V86.6: Passenger of all-terrain or other off-road motor vehicle injured in nontraffic accident

The condition is defined as an injury sustained by a passenger as a result of a nontraffic accident involving an all-terrain or other off-road motor vehicle. Nontraffic accidents refer to those that take place anywhere other than on a public highway. This could include accidents on private roads, parking lots, driveways, or any other nonpublic area. Such injuries can occur during recreational or work activities where these vehicles are in use. This condition is not disease-based but occurs as a result of unexpected and unplanned events. The type and severity of injuries can vary widely, from minor cuts and bruises to more serious traumas such as fractures, concussions, or internal injuries. The affected systems in the body will depend on the nature of the accident and the type of injury incurred.
