Inj r int carotid, intcr w LOC >24 hr w ret consc lev, init

This code signifies a traumatic injury to the intracranial segment of the right internal carotid artery, not specified elsewhere, resulting in a prolonged loss of consciousness exceeding 24 hours. The patient subsequently recovered to their baseline conscious state. This represents the initial phase of treatment for this severe cerebrovascular injury.

Apply this code for patients presenting with a documented traumatic intracranial right internal carotid artery injury where the initial period of unconsciousness lasted longer than 24 hours, followed by a return to their pre-injury neurological status. Supporting documentation must clearly specify the laterality, intracranial location, and the duration and resolution of the loss of consciousness.

• Ensure documentation explicitly states "initial encounter" for the injury. Subsequent encounters would require a different seventh character.
• Verify the duration of loss of consciousness; codes exist for shorter durations or if consciousness does not return to baseline.
• Confirm the injury is to the intracranial portion of the right internal carotid artery and not an extracranial segment.
