Accidental malfunction from oth firearms, subs encntr

This code indicates an injury or adverse health effect resulting from the unintended discharge or operation of a firearm other than a handgun, rifle, or shotgun. It specifically applies to follow-up care for such an incident, after the initial treatment has been rendered.

Use this code for subsequent encounters when a patient presents for ongoing management of an injury sustained due to an accidental malfunction of a specified firearm (e.g., antique firearm, flare gun, or other non-standard firearm). This includes follow-up appointments for wound care, physical therapy, or monitoring of complications related to the original injury.

• Always sequence this external cause code after the primary diagnosis code describing the actual injury.
• Ensure the documentation clearly specifies the firearm type as "other specified" and that the encounter is not the initial treatment.
• Verify that the incident was an accidental malfunction, not an intentional discharge or assault.
