An established psychiatric patient was scheduled for a bariatric surgery psychiatric evaluation. The patient has been treated for 300.4 and 296.32. The NPP dictated a report for the evaluation. Since this is not a new course of treatment but a rendering of an opinion at the request of another agency, this would be billed as a consultation code, correct? What would you use for DX? Does anyone have any guidance on this? Again, it is a psychiatric evaluation performed at the request of a Bariatric Surgery Center. Thank you to anyone who can provide some guidance.
