Several NC DETECT animal bite-related reports were developed based on chief complaint and triage note keyword searches and ICD-9-CM codes. Using the Animal Bite Keyword Report, statewide ED visit data were extracted for 2008Á2010. ED visit records in NC DETECT were examined manually to assess the performance of case definition keywords. Using the Animal Bite ICD-9-CM Code Report, statewide ED visit data were extracted for 2008Á2010. The following ICD-9-CM injury codes are included in this report: E906.0 (dog bite), E906.1 (rat bite), E906.3 (bite of other animal except arthropod) and E906.5 (bite by unspecified animal). The burden of ICD-9-CMÁcoded animal bite visits to total ED visits was examined by age group and gender.
