Nasal and sinus surgery
About 31254: Endoscopic partial ethmoidectomy
Reports endoscopic removal of part of the anterior ethmoid air cells during surgery for ethmoid sinus disease, rather than complete ethmoidectomy.
An otolaryngologist uses a nasal endoscope and surgical instruments to remove part of the ethmoid air cells, typically the anterior portion, to treat disease such as chronic inflammation or obstructed drainage. The procedure is commonly performed in a hospital outpatient department or ambulatory surgery center. The extent is partial: complete ethmoid cell removal belongs to a different code. The operative report should identify the treated side, the ethmoid work performed, and the extent of tissue or partitions removed.
Report this code when the surgeon performs partial endoscopic ethmoidectomy, not for diagnostic nasal inspection alone. When related nasal or sinus endoscopies are performed together, CMS endoscopy-family pricing applies. For bilateral surgery, modifier 50 is paid at 150%. The 0-day global period includes same-day preoperative and postoperative care. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.
