Car passenger injured in collision w hv veh in traf, subs

This code signifies an injury sustained by a car passenger in a traffic accident involving a heavy transport vehicle or bus, where the patient is being seen for follow-up care after the initial treatment. It indicates the specific mechanism of injury and the patient's role in the collision, occurring on a public roadway.

Use this code for subsequent encounters when a car passenger is receiving ongoing treatment, rehabilitation, or follow-up for injuries sustained in a collision with a large commercial vehicle or bus. This applies after the initial acute care has been provided and the patient is no longer in the emergency or immediate post-injury phase.

• Ensure the encounter is for follow-up care, not the initial treatment, as indicated by the "D" seventh character.
• Verify the patient was a passenger in a car and the other vehicle was a heavy transport vehicle or bus.
• Confirm the accident occurred in a traffic setting (e.g., public road, highway).
