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.

92541 billing questions
How does 92541 differ from 92531?
92541 describes the spontaneous and gaze assessment with recording. The 92531 code is the nearby option for the corresponding study without recording.
When should 92540 be considered instead?
92540 represents a basic vestibular evaluation that includes spontaneous nystagmus, positional nystagmus, optokinetic nystagmus, and oscillating tracking tests. Use 92541 for the individual recorded spontaneous nystagmus assessment.
Which modifier identifies interpretation?
Append modifier 26 when billing only the professional interpretation. Modifier TC identifies the technical service, and billing without either modifier represents the global service.
What should the record support?
Document that spontaneous and gaze-related eye movements were assessed and recorded, along with the findings and the interpretation when the professional component is billed.
Is this the positional nystagmus test?
No. 92541 addresses spontaneous nystagmus, including gaze assessment; 92542 is the recorded positional nystagmus test.
