Traum subrac hem w LOC >24 hr w ret consc lev, init

This code signifies a traumatic subarachnoid hemorrhage where the patient experienced a loss of consciousness lasting longer than 24 hours. Crucially, the patient's conscious level subsequently returned to their pre-injury baseline. This represents the initial phase of treatment for this specific injury.

This code is appropriate for the initial encounter of a patient presenting with a traumatic subarachnoid hemorrhage and documented loss of consciousness exceeding 24 hours, followed by a full recovery of their pre-injury conscious state. Documentation should clearly specify the cause as traumatic, the duration of unconsciousness, and the return to baseline neurological status.

• 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's consciousness returned to their pre-existing level.
• This "A" seventh character indicates an initial encounter; subsequent care would require different seventh characters (e.g., D for subsequent, S for sequela).
