Pasngr in hv veh inj in clsn w 2/3-whl mv in traf, sequela

This code signifies a long-term consequence or complication arising from an injury sustained by a passenger in a large vehicle (e.g., bus, truck) involved in a traffic accident with a motorcycle or moped. It indicates that the initial injury has resulted in a chronic condition, disability, or other lasting effect requiring ongoing medical attention.

Apply this code when documenting a sequela, such as chronic pain, paralysis, or a permanent disability, directly attributable to an injury sustained as a passenger in a heavy transport vehicle that collided with a two- or three-wheeled motor vehicle. This code is appropriate for follow-up encounters occurring long after the initial injury and its acute treatment.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, fracture nonunion).
• Ensure documentation clearly links the current condition to the original traffic accident and specifies the patient's role as a passenger in a heavy transport vehicle.
• Verify that the accident involved a two- or three-wheeled motor vehicle, as other vehicle types would necessitate a different external cause code.
