Evoked otoacoustic emissions (OAE) screening is a diagnostic procedure used to assess the functional status of the cochlea, specifically focusing on the health of the hair cells within this structure. The cochlea, a spiral-shaped organ in the inner ear, not only receives sound but also generates low-intensity sounds known as otoacoustic emissions. These emissions are thought to result from the movement of the outer hair cells in the cochlea, which expand and contract in response to auditory stimuli. The OAE tests are particularly beneficial for identifying hearing loss, especially in populations such as neonates, infants, or individuals with developmental disabilities, as they do not require any behavioral response from the patient. The screening can be conducted using two primary methods: distortion product evoked otoacoustic emissions (DPEOAEs) and transient evoked otoacoustic emissions (TEOAEs). In DPEOAE testing, two simultaneous tones of different frequencies are used to elicit emissions, while TEOAE testing employs brief acoustic stimuli, such as clicks or tone bursts. During the procedure, a microphone probe is placed in the external ear canal, and the emitted otoacoustic emissions are recorded and analyzed by specialized software. The results of the screening are then reviewed by a physician to determine if further testing is necessary.

Evoked otoacoustic emissions screening is indicated for the following conditions:
The procedure for evoked otoacoustic emissions screening involves several key steps to ensure accurate measurement and analysis of cochlear function.
After the evoked otoacoustic emissions screening, there are typically no specific post-procedure care requirements, as the test is non-invasive and does not involve any recovery time. Patients can resume their normal activities immediately following the procedure. The physician will discuss the results with the patient or guardians, providing guidance on any necessary follow-up actions or additional testing if the screening indicates potential hearing issues.

| 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. | 26 | Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number. | 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). | 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 | 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 | X1 | Continuous/broad services: for reporting services by clinicians, who provide the principal care for a patient, with no planned endpoint of the relationship; services in this category represent comprehensive care, dealing with the entire scope of patient problems, either directly or in a care coordination role; reporting clinician service examples include, but are not limited to: primary care, and clinicians providing comprehensive care to patients in addition to specialty care | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service |
