Otolaryngology
About 31578: Flexible laryngoscopic lesion removal
Reports flexible endoscopic removal of a laryngeal lesion, such as a vocal fold lesion, when the physician physically removes it through the scope.
An otolaryngologist typically performs this procedure using a flexible laryngoscope to visualize the larynx and remove a lesion through the scope. It may be performed in an office or facility when the lesion can be reached and treated with the flexible endoscopic approach. The service involves removal, not simply inspection or tissue sampling; the operative note should identify the lesion, its laryngeal location, the removal technique, and the result.
Report this code when the physician removes a lesion using flexible laryngoscopy; use a biopsy, laser-treatment, or foreign-body code when that is the service performed instead. Documentation should support the therapeutic work rather than diagnostic visualization alone. 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. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

31578 billing questions
How does this differ from flexible laryngoscopy with biopsy?
Use 31578 when the lesion is removed. Use 31576 when the physician obtains tissue for biopsy rather than removing the lesion as the therapeutic service.
Can diagnostic laryngoscopy be reported separately?
The visualization is part of the lesion-removal service. Do not separately report diagnostic laryngoscopy for the same examination.
When is the laser lesion code a better fit?
Use 31572 when the lesion is destroyed or ablated with a laser. This code describes physical removal through flexible laryngoscopy.
Should modifier 50 be appended for lesions on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code; modifier 50 should not be used.
What should the operative note describe?
Document the lesion's laryngeal location, the flexible endoscopic approach, how the lesion was removed, and the outcome. The record should distinguish removal from biopsy, laser destruction, or foreign-body extraction.
How are related endoscopies handled when performed together?
CMS endoscopy-family pricing applies when related endoscopies are performed together. The code has a 0-day global period, including same-day preoperative and postoperative care.
