Unsp larger firearm discharge, undetermined intent, sequela

This code describes a long-term complication or late effect resulting from an injury caused by an unspecified larger firearm. The original intent of the firearm discharge (e.g., accidental, assault, self-harm) could not be determined at the time of the initial injury. The sequela could be any persistent physical or psychological issue directly attributable to the past firearm incident.

Use this code when documenting a patient presenting with a current health condition that is a direct consequence of a previous injury from an unknown type of larger firearm, where the intent of the discharge was never established. This applies to follow-up encounters for chronic pain, neurological deficits, psychological trauma, or other lasting effects stemming from such an event.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past larger firearm injury of undetermined intent.
• Avoid using this code for initial injury encounters; it is strictly for sequelae.
