Pasngr in hv veh injured in clsn w 2/3-whl mv in traf, subs

This code describes an injury sustained by a passenger in a large transport vehicle (e.g., bus, truck) during a traffic accident involving a motorcycle, scooter, or moped. The "subsequent encounter" indicates that the patient is receiving follow-up care for an injury that occurred previously.

This code is appropriate for documenting ongoing treatment, such as wound care, physical therapy, or follow-up appointments for fractures or internal injuries, resulting from the described collision. It should be used after the initial acute treatment phase.

• Ensure the patient was a passenger, not the driver, of the heavy transport vehicle.
• Verify the collision involved a two- or three-wheeled motor vehicle.
• Confirm this is not the initial visit for the injury; use the appropriate initial encounter code for the first presentation.
