What 58679 covers
A gynecologic surgeon reports this code for a laparoscopic operation involving a fallopian tube or ovary that does not match a specific listed procedure code. The operative report should identify the anatomy treated, the surgical approach and technique, the work performed, and why a listed code does not describe the procedure. It is not a substitute for a specific code when the operation matches a defined service such as tubal cauterization, tubal occlusion, or removal of an adnexal structure.
Medicare assigns status C: there is no national physician fee schedule payment, and the Medicare Administrative Contractor prices each claim. The contractor also sets the global period. Standard multiple-procedure reduction applies when other procedures are performed in the same session; modifier 50 is used for bilateral procedures. Include documentation that supports the unlisted-code selection and allows the contractor to assess the service.
