What 92520 covers

This service assesses how the larynx produces voice using objective aerodynamic and acoustic measures. A voice-specialized speech-language pathologist or an otolaryngology team may perform it in an outpatient voice clinic or another setting equipped for voice testing. It can help characterize concerns such as persistent hoarseness or changes in vocal function, including during assessment before or after treatment.

Select this code when the documented service is laryngeal function testing, rather than a behavioral or qualitative assessment of voice alone. The record should identify the testing performed, relevant findings or measurements, and the clinical reason for the study. Report the service based on the testing actually completed and documented. CMS assigns physician fee schedule work, practice expense, and malpractice relative value units, with practice expense values differing between office and facility settings.

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.

92520 billing questions

How does 92520 differ from 92524?

92520 represents objective laryngeal function testing, including aerodynamic or acoustic measures. 92524 is a behavioral and qualitative analysis of voice and resonance.

Does a laryngeal scope replace this testing?

No. A scope documents anatomic visualization, while 92520 represents functional voice testing. Report each service only when it was separately performed and documented.

Who typically performs 92520?

A speech-language pathologist specializing in voice or an otolaryngology team may perform the testing in an outpatient voice clinic or similar setting.

What documentation supports reporting 92520?

Document the clinical reason for testing, the aerodynamic or acoustic procedures performed, and the resulting measurements or findings.

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.
