Ask Dr. Z

Patient has a coronary/LV angio (93458) and attempted FFR via radial access. FFR is unsuccessful due to spasm, so it wasn't charged. The angio findings are documented with a note that the patient will return at a later date for FFR and possible intervention by another physician. This occurs nine days later. The second dictation gives the findings of the FFR x two vessels and states that no intervention is needed. After querying the physician, he states that a repeat angio was performed, but not dictated, because the findings were documented in the initial report. He added the angiogram in an addendum. Initially I felt that that we would not be able to charge for the second procedure at all because the repeat angio was not indicated and 93571/93572 are add-on codes. With the addendum, would it be appropriate to charge codes 93454-77, 93571, and 93572? Also, what if there was no addendum?
