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.
