CPT code 92545: Vestibular test, oscillating target tracking2026 Medicare rate & RVUs

Medicare pays $16.70 for 92545 nationally in the office. Local office rates run $15.25–$20.93.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
