Unsp larger firearm discharge, undetermined intent, init

This code signifies an injury resulting from the discharge of an unspecified larger firearm, where the circumstances surrounding the event (e.g., accidental, self-inflicted, assault) cannot be determined. This diagnosis is used when the specific type of larger firearm is unknown, and the intent of the discharge is unclear.

Apply this code for initial encounters with patients presenting with injuries from a larger firearm when the medical record lacks documentation specifying the firearm type (e.g., rifle, shotgun) and the intent of the discharge is not yet established or remains ambiguous. This is appropriate in emergency department settings or initial evaluations where details are still being gathered.

• Only use for the initial encounter for treatment of the injury.
• Ensure documentation explicitly states "unspecified larger firearm" and "undetermined intent" or similar phrasing.
• Avoid using if a more specific firearm type (e.g., rifle, shotgun) or intent (e.g., accidental, assault) is documented.
