I am in need of some answers. I have a client that has a provider who has other providers either see his patients or scribes for him. Either way documentation is not clear in the progress notes for coding. I have asked the client to have the provider make an addendum to the notes in question and for whatever reason they will not do this. The client feels that the progress note should be coded the way it stands and my office was told that this clinic works as a team and under one tax ID. I need to know if another doctor (under the same group and Tax ID) can sign for the performing physician and if so, is it necessary to put “on behalf of” or something similar. Also where would i find this information. The client wants regulations in black and white. PLEASE HELP !!
