Otolaryngology procedure
About 31576: Flexible laryngoscopy with biopsy
An otolaryngologist uses a flexible scope to inspect the larynx and obtain tissue from a suspicious area for diagnostic evaluation.
This service involves passing a flexible endoscope to examine the larynx and taking one or more tissue samples from an abnormal area. Otolaryngologists commonly perform it in an office or facility when a vocal fold or other laryngeal finding needs tissue diagnosis. The scope provides visualization and access for the biopsy; the purpose is sampling, not removing a lesion as treatment.
Report the service when the flexible examination includes an actual tissue biopsy, and document the sampled site, endoscopic findings, and biopsy performed. Same-day preoperative and postoperative care is included in the 0-day global period. When related endoscopies are performed together, endoscopy family pricing applies. A bilateral adjustment is not appropriate. Medicare does not pay for an assistant at surgery, and co-surgeons and team surgery are not permitted for this service.

31576 billing questions
How does this differ from diagnostic flexible laryngoscopy?
This code includes tissue sampling during the flexible examination. Use diagnostic flexible laryngoscopy when the examination is performed without a biopsy.
When would a laryngoscopy code for lesion removal be more appropriate?
Use the removal service when the lesion is excised or otherwise removed as treatment. This code represents biopsy sampling for diagnosis, not therapeutic lesion removal.
What documentation supports reporting this service?
Document the laryngeal site examined, the abnormal finding, and that tissue was obtained with the flexible scope. The record should distinguish biopsy sampling from inspection alone or lesion removal.
Can modifier 50 be used for biopsies on both sides?
No. The CMS bilateral adjustment does not apply to this service, and modifier 50 is inappropriate.
How does payment work when related endoscopies are performed together?
CMS endoscopy family pricing applies when related endoscopies are performed together. The code also has a 0-day global period, so same-day preoperative and postoperative care is included.
Can an assistant or co-surgeon be reported?
Medicare does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.
