Other larger firearm discharge, undetermined intent, sequela

This code signifies a long-term complication or late effect resulting from an injury caused by a larger firearm (e.g., rifle, shotgun), where the intent of the discharge (accidental, self-harm, assault) could not be determined. It indicates that the initial injury has resolved, but the patient is now presenting with a residual condition directly attributable to that past event.

Apply this code when documenting a sequela, such as chronic pain, nerve damage, scar contracture, or psychological trauma, that is a direct consequence of a previously sustained larger firearm injury of undetermined intent. This code is used for encounters where the sequela is being treated, not for the initial injury itself.

• Always sequence this code after the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past larger firearm injury of undetermined intent.
• Do not use this code for initial injury encounters; it is exclusively for late effects.
