Contus/lac cereb, w LOC >24 hr w/o ret consc w surv, sequela

This code signifies a severe traumatic brain injury involving contusion and laceration of the cerebrum, resulting in a prolonged coma (loss of consciousness exceeding 24 hours). The patient has not regained their baseline neurological status and has survived the initial injury, indicating a persistent neurological deficit.

This code is appropriate for patients who have sustained a cerebral contusion and laceration from trauma, experienced an extended period of unconsciousness (over 24 hours), and demonstrate ongoing neurological impairment upon discharge or follow-up. Documentation must clearly state the duration of unconsciousness and the patient's current neurological status relative to their pre-injury state.

• This "S" seventh character indicates a sequela, meaning it's used for complications or conditions arising as a direct result of the initial injury.
• Ensure documentation explicitly states "loss of consciousness greater than 24 hours" and "without return to pre-existing conscious level."
• Do not use this code for initial encounters or subsequent encounters where the patient has fully recovered or the duration of unconsciousness is less than 24 hours.
