Accidental malfunction of shotgun, initial encounter

This code signifies an injury resulting from the unintended discharge or mechanical failure of a shotgun. It specifically indicates that the patient is receiving active treatment for the initial injury caused by this accidental malfunction.

Apply this code when documenting the initial treatment for a patient who has sustained an injury due to a shotgun misfiring, jamming, or otherwise discharging unexpectedly without intentional action. This includes scenarios where a firearm component failure leads to an accidental shot.

• Always assign an external cause code (W33.11XA) in conjunction with an injury code (e.g., S41.001A for open wound of shoulder).
• Ensure the "A" seventh character is used for the initial encounter of care for the injury.
• Distinguish carefully from intentional discharge (e.g., assault, self-harm) or accidental discharge due to user error (e.g., dropping the weapon).
