Can I use these codes (depending on the carrier) with place of service 23? My Surgeon is often called to the ER to make a decision for surgery. Ie. abdominal pain, decision for surgery. While the patient is not technicially admitted, I'm confused if this is a consult as that is what he is doing or ER visit...??? patient later admitted for Op. Sometimes by my surgery doc, sometimes admitted by attending...confussed
