What 92541 covers
This vestibular test records involuntary eye movements that occur spontaneously and during gaze assessment. Audiologists, otolaryngologists, and other clinicians performing vestibular evaluations may use electronystagmography or videonystagmography equipment in an audiology clinic, ENT practice, or vestibular laboratory. Results can help characterize eye-movement findings in patients evaluated for dizziness, vertigo, or imbalance.
Report 92541 for the recorded spontaneous nystagmus assessment, including gaze; documentation should identify the test performed and its recorded findings. CMS recognizes a professional component for interpretation and a technical component for equipment and staff: report modifier 26 for interpretation, modifier TC for the technical service, or neither modifier for the global service. The recorded assessment differs from a basic vestibular evaluation code that represents a defined combination of tests.
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.

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.
