I am having a disagreement regarding billing NP's. I'm hoping someone can assist me. We are a Pediatric office. We are having a flu clinic on Saturday along with our urgent care/sick visits. There are two NP's on the schedule. I was always told that an MD had to be in the office with the NP's. They don't have to go in the room with them but MD has to sign off services. One of the NP's told me that was not neccessary, that she could work without a supervising MD here. We do not bill under our NP's, we bill under the supervising physician. I would appreciate any/all input on this asap. If I am in fact correct, I need proof. I'm checking the Federal Register also. Thanks so much!
