This code signifies a long-term complication or condition resulting from an injury sustained by an individual who was getting on or off a three-wheeled motor vehicle (e.g., a motorized tricycle, auto rickshaw) during a collision with another non-motorized vehicle (e.g., bicycle, animal-drawn vehicle, pedestrian). The injury itself occurred in the past, and the patient is now presenting with a residual effect of that original trauma.

Use this code when documenting a patient encounter for a sequela (e.g., chronic pain, scar contracture, nerve damage, limited range of motion) directly attributable to an old injury that occurred while boarding or alighting a three-wheeled motor vehicle involved in a crash with a non-motorized vehicle. This code is appropriate for follow-up care related to the lasting effects of such an accident.

• Always assign a sequela code (ending in "S") as a secondary diagnosis, following the code for the specific sequela condition.
• Ensure the medical record clearly links the current sequela to the original injury event described by this external cause code.
• Verify that the collision involved a three-wheeled motor vehicle and a non-motorized vehicle, and that the patient was in the act of boarding or alighting.
