What 31511 covers

An otolaryngologist uses indirect laryngoscopic visualization to locate and remove a foreign object lodged in the larynx. The code fits an extraction performed through this indirect approach, rather than removal during direct operative laryngoscopy. It is a focused therapeutic service, not a diagnostic-only examination. Medicare claims for this service in 2024 were reported in facility settings.

Document the laryngeal location of the object, the indirect visualization approach, and the extraction performed. The 0-day global period includes same-day preoperative and postoperative care. When related endoscopies are performed together, CMS endoscopy family pricing applies. A bilateral adjustment is not appropriate. CMS does not pay an assistant at surgery for this service, and co-surgeons and team surgery are not permitted.

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.

31511 billing questions

How does this differ from code 31530?

Code 31511 describes foreign body removal using indirect laryngoscopic visualization. Code 31530 is the direct laryngoscopy approach for removal.

When should code 31531 be considered instead?

Use 31531 when foreign body removal is performed by direct laryngoscopy with an operating microscope. The indirect approach is the distinguishing feature of 31511.

Can a diagnostic laryngoscopy be reported with the removal?

A separate diagnostic laryngoscopy is not established by the removal service alone. If related endoscopies are performed together, CMS endoscopy family pricing applies.

What documentation supports reporting 31511?

Record that a foreign object was present in the larynx, that the clinician used indirect laryngoscopic visualization, and that the object was removed.

Can modifier 50 or an assistant-at-surgery claim be used?

No bilateral adjustment applies, so modifier 50 is inappropriate. CMS does not pay an assistant at surgery for this code.

What does the 0-day global period include?

Same-day preoperative and postoperative care is included in the procedure payment.

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.
