What 92588 covers
An audiologist uses a small probe in the ear canal to present sounds and record the cochlea’s resulting otoacoustic emissions. This comprehensive assessment samples multiple frequencies and helps evaluate outer hair cell function, including when an infant or another patient cannot reliably complete behavioral testing. It provides objective information about cochlear responses, rather than behavioral hearing thresholds.
Report the comprehensive service when the evaluation meets the code’s frequency scope and includes interpretation and a report; retain the test results and interpretation in the record. A limited evoked otoacoustic emission evaluation is a different service. CMS separately prices the professional interpretation and the technical equipment-and-staff portions: report modifier 26 for the professional component or TC for the technical component, or report the global service without either modifier. CMS pricing treats the service as bilateral, so modifier 50 does not increase payment.

How to choose
- 92587Otoacoustic emissionsLimited frequency assessment
- Use 92588 for the comprehensive evaluation covering at least 12 frequencies with interpretation and a report; 92587 is the limited evaluation.
- 92557Comprehensive hearing testAir, bone, and speech testing
- 92557 assesses behavioral pure-tone and speech responses. 92588 measures otoacoustic emissions and is useful when behavioral responses are unavailable or unreliable.
- 92567TympanometryMiddle ear pressure and mobility
- 92567 measures middle-ear function with tympanometry; 92588 records cochlear emissions. They assess different parts of the auditory system.
92588 billing questions
How does this differ from 92587?
92588 is for a comprehensive evaluation covering at least 12 frequencies, with interpretation and a report. 92587 is the limited evaluation, generally covering 3–6 frequencies.
Can the professional and technical portions be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical portion involving equipment and staff. Without either modifier, the claim represents the global service.
Should modifier 50 be reported?
No. CMS pricing already treats 92588 as bilateral, and modifier 50 does not increase payment.
What documentation supports the comprehensive service?
Keep the frequency-specific test results, evidence that the comprehensive frequency scope was performed, and the interpretation and report. The record should make clear that the service was more than a limited evaluation.
Is this the same as a behavioral hearing test?
No. Otoacoustic emission testing records cochlear responses to sound; behavioral audiometry measures responses from the patient and can establish hearing thresholds. The tests answer different clinical questions.
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.
