CPT® Code 92577

The Stenger test, classified under CPT® Code 92577, is a specialized auditory assessment designed to evaluate hearing capabilities using spondee words. Spondee words are defined as two-syllable words that are pronounced with equal emphasis on each syllable, such as "airplane," "padlock," and "baseball." This test is conducted using earphones, allowing for a controlled environment where each ear can be tested both separately and simultaneously. The primary objective of the Stenger test is to determine the hearing threshold for each ear by delivering a spondee word at the patient's individual hearing threshold. During the procedure, the patient is instructed to repeat the word and indicate whether it was heard in the right or left ear. In individuals with normal hearing or functional hearing loss, the expected outcome is that a word presented to the right ear at the hearing threshold will be perceived in the right ear, while a word presented to the left ear will be heard in the left ear. When words are delivered simultaneously to both ears at the same hearing threshold, the sound is typically perceived centrally in the head, provided that the sensitivity levels of both ears are equal. However, if there is a discrepancy in sensitivity levels, the sound will be perceived in the ear with the higher sensitivity until the intensity in the less sensitive ear is adjusted to match its hearing threshold. In cases where nonorganic hearing loss is suspected—whether psychogenic or feigned—the Stenger test results will deviate from the expected pattern, indicating a lack of genuine auditory perception. This test is often integrated with other hearing assessments, and patients are generally unaware that the Stenger test is being conducted, as it serves to differentiate between functional and nonorganic hearing loss. The results of the test are documented on an audiogram, and a written interpretation of the findings is provided to ensure clarity and facilitate further evaluation or treatment as necessary.
