CPT® Code 0212T

The CPT® Code 0212T refers to a comprehensive audiometry threshold evaluation and speech recognition test that is automated. This procedure involves the use of a computerized system to conduct hearing tests, which enhances the accuracy and efficiency of the evaluation process. During the test, ambient noise microphones are strategically placed near the patient's ears to monitor environmental sounds, while ear inserts are utilized to facilitate the testing. These inserts are designed to fit comfortably in the ear without completely occluding the ear canal, allowing for effective sound transmission. The ear inserts connect to transducers and a bone oscillator positioned outside the ear, which are essential for conducting both air and bone pure tone audiometry. The air pure tone audiometry component assesses the patient's hearing sensitivity by determining the softest sounds that can be detected at least 50 percent of the time. The results are visually represented on a computer screen, providing a clear graphic depiction of the patient's hearing thresholds. In contrast, the bone pure tone audiometry evaluates hearing through vibrations transmitted via the bones of the skull to the cochlea, allowing for an assessment of auditory pathways in the brain. This also results in a graphical representation of the bone conduction thresholds. Additionally, the automated speech audiometry aspect of the test measures the lowest intensity of speech that the patient can hear at least 50 percent of the time. The computerized system scores this threshold, providing valuable data on the patient's speech recognition capabilities. Speech recognition, also known as speech discrimination or word recognition, involves the patient repeating a series of words presented by the automated program. The computer then calculates the percentage of words that the patient correctly repeats, offering insights into their auditory processing abilities. Overall, this comprehensive evaluation is crucial for diagnosing hearing impairments and determining appropriate interventions.
