Contus/lac cereb, w LOC of unsp duration, sequela

This code signifies a chronic or late effect of a cerebral contusion or laceration, where the initial injury involved an unquantified period of unconsciousness. It indicates that the patient is experiencing ongoing symptoms or complications directly attributable to this past brain trauma.

Apply this code when documenting a patient presenting with residual neurological deficits, cognitive impairments, or other long-term sequelae stemming from a previously sustained cerebral contusion or laceration with unrecorded loss of consciousness. Documentation must clearly link the current condition to the prior brain injury.

• Always sequence this sequela code after the code(s) for the specific residual condition(s) being treated (e.g., cognitive deficit, epilepsy).
• Ensure documentation explicitly states the current condition is a "sequela of" or "due to prior" the specified cerebral injury.
• Avoid using this code for acute injuries; it is strictly for late effects.
