Audiology
About 92588: Comprehensive otoacoustic emission evaluation
Reports a comprehensive, multi-frequency otoacoustic emission assessment with interpretation, commonly used to evaluate cochlear function when behavioral hearing testing is limited.
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.
CMS billing rules for 92588
- Professional and technical components
- Diagnostic test with a professional component (modifier 26, interpretation) and a technical component (modifier TC, equipment and staff); billing without a modifier is the global service.
- Bilateral procedures
- The code is already priced as bilateral; modifier 50 does not increase payment.

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 indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
