What 31577 covers
An otolaryngologist typically performs this operative procedure by passing a laryngoscope through the mouth to visualize the larynx and retrieve a lodged object with instruments. It is commonly performed in an operating room or ambulatory surgery setting, often under anesthesia. The target is a foreign body in the larynx, rather than a lesion being excised or a specimen being taken for biopsy.
Report the procedure when the operative note identifies the laryngeal foreign body and documents its removal. The code has a 0-day global period, so same-day preoperative and postoperative care is included. CMS applies endoscopy-family pricing when related endoscopies are performed together. Modifier 50 is inappropriate for this service. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted under the CMS rules for this code.

31577 billing questions
How is this different from diagnostic laryngoscopy?
Use 31577 when the laryngoscopy is operative and a foreign body is removed. A diagnostic examination without removal is represented by 31575.
When should 31578 be considered instead?
31578 describes operative removal of a laryngeal lesion. Use 31577 for removal of a foreign object, not excision of a lesion.
Can a biopsy be reported as 31577?
No. When tissue is sampled for diagnostic examination rather than a foreign body being removed, consider 31576.
Should modifier 50 be appended for bilateral work?
No. CMS identifies modifier 50 as inappropriate for this code because of its descriptor or anatomy.
What documentation supports reporting 31577?
Document the foreign body's laryngeal location, the operative visualization, and the retrieval performed. If an assistant-at-surgery claim is submitted, document medical necessity.
