Rates Are Per 10,000 Michigan Born Resident
Live Births. Rates include all children reported with a birth
defect who were born in Michigan and whose mother was a resident at
the time of birth. This enables the calculation of birth defects prevalence
rates. Birth defect statistics sometimes reflect trends related to data reporting or new testing. See
Data Quality Considerations for further details.
Unstable Rates:In order to produce a meaningful graph, some single-year, unreliable rates were smoothed using additional years of data. Conditions are reportable if identified within the first two years of a child's life. The prevalence frequencies used to calculate the rates in this table represent cases diagnosed within the first year of life.
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.
