What 31267 covers
An otolaryngologist or rhinologist performs this endoscopic operation to access the maxillary sinus, enlarge its opening, and remove tissue from inside the sinus. Typical clinical situations include chronic maxillary sinus disease with polyps or other obstructive tissue. The operative report should establish that tissue was removed from the maxillary sinus, not merely from the nasal cavity or the sinus opening. The service is performed in an office or facility setting, depending on the case and where the surgery takes place.
Report the code when the operative work includes both maxillary sinus access and tissue removal from that sinus; an opening without tissue removal is a different service. Document the side, endoscopic work, tissue removed, and any other sinus procedures performed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. For bilateral surgery, modifier 50 is paid at 150%. When related endoscopies are performed together, endoscopy family pricing applies. CMS does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.

31267 billing questions
How does this differ from 31256?
Use 31267 when tissue is removed from within the maxillary sinus as part of the endoscopic work. 31256 represents maxillary sinus access without that tissue removal.
Does tissue removed from the nasal cavity qualify?
No. The documentation should identify tissue removed from inside the maxillary sinus; removal limited to the nasal cavity or sinus opening does not establish that work.
How is bilateral surgery reported?
CMS identifies this as a bilateral procedure. Report modifier 50 for bilateral surgery; CMS pays it at 150%.
Can another related sinus endoscopy be reported at the same session?
A separate endoscopic procedure may be reported when the operative work supports it at another sinus site. CMS endoscopy family pricing applies when related endoscopies are performed together.
What is the global period?
It has a 0-day global period. Same-day preoperative and postoperative care is included.
Can an assistant or co-surgeon be reported?
CMS does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.
