Vestibular testing
About 92540: Basic vestibular evaluation
Reports a basic vestibular test battery assessing eye movements and positional responses during evaluation of dizziness, vertigo, or balance symptoms.
This code represents a basic vestibular battery that evaluates eye movements and responses to changes in gaze, visual tracking, and head or body position. The included test elements are spontaneous nystagmus with gaze and fixation, positional nystagmus, oscillating tracking, and optokinetic nystagmus. Audiologists and otolaryngology or neurotology clinicians commonly perform or interpret these tests in outpatient settings when assessing dizziness, vertigo, or balance complaints.
Report 92540 when the documented service includes the basic battery, rather than when only an individual test is performed. The record should identify the tests conducted and support the clinician’s interpretation of the findings. CMS recognizes professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies equipment and staff, and reporting without either modifier represents the global service. The listed modifiers are separately priced under the CMS facts for this code.
CMS billing rules for 92540
- Professional and technical components
- Diagnostic test with a professional component (modifier 26, interpretation) and a technical component (modifier TC, equipment and staff); billing without a modifier is the global service.

92540 billing questions
When should 92540 be chosen instead of 92541 or 92542?
Use 92540 for the basic battery, which includes spontaneous and positional nystagmus testing along with tracking and optokinetic testing. Use an individual test code when only that standalone test is performed.
Can the individual tests included in 92540 also be reported separately?
The basic battery includes spontaneous nystagmus, positional nystagmus, oscillating tracking, and optokinetic testing. Do not separately report those same included test elements as standalone services for the same evaluation.
What do modifiers 26 and TC identify for this code?
Modifier 26 reports the professional interpretation, while modifier TC reports the technical service, including equipment and staff. Without either modifier, the claim represents the global service.
What documentation supports reporting the basic battery?
Document which included test elements were performed and the findings and interpretation. A record describing only one component test supports consideration of its individual code instead.
Does 92540 include caloric testing?
No. Caloric vestibular testing is a separate test service; it is not one of the four elements in the basic battery.
