Person outsd hv veh inj in clsn w rail trn/veh in traf, init

This code describes an injury sustained by an individual who was positioned on the exterior of a large transport vehicle (e.g., a truck, bus) when it collided with a train or railway vehicle. The incident must have occurred within a traffic accident context, not during a controlled railway operation. The "A" suffix indicates this is the initial encounter for treatment of the injury.

Use this code when documenting injuries to a person who was riding on the outside of a heavy transport vehicle (e.g., clinging to the side, riding on the bumper) that was involved in a collision with a train. This applies to scenarios such as a truck crossing train tracks and being struck, or a bus colliding with a train at a crossing. It specifically excludes individuals inside the heavy transport vehicle or the train.

• Ensure the patient was outside the heavy transport vehicle, not an occupant.
• Verify the collision involved a railway train or vehicle, not another type of vehicle.
• Confirm this is the initial encounter for the injury; subsequent encounters will require different seventh characters.
