Acoustic reflex threshold testing, identified by CPT® Code 92568, is a specialized auditory assessment that evaluates the response of the stapedius muscle and tensor tympani to loud sounds. This testing is crucial for understanding the functionality of the middle ear and the auditory pathway. When a loud sound is presented, the stapedius muscle contracts, which in turn causes the stapes bone to move. This movement is a protective mechanism that helps to reduce the transmission of loud sounds to the inner ear, thereby preventing potential damage to the auditory structures. The acoustic reflex threshold specifically measures the minimum intensity of sound that can trigger this reflex contraction of the stapedius muscle. The testing is typically conducted using the same equipment employed for tympanometry, where a loud sound is emitted, prompting the stapedius muscle to contract. This contraction alters the immittance of the middle ear, which is then recorded as a deflection on the testing device. The physician is responsible for reviewing and interpreting these results to assess the integrity of the auditory system and to identify any potential abnormalities in the reflex pathway.

Acoustic reflex threshold testing is indicated for various clinical scenarios where assessment of the auditory system is necessary. The following conditions may warrant this testing:
The procedure for acoustic reflex threshold testing involves several key steps to ensure accurate measurement and interpretation of results. The following outlines the procedural steps:
Post-procedure care for acoustic reflex threshold testing is generally minimal, as the test is non-invasive and does not require any recovery time. Patients may resume their normal activities immediately following the test. The audiologist or physician will discuss the results with the patient, providing insights into the findings and any further steps that may be necessary based on the outcomes. If any abnormalities are detected, additional diagnostic testing or referrals to specialists may be recommended to address underlying issues.

| 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. | 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 | AG | Primary physician | CC | Procedure code change (use 'cc' when the procedure code submitted was changed either for administrative reasons or because an incorrect code was filed) | GA | Waiver of liability statement issued as required by payer policy, individual case | GV | Attending physician not employed or paid under arrangement by the patient's hospice provider | GW | Service not related to the hospice patient's terminal condition | 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 | GZ | Item or service expected to be denied as not reasonable and necessary | XE | Separate encounter, a service that is distinct because it occurred during a separate encounter | XS | Separate structure, a service that is distinct because it was performed on a separate organ/structure | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service |
