Unsp intracranial injury w LOC >24 hr w ret consc lev, init

This code signifies a head injury of an unspecified nature that resulted in a prolonged period of unconsciousness, exceeding 24 hours. Crucially, the patient subsequently regained their baseline level of consciousness. This diagnosis indicates the initial presentation and treatment for this specific injury.

Apply this code when documentation clearly states an intracranial injury of unknown type, accompanied by a loss of consciousness lasting more than 24 hours, and the patient has returned to their pre-injury conscious state. This is appropriate for the initial hospital admission or encounter for this injury. Documentation must specify the duration of unconsciousness and the return to baseline.

• Ensure the medical record explicitly states "loss of consciousness greater than 24 hours" and "return to pre-existing conscious level."
• This code is for an "unspecified" intracranial injury; avoid using it if a more specific type of intracranial injury (e.g., contusion, hemorrhage) is documented.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, followed by any associated external cause codes.
