This code describes a patient who sustained injuries in a collision between a three-wheeled motor vehicle they were either boarding or alighting from, and a railway train or vehicle. The "D" suffix indicates this is a subsequent encounter for care after the initial treatment of the injury.

Use this code for follow-up visits, such as cast changes, wound care, physical therapy, or medication management, for injuries sustained in the described accident. It is appropriate when the patient is receiving routine care during the healing or recovery phase.

• Ensure the patient was an occupant (boarding or alighting) of a three-wheeled motor vehicle, not a pedestrian or occupant of the train.
• Verify that the encounter is for ongoing care of the injury, not the initial treatment or sequelae.
• Confirm the collision involved a railway train or vehicle, distinguishing it from other types of motor vehicle accidents.
