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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

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.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
