosis Codes for the codes used to categorize birth defects.) Diagnostic Code Groupings used in analysis of birth defects are defined by the Centers for Disease Control.
Conditions are reportable if identified within the first two years of a child's life. The frequencies at one year and at two years serve to indicate the time from the birth of the child to the diagnosis of the condition. Birth defect statistics sometimes reflect trends related to data reporting or new testing. See Data Quality Considerations for further details.
