Contus/lac cereb, w LOC of 6 hours to 24 hours, sequela

This code describes a sequela of a traumatic brain injury involving both bruising (contusion) and tearing (laceration) of the cerebrum, where the patient experienced a prolonged period of unconsciousness lasting between 6 and 24 hours. "Sequela" indicates that this code is used to report a late effect or complication of the initial injury, after the acute phase has passed.

Use this code when documenting a patient presenting with long-term neurological deficits or complications directly attributable to a past cerebral contusion and laceration. The original injury must have been associated with a loss of consciousness within the 6 to 24-hour timeframe. Documentation should clearly link the current condition to the previous brain trauma and specify the duration of the initial loss of consciousness.

• Always sequence this sequela code after the code for the specific late effect or complication being treated (e.g., cognitive deficits, epilepsy).
• Ensure the medical record explicitly states the duration of the loss of consciousness from the initial injury to justify the "6 hours to 24 hours" specificity.
• Distinguish from acute injury codes (S06.334A, S06.334D) which are used during the initial encounter or subsequent encounters for active treatment of the injury.
