What 92511 covers

An ENT clinician typically passes a flexible or rigid endoscope through a nostril to examine the posterior nasal space and nasopharynx, including the area around the eustachian tube openings. Common reasons include persistent nasal obstruction, suspected adenoid enlargement, a visible or suspected nasopharyngeal lesion, or evaluation of unilateral middle-ear effusion. The service may be performed in an office or facility setting.

Report 92511 when the documented examination visualizes the nasopharynx; an examination limited to the nasal cavity or directed at the larynx represents a different service. The record should identify the indication, endoscopic approach, structures examined, and findings. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment requires documentation of medical necessity; 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.

92511 billing questions

How is 92511 different from diagnostic nasal endoscopy?

92511 is selected when the documented endoscopic examination reaches the nasopharynx. A nasal endoscopy code such as 31231 is directed to examination of the nasal cavity.

Can modifier 50 be used when both sides are examined?

No. CMS identifies bilateral adjustment as inappropriate for 92511; do not use modifier 50 to represent examination through both nostrils.

What documentation supports reporting 92511?

Document the clinical reason for the examination, the endoscopic approach, the nasopharyngeal structures visualized, and the findings. The note should support that the examination extended beyond the nasal cavity.

Is same-day preoperative or postoperative care included?

Yes. The code has a 0-day global period, which includes same-day preoperative and postoperative care.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment requires documented medical necessity. CMS does not permit co-surgeons or team surgery for this code.

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.
