About the Y24 Code Range
The ICD-10 code Y24 identifies injuries caused by firearm discharges where the intent is undetermined, covering airguns, other firearms, and unspecified types. These codes are used when available information does not clarify whether the firearm injury was accidental, self-inflicted, or inflicted by another person.
This section includes specific codes for airgun discharges (Y24.0), other firearm discharges (Y24.8), and unspecified firearm discharges (Y24.9) all with undetermined intent. Each of these category codes further breaks down by encounter type: initial, subsequent, or sequela (complications or conditions resulting from prior injury). For example, Y24.8XXA pertains to an initial encounter for injury caused by "injury of unknown intent by firearms and explosives," assisting coders when the cause is unclear. The unspecified firearm codes (Y24.9) have extensive synonyms that include various gunshot wound locations, supporting medical coders in matching common injury descriptions—such as "gunshot wound of right thigh"—to the correct ICD-10 code. Overall, the Y24 codes streamline documentation of firearm-related injuries when the motivation or intent cannot be determined.
