One of our surgeons was called into the OR by and OB/GYN for colovesical fistula repair. Our surgeon did not open or close the patient but only provided a two layer closure of the bladder for the fisutla. After he completed that two layer closure the OB/GYN completed the closure of patient. We are thinking the billing should be
44660 with modifier 52 indicating reduced services. Any input would be appreciated.
