Person on outside of sp off-rd mv injured in traf, subs

This code describes an individual who was a passenger or was otherwise positioned on the exterior of a specialized off-road vehicle, such as an ATV or dirt bike, and sustained injuries in a traffic accident. The "subsequent encounter" designation indicates that this code is used for follow-up care related to the initial injury, not the initial presentation.

Use this code when documenting ongoing treatment, rehabilitation, or follow-up visits for a patient whose injuries resulted from being on the outside of an off-road motor vehicle during a traffic accident. This applies to scenarios like physical therapy for a fracture sustained in such an event, or a follow-up with a specialist for a concussion.

• Ensure the patient was physically on the exterior (e.g., riding on the back, standing on a running board) of the off-road vehicle, not inside.
• Verify that the encounter is for follow-up care, not the initial treatment of the injury.
• Always code the specific injury(ies) sustained in addition to this external cause code.
