Accidental malfunction of shotgun, subsequent encounter

This code describes an injury or adverse effect resulting from a shotgun that unexpectedly discharged or failed to operate as intended, occurring during a follow-up visit for the initial injury. This includes situations where the firearm discharged without the trigger being pulled, or misfired in a way that caused harm.

Apply this code for subsequent encounters when a patient is being treated for complications, follow-up care, or sequelae directly related to an accidental shotgun malfunction. This would include situations like wound care, physical therapy for an injury sustained, or management of infection stemming from the initial incident.

• Always pair this external cause code with an injury code from Chapter 19 of ICD-10-CM.
• Ensure the encounter is clearly documented as a subsequent visit for the initial injury.
• Distinguish from intentional discharge or assault; this code is strictly for accidental malfunction.
