This code signifies a severe traumatic injury to the intracranial segment of the left internal carotid artery, resulting in prolonged loss of consciousness exceeding 24 hours. The patient has not regained their baseline conscious level and has survived the initial event. This indicates a significant neurological insult with lasting impact.

This code is appropriate for patients presenting with a documented traumatic intracranial injury to the left internal carotid artery, where the loss of consciousness was observed for more than 24 hours and the patient's neurological status remains below their pre-injury baseline. Documentation must clearly state the laterality, intracranial portion, and the duration and outcome of the loss of consciousness.

• Ensure documentation specifies "left" internal carotid artery and "intracranial portion."
• Verify the duration of loss of consciousness is explicitly stated as "greater than 24 hours" and that the patient has not returned to pre-existing conscious level.
• Confirm this is the "initial encounter" for treatment of this specific injury. Subsequent encounters will require a different seventh character.
