What 31295 covers

An otolaryngologist uses a nasal endoscope to guide a balloon into the natural opening of a maxillary sinus and enlarge that drainage pathway. This approach may be used for obstructed maxillary sinus drainage, including in patients with chronic or recurrent sinusitis. The procedure is distinct from creating a wider opening by removing tissue or bone during conventional endoscopic sinus surgery.

Report the code for the maxillary sinus ostium dilation performed, and document the treated side, the sinus, the technique, and the clinical findings supporting the intervention. CMS treats the service as a minor procedure with a 0-day global period, so same-day preoperative and postoperative care is included. For bilateral treatment, modifier 50 is paid at 150%. When related endoscopies are performed together, endoscopy family pricing applies. CMS allows payment for an assistant at surgery; 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.

31295 billing questions

How does this differ from 31256?

31295 describes balloon dilation of the maxillary sinus opening. Code 31256 is used for a conventional endoscopic maxillary sinus exploration and opening rather than balloon dilation.

When would 31267 be a better fit?

Use 31267 when the maxillary sinus procedure includes removal of tissue. Balloon dilation of the ostium without that tissue removal is the distinguishing service for 31295.

How is bilateral treatment reported?

CMS identifies this as a bilateral procedure: report modifier 50 for bilateral treatment. CMS pays the bilateral service at 150%.

What happens when another sinus endoscopy is performed during the same session?

CMS endoscopy family pricing applies when related endoscopies are performed together. The operative report should identify each sinus procedure performed.

Is same-day postoperative care separately included in the global period?

No. The 0-day global period includes same-day preoperative and postoperative care.

Can an assistant surgeon be reported?

CMS may pay for an assistant at surgery. Co-surgeons and team surgery are not permitted for this service.

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.
