Do You Have the Right Equipment for These ABR and VEMP Tests?

by Adam Dawson

The American Academy of Audiology (AAA) and the American Speech-Language-Hearing Association (ASHA) recently published seven new CPT codes for Auditory Evoked Potentials (AEP) and Vestibular Evoked Myogenic Potentials (VEMP) tests.

These codes were approved by the American Medical Association (AMA) CPT Editorial Panel for implementation on January 1, 2021.

Out of the seven new codes, four are specifically for AEP testing and three are for VEMP testing. The purpose of these additions is to help better define and describe the work being performed.


The four new AEP CPT codes are:


  • 92650 – Screening of AEP with broadband stimuli, automated analysis
  • 92651 – for hearing status determination, broadband stimuli, with interpretation and report 
  • 92652 – for threshold estimation at multiple frequencies, with interpretation and report 
  • 92653 – neurodiagnostic, with interpretation and report 

In addition, the groups developed three new codes to simplify reporting of VEMP testing. 


The new VEMP CPT codes are:


  • 92517 – VEMP testing, with interpretation and report; cervical (cVEMP)
  • 92518 – ocular (oVEMP)
  • 92519 – cervical (cVEMP) and ocular (oVEMP)


These Instruments Can Perform All These Tests


Interacoustics Eclipse

A future-proof, modular instrument capable of performing AEP, ASSR, VEMP, and OAE testing, the Interacoustics Eclipse packs a ton of power into a compact package. It has the largest number of clinically relevant features of any AEP device today and provides an unparalleled blend of parameter flexibility and user-friendliness.

Whatever your challenge may be, the Eclipse enables you to focus on the job at hand with the assistance of dedicated software modules for all facets of auditory evoked potentials. It is designed to fit seamlessly into your everyday workflow and to offer complete reliability and perfect results. Additionally, the oVEMP and cVEMP tests measure and analyze the vestibular evoked myogenic potential generated by a loud stimulus.

GSI Audera Pro

Compact and powerful, the new GSI Audera Pro is a compact, yet versatile device, capable of performing all standard evoked potential tests. Some of the featured new tests include: P300/MMN, ASSR Binaural testing, TEOAE, and Speech Stimuli for ABR. In comparison to its predecessor, the hardware has been updated to provide a smaller footprint, an integrated pre-amplifier, lightweight cables, and the GSI OAE probe. 

The Audera Pro includes waveform analysis tools such as Area Ratio for ECochG, application of digital filters, the option to split alternating waveform into rarefaction and condensation components, cross correlation of waveforms, and automatic SNR and RN calculation. It comprehensively evaluates, identifies, documents, and diagnoses auditory and vestibular disorders on patients of all ages.

Additionally, it allows you to combined reports between modules (i.e. ABR, ASSR, OAE, VEMP etc.).


ABR Features

  • Binaural testing
  • Save time and increase clinical confidence with CE-Chirp stimuli
  • eABR, ECochG, ABR, MLR, LLR, and SN10
  • P300 and MMN protocols 
  • Traditional test stimuli of click and tone bursts 
  • Bayesian weighting
  • Split alternating wave form into rarefaction and condensation components
  • Cross correlation of waveforms
  • Automatic SNR and RN calculation


VEMP Features

  • Analyze cervical and optical VEMP recording
  • Automatically calculates asymmetry ratio
  • Saving automatically creates report in EP module
  • Rectification of cVEMP waveforms
  • Allows for viewing each sweep in recording
  • Allows for excluding sweeps from the grand average when EMG activity is greater or less than 1, 1.5, or 2 SD’s
