About 92584: Electrocochleography response testing
Electrocochleography records sound-evoked electrical responses from the cochlea and auditory nerve, often during evaluation of suspected endolymphatic hydrops.
Electrocochleography records electrical responses generated by the cochlea and auditory nerve after sound stimulation. An audiologist or otolaryngologist may perform it in an audiology clinic or hospital setting, commonly as part of evaluating suspected endolymphatic hydrops in a patient with symptoms such as episodic vertigo and fluctuating hearing. Electrodes may be placed in the ear canal or against the tympanic membrane, depending on the technique used.
Report 92584 for the electrocochleographic study, rather than for routine air- and bone-conduction audiometry, tympanometry, or otoacoustic emissions testing. Documentation should identify the clinical indication, ears tested, method or electrode placement, recorded responses, and interpretation. The CMS fee schedule prices this code as bilateral, so modifier 50 does not increase payment. When other audiologic tests are performed during the same encounter, document each test separately.

92587 is limited otoacoustic-emission testing, assessing cochlear outer hair cell responses. It is not electrocochleography.
$32.54–$33.68
92588 is comprehensive otoacoustic-emission testing. It evaluates emissions rather than the electrical potentials recorded in electrocochleography.

92584 billing questions
When is 92584 appropriate instead of a standard hearing test?
Use 92584 for recording sound-evoked cochlear and auditory nerve potentials, such as during evaluation for suspected endolymphatic hydrops. Pure-tone or speech audiometry measures hearing thresholds or speech recognition instead.
Should modifier 50 be appended when both ears are tested?
No. CMS prices 92584 as a bilateral service, and modifier 50 does not increase payment.
Can audiometry or tympanometry be reported at the same visit?
They may be reported when those tests are separately performed and documented. The record should distinguish their results from the electrocochleographic responses.
How does 92584 differ from evoked auditory testing?
Electrocochleography records electrical potentials from the cochlea and auditory nerve. Evoked auditory testing codes such as 92587 and 92588 describe otoacoustic-emission testing, which evaluates cochlear outer hair cell responses.
What documentation supports reporting 92584?
Document the indication, ears tested, electrode method or placement, responses obtained, and clinical interpretation. The findings should support that electrocochleography—not only routine audiometry—was performed.
