Person injured in collision betw car and hv veh, subs

This code signifies a patient presenting for follow-up care, rehabilitation, or management of complications stemming from injuries sustained in a traffic accident. Specifically, the accident involved a car and a heavy transport vehicle (e.g., a semi-truck, bus, or large commercial truck). The "subsequent encounter" indicates that this is not the initial visit for the injury.

Use this code for any encounter after the initial treatment of injuries resulting from a car-heavy transport vehicle collision. This includes visits for physical therapy, wound care, medication adjustments, or evaluation of ongoing symptoms related to the original trauma. It is appropriate for patients returning for scheduled follow-ups or unexpected complications.

• Always pair this external cause code with an injury code (e.g., fracture, sprain, concussion) to fully describe the patient's condition.
• Ensure documentation clearly states the patient is being seen for a follow-up or subsequent care related to the original accident.
• Verify the type of vehicles involved in the collision to confirm it was a car and a heavy transport vehicle.
