Person outside hv veh inj in clsn w ped/anml in traf, subs

This code describes injuries sustained by an individual who was positioned on the exterior of a large transport vehicle (e.g., bus, train, large truck) when it collided with a pedestrian or an animal. This specific code is used for follow-up care or subsequent encounters related to the initial injury from this type of traffic accident.

Apply this code when documenting ongoing treatment, rehabilitation, or complications for a patient who was injured while riding on the outside of a heavy transport vehicle during a collision with a pedestrian or animal. This would include scenarios such as a patient returning for a cast change, physical therapy, or a follow-up appointment for a concussion sustained in such an event.

• Ensure the encounter is for follow-up care, not the initial treatment, as indicated by the "D" seventh character.
• Confirm the patient was on the outside of a heavy transport vehicle, not inside, and that the collision involved a pedestrian or animal.
• Always code additional external cause codes to fully describe the circumstances of the injury, such as the activity at the time of the incident and the place of occurrence.
