CPT® Code 92584

Electrocochleography, denoted by CPT® Code 92584, is a diagnostic procedure utilized to assess the functionality and conditions of the inner ear. This procedure is particularly relevant for evaluating disorders such as Meniere's disease and endolymphatic hydrops, both of which are characterized by abnormal fluid accumulation and pressure changes within the inner ear. During the electrocochleography process, a specialized electrode is affixed to the patient's forehead, while foil-covered earphones are inserted into the ear canals. These earphones emit sound stimuli that provoke a response from the cochlea, the auditory portion of the inner ear. The electrode captures the resultant electrical potentials generated by the cochlear activity in response to the sound. These electrical signals are then recorded and displayed digitally as a waveform, which provides valuable insights into the inner ear's condition. The resulting digital waveform is meticulously analyzed, and a comprehensive written report is generated to convey the findings of the evaluation.
