Pasngr in hv veh injured in nonclsn trnsp acc in traf, subs

This code signifies an injury sustained by a passenger in a large vehicle (e.g., bus, train, large truck) during a traffic-related incident that did not involve a collision with another vehicle or object. This could include injuries from sudden stops, swerving, or internal events within the vehicle while in motion on a public roadway. The "D" suffix indicates this is a subsequent encounter for care related to the initial injury.

Apply this code for follow-up visits, rehabilitation, or ongoing treatment for injuries sustained by a passenger in a heavy transport vehicle involved in a non-collision traffic accident. Examples include a bus passenger falling due to a sudden stop, or a train passenger injured by an abrupt deceleration, where the incident occurred on a public thoroughfare and no impact with another entity took place.

• Ensure the documentation clearly specifies the patient was a passenger, not the driver.
• Verify the accident was a "noncollision" event and occurred in "traffic" (e.g., on a public road or railway).
• Confirm this is a subsequent encounter for the injury, not the initial treatment.
