Laryngology procedure
About 31536: Operative laryngeal biopsy with scope
An otolaryngologist uses an operating scope during direct laryngoscopy to biopsy a laryngeal lesion, such as a suspicious vocal fold abnormality.
An otolaryngologist uses a direct laryngoscope with an operating telescope or microscope to inspect the larynx and take tissue from a lesion for examination. Common indications include a suspicious vocal fold or laryngeal mucosal abnormality, such as a persistent lesion requiring histologic diagnosis. The procedure is commonly performed in an operating room, often under general anesthesia; the specimen is sent for pathology review.
Report this code when the operative scope is used and tissue is sampled for biopsy, rather than when the primary service is diagnostic visualization alone or definitive lesion excision. The operative note should identify the laryngeal site, lesion, biopsy performed, and use of the scope. CMS assigns a 0-day global period, including same-day preoperative and postoperative care. Related endoscopies performed together are subject to endoscopy-family pricing. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.

31536 billing questions
When should this code be chosen instead of 31535?
Choose this code when the laryngeal biopsy is performed with an operating telescope or microscope. Code 31535 describes the related biopsy service without that scope distinction.
Does taking a biopsy include definitive removal of the lesion?
A biopsy samples tissue for diagnosis. When the operative service is excision of a laryngeal tumor or lesion rather than biopsy, consider the applicable excision code, such as 31541 when an operating scope is used.
Can modifier 50 be reported for biopsies on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code; do not use modifier 50.
What should the operative note document?
Document the laryngeal site and lesion, the tissue sampling, and use of the operating telescope or microscope. The record should make clear that the service was a biopsy rather than diagnostic inspection alone or definitive excision.
How does CMS handle other endoscopies performed in the same session?
When related endoscopies are performed together, CMS applies endoscopy-family pricing. Payment is not determined as though each related endoscopy were an independent 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 indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
