What 31254 covers

An otolaryngologist uses a nasal endoscope and surgical instruments to remove part of the ethmoid air cells, typically the anterior portion, to treat disease such as chronic inflammation or obstructed drainage. The procedure is commonly performed in a hospital outpatient department or ambulatory surgery center. The extent is partial: complete ethmoid cell removal belongs to a different code. The operative report should identify the treated side, the ethmoid work performed, and the extent of tissue or partitions removed.

Report this code when the surgeon performs partial endoscopic ethmoidectomy, not for diagnostic nasal inspection alone. When related nasal or sinus endoscopies are performed together, CMS endoscopy-family pricing applies. For bilateral surgery, modifier 50 is paid at 150%. The 0-day global period includes same-day preoperative and postoperative care. Medicare does not pay an assistant at surgery for this service; 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.

31254 billing questions

How does this differ from 31255?

31254 describes partial ethmoidectomy, generally involving the anterior ethmoid cells. Use 31255 when the surgeon performs total ethmoidectomy.

Can this be reported with maxillary or frontal sinus surgery?

A surgeon may perform separately indicated work in other sinuses during the same operation. CMS endoscopy-family pricing applies when related endoscopies are performed together.

How is bilateral surgery reported?

Report bilateral surgery with modifier 50; CMS pays the bilateral procedure at 150%.

What documentation supports the partial ethmoidectomy?

The operative report should describe the endoscopic ethmoid work, identify the side, and make clear that the removal was partial rather than total.

Can an assistant surgeon or co-surgeon be billed?

Medicare does not pay an assistant at surgery for this code. 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.
