Adopt a systematic approach to define each step that your surgeon does. Below is a listing of codes for the operative note examples. Codes for operative note 1: “While this tumor had both intradural and extradural components that required a dural incision as well as ethmoidectomy for removal of the intradural and extradural components reqpectively, only a single most definitive approach code may be reported. Since intradural as well as extradural work was performed, the best choice to report the approach was CPT® 61583,” Przybylski says. Codes for operative note 2: This operative note describes an orbitocranial procedure. You report code 61586 (Bicoronal, transzygomatic and/or Lefort 1 osteotomy approach to anterior cranial fossa with or without internal fixation, without bone graft) for the approach component. The portions of this approach include: You may also submit code 61601 for the intradural removal. “Similar to the previous case, the tumor excised has both intradural and extradural components,” Przybylski says. The definitive approach code chose should therefore be the intradural form. It should be noted in both cases that the dural repair is considered part of the definitive procedure. The secondary repair codes 61618 and 61619 are reported for a subsequent repair for post-operative CSF leak after the index procedure.
