This code signifies an injury sustained by an individual who was in the process of getting on or off a large transport vehicle (like a truck or bus) and was involved in a collision with another heavy transport vehicle or bus. The "D" seventh character indicates that this is a subsequent encounter, meaning the patient is receiving follow-up care for an injury initially treated elsewhere.

This code is appropriate for documenting follow-up care for injuries such as fractures, sprains, or internal injuries resulting from a collision where the patient was boarding or alighting a heavy transport vehicle. It would be used when the patient presents for rehabilitation, cast changes, wound checks, or other ongoing management related to the initial incident.

• Ensure the documentation clearly states the patient was boarding or alighting a heavy transport vehicle at the time of the collision.
• Verify that the collision involved another heavy transport vehicle or bus, not a car or other type of vehicle.
• The "D" seventh character is crucial for subsequent encounters; use "A" for initial encounters and "S" for sequela.
