Sinus surgery
About 31205: Intranasal anterior ethmoidectomy
Reports surgical removal of anterior ethmoid cells through an intranasal approach for disease requiring ethmoid surgery, rather than an extranasal or endoscopic procedure.
This procedure removes diseased anterior ethmoid air cells through the nasal cavity using a nonendoscopic intranasal approach. Otolaryngologists typically perform it in an operating room for ethmoid sinus disease requiring surgical treatment. The operative report should make clear that the approach was intranasal and identify the anterior ethmoid work performed; endoscopic ethmoidectomy and extranasal ethmoidectomy are distinct approaches with separate codes.
Report the code when the documented operation matches this approach and extent, not based on the diagnosis alone. It has a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. For bilateral reporting with modifier 50, CMS pays at 150%. Assistant-at-surgery payment may be available; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.

31205 billing questions
How does this differ from endoscopic ethmoidectomy?
This code is for an intranasal, nonendoscopic anterior ethmoid procedure. Endoscopic ethmoidectomy codes apply when the surgeon performs the work using a nasal endoscope.
How do I distinguish it from codes 31200 and 31201?
Those codes describe extranasal ethmoidectomy. Use this code for the intranasal anterior approach documented in the operative report.
What documentation supports reporting this code?
The operative report should identify the intranasal approach and the anterior ethmoid removal performed. A diagnosis of ethmoid sinus disease alone does not establish the procedure.
How is bilateral surgery reported?
Report modifier 50 for bilateral performance. CMS pays the bilateral procedure at 150%.
What global and multiple-procedure rules apply?
The code has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and other procedures are subject to a 50% reduction.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is 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 indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
