About 31086: Frontal sinus removal surgery
Frontal sinus removal surgery is reported when an operative procedure removes frontal sinus tissue rather than merely exploring or irrigating the sinus.
Code 31086 represents an operative removal procedure involving the frontal sinus, the air cavity above the eyes that drains into the nasal passages. It is distinct from a procedure limited to examining or opening the sinus. Otolaryngologists and surgeons who manage complex frontal sinus disease may perform this work in an operating room for conditions such as persistent inflammatory disease, a mucocele, or a lesion requiring surgical removal. The operative report should identify the frontal sinus as the treated site and describe the tissue removed and the operative extent.
Report 31086 when the documented operation matches this frontal sinus removal variant, not solely because the diagnosis involves frontal sinus disease. Record the approach, anatomic extent, and concurrent procedures; use the applicable sibling code when the operative details fit another variant. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. In a session with multiple procedures, the highest-valued procedure is paid in full and other procedures at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeons and team surgery are not permitted.

31086 billing questions
How is 31086 different from a frontal sinus exploration code?
31086 represents a removal procedure. Codes 31070 and 31075 describe frontal sinus exploration; use an exploration code when the documented work is limited to exploration rather than the removal procedure represented by 31086.
What should the operative report document?
Document the frontal sinus as the operative site, the approach and extent of the procedure, and the tissue removed. Those details help distinguish 31086 from exploration and from other frontal sinus removal variants.
How does modifier 50 affect payment?
CMS identifies this as a bilateral procedure: reporting modifier 50 results in payment at 150%.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant surgeon or co-surgeon be reported?
Assistant-at-surgery payment may be made. CMS does not permit co-surgeons or team surgery for this code.
How is 31086 affected when other procedures are performed in the same session?
Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50%.
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.
