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

This code describes a sequela (late effect) of an injury sustained by a passenger in a large transport vehicle, such as a bus or train, that was involved in a collision with a motorcycle or moped. The accident occurred in a non-traffic setting, meaning it did not happen on a public roadway. The "S" suffix indicates that this code is for the sequela of the initial injury, not the acute injury itself.

Use this code when documenting a condition or complication that is a direct result of an injury sustained in the described accident, and the initial injury has already healed or reached its maximum medical improvement. This could include chronic pain, scar tissue, nerve damage, or psychological conditions directly attributable to the past event. It is appropriate for follow-up visits where the focus is on the long-term effects of the original trauma.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., chronic pain, scar contracture).
• Ensure the documentation clearly links the current condition to the past accident described by this external cause code.
• Verify that the accident indeed occurred in a non-traffic setting and involved a heavy transport vehicle and a two- or three-wheeled motor vehicle.
