V81.4: Person injured while boarding or alighting from railway train or railway vehicle

The ICD-10 code V81.4 identifies a specific circumstance in which an individual sustains injuries as a result of boarding or alighting from a railway train or similar vehicle. This situation does not pertain to a biological illness or condition but instead refers to a physical incident involving possible trauma. Injuries in this context can vary greatly in severity, from minor sprains, cuts or bruises, to more serious conditions such as broken bones, concussions or more severe neurological damage. The exact nature of the injury would depend on several factors including the speed of the vehicle, the conditions of the environment, and the health and physical condition of the individual. The affected systems in the body would also vary, depending on the specific nature of the injury. Commonly affected areas could include the musculoskeletal system, the nervous system, or the skin. It's also important to note that psychological trauma could also occur, especially in severe incidents.
