What 31296 covers

An otolaryngologist typically performs this procedure by guiding an endoscope through the nose to the frontal sinus opening and dilating the ostium, often with a balloon catheter. It may be performed in an office or an operating room for a patient with frontal sinus drainage problems. The service is specific to the frontal sinus; dilation of a maxillary or sphenoid sinus is represented by a different site-specific code.

Report 31296 when the documented work is dilation of the frontal sinus ostium. The operative note should identify the treated sinus and side, describe the endoscopic dilation, and support the clinical need. It has a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, endoscopy family pricing applies. For bilateral treatment, modifier 50 is paid at 150%. An assistant at surgery may be paid; 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.

31296 billing questions

How is 31296 different from 31295 or 31297?

31296 is for dilation of the frontal sinus ostium. Codes 31295 and 31297 describe dilation at the maxillary and sphenoid sinuses, respectively.

When is modifier 50 appropriate?

Use modifier 50 when the frontal sinus dilation is performed bilaterally. CMS identifies bilateral payment at 150%.

Can 31296 be reported with another sinus endoscopy code?

Related endoscopies performed together are subject to endoscopy family pricing. The operative documentation should establish the distinct work and sinus sites treated.

Does the code include same-day postoperative care?

Yes. The 0-day global period includes same-day preoperative and postoperative care.

Can an assistant or co-surgeon be reported?

An assistant at surgery may be paid for this procedure. Co-surgeons and team surgery are not permitted.

What should the operative note identify?

Document the frontal sinus side treated, the endoscopic dilation performed, and the clinical reason for opening the ostium. Distinguish dilation from procedures involving tissue removal.

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.
