Machine gun discharge, undetermined intent, subs encntr

This code indicates an injury sustained from a machine gun discharge where the intent (e.g., accidental, assault, self-harm) cannot be determined. It is used for encounters following the initial treatment of the injury.

Apply this code for follow-up visits, rehabilitation, or subsequent care related to a machine gun wound when the circumstances surrounding the discharge remain unclear. This includes situations where the patient is seen for complications, wound care, or physical therapy after the initial acute phase.

• Always assign an external cause code (Y90-Y99) to provide additional context for the injury.
• Ensure documentation clearly states the undetermined intent and that this is not the initial encounter for the injury.
• Do not use this code if the intent of the machine gun discharge is known or if it is the first time the patient is being seen for this injury.
