Consultation
       A diagnostic radiology consultation is the service rendered when:
      a. radiographs or ultrasounds made at one institution or facility are referred to a radiologist at a
          different institution or facility for his/her written opinion. In this case, the specific elements are
          as for diagnostic radiology professional component (see page D1);
      b. a radiologist is required to make a special visit at evening or night (17:00h to 07:00h) or on a
         Saturday, Sunday or holiday to consult on the advisability of performing a diagnostic
         radiological procedure which eventually is not done. In this case, the specific elements are
         the same as for consultations; or
      c. when a radiologist is required to render an opinion prior to an interventional procedure and
