Source: Data include all treat-and-release discharges from hospital-affiliated emergency departments during 2008 in Arizona, Florida, Georgia, Massachusetts, Missouri, New York, and Wisconsin. Statistics are not reported whenever there are fewer than 10 observations in a particular cell.


Disease categories are based on the Clinical Classification Software, a diagnosis and procedure categorization scheme based on the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM). The HCUP SEDD do not differentiate between the principal diagnosis codes and other diagnosis codes. Therefore, we used all diagnosis codes reported for each visit when creating broader CCS disease categories.
