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

What 31541 covers

An otolaryngologist performs direct operative laryngoscopy to expose and remove a tumor in the larynx, using an operating microscope or telescope for visualization. The service is typically performed in an operating room, often under general anesthesia, for a lesion that requires excision rather than tissue sampling alone. The excised tissue may be sent for pathology; the pathology examination is a separate service when performed by a laboratory.

Select this code when the operative report supports tumor excision during direct laryngoscopy and documents use of the operating microscope or telescope. Excision without that operating scope is reported with 31540; biopsy alone is a different service. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, endoscopy family pricing applies. Modifier 50 is inappropriate for this code. CMS does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.

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.
