What 92640 covers
An audiologist assesses an auditory brainstem implant and adjusts its stimulation map to support the recipient’s access to sound. The work may include checking electrode responses and refining stimulation levels based on the recipient’s responses. It is performed for people who have received an auditory brainstem implant, often in an audiology or implant-programming clinic associated with an otolaryngology practice.
Report this service for programming of an auditory brainstem implant, not for programming a cochlear implant. Documentation should identify the implanted device and record the assessment and programming performed, including relevant setting changes and the recipient’s responses. CMS prices this code as bilateral; appending modifier 50 does not increase payment. The assessment described here is tied to implant programming; separately performed diagnostic work requires its own support and applicable code.

How to choose
- 92603Implant analysis
- 92603 is for cochlear implant analysis and programming in a patient seven years or older. Use 92640 when the implanted device is an auditory brainstem implant.
- 92604Cochlear implant programming
- 92604 describes subsequent reprogramming of a cochlear implant in a patient seven years or older. It is not the code for programming an auditory brainstem implant.
- 92651Auditory evoked potentials
- 92651 is an auditory evoked potential service used to determine hearing status. 92640 is for assessing and programming an auditory brainstem implant.
92640 billing questions
How does this differ from cochlear implant programming?
Use 92640 for programming an auditory brainstem implant. Cochlear implant programming is reported with the cochlear implant analysis and programming codes, selected by the patient’s age and whether the service is initial or subsequent.
Should modifier 50 be appended for bilateral pricing?
CMS prices 92640 as bilateral, and modifier 50 does not increase payment. Do not append it to seek additional payment.
What should the record support?
Document that the device is an auditory brainstem implant, the assessment performed, programming changes made, and the recipient’s responses. The record should distinguish programming from a standalone hearing evaluation.
Can an audiologist report this service?
Yes. Audiologists commonly perform auditory brainstem implant assessment and programming in an implant-programming clinic.
Is this the code for an auditory evoked potential test?
No. 92640 covers assessment and programming of an implanted auditory brainstem device; auditory evoked potential codes describe electrophysiologic testing.
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.
