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

This code signifies a severe intracranial injury, not otherwise specified, that resulted in a prolonged coma exceeding 24 hours. The patient's neurological status did not recover to their baseline level of consciousness, and they survived the initial injury, now presenting with lasting neurological deficits.

Apply this code for patients who have sustained a severe head injury with documented loss of consciousness for over 24 hours, and whose current neurological assessment confirms persistent impairment in their level of consciousness compared to their pre-injury state. This code is used for the sequelae, indicating the long-term effects of the injury.

• Requires clear documentation of the duration of unconsciousness and the patient's pre-injury neurological baseline.
• Always sequence this sequela code after the acute injury code, if applicable, or as a primary diagnosis for follow-up care.
• Differentiate from codes indicating full return to consciousness or those with shorter durations of unconsciousness.
