Records with injuries are identified by ICD-9-CM diagnosis code using a scheme recommended by the following 2003 report by the State and Territorial Injury Prevention Directors Association (STIPDA).
Injury Surveillance Workgroup. Consensus Recommendations for Using Hospital Discharge Data for Injury Surveillance. Marietta (GA): State and Territorial Injury Prevention Directors Association; 2003 (available online at http://www.safestates.org/associations/5805/files/HospitalDischargeData.pdf). Please note that in 2010, the organizational name "STIPDA" was changed to the "Safe States Alliance."
Two HCUP variables indicate injuries are reported on the record: INJURY is used to indicate at least one injury is reported in the first-listed or later diagnoses; MULTINJURY is used to indicate that more than one injury is reported, regardless of diagnosis position. The table below lists the diagnosis codes in the range 800-999 used to identify injuries:
