Unsp rider of mtrcy injured in clsn oth non-mv nontraf, subs

This code describes an injury sustained by an unspecified rider of a motorcycle (not a passenger or driver) during a collision with a non-motorized vehicle (e.g., bicycle, animal-drawn vehicle, pedestrian) in an area not open to public traffic. This specific code is for a subsequent encounter, meaning the patient is receiving follow-up care for the initial injury.

Apply this code when documenting ongoing treatment, such as cast changes, wound care, or physical therapy, for a motorcycle rider injured in a non-traffic collision with a non-motor vehicle. This is appropriate for any encounter after the initial visit for the injury.

• Ensure the documentation clearly specifies the patient was an "unspecified rider" and not a driver or passenger.
• Verify the collision involved a "non-motor vehicle" and occurred in a "nontraffic accident" setting.
• Always pair with an injury code (e.g., fracture, sprain) and other relevant external cause codes to provide a complete picture.
