This webpage provides information about the specific injury codes used in the data on our web-based query system, EpiCenter.

Overview of ICD 9 and 10 codes

These are the standard definitions the Safe and Active Communities (SAC) Branch uses in creating data tables from hospital discharge and death certificate data. All years of hospital discharge data are coded using ICD-9. Starting in 1999, death certificates were coded using ICD-10 cause codes.

• Additional information on ICD-10 (death data) coding can be found at:

Office of Health Information and Research (California Department of Public Health)

• Additional information on ICD-9 (Emergency Department and Hospital Discharge Data) coding can be found at:

Office of Statewide Health Planning and Development (California)

SAC Branch Cause of Injury Definition Codes

The SAC Branch developed these groups by making modest changes to CDC's recommended cause groupings for ICD-9 and ICD-10. See CDC's webpages on ICD-9 and ICD-10 codes for additional information on CDC's cause definitions. 

Special Definitions used in Selected Injury Topics

These are definitions and criteria used in the Selected Injury Topics section of EpiCenter that are used independently of the detailed cause of injury codes. (For example, "Motor Vehicle Traffic-Drivers Only" is a subset of a single category.)
