CPT® Code 92650

Auditory evoked potentials (AEP) refer to the measurable electrophysiological responses generated by the brain in reaction to auditory stimuli, such as acoustic pulses, brief tones, or short bursts of broadband clicks. These responses manifest as voltage fluctuations that occur following the presentation of sound stimuli. The primary purpose of AEP testing is to evaluate auditory neurological function and identify any potential hearing loss. The specific procedure associated with CPT® Code 92650 involves the screening of auditory evoked responses using broadband stimuli, which is particularly relevant for universal newborn hearing screenings. During this screening, sound stimuli are presented to each ear, and data is collected regarding the brain's evoked potential responses. This process is facilitated by an automated analysis conducted by a screening device, which utilizes a computer algorithm to interpret the data. The healthcare provider is responsible for monitoring electrode impedance and ensuring the presence or absence of valid responses as dictated by the algorithm. Ultimately, the screening yields a pass or refer result, indicating whether further evaluation is necessary. For cases where a child is referred for additional testing, CPT® Code 92651 is utilized to report post-screening or follow-up assessments, which focus on determining the auditory brainstem response (ABR) to the broadband sound stimuli.
