Contus/lac cereb, w LOC >24 hr w/o ret consc w surv, subs

This code signifies a traumatic brain injury involving both bruising (contusion) and tearing (laceration) of the cerebrum, where the patient experienced a loss of consciousness exceeding 24 hours and has not returned to their baseline neurological status. The patient is still alive at the time of this subsequent encounter, indicating ongoing care for the sequelae of the initial injury.

This code is appropriate for follow-up encounters when a patient is receiving continued treatment or monitoring for a severe cerebral contusion and laceration that resulted in prolonged unconsciousness and persistent neurological deficits. Documentation must clearly state the nature of the cerebral injury, the duration of unconsciousness, the failure to return to pre-existing conscious level, and that this is not the initial treatment encounter.

• Ensure documentation specifies "subsequent encounter" and not an initial or sequela encounter.
• Verify the duration of loss of consciousness is explicitly stated as greater than 24 hours.
• Confirm that the patient has not returned to their pre-existing conscious level, indicating ongoing impairment.
