Prsn brd/alit hv veh injured in collision w 2/3-whl mv, subs

This code describes an injury sustained by an individual who was in the process of getting on or off a large transport vehicle (e.g., bus, train, streetcar) when it collided with a motorcycle, scooter, or moped. The "subsequent encounter" indicates that this code is used for follow-up care after the initial treatment for the injury.

This code is appropriate for documenting ongoing care, such as wound checks, physical therapy, or medication management, for a patient whose initial injury occurred during the specified type of collision. It would be used for visits after the initial emergency room or acute care admission.

• Ensure the documentation clearly states the patient was boarding or alighting a heavy transport vehicle.
• Verify the collision involved a two- or three-wheeled motor vehicle, not another type of vehicle.
• Confirm this is a follow-up visit for an injury previously treated; do not use for the initial encounter.
