Intcran inj w LOC >24 hr w/o ret consc w surv, subs

This code signifies a type of intracranial injury, not otherwise specified, that has resulted in a prolonged loss of consciousness exceeding 24 hours. Crucially, the patient has not regained their baseline conscious level and has survived the initial injury. This code is used for follow-up care after the initial injury.

This code is appropriate for subsequent encounters when a patient is receiving ongoing treatment or monitoring for an intracranial injury that initially caused a coma lasting over 24 hours, and they remain in a state of altered consciousness. Documentation should clearly state the duration of unconsciousness, the patient's current neurological status relative to their pre-injury state, and confirm that the patient is still alive.

• Ensure documentation explicitly states "loss of consciousness greater than 24 hours" and "without return to pre-existing conscious level."
• This is a subsequent encounter code; do not use it for the initial treatment of the injury.
• Distinguish from codes for intracranial injuries with shorter durations of unconsciousness or those where the patient has fully recovered consciousness.
