Question: Virginia Subscriber Answer: Although many ob-gyns describe a sacrospinous colpopexy as "bilateral," you should only report 57282 (Colpopexy, vaginal; extra-peritoneal approach [sacrospinous, iliococcygeus]) once. This code does not take a bilateral modifier and includes fixation to both sides. Code +57267 (Insertion of mesh or other prosthesis for repair of pelvic floor defect, each site [anterior, posterior compartment], vaginal approach [List separately in addition to code for primary procedure]) is an add-on code. You can report it once for the mesh in the anterior vaginal wall and once for the posterior wall. Because this is an add-on code, you should not append a modifier. Keep in mind, however, payers will look for medical necessity for the mesh. How: Therefore, the correct order for the procedures this surgeon performed based on RVUs would be: • 57260 • 57288-51 • 57282-51 • +57267 x 2 (assuming your physician documents the need).
