What 92531 covers

This study assesses spontaneous nystagmus, involuntary rhythmic eye movement present without a positioning maneuver; gaze may also be assessed. It is one focused element of vestibular testing for patients evaluated for balance or dizziness symptoms. Audiologists and other clinicians who perform vestibular evaluations may report it in a balance assessment. The code distinguishes the unrecorded study from the recorded spontaneous nystagmus test, 92541.

Medicare assigns 92531 physician fee schedule status B. Medicare does not pay the code separately; its payment is included in payment for other services. Report 92531 for the spontaneous nystagmus study without recording, rather than the recorded counterpart, when that is the service performed.

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.
