Official Description

Assessment of tinnitus (includes pitch, loudness matching, and masking)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Tinnitus is defined as the perception of sound that originates from within the inner ear or head, rather than from an external source. This condition is often experienced as subjective tinnitus, where the sound is only audible to the individual affected. In rare cases, it can manifest as objective tinnitus, which can also be heard by a healthcare provider. Patients typically describe the sounds associated with tinnitus in various ways, including hissing, buzzing, ringing, squealing, whining, clicking, or popping. The nature of tinnitus can vary, with some individuals experiencing it continuously while others may have intermittent episodes. The assessment of tinnitus involves a comprehensive evaluation that includes pitch matching, loudness matching, and determining the minimum masking level (MML) of the tinnitus. During this assessment, earphones are utilized to deliver auditory stimuli, and an audiometer is employed to display and record the findings. Each ear is tested separately to ensure accurate results. The pitch matching process requires the patient to identify a sound stimulus that closely matches the pitch of their tinnitus. Similarly, loudness matching involves the patient identifying the intensity of a sound that corresponds to the loudness of their tinnitus. The masking evaluation aims to find the lowest level of sound stimulus that effectively masks the tinnitus, making it inaudible to the patient. Following the assessment, the results are interpreted, and a detailed written report of the findings is provided to the healthcare provider for further evaluation and management.

1. Indications

The assessment of tinnitus is indicated for patients experiencing persistent or bothersome tinnitus symptoms. The following conditions may warrant this evaluation:

  • Subjective Tinnitus Patients who report hearing sounds such as ringing, buzzing, or hissing that are not present in the external environment.
  • Objective Tinnitus Cases where the tinnitus can also be heard by a healthcare provider during examination.
  • Intermittent Tinnitus Individuals who experience episodes of tinnitus that come and go, affecting their quality of life.
  • Continuous Tinnitus Patients who have a constant perception of sound that may interfere with daily activities or sleep.

2. Procedure

The procedure for assessing tinnitus involves several key steps to ensure a comprehensive evaluation of the patient's condition. Each step is designed to gather specific information about the tinnitus experienced by the patient.

  • Pitch Matching In this step, auditory stimuli are delivered through earphones to the patient. The patient is instructed to listen carefully and match the pitch of the sound they hear through the earphones to the pitch of their tinnitus. This process helps to identify the frequency of the tinnitus, which is crucial for understanding its characteristics.
  • Loudness Matching Following pitch matching, the loudness matching procedure is conducted. Similar to the previous step, various sound stimuli of differing intensities are presented to the patient through the earphones. The patient must identify the loudness level of the stimulus that corresponds to the loudness of their tinnitus. This step is essential for quantifying the intensity of the tinnitus.
  • Masking Evaluation The final step involves a masking evaluation, where sound stimuli are used to mask the tinnitus. The patient is asked to identify the lowest level of sound that effectively makes the tinnitus inaudible. This assessment provides valuable information about the minimum masking level (MML) required to alleviate the perception of tinnitus.

3. Post-Procedure

After the assessment of tinnitus is completed, the results are carefully interpreted by the healthcare provider. A detailed written report of the findings is generated, which includes the outcomes of the pitch matching, loudness matching, and masking evaluation. This report serves as a critical tool for the provider to understand the patient's tinnitus profile and to develop an appropriate management plan. Patients may be advised on potential treatment options or further evaluations based on the results of the assessment. Follow-up appointments may be scheduled to discuss the findings and any necessary interventions.

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.
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
GA Waiver of liability statement issued as required by payer policy, individual case
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
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).
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.
95 Synchronous telemedicine service rendered via a real-time interactive audio and video telecommunications system: synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located at a distant site from the physician or other qualified health care professional. the totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that would be sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction. modifier 95 may only be appended to the services listed in appendix p. appendix p is the list of cpt codes for services that are typically performed face-to-face, but may be rendered via a real-time (synchronous) interactive audio and video telecommunications system.
CR Catastrophe/disaster related
GW Service not related to the hospice patient's terminal condition
GX Notice of liability issued, voluntary under payer policy
GY Item or service statutorily excluded, does not meet the definition of any medicare benefit or, for non-medicare insurers, is not a contract benefit
