What 92518 covers

Ocular vestibular evoked myogenic potential testing records reflex responses from muscles around the eyes after sound or vibration stimuli. Electrodes placed beneath the eyes capture the responses, which help assess vestibular function, including the utricular pathway. Audiologists commonly perform the test in audiology or otolaryngology settings, with the findings interpreted and reported as part of the service.

Use this code when the service is ocular VEMP testing with interpretation and a report, rather than cervical VEMP alone or testing both cervical and ocular responses. The record should identify the test performed and include the measured responses, interpretation, and report. CMS pricing treats this code as bilateral; modifier 50 does not increase payment.

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.
