Official Description

Pure tone audiometry (threshold); air and bone

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 92553 refers to pure tone audiometry, specifically the assessment of hearing thresholds using both air and bone conduction methods. This audiometric evaluation is essential for determining an individual's hearing sensitivity across a range of frequencies, which is crucial for diagnosing hearing impairments. During the test, patients wear earphones that deliver pure tone sounds at varying frequencies, allowing for the assessment of air conduction hearing. Additionally, bone conduction testing is performed using a bone oscillator placed on the skull, which transmits sound vibrations directly to the inner ear, bypassing the outer and middle ear structures. This dual approach enables clinicians to differentiate between conductive and sensorineural hearing loss. The results of the audiometry are meticulously recorded on an audiogram, providing a visual representation of the patient's hearing ability at different pitches. Following the test, a comprehensive written interpretation of the findings is generated, which aids in further clinical decision-making and management of the patient's auditory health.

1. Indications

The procedure of pure tone audiometry (CPT® Code 92553) is indicated for the following conditions:

  • Hearing Loss Assessment of suspected hearing loss in patients presenting with symptoms such as difficulty hearing conversations, asking for repetitions, or misunderstanding speech.
  • Monitoring Hearing Changes Regular evaluation of hearing thresholds in patients with known hearing impairments or those at risk for progressive hearing loss due to age, noise exposure, or medical conditions.
  • Preoperative Evaluation Assessment of hearing function prior to surgical procedures that may affect auditory structures or in patients undergoing procedures that require anesthesia.
  • Postoperative Assessment Evaluation of hearing function following ear surgeries or interventions to determine the effectiveness of the procedure.

2. Procedure

The procedure for pure tone audiometry (CPT® Code 92553) involves several key steps to ensure accurate assessment of hearing thresholds:

  • Preparation of the Patient The patient is seated in a soundproof room to minimize external noise interference. Earphones are fitted securely to ensure proper sound delivery, and the patient is instructed on how to respond during the test.
  • Air Conduction Testing The audiologist presents a series of pure tone sounds through the earphones at various frequencies, starting from low to high. The patient is asked to indicate when they hear a sound, typically by pressing a button. This process is repeated for each ear separately to determine the faintest tones that can be heard.
  • Bone Conduction Testing After air conduction testing, a bone oscillator is placed on the mastoid bone behind one ear. Similar pure tone sounds are transmitted through the oscillator, allowing the audiologist to assess the patient's bone conduction hearing. The patient again indicates when they hear the sounds, which helps differentiate between types of hearing loss.
  • Results Compilation Upon completion of both air and bone conduction tests, the results are compiled and plotted on an audiogram. This graphical representation illustrates the patient's hearing thresholds across different frequencies for each ear.
  • Interpretation of Findings A written report is generated, summarizing the test results and providing an interpretation of the findings. This report is essential for further clinical evaluation and management of the patient's hearing health.

3. Post-Procedure

After the completion of pure tone audiometry, patients may receive immediate feedback regarding their hearing status. The audiologist will discuss the results and any necessary follow-up actions, which may include referrals to specialists, recommendations for hearing aids, or further diagnostic testing if indicated. Patients are advised to schedule regular hearing evaluations, especially if they have risk factors for hearing loss. Additionally, any significant findings from the audiogram will be documented in the patient's medical record for ongoing monitoring and management of their auditory health.

AB Audiology service furnished personally by an audiologist without a physician/npp order for non-acute hearing assessment unrelated to disequilibrium, or hearing aids, or examinations for the purpose of prescribing, fitting, or changing hearing aids; service may be performed once every 12 months, per beneficiary
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
GA Waiver of liability statement issued as required by payer policy, individual case
GW Service not related to the hospice patient's terminal condition
GV Attending physician not employed or paid under arrangement by the patient's hospice provider
CR Catastrophe/disaster related
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
25 Significant, separately identifiable evaluation and management service by the same physician or other qualified health care professional on the same day of the procedure or other service: it may be necessary to indicate that on the day a procedure or service identified by a cpt code was performed, the patient's condition required a significant, separately identifiable e/m service above and beyond the other service provided or beyond the usual preoperative and postoperative care associated with the procedure that was performed. a significant, separately identifiable e/m service is defined or substantiated by documentation that satisfies the relevant criteria for the respective e/m service to be reported (see evaluation and management services guidelines for instructions on determining level of e/m service). the e/m service may be prompted by the symptom or condition for which the procedure and/or service was provided. as such, different diagnoses are not required for reporting of the e/m services on the same date. this circumstance may be reported by adding modifier 25 to the appropriate level of e/m service. note: this modifier is not used to report an e/m service that resulted in a decision to perform surgery. see modifier 57 for significant, separately identifiable non-e/m services, see modifier 59.
32 Mandated services: services related to mandated consultation and/or related services (eg, third party payer, governmental, legislative or regulatory requirement) may be identified by adding modifier 32 to the basic procedure.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
