Evaluation of auditory function for surgically implanted device(s) candidacy or postoperative status of a surgically implanted device(s); first hour

The evaluation of auditory function for surgically implanted device candidacy or postoperative status is a critical process that assesses whether a patient qualifies for devices such as cochlear implants. This evaluation is particularly important for individuals with significant hearing disabilities who may not benefit from traditional hearing aids. The procedure begins with a comprehensive case history that includes an assessment of the patient's hearing loss, any recent changes in their ability to understand speech, and any family history of hearing loss. Additionally, the provider evaluates the current use of hearing aids, checking their functional integrity and determining the effectiveness of any adjustments made to optimize the hearing amplification system.

During the evaluation, the patient is placed in a controlled sound booth, which is equipped with loudspeakers positioned at specific angles to create a spherical coordinate system. This setup allows for precise control over the sound presentation and intensity levels. The assessment involves testing the patient's ability to perceive speech and understand both words and sentences in a quiet environment, with varying intensity levels from the loudspeakers. The testing is further complicated by introducing different levels of background noise to simulate real-world listening conditions. Each ear is tested separately with the amplification device, and then both ears are assessed together to evaluate binaural hearing performance. The results of these tests are scored and interpreted using standard performance measures, which help determine the potential success of an implant. Furthermore, similar evaluations may be conducted postoperatively to monitor auditory function after the surgical placement of the implant. For billing purposes, CPT® code 92626 is reported for the first hour of evaluation, while 92627 is used for each additional 15 minutes of service provided.
