The company I work for has about 5 different offices that we bill for. They are all under the same Tax ID. One of our patients was seen by our Family Practioner and then was seen by our Podiatrist a couple weeks later. We billed the Podiatry claim as a new patient since they are seperate specialties and they are not even in the same location. BCBS denied our claim stating it should have been an Established Patient code because the patient had been seen by our company before. Is this correct? I thought since the specialty was different and the doctor was different it wouldn't matter that the doctors were under the same umbrella.
