Traum subrac hem w LOC >24 hr w/o ret consc w surv, init

This code signifies a subarachnoid hemorrhage resulting from trauma, where the patient experienced a loss of consciousness lasting more than 24 hours. Crucially, the patient has not returned to their baseline conscious level, and they survived the initial event. This indicates a severe and persistent neurological impact from the traumatic injury.

Apply this code when documentation clearly states a traumatic subarachnoid hemorrhage and specifies a loss of consciousness exceeding 24 hours with no return to the patient's pre-injury conscious state. This code is appropriate for the initial treatment encounter for such a severe injury. Supporting documentation would include neurological assessments, Glasgow Coma Scale (GCS) scores, and physician notes detailing the duration and severity of altered consciousness.

• Ensure documentation explicitly states "traumatic" subarachnoid hemorrhage to differentiate from non-traumatic causes.
• Verify the duration of loss of consciousness is greater than 24 hours and that the patient has not returned to their pre-existing conscious level.
• This code is for the "initial encounter" for treatment of the injury; subsequent encounters would use a different seventh character.
