Accidental discharge of other larger firearm, subs encntr

This code signifies an injury resulting from the unintended firing of a large firearm, such as a rifle or shotgun, during a follow-up visit. It indicates that the patient is receiving continued care for complications, healing, or rehabilitation related to the initial accidental discharge.

Apply this code for any encounter after the initial treatment for an injury sustained from an accidental discharge of a large firearm. This includes follow-up appointments for wound care, physical therapy, or management of long-term effects. It would not be used for the initial emergency room visit or acute care.

• Ensure the documentation clearly states the encounter is subsequent to the initial injury.
• Verify the firearm involved was a "larger firearm" (e.g., rifle, shotgun) as opposed to a handgun.
• Always code the specific injury sustained in addition to this external cause code.
