Traum hemor cereb, w LOC >24 hr w/o ret consc w surv, subs

This code signifies a traumatic bleeding within the cerebrum where the patient experienced a loss of consciousness exceeding 24 hours and has not returned to their baseline cognitive state. This indicates a severe and persistent neurological deficit resulting from the initial head injury.

This code is appropriate for follow-up encounters when a patient is still recovering from a traumatic cerebral hemorrhage with prolonged loss of consciousness and ongoing neurological impairment. Documentation should clearly state the duration of unconsciousness, the patient's current conscious level relative to their pre-injury state, and that the patient survived the initial event.

• Ensure documentation explicitly states "subsequent encounter" to justify the 7th character 'D'.
• Distinguish from codes for initial encounters or those where consciousness has returned to pre-existing levels.
• Always code the underlying traumatic brain injury (TBI) first, followed by any associated neurological deficits.
