Driver of hv veh injured in collision w oth mv in traf, subs

This code signifies a follow-up visit for a driver of a large commercial vehicle (e.g., truck, bus) who sustained injuries from a multi-vehicle collision on a public roadway. It indicates that the initial treatment for the accident has already occurred, and the patient is now presenting for ongoing care related to those injuries.

Apply this code for subsequent encounters such as physical therapy, follow-up appointments with specialists, wound care, or medication management for injuries sustained in the described traffic accident. This code is appropriate when the patient is no longer in the acute phase of injury but is still receiving active treatment.

• Ensure the encounter is indeed "subsequent" and not the initial treatment for the injury.
• Always code the specific injury(ies) sustained in the accident first, followed by this external cause code.
• Verify the patient was the driver of a "heavy transport vehicle" and the collision involved "other motor vehicles."
