I just starting the billing of an IDTF Sleep Disorder Center-I have probably a very simple question– We have a medical director who interprets the tests (26) and bills for this himself. I do the billing for the facility who does the sleep studies performed by licensed technicians. My question is–who do I use as the "rendering provider" when billing the sleep studies (95811 TC) when they are just performed by technicians? I would imagine this same "medical director" is the interpreting and supervising provider for this facility–so would he be the one I put down as the "rendering" even if he is the one who did not actually perform the tests? Thanks for any help you may have.
