This code describes a sequela of an intracranial injury to the right internal carotid artery, not otherwise specified, that resulted in a prolonged loss of consciousness exceeding 24 hours. The patient survived the initial injury but did not return to their baseline conscious level, indicating persistent neurological deficits.

This code is used for follow-up encounters when a patient presents with long-term neurological complications stemming from a past intracranial right internal carotid artery injury. Documentation should clearly indicate a history of the specified injury, a loss of consciousness greater than 24 hours, and a persistent altered conscious state or other sequelae directly attributable to the initial trauma.

• Requires a seventh character "S" for sequela, indicating a late effect of the injury.
• Ensure documentation specifies "right" internal carotid artery and "intracranial portion."
• Do not use for acute injury; this code is for residual conditions after the acute phase has passed.
