Query purpose:
This query is intended to identify visits in the emergency department (ED) with diagnostic codes and/or chief complaints associated with a broad range of self-harm injuries and/or behavior. This includes codes (including ICD-10-CM code R45.88 which may or may not co-exist with a self-harm injury code or self-harm text) and text associated with self-harm (e.g., intentional poisoning, intentional self-harm by handgun discharge, nonsuicidal self-harm), regardless of suicidal intention.
