What 31287 covers
An otolaryngologist typically performs this procedure through the nasal passages, using an endoscope to open the sphenoid sinus. It may be performed for sphenoid sinus disease when the surgeon needs to establish or improve drainage but does not remove tissue from the sinus. The operative report should identify the sphenoid sinus treated and describe the surgical opening; tissue removal from that sinus points to a different code.
Report the service for the sphenoidotomy itself, not as a substitute for a more extensive procedure that includes ethmoid surgery or sphenoid tissue removal. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, endoscopy-family pricing applies. For bilateral work, modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

31287 billing questions
When should 31287 be chosen over 31288?
Use 31287 when the sphenoid sinus is surgically opened without tissue removal from that sinus. When tissue is removed from the sphenoid sinus, consider 31288 instead.
How does 31287 differ from 31257?
31287 covers sphenoidotomy alone. 31257 includes total ethmoid surgery along with sphenoidotomy.
Can modifier 50 be reported for bilateral sphenoidotomy?
Yes. CMS identifies this as a bilateral procedure; modifier 50 is paid at 150%.
Is same-day postoperative care included?
Yes. The code has a 0-day global period, which includes same-day preoperative and postoperative care.
Can an assistant or co-surgeon be billed?
Assistant-at-surgery payment is allowed only with documentation of medical necessity. Co-surgeons and team surgery are not permitted.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
