What 31237 covers

An otolaryngologist typically performs this procedure in an office, ambulatory surgery center, or hospital. Through a nasal endoscope, the physician obtains a biopsy, removes a polyp, or clears material such as crusts, clots, or devitalized tissue. Debridement may be performed during follow-up after endoscopic sinus surgery; the documented service must support actual endoscopic tissue treatment rather than inspection alone.

Select the code based on the work performed, and document the treated site and side, the tissue action, and any specimen sent for pathology. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. For bilateral work, modifier 50 is paid at 150%. When related endoscopies are performed together, endoscopy-family pricing applies. An assistant at surgery is not paid under the statutory restriction; 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.

31237 billing questions

When is this code appropriate instead of diagnostic nasal endoscopy?

Use this code when endoscopy includes a biopsy, polypectomy, or debridement. Inspection and evaluation without one of those therapeutic or tissue-sampling services may support a diagnostic endoscopy code instead.

Can this code describe postoperative sinus debridement?

Yes, when the physician performs endoscopic debridement, such as clearing crusts, clots, or devitalized tissue. Document the treated area and the work performed.

How is bilateral treatment reported?

CMS identifies this as a bilateral procedure. Report modifier 50 for bilateral work; CMS payment is 150%.

What happens when related endoscopies are performed together?

CMS applies endoscopy-family pricing when related endoscopies are performed together. The medical record should identify each procedure and its distinct purpose and site.

Is same-day postoperative care included?

Yes. The 0-day global period includes same-day preoperative and postoperative care. A debridement performed on a later date is not within that same-day global period.

Can an assistant surgeon or co-surgeon be reported?

An assistant at surgery is not paid under the statutory restriction. CMS does not permit co-surgeons or team surgery for this procedure.

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.
