Prsn brd/alit a car injured in clsn w rail trn/veh, subs

This code describes an injury sustained by an individual who was in the process of getting into or out of a car when that car was involved in a collision with a train or other railway vehicle. The "D" seventh character indicates this is a subsequent encounter, meaning the patient is receiving follow-up care for an injury initially treated in a previous encounter.

This code is appropriate for documenting ongoing treatment, such as wound care, fracture management, or physical therapy, for injuries sustained in such a railway-car collision. It should be used after the initial acute phase of treatment has concluded and the patient is returning for further care related to the original incident.

• Ensure the documentation clearly specifies the patient was boarding or alighting a car, not merely an occupant.
• Verify that the encounter is for follow-up care of an injury from the initial collision, not for a new injury or the initial treatment.
• Confirm the collision involved a railway train or vehicle, as opposed to another type of vehicle.
