Looking for help from someone familiar with Radiology 1500 claim form billing. My radiologists read all of the outreach x-rays from a lot of rural hospitals and for the local clinics and hospitals from their location in the hospital in our town. There is some confusion as to how box 24B should be filled out. Some think that since our radiologists are located in the hospital all claims should be billed as 22 Out PT even if they are ER, INPT or Clinic visits. My thoughts are that box 24B should be marked depending on the status of the patient which could vary from 11, 21, 22 or 23 and that box 32 is what should take care of billing for the location where the radiologists read the x-rays. Any help welcomed.
