Clinicians are encouraged to reference their CPT manual for correct code use and to review payer-specific policies when determining appropriate code reporting and documentation requirements for services. Many payer clinical policies will provide criteria for Medical Necessity and will also include procedure and diagnosis codes that will support medical necessity and policies for subsequent reimbursement for services. It is advisable to review payer guidelines and policies prior to billing.
Testing for Auditory Processing Disorder (APD) refers to evaluation of the central auditory system. Several tests of central auditory function comprise an auditory processing test battery. These separate tests may include but are not limited to evaluation of different auditory processing functions, such as auditory temporal processing, auditory pattern processing, binaural separation, binaural integration and auditory performance with degraded acoustic signals.
Relevant Evaluation Codes
The following CPT codes are available for reporting assessment of central auditory processing function. The CPT codes used for an APD evaluation do not require specific tests; the evaluation (encompassed by CPT codes 92620 and 92621) is time-based, which allows the audiologist to choose the appropriate number of tests to complete the battery based upon individual patient needs.
| CPT Code | Description |
| 92620 | Evaluation of central auditory function, with report; initial 60 minutes
Do not report 92620, 92621 in conjunction with 92521,92522, 92523, 92524 |
| 92621 | Evaluation of central auditory function, with report; each additional 15 minutes (List separately in addition to code for primary procedure)
Use 92621 only in conjunction with 92620 Do not report 92620, 92621 in conjunction with 92521, 92522, 92523, 92524 |
| 92571 | Filtered speech test
Report 92571, 92572, or 92576 only if administering that test individually. |
| 92572 | Staggered spondaic word test
Report 92571, 92572, or 92576 only if administering that test individually. |
| 92576 | Synthetic sentence identification test
Report 92571, 92572, or 92576 only if administering that test individually. |
Relevant Rehabilitative Codes
The following list of codes are typically only reimbursable when provided by a licensed speech-language pathologist. Audiology providers are encouraged to review payer-specific coverage policies prior to reporting the codes presented within this section.
| CPT Code | Description |
| 92507 | Treatment of speech, language, voice, communication, and/or auditory processing disorder; individual |
| 92508 | Treatment of speech, language, voice, communication, and/or auditory processing disorder; group, 2 or more individuals |
| Note: These services are typically non-covered when performed by audiologists. Reference payer-specific coverage policies to determine whether these services are non-covered and should subsequently be moved to self-pay. | |
Relevant Diagnosis Codes
The ICD code H93.25 Central auditory processing disorder is most appropriate for reporting a diagnosis of auditory processing disorder. A more complete list of ICD codes relevant to audiologic practice is available here.
