Handgun discharge, undetermined intent, subsequent encounter

This code signifies an injury resulting from a handgun discharge where the intent (e.g., accidental, self-harm, assault) cannot be determined by the healthcare provider. It is used for follow-up care, such as wound checks, physical therapy, or medication management, after the initial treatment of the injury.

Apply this code for any subsequent encounters related to a handgun injury where the circumstances surrounding the discharge remain unclear. This includes situations where the patient presents for ongoing care after being discharged from acute treatment, or for complications arising from the initial injury.

• Ensure documentation clearly states "undetermined intent" for the handgun discharge.
• Confirm this is not the initial encounter for the injury; look for "subsequent encounter" documentation.
• Always code the specific nature of the injury (e.g., gunshot wound to the abdomen) in addition to this external cause code.
