Occup of 3-whl mv inj in clsn w rail trn/veh nontraf, subs

This code describes an injury sustained by an individual riding in an unspecified position on a three-wheeled motor vehicle during a collision with a train or railway vehicle. The incident occurred in a non-traffic setting, such as a private crossing or rail yard, and represents a follow-up visit for the injury.

This code is appropriate for documenting subsequent care, such as follow-up appointments, rehabilitation, or further diagnostic testing, for a patient who was an occupant of a three-wheeled vehicle involved in a non-traffic railway collision. It should be used when the specific role of the occupant (e.g., driver, passenger) is not documented.

• Always assign an external cause code (V00-Y99) in conjunction with this code to fully describe the circumstances of the injury.
• Ensure the "D" seventh character is appropriate for a subsequent encounter; "A" for initial encounter or "S" for sequela would be used for different stages of care.
• Verify that the accident occurred in a "nontraffic" setting, as traffic accidents involving railway vehicles have different code categories.
