This code signifies a traumatic injury to the intracranial segment of the left internal carotid artery, resulting in immediate loss of consciousness of any duration. The patient unfortunately succumbed to the brain injury before regaining consciousness. This indicates a severe, rapidly fatal intracranial vascular trauma.

Apply this code when documentation clearly states a traumatic injury to the left intracranial internal carotid artery, with the patient experiencing loss of consciousness and subsequent death directly attributable to the brain injury prior to awakening. This is an initial encounter code, used for the period of active treatment for the injury.

• Ensure documentation explicitly specifies the left internal carotid artery and its intracranial portion.
• Confirm the patient's death was due to the brain injury and occurred before regaining consciousness.
• Always sequence this code after the primary traumatic brain injury code, if applicable.
