V21.3: Motorcycle rider injured in collision with pedal cycle : person injured while boarding or alighting

The condition described by this specific ICD-10 code, V21.3, refers to injuries sustained by a motorcycle rider during a collision with a pedal cycle, specifically, while they were either stepping onto (boarding) or off (alighting) of the motorcycle. This kind of accident can result in wide-ranging injuries, depending on several factors like the speed of either vehicle, the protective gear the rider was wearing, and how they fell. Common injury sites are the limbs, head, and torso, which could harbor bruises, fractures, lacerations, or even more serious conditions such as concussions and internal injuries. Since the injuries can vary greatly, so can the symptoms, which might range from mild discomfort and visible abrasions to severe pain, impairment, disorientation, or other signs of serious trauma. The progression of these conditions depends heavily on the immediacy and appropriateness of the medical response.
