Prsn brd/alit pk-up/van injured in collision w hv veh, subs

This code describes an injury sustained by an individual who was in the process of entering or exiting a pick-up truck or van when it was involved in a collision with a large commercial vehicle, such as a semi-truck or passenger bus. The "subsequent encounter" designation indicates that this code is used for follow-up care after the initial treatment of the injury.

Use this code for any follow-up visits, rehabilitation, or ongoing management of injuries sustained in the described motor vehicle accident. This includes scenarios like physical therapy for a fracture, wound care for lacerations, or monitoring for post-concussion syndrome, provided the patient was boarding or alighting a pick-up/van during the collision with a heavy transport vehicle.

• Ensure the patient was specifically boarding or alighting, not fully inside or outside, the pick-up truck or van.
• Verify the other vehicle involved was a heavy transport vehicle or bus, not another passenger car or motorcycle.
• Always pair this external cause code with an injury code (e.g., fracture, sprain, concussion) and the appropriate place of occurrence and activity codes.
