Both doctors will be using 99221, 99222 or 99223? Or would the consulting dr use 99231, 99232 or 99233? How can more than one doctor use the admission codes (99221-99223)?
no ... one physician will bill for the admission with an initial code plus the AI modifier, the consultant will bill for the initial visit they have with the patient with no modifier. It is just that they will be using the same codes. We must think of these codes as initial inpatient visit codes and the AI modifier will indicate this as an admission visit.
Thank you, Rebecca. We had a lively debate in our office over who was actually the "attending" physician and when to use AI. Your link was especially helpful. Let's just say it made me a "gracious" winner. ;-)
CMS has modifier AI and the AMA CPT 2011 professional edition has A1 as the modifier for Principal Physicain of Record. Which modifier is correct?![]()
