Official Description

Distortion product evoked otoacoustic emissions; limited evaluation (to confirm the presence or absence of hearing disorder, 3-6 frequencies) or transient evoked otoacoustic emissions, with interpretation and report

Common Language Description

Otoacoustic emission (OAE) tests are specialized auditory assessments designed to evaluate the functional status of the cochlea, particularly focusing on the health and performance of the hair cells within this critical structure of the inner ear. These tests are essential for identifying potential hearing loss, especially in populations such as neonates, infants, or individuals with developmental disabilities, where traditional behavioral responses to sound may not be feasible. The cochlea, in addition to its role in hearing, generates low-intensity sounds known as otoacoustic emissions, which are thought to result from the dynamic movements of the outer hair cells as they respond to auditory stimuli. The CPT® Code 92587 specifically refers to a limited evaluation of these emissions, utilizing either distortion product evoked otoacoustic emissions (DPEOAEs) or transient evoked otoacoustic emissions (TEOAEs) to ascertain the presence or absence of a hearing disorder. This evaluation is characterized by the application of a stimulus through a low-noise microphone that captures the otoacoustic emissions produced by the cochlea. In the case of DPEOAEs, the assessment involves recording emissions in response to multiple tones across a range of frequencies and intensities, specifically focusing on 3-6 frequencies to confirm cochlear function. Alternatively, TEOAEs are recorded in response to brief acoustic stimuli, such as clicks or tone bursts, providing another method to evaluate cochlear health. The procedure requires the placement of a microphone probe in the external ear canal, and the test is conducted on both ears to ensure comprehensive assessment. Following the evaluation, a physician interprets the results and generates a detailed report outlining the findings, which is crucial for further clinical decision-making.

1. Indications

The procedure described by CPT® Code 92587 is indicated for the following conditions:

  • Hearing Disorder Confirmation This evaluation is performed to confirm the presence or absence of a hearing disorder, particularly in individuals who may be at risk for hearing loss.
  • Screening for Hearing Loss OAE tests are valuable for screening neonates, infants, and individuals with developmental disabilities, as they do not require a behavioral response to sound.

2. Procedure

The procedure for CPT® Code 92587 involves several key steps to ensure accurate evaluation of otoacoustic emissions:

  • Step 1: Preparation The patient is positioned comfortably, and a microphone probe is prepared for insertion into the external ear canal of the ear being tested. This probe is essential for both delivering the acoustic stimulus and recording the resulting otoacoustic emissions.
  • Step 2: Stimulus Application A stimulus is applied through the microphone probe. For a limited evaluation using distortion product evoked otoacoustic emissions (DPEOAEs), multiple tones are presented at varying frequencies and intensities. This step is crucial for eliciting the cochlear response necessary for assessment.
  • Step 3: Emission Recording The microphone records the otoacoustic emissions produced by the cochlea in response to the acoustic stimuli. The evaluation specifically requires the use of 3-6 frequencies to confirm cochlear function effectively.
  • Step 4: Contralateral Testing The procedure is repeated on the contralateral ear to ensure a comprehensive assessment of cochlear function across both ears.
  • Step 5: Interpretation and Reporting After the recordings are completed, the physician reviews the test results. A written report is generated, detailing the findings and providing essential information for further clinical evaluation and management.

3. Post-Procedure

Post-procedure care for CPT® Code 92587 typically involves the physician discussing the results with the patient or their guardians. The findings from the otoacoustic emissions test can guide further diagnostic evaluations or interventions if a hearing disorder is confirmed. There are generally no specific recovery requirements following the test, as it is non-invasive and does not involve any surgical procedures. Patients can resume normal activities immediately after the evaluation.

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.
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
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
TC Technical component; under certain circumstances, a charge may be made for the technical component alone; under those circumstances the technical component charge is identified by adding modifier 'tc' to the usual procedure number; technical component charges are institutional charges and not billed separately by physicians; however, portable x-ray suppliers only bill for technical component and should utilize modifier tc; the charge data from portable x-ray suppliers will then be used to build customary and prevailing profiles
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.
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).
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).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
