Bus occupant (driver) (passenger) injured in unsp traf, init

This code signifies an injury sustained by an individual who was an occupant (either driver or passenger) of a bus involved in a traffic accident where the specific type of accident is unknown. It indicates the initial phase of care for such an injury.

Apply this code when documentation confirms a bus occupant was injured in a traffic collision, but the details of how the accident occurred (e.g., collision with another vehicle, pedestrian, or object) are not specified. This is appropriate for the first encounter for treatment of the injury.

• Ensure the documentation explicitly states the patient was a bus occupant.
• Only use when the type of traffic accident is truly unspecified; if details are available, a more specific external cause code should be used.
• The "A" seventh character indicates an initial encounter for active treatment.
