Passenger on bus injured in clsn w 2/3-whl mv nontraf, init

This code signifies an injury sustained by a passenger traveling on a bus when that bus collides with a motorcycle, moped, or similar two- or three-wheeled motor vehicle. Importantly, this collision occurs in a non-traffic environment, such as a parking lot, private driveway, or off-road area. The "A" suffix indicates that this is the initial encounter for the patient's injury.

This code is appropriate when documenting the initial treatment for a bus passenger injured in an incident like a bus backing into a parked motorcycle in a bus depot, or a bus striking a moped on a private campus road. It should be used for the first time a healthcare provider sees the patient for this specific injury.

• Verify the accident occurred in a non-traffic area; otherwise, a different external cause code is needed.
• Confirm the patient was a passenger on the bus, not the driver or a pedestrian.
• Ensure the collision involved a two- or three-wheeled motor vehicle, not a car or truck.
