Car passenger injured in collision w hv veh nontraf, subs

This code signifies a car passenger's injury sustained in a collision with a large commercial vehicle (like a truck or bus) that occurred off a public roadway, such as in a parking lot or private drive. The "subsequent encounter" indicates that this code is used for follow-up care after the initial treatment for the injury.

Apply this code for any subsequent visits related to injuries (e.g., fracture care, physical therapy, wound checks) resulting from a car-heavy transport vehicle collision that did not happen on a public road. This includes scenarios like a passenger injured when their car was struck by a bus in a private parking garage or by a delivery truck on a private estate.

• Ensure the accident definitively occurred in a non-traffic setting.
• Confirm the patient was a passenger, not the driver, of the car.
• Verify this is for follow-up care, not the initial treatment encounter.
