Our facility has opened an OP Courtesy room for specialist to perform follow-up consultations. We (the facility) provide them with a Medical Assistant. We have begin to bill CPT 99201 and 99202 for the facility portion. The physician's are concerned that they cannot bill for the same service and now the question is "how do they bil"? Can anyone shed some light? Is there a modifier or is it just enough that they bill on a 1500 for professional and we bill on a UB04 for the facility?
