    CPT 92552: Pure-Tone Audiometry Threshold Detection

    Medicare pays $42 on average nationally for this procedure.

    CPT code 92552 describes pure-tone audiometry air and/or bone conduction testing in which the provider presents a series of tones at varying intensities to determine the patient’s lowest hearing thresholds; this is an audiometric assessment typically performed as an outpatient diagnostic hearing test in an audiology clinic, ENT office, or hospital outpatient department and is billed as a discrete hearing threshold evaluation procedure.

    Clinical & Coding Specifications

    Clinical Context

    A typical adult patient presents to an outpatient audiology or otolaryngology clinic reporting progressive difficulty hearing conversations, especially in noisy environments, over several months. The provider documents a focused history including onset, asymmetry, prior noise exposure, ototoxic medication use, tinnitus, and ear pain. Physical exam includes otoscopy to inspect the external canal and tympanic membrane. The clinician performs pure-tone audiometry (92552) in a sound-treated booth using calibrated audiometric equipment to determine air-conduction thresholds across standard frequencies and identify the softest levels the patient can detect. Test results guide further testing (speech audiometry, bone conduction, tympanometry) or management (hearing aids, medical or surgical referral). Typical sites of service are outpatient audiology clinics, ENT offices, or hospital outpatient departments. The service type is diagnostic auditory threshold assessment (pure-tone air-conduction threshold testing).
