CPT® Code 0209T

Automated pure tone audiometry is a diagnostic procedure that employs a computerized system to assess an individual's hearing capabilities. This method involves the use of ambient noise microphones strategically positioned near the patient's ears to capture sound levels accurately. During the test, ear inserts are placed in the patient's ears; these inserts are connected to transducers and a bone oscillator that is positioned externally. It is important to note that the ear inserts do not completely block the ear canal, allowing for a more natural assessment of hearing. The automated audiometry device is programmed to conduct specific tests, which are designed to evaluate the patient's auditory sensitivity. In the context of CPT® Code 0208T, the focus is on automated pure tone air audiometry, which measures the softest sounds that a patient can hear at least 50 percent of the time, providing a threshold for hearing sensitivity. The results are visually represented on a computer screen, illustrating the patient's hearing capabilities. CPT® Code 0209T expands upon this by incorporating both air and bone conduction testing. The air conduction test is performed first, followed by a secondary test that evaluates hearing through vibrations transmitted via the bones of the skull to the cochlea, and subsequently through the auditory pathways to the brain. The outcomes of both tests are graphically displayed, allowing for a comprehensive understanding of the patient's auditory thresholds.
