What 31578 covers

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.
