Notes:
Frequencies include all children reported with a birth defect who were born in Michigan and whose mother was a resident of St. Clair County at the time of birth. This enables the calculation of birth defects prevalence rates. Diagnoses are coded using the 9th revision to the International Classification of Diseases - ICD 9 CM.  Diagnostic Code Groupings used for congenital anomaly codes are as used by the Centers for Disease Control. (See Birth Defect Groups and ICD-9-CM Diagnosis Codes for the codes used to categorize birth defects.)
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.
