Accidental malfunction from unsp firearms or gun, init

This code signifies an injury resulting from an unintended discharge or failure of an unspecified firearm or gun. It indicates that the patient is presenting for the initial treatment of this specific injury.

This code is appropriate for documenting the first encounter for a patient who has sustained an injury due to an accidental firearm malfunction where the specific type of firearm or gun is not documented. This includes situations where a gun misfires, discharges unexpectedly, or otherwise fails in a way that causes injury, and the firearm's characteristics are unknown.

• Ensure documentation clearly states the injury was due to an accidental malfunction and not an intentional act or assault.
• Only use this code for the initial encounter for treatment of the injury. Subsequent encounters will require a different seventh character.
• If the type of firearm is known (e.g., handgun, rifle), a more specific W34.1- subcategory should be used.
