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

This code signifies a traumatic subarachnoid hemorrhage where the patient experienced a loss of consciousness lasting longer than 24 hours. Crucially, the patient did not return to their pre-existing level of consciousness and survived the initial event, now presenting with sequelae. This indicates persistent neurological deficits or complications stemming from the initial injury.

Apply this code for patients who have sustained a traumatic subarachnoid hemorrhage with prolonged coma (greater than 24 hours) and exhibit ongoing neurological impairment or a reduced level of consciousness compared to their baseline. Documentation must clearly state the traumatic etiology, duration of unconsciousness, and the presence of sequelae.

• Ensure documentation explicitly differentiates between traumatic and non-traumatic subarachnoid hemorrhage.
• Verify the duration of loss of consciousness and the patient's current neurological status relative to their pre-injury baseline.
• This "S" code indicates a sequela, meaning it should be used for encounters after the acute phase of the injury, when the long-term effects are being addressed.
