V86: Occupant of special all-terrain or other motor vehicle designed primarily for off-road use, injured in transport accident

V86.4: Person injured while boarding or alighting from all-terrain or other off-road motor vehicle

The condition outlined in ICD-10 code V86.4 refers to an injury sustained by a person while they are either getting on or getting off an all-terrain or other off-road motor vehicle. These types of accidents usually happen due to the unpredictable nature of off-road terrains and the potential instability of the vehicle during the boarding or alighting process. The severity and nature of the injuries can vary widely, ranging from minor cuts, bruises, or sprains to more serious cases such as fractures, spinal injuries, head trauma, or internal organ damage. The affected system depends on the particular type of injury incurred. Symptoms can be instant or develop over time, and often include pain, bruising, swelling, and difficulty with mobility in the affected area. It is essential to understand that the term "Person injured while boarding or alighting from all-terrain or other off-road motor vehicle" is not a medical diagnosis, but a situation leading to potential injuries.
