Dr. did transurethral resection of bladder tumor on pt (52240) Tumor was found to be very large and affected well over 90% of pts bladder. Dr. spent an hour resectioning tumor, and removed several ounces. However, procedure had to be terminated due to visibility becoming impaired. So basically I have an increased procedure and reduced procedure at the same time. Should I bill modifier 22 since he indicated that he spent excessive time on resection? Modifier 52 because even though time was excessive, he was unable to completely remove the tumor? Or should I use no modifier at all?
