Unsp larger firearm discharge, undetermined intent, subs

This code signifies a follow-up encounter for an injury caused by an unspecified larger firearm, where the intent (e.g., accidental, assault, self-harm) cannot be determined from the medical record. It indicates that the patient is receiving ongoing care for a wound or other sequelae resulting from such an incident.

Use this code for subsequent visits when a patient is being treated for complications, follow-up care, or rehabilitation related to a larger firearm injury. The initial encounter code would have been used for the acute injury, and this code applies when the intent remains unknown and the firearm type is not specified beyond "larger."

• Ensure the documentation clearly states this is a subsequent encounter for the injury.
• Only use when the intent of the firearm discharge is explicitly documented as "undetermined" or cannot be ascertained.
• Avoid if a more specific firearm type (e.g., rifle, shotgun) or intent (e.g., accidental, assault) is documented.
