When ordering an x-ray, the routing should go to the Diagnostic Imaging (DI) system, not to a laboratory. That means the Lab Company field should be left as None, since labs handle laboratory tests and are not involved in imaging orders. Setting the DI Company to All ensures the order is available at every imaging site or DI unit within the system, increasing the likelihood that the order can be completed promptly if one location is unavailable or busy. In short, only routing to diagnostic imaging and making that route accessible across all imaging facilities best supports timely and successful imaging orders.
