Prsn brd/alit hv veh injured in collision w ped/anml, subs

This code signifies an injury sustained by an individual who was in the process of getting on or off a large transport vehicle (e.g., bus, train, large truck) when that vehicle collided with either a pedestrian or an animal. This specific code is for a subsequent encounter, meaning the patient is receiving follow-up care for an injury initially treated in a prior encounter.

Apply this code when a patient presents for ongoing treatment, such as wound care, physical therapy, or follow-up imaging, for an injury sustained during the described boarding/alighting incident. This would include scenarios where a passenger was exiting a bus and was injured when the bus struck a dog, and they are now returning for a cast change.

• Ensure the documentation clearly indicates the patient was boarding or alighting a heavy transport vehicle at the time of the collision.
• Verify that the collision involved either a pedestrian or an animal, not another vehicle or object.
• Confirm this is a subsequent encounter for the injury; use the appropriate initial or sequela encounter code for other visits.
