Official Description

Auditory evoked potentials for evoked response audiometry and/or testing of the central nervous system; limited

© Copyright 2025 American Medical Association. All rights reserved.

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.

1. Indications

The procedure associated with CPT® Code 92586 is indicated for the evaluation of various auditory and neurological conditions. The following are the explicitly provided indications for performing this limited auditory evoked potentials examination:

  • Hearing Loss - The procedure is utilized to assess the presence and extent of hearing impairment.
  • Acoustic Neuroma - This test helps in identifying the presence of this benign tumor on the vestibulocochlear nerve, which can affect hearing and balance.
  • Vestibular Schwannoma - Similar to acoustic neuroma, this condition involves a tumor that can impact auditory function and is evaluated through this procedure.

2. Procedure

The procedure for CPT® Code 92586 involves several key steps that are essential for accurately measuring the auditory brainstem response. Each step is designed to ensure that the test results are reliable and informative.

  • Step 1: Patient Preparation - The patient is positioned comfortably, and the area around the ears and scalp is prepared for electrode placement. This may involve cleaning the skin to ensure good electrical contact.
  • Step 2: Electrode Placement - Surface electrodes are strategically placed on the patient's forehead (vertex of the scalp) and earlobes. Alternatively, electrodes may be positioned on the forehead, nape of the neck (inverting), and either the shoulder or cheek to capture the brain's electrical responses accurately.
  • Step 3: Auditory Stimulus Presentation - Auditory stimuli, typically in the form of click sounds, are delivered through earphones or headphones. These sounds are designed to elicit a response from the auditory pathways.
  • Step 4: Response Measurement - The electrical activity generated in response to the auditory stimuli is recorded by the electrodes. The amplitude of the signal is averaged over time, similar to an EEG recording, to enhance the clarity of the results.
  • Step 5: Data Interpretation - The recorded waveforms are analyzed, and a written report of the findings is generated. This report provides insights into the functionality of the auditory pathways and any potential abnormalities.

3. Post-Procedure

After the completion of the auditory evoked potentials examination, patients may resume their normal activities immediately, as there are typically no significant side effects associated with the procedure. The results of the test are usually interpreted by a qualified healthcare professional, who will provide a detailed report outlining the findings. This report may be used to guide further diagnostic evaluations or treatment options based on the identified auditory or neurological conditions. Follow-up appointments may be scheduled to discuss the results and any necessary next steps in management.
