What 92545 covers
This vestibular test records eye movements while the patient follows a target moving back and forth. It assesses smooth visual tracking and related oculomotor function in patients with dizziness, vertigo, or imbalance. Audiologists and vestibular laboratory staff commonly perform it as part of an ENG or VNG evaluation; a qualified clinician reviews the recorded responses and documents the findings.
Report the service when the oscillating-target tracking test is performed, rather than substituting a test that measures responses to a moving visual field or chair rotation. Documentation should identify the test performed, the recorded eye-movement responses, and the interpretation. CMS recognizes professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies equipment and staff, and billing without a modifier represents the global service.

How to choose
- 92544Vestibular testOptokinetic response
- Use 92545 for eye movements recorded while following an oscillating target; 92544 evaluates optokinetic responses to a moving visual field.
- 92546Rotational testSinusoidal chair rotation
- Use 92545 for visual tracking of an oscillating target. Code 92546 evaluates responses during sinusoidal rotational chair testing.
- 92540Vestibular evaluationBasic test battery
- Code 92540 describes a basic vestibular evaluation that includes oscillating tracking testing; 92545 identifies the tracking test itself.
92545 billing questions
How is this different from the optokinetic nystagmus test?
This test records eye movements as the patient follows an oscillating target. The optokinetic test evaluates the response to a moving visual field.
How is this different from sinusoidal rotational testing?
Oscillating tracking uses a visual target to assess eye movements. Sinusoidal rotational testing evaluates responses while the patient undergoes chair rotation.
Can the professional and technical components be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service, including equipment and staff. Without either modifier, the claim represents the global service.
Is this test included in the basic vestibular evaluation?
The basic vestibular evaluation, code 92540, includes oscillating tracking testing. Do not separately report the same test as though it were a distinct additional service.
What documentation supports reporting this test?
Document that the patient underwent oscillating-target tracking, the eye-movement responses recorded, and the interpretation. The record should distinguish this procedure from visual-field motion or rotational testing.
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.
