Person outsd hv veh inj in clsn w statnry obj nontraf, subs

This code describes an injury 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 non-moving object. The incident occurred in a non-traffic setting, such as a private lot or maintenance yard, and this particular code indicates a subsequent encounter for the injury.

Apply this code for follow-up care, such as wound checks, physical therapy, or medication adjustments, for injuries initially sustained when a person was riding on the outside of a heavy transport vehicle that struck a stationary object in a non-roadway environment. Examples include a worker on the side of a train car hitting a platform, or an individual on the exterior of a bus colliding with a building in a depot.

• Ensure the accident occurred in a non-traffic area; otherwise, a different external cause code is needed.
• Verify the patient was on the outside of the vehicle, not inside or a pedestrian.
• Confirm this is a subsequent encounter for the injury, not the initial treatment.
