What 92512 covers

This study evaluates how air moves through the nose, including measurements of airflow or resistance during breathing. Rhinomanometry is a typical method. Otolaryngologists and other clinicians who evaluate nasal obstruction may use it in an office or testing setting when symptoms such as persistent congestion or impaired nasal breathing call for an objective functional assessment.

Report 92512 for the nasal function study, not for visual inspection alone. The record should identify the clinical question, testing method, relevant conditions during testing, measured findings, and interpretation. These details distinguish functional measurement from nasal endoscopy or examination and support why the study was performed. Report the completed study rather than separate units for individual breaths or readings.

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.

92512 billing questions

How does 92512 differ from nasopharyngoscopy?

92512 measures nasal function, such as airflow or resistance. Nasopharyngoscopy (92511) documents endoscopic visualization of the nasopharynx.

Can 92512 be reported with nasal endoscopy?

A functional study and nasal endoscopy describe different services. When both are performed, document the measurements separately from the endoscopic findings.

What should the record include?

Document the reason for testing, the method used, the findings, and their interpretation. Include clinical context that supports evaluating nasal airflow or resistance.

Are individual readings billed as separate units?

Report the completed nasal function study, not each breath, measurement, or instrument reading as a separate unit.

Does a visual nasal examination alone support 92512?

No. The service is functional testing; visual inspection without nasal airflow or resistance measurement describes a different service.

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.
