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

This code signifies a traumatic subarachnoid hemorrhage where the patient experienced a loss of consciousness exceeding 24 hours and has not yet returned to their baseline neurological status. The patient is still alive and under active treatment for the sequelae of the injury.

Apply this code for follow-up encounters when a patient is still recovering from a traumatic subarachnoid hemorrhage with prolonged loss of consciousness and persistent neurological deficits. Documentation should clearly indicate the original injury mechanism, the duration of unconsciousness, and the ongoing impact on the patient's conscious level.

• Ensure documentation specifies "subsequent encounter" for ongoing care related to the initial injury.
• Distinguish from codes for initial encounters or sequelae (late effects) once active treatment has concluded.
• Verify the duration of unconsciousness (greater than 24 hours) and the lack of return to pre-existing conscious level.
