CPT® Code 92561

Deleted

The Bekesy audiometry test, identified by CPT® Code 92561, is a specialized diagnostic procedure used to assess hearing capabilities through pure tone air conduction. This test is unique in that it allows the patient to control the intensity of the auditory stimulus, which differentiates it from standard hearing tests. The primary purpose of Bekesy audiometry is to help distinguish between cochlear and neural origins of hearing loss, providing valuable insights into the patient's auditory function. The procedure is typically conducted in a soundproof environment, utilizing earphones to ensure that each ear can be evaluated independently. During the test, the auditory stimulus is presented across the full range of audible frequencies, from low to high pitches. The patient is equipped with a button that they press to indicate when they can hear the sound. As long as the button is pressed, the sound intensity gradually decreases. Once the patient can no longer hear the sound and releases the button, the intensity begins to increase again. This back-and-forth process continues through all tested frequencies, allowing for a comprehensive assessment of hearing ability. The test may utilize both continuous and interrupted tones, and the results are meticulously recorded, resulting in a zigzag tracing that reflects the patient's hearing thresholds. Following the completion of the test, the findings are interpreted, and a detailed written report is generated to summarize the results. It is important to note that CPT® Code 92560 should be used when Bekesy audiometry is performed as a screening test, while CPT® Code 92561 is reserved for diagnostic testing.
