Person outside hv veh injured in clsn w hv veh nontraf, subs

This code describes an injury sustained by an individual who was positioned on the exterior of a large transport vehicle (e.g., truck, bus) when it collided with another heavy transport vehicle or bus. The collision occurred in a non-traffic setting, such as a private lot or industrial area, and this specific code indicates a subsequent encounter for the injury.

Apply this code for follow-up care related to injuries from a collision where a person was on the outside of a heavy transport vehicle, and that vehicle then struck another heavy transport vehicle or bus in a non-public roadway. Examples include a worker on the side of a delivery truck hit by another truck in a warehouse yard, or a person on the exterior of a bus struck by another bus in a depot.

• Ensure the accident explicitly occurred in a "nontraffic" environment.
• Verify the patient was on the outside of the heavy transport vehicle, not inside.
• Confirm this is a subsequent encounter for the injury, not the initial treatment.
