I am new to billing Nutritional Counseling. We have a registered dietician providing the service. Our patient's are referred to her by our endocrinology clinic as well as family practice clinic. I am confident we are billing the correct CPT's (97802 and 97803) we are not doing group at this point. My issue is that some of the insurance carriers are denying because the dietician is not credentialed. When we call we are told the carrier does not credential dieticians. So how are we to bill and get paid for this service when the patient has the benefit? I am at a loss. Is it appropriate to bill as incident to? we are getting an order from the physician just not sure what we are doing wrong. Any assistance would be greatly appreciated.
