Accidental malfunction of gas, air or sprng-op gun, init

This code describes an injury resulting from the unintended discharge or operation of a gas, air, or spring-powered firearm, excluding BB guns, pellet guns, and paintball guns. This malfunction is accidental, meaning it was not intentionally caused by the user or another party.

Apply this code when a patient presents with an injury sustained due to an unexpected firing or mechanical failure of an air rifle, air pistol, or other similar non-powder firearm. This includes scenarios where the gun discharges without the trigger being pulled, or due to a mechanical defect.

• Ensure the documentation clearly states the injury was due to an accidental malfunction of the gun, not intentional discharge.
• Verify the type of gun involved is a gas, air, or spring-operated firearm, and not a BB gun, pellet gun, or paintball gun (which have their own specific codes).
• Confirm this is the initial encounter for the injury.
