This code signifies a severe, lasting neurological deficit resulting from an intracranial injury to the left internal carotid artery. The patient experienced a prolonged loss of consciousness exceeding 24 hours, and their conscious level has not returned to their baseline state, indicating permanent neurological impairment. This code is used for the sequelae of such an injury.

Apply this code for patients presenting with chronic neurological deficits directly attributable to a past intracranial left internal carotid artery injury. Documentation must clearly state a history of loss of consciousness greater than 24 hours without full recovery, and that the current presentation is a sequela of this specific injury. This code is appropriate when the initial injury has resolved, and the patient is now being treated for the long-term effects.

• This code is for the sequela of the injury, not the acute injury itself.
• Ensure documentation specifies the left internal carotid artery and the intracranial portion.
• Verify the duration of loss of consciousness and the lack of return to pre-existing conscious level are explicitly documented.
