This code describes a patient who was a passenger in a heavy transport vehicle (e.g., bus, truck) and sustained injuries in a traffic accident involving a collision with a train or other railway vehicle. The "D" seventh character indicates this is for a subsequent encounter, meaning the patient is receiving follow-up care for injuries sustained in the initial event.

Use this code when documenting ongoing treatment, such as physical therapy, wound care, or follow-up appointments, for injuries sustained by a passenger in a heavy transport vehicle involved in a train collision. This applies after the initial acute care phase.

• Ensure the patient was a passenger, not the driver, of the heavy transport vehicle.
• Verify the encounter is for follow-up care, not the initial treatment, to justify the "D" seventh character.
• Always code the specific injuries sustained in addition to this external cause code.
