About 92653: Neurodiagnostic auditory evoked potential study
Reports neurodiagnostic auditory evoked potential testing with interpretation when the clinical question concerns auditory nerve or brainstem function.
This service records and analyzes electrical responses along the auditory pathway after sound stimulation. Auditory brainstem response testing is a common example when the clinical question is neurologic function, such as whether responses suggest abnormal auditory nerve or brainstem conduction, rather than simply determining hearing thresholds. Audiologists commonly perform the test in an office or hospital outpatient setting, with a physician or audiologist interpreting and documenting the findings as appropriate.
Report the code for the neurodiagnostic study with its interpretation and report. The record should support the neurologic purpose of testing and include the testing approach, relevant response findings, and clinical interpretation. Distinguish this service from AEP testing intended to determine hearing status or estimate thresholds at multiple frequencies. CMS prices this code as bilateral; reporting modifier 50 does not increase payment.

92653 billing questions
How is this different from 92651?
92653 is for neurodiagnostic evaluation of auditory pathway function. Use 92651 when the study is intended to determine hearing status.
When would 92652 be more appropriate?
Use 92652 when the purpose is estimating hearing thresholds at multiple frequencies. Use 92653 when the clinical question is neurodiagnostic rather than threshold estimation.
Should modifier 50 be appended?
CMS prices 92653 as bilateral, and modifier 50 does not increase payment.
What documentation supports the neurodiagnostic purpose?
Document the reason for testing, the auditory responses obtained, and the interpretation relating findings to auditory nerve or brainstem function.
How does 92653 differ from screening code 92650?
92650 describes auditory evoked potential screening. 92653 is for a neurodiagnostic study with interpretation and a report.
