We have a group of hospitalists (NPs) who perform medical evaluations (H&P) at an inpatient psychiatric facility. We are billing E/M codes 99221-99223 for the H&Ps and the psychiatrists are billing their psych codes. Our diagnoses are primarily medical. However, in a lot of cases the patient has no chronic illnesses therefore we have to use a mental health diagnosis. Both services are done on the same day. Is it appropriate for the hospitalists to bill 99221-99223? Or would it be more appropriate to bill a consult code? Please advise. If you can direct me to more information, that would be appreciated.
