Contus/lac cereb, w LOC >24 hr w ret consc lev, init

This code signifies a traumatic brain injury involving both bruising (contusion) and tearing (laceration) of the cerebrum, the largest part of the brain, resulting in a prolonged loss of consciousness exceeding 24 hours. Crucially, the patient's conscious state has returned to their baseline level prior to the injury.

Apply this code for initial encounters where documentation confirms a cerebral contusion and laceration, a Glasgow Coma Scale (GCS) score indicating unconsciousness for over 24 hours, and subsequent recovery to the patient's pre-injury conscious state. This is appropriate for the acute phase of care following such an injury.

• Ensure documentation explicitly states "loss of consciousness greater than 24 hours" and "return to pre-existing conscious level."
• Do not use this code if the loss of consciousness duration is unspecified or less than 24 hours.
• Sequence this code first as the primary diagnosis when it is the reason for the encounter.
