We have a patient that we did extensive cranial vault reconstruction and the code for this is 61558. Both surgeons for Plastics and Neurosurgery acted as co-surgeons and the code does not allow for co-surgery.. Does anyone have suggestions how to handle this so both physicians get covered for their services? (was told there is a some kind of special way to bill this, but the person telling me this does not have an answer) Thanks for the help.
