Sinus surgery

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.

31201 billing questions

How does this differ from code 31200?

This code represents total intranasal ethmoidectomy. Code 31200 is for anterior ethmoidectomy, so the documented extent of removal determines which code fits.

How does this differ from code 31255?

Code 31255 describes total ethmoidectomy performed endoscopically. This code is for the intranasal approach.

Can modifier 50 be reported for bilateral surgery?

Yes. CMS lists this as a bilateral procedure; when reported with modifier 50, it is paid at 150%.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and related postoperative care through 90 days after surgery.

Can an assistant or co-surgeon be paid?

CMS lists a statutory restriction on assistant-at-surgery payment. Co-surgeons and team surgery are not permitted.

What documentation supports reporting total ethmoidectomy?

The operative report should establish the intranasal approach and total rather than anterior-only ethmoid removal, and identify the side or sides treated.
