Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 31255 covers

An otolaryngologist uses a nasal endoscope to operate on the ethmoid sinuses, removing the anterior and posterior ethmoid air cells. This procedure may be performed for chronic ethmoid sinus disease, including disease associated with nasal polyps, in a hospital or ambulatory surgical setting. The operative report should identify the side treated and document the extent of ethmoid dissection.

Report this code when the surgeon performs a total ethmoidectomy, rather than a partial ethmoidectomy. If the operation also includes frontal sinus exploration or sphenoid sinus surgery, select the applicable combined endoscopy code when its service is performed. CMS applies endoscopy family pricing when related endoscopies are performed together. For bilateral surgery, modifier 50 is paid at 150%. The 0-day global period includes same-day preoperative and postoperative care. CMS does not pay an assistant at surgery; co-surgeons and team surgery are not permitted.
