Person injured wh brd/alit from a 3- or 4- wheeled ATV, subs

This code signifies an injury sustained by an individual during the act of getting on or off a three- or four-wheeled all-terrain vehicle. It specifically applies to follow-up care for such an injury, indicating that the initial treatment has already been rendered. The injury could range from minor sprains to more severe fractures or internal trauma.

This code is appropriate for subsequent encounters related to an injury that occurred while a patient was either mounting or dismounting an ATV. Examples include follow-up appointments for wound care, physical therapy for a fracture sustained during the incident, or medication management for pain resulting from the original injury. It should be used after the initial encounter code for the injury has been reported.

• Ensure the documentation clearly states the injury occurred during boarding or alighting from an ATV, not while operating it.
• Verify that this is a subsequent encounter, meaning the patient is receiving ongoing care for an injury previously treated.
• Always code the specific injury (e.g., fracture, sprain) first, followed by this external cause code.
