This code signifies a long-term consequence or complication arising from an injury sustained by an individual who was positioned on the exterior of a large transport vehicle (e.g., bus, truck) during a collision with a two- or three-wheeled motor vehicle (e.g., motorcycle, scooter). The original incident occurred in a non-traffic setting, meaning it did not happen on a public roadway. The "sequela" indicates that the current encounter is for the management of a condition that is a direct result of that past injury.

This code is appropriate for follow-up encounters where a patient is being treated for chronic pain, disability, scarring, or other lasting health issues directly attributable to the specified non-traffic accident. It should be used when the acute phase of the original injury has passed, and the current treatment addresses the residual effects. Examples include physical therapy for persistent mobility limitations or surgical intervention for delayed complications.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., chronic pain, malunion fracture).
• Ensure documentation clearly links the current condition to the original injury event described by this external cause code.
• Verify that the original accident occurred in a "nontraffic" setting, as defined by ICD-10-CM guidelines, and involved the specific vehicle types.
