Common Language Description

Auditory evoked potentials for evoked response audiometry and/or testing of the central nervous system, as described by CPT® Code 92586, is a specialized diagnostic procedure aimed at evaluating auditory function and identifying potential neurological conditions. This procedure is particularly useful in assessing hearing loss and can help in the diagnosis of specific conditions such as acoustic neuroma or vestibular schwannoma. The testing involves measuring the brain's electrical activity in response to auditory stimuli, which is crucial for understanding the integrity of the auditory pathways and the central nervous system's response to sound. Unlike the comprehensive auditory evoked response examination denoted by CPT® Code 92585, which includes a broader range of responses, the limited examination under CPT® Code 92586 focuses specifically on the brainstem response. This targeted approach allows for a quicker assessment while still providing valuable information regarding the auditory system's functionality.
