What 31575 covers

An otolaryngologist commonly passes a flexible scope through the nose to inspect the larynx and assess structures such as the vocal folds and their movement. In an office or facility setting, the examination may help evaluate hoarseness, voice change, throat symptoms, or swallowing complaints. This code represents diagnostic visualization, not an examination that includes biopsy, lesion removal, or injection treatment.

Document the reason for the examination, the scope examination performed, structures and findings observed, and relevant vocal fold movement. The service has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Do not use modifier 50; CMS identifies bilateral adjustment as inappropriate for this service. Assistant-at-surgery payment is restricted, and 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.

31575 billing questions

When should 31575 be used instead of 31576?

Use 31575 for flexible-scope diagnostic visualization without biopsy. When the examination includes a biopsy, 31576 describes the biopsy service.

Can 31575 be reported when a lesion is removed?

When the scope examination includes lesion removal, use the code describing that treatment, such as 31578, rather than reporting a diagnostic-only service for the same examination.

What documentation supports 31575?

Record the indication, flexible-scope examination, structures visualized, findings, and relevant vocal fold movement.

Should modifier 50 be appended for both vocal folds?

No. CMS identifies bilateral adjustment as inappropriate for this service; do not append modifier 50.

How are multiple procedures in the same session paid?

The highest-valued procedure is paid in full, and other procedures performed in the same session are subject to a 50% reduction.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment is restricted for 31575. Co-surgeons and team surgery are not permitted.

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.
