What 92544 covers
The patient watches a moving visual pattern while a clinician observes or records the resulting rhythmic eye movements. The test examines how the eyes respond to visual motion and can help characterize oculomotor and vestibular function in patients evaluated for vertigo, imbalance, or suspected vestibular dysfunction. Audiologists and otolaryngology practices commonly perform it in a vestibular testing setting.
Report 92544 when optokinetic stimulation is performed as an individual test; distinguish it from smooth-pursuit tracking, which evaluates eye movement while following a target. Record the test performed and findings, including the patient’s eye-movement response to the visual stimulus. Medicare recognizes professional and technical components: use modifier 26 for interpretation, modifier TC for equipment and staff, or neither modifier when billing the global service. When the defined basic vestibular evaluation is reported with 92540, its component tests are not separately unbundled.
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.

92544 billing questions
What does this test measure?
It assesses the eye movements produced when the patient views a moving visual pattern. The response helps characterize visual-motion and vestibular-related function.
How is 92544 different from the oscillating tracking test?
92544 evaluates eye movements in response to a moving visual field. The oscillating tracking test, 92545, assesses the patient’s ability to follow a moving target.
Can 92544 be reported separately with 92540?
No. The basic vestibular evaluation represented by 92540 includes the optokinetic test as one of its component tests; do not separately unbundle 92544 from that evaluation.
Which modifiers identify the test components?
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.
What documentation supports reporting 92544?
Document that optokinetic visual stimulation was performed and record the observed or recorded eye-movement response. The record should distinguish this stimulus-response test from smooth-pursuit tracking.
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.
