CPT® Code 92563

The tone decay test, identified by CPT® Code 92563, is a specialized auditory assessment designed to evaluate sensorineural hearing loss. This test involves the use of earphones to deliver a continuous tone that is generated at the patient's individual hearing threshold. The primary objective of the tone decay test is to determine the patient's ability to perceive the tone over a specified duration, which is typically up to one minute. During the test, if the patient reports that they can no longer hear the tone before the one-minute mark is reached, the intensity of the tone is increased by 5 decibels. This process is repeated, allowing the clinician to assess the patient's auditory response to varying sound levels. The test continues until the patient is able to hear the tone for the full minute without further adjustments. Should the tone need to be increased by more than 5 decibels above the initial threshold for the patient to maintain perception, it may indicate the necessity for additional, separately reportable tests aimed at further evaluating sensorineural hearing loss. The results of the tone decay test, along with a comprehensive written interpretation of the findings, are provided to assist in the diagnostic process.
