About 31201: Intranasal total ethmoidectomy
Reports total ethmoid air-cell removal through an intranasal approach for extensive ethmoid disease when the surgeon removes more than the anterior cells.
This operation removes the ethmoid air cells through the nasal cavity using an intranasal approach rather than a sinus endoscope. An otolaryngologist typically performs it in an operating room for extensive ethmoid disease, such as chronic ethmoid sinusitis or diffuse polyposis, when total ethmoid removal is required. The code represents total, not anterior-only, ethmoidectomy and is distinct from an external approach or endoscopic ethmoidectomy.
Report the code when the operative documentation supports total ethmoidectomy by the intranasal route. Document the approach, extent, side or sides treated, and indication. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care through day 90. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Bilateral surgery reported with modifier 50 is paid at 150%. Assistant-at-surgery services are not paid; co-surgeons and team surgery are not permitted.
