Unsp rider of mtrcy injured in clsn 2/3whl in traf, init

This code signifies an injury sustained by an unspecified rider of a motorcycle (not a driver or passenger) involved in a traffic accident with another two- or three-wheeled motor vehicle. The "unspecified" nature means the specific role (e.g., driver, passenger) of the injured individual on their motorcycle is not documented.

This code is appropriate when documentation clearly indicates a motorcycle rider was injured in a collision with another motorcycle, moped, or scooter on a public roadway, and their specific role on their own motorcycle is not specified. It is used for the initial encounter for treatment of these injuries.

• Ensure the documentation explicitly states a "rider" and not a "driver" or "passenger" if the specific role is unknown.
• Verify the collision involved two- or three-wheeled motor vehicles exclusively.
• Confirm this is the initial treatment for the injury; subsequent encounters will require different seventh characters.
