Audiology billing requires precise documentation to separate covered diagnostic services from non-covered routine hearing and hearing aid dispensing—a distinction that directly impacts revenue and compliance. VeriMedix delivers specialized audiology RCM that maximizes covered service reimbursement while keeping your practice compliant with Medicare and commercial payer rules.
Audiology billing is uniquely shaped by a fundamental Medicare coverage constraint: hearing aids and hearing aid dispensing are expressly excluded from Medicare Part B coverage by statute. This means that audiologists must carefully separate their medically necessary diagnostic and rehabilitative services—which are covered—from hearing aid fittings, dispensing, and routine hearing checks, which are not. Covered Medicare audiology services include comprehensive diagnostic audiological evaluations (92557), audiometric testing (92551–92553, 92562–92563), speech audiometry (92555–92556), tympanometry (92567), stapedial reflex testing (92568), and auditory brainstem response testing (92585–92586). When an audiologist performs these services under an order from a physician (or an applicable practitioner) for a patient with symptoms or a condition requiring evaluation—hearing loss, tinnitus, dizziness, balance disorders, or post-otologic surgery evaluation—the services are covered as a diagnostic benefit under Medicare Part B.
The billing infrastructure for audiology differs from most medical specialties in that audiologists bill under their own NPI but typically must meet Medicare's physician-order requirement for covered audiometric testing. Comprehensive audiological evaluation (92557) includes pure tone air and bone conduction audiometry (covered by 92553 alone if performed in isolation) plus speech recognition testing—it is a bundled code that combines what would otherwise be separately billed 92553 + 92556. When only one component is performed, the component code (92553 for pure tone air conduction audiometry or 92555 for speech recognition threshold) should be billed rather than 92557. Acoustic immittance testing—tympanometry (92567) and stapedial reflex (92568)—is separately billable from 92557 when performed. Auditory brainstem response (ABR) testing (92585 for comprehensive, 92586 for limited) is separately billable and is covered for diagnosis of neural hearing loss, auditory neuropathy spectrum disorder, and neonatal hearing screening follow-up.
Tinnitus evaluation and management is a growing clinical area with specific coding requirements. CPT 92625 covers assessment of tinnitus (includes pitch, loudness, masking, and residual inhibition) and is separately billable when performed as part of a diagnostic workup. Vestibular/balance testing—videonystagmography (VNG: 92537 for caloric testing with recording, 92540 for basic vestibular examination, 92541–92544 for individual components, 92548 for computerized dynamic posturography)—is a significant revenue category for audiologists in ENT-adjacent or neurotology practices. Cochlear implant-related services generate high revenue: candidacy evaluation, programming/mapping (92601–92604), and follow-up auditory rehabilitation are all separately billable. Hearing aid dispensing and fitting codes (V5010–V5299 HCPCS) are used for non-Medicare payers that cover hearing aids, including some Medicaid programs and commercial plans that include hearing benefits.
Below are commonly billed codes our certified coders manage for audiology practices. Always confirm payer-specific coverage and current code values.
| Code | Description | Billing note |
|---|---|---|
92557 | Comprehensive audiometry threshold evaluation and speech recognition (92553 and 92556 combined) | Most common diagnostic audiology code; includes air/bone conduction pure tone audiometry AND speech recognition; bill separately if only one component performed |
92553 | Pure tone audiometry (threshold); air and bone | Use when only pure tone air and bone conduction testing is performed without speech recognition testing; do not bill with 92557 |
92567 | Tympanometry (impedance testing) | Separately billable from 92557; tests middle ear pressure and mobility; document type of tympanogram and results |
92568 | Acoustic reflex testing, threshold | Stapedial reflex threshold testing; separately billable from 92557 and 92567; document ipsilateral and contralateral reflexes |
92585 | Auditory evoked potentials for evoked response audiometry and/or testing of the central nervous system; comprehensive | ABR testing; used for neural hearing loss, auditory neuropathy, neonatal threshold estimation; requires physician order; -26 in facility |
92625 | Assessment of tinnitus (includes pitch, loudness matching, masking for residual inhibition) | Tinnitus evaluation; separately billable; document all components tested and results; payer coverage varies |
92537 | Caloric vestibular test with recording, bilateral; bithermal (i.e., 4 or more irrigations) | VNG caloric component; used for peripheral vestibular disorder evaluation; part of comprehensive vestibular test battery |
92601 | Diagnostic analysis of cochlear implant; age 7 years or older | Post-implant programming and audiological assessment; 92602 for 7+ (subsequent), 92603/92604 for under 7 (initial/subsequent) |
V5008 | Hearing screening, Medicare excluded; used for non-Medicare payers with hearing benefit | HCPCS V-code for routine hearing screening; non-covered by Medicare; used with Medicaid and commercial vision/hearing plans |
Our standard operating procedures for audiology revenue cycle management — the step-by-step workflow we follow on every claim:
These are the issues we see most often in audiology billing — and exactly how we resolve them:
Hearing aids, hearing aid fittings, hearing aid dispensing, and hearing aid repairs are explicitly excluded from Medicare Part B by statute. Billing these services to Medicare causes claim denial and, if systematic, creates fraud and abuse liability. Fix: Configure the billing system to route all hearing aid codes (V5010–V5299, 92592–92593 hearing aid check codes) away from Medicare; train all front desk and billing staff on the statutory exclusion; issue clear patient communication at intake about self-pay hearing aid costs.
Medicare requires that covered diagnostic audiology services be ordered by a physician or applicable non-physician practitioner. Claims submitted without a documented order on file are denied or subject to recoupment. Fix: Implement a policy that no Medicare audiology claim is submitted without a confirmed physician referral or order in the medical record; retain the order documentation in the chart; include referring provider NPI on the claim.
CPT 92557 is a bundled code covering both pure tone audiometry AND speech recognition. Billing 92557 when only a pure tone test was performed overstates the service. Fix: Confirm at charge entry that both components (92553 and 92556 equivalent) were performed before selecting 92557; use component codes when only part of the evaluation was completed.
Billing 92540 (basic vestibular evaluation) when individual caloric and positional tests were actually performed forfeits revenue—the individual components (92537–92544) may reimburse more than the bundle. Fix: Audit vestibular test charge capture against clinical test records; build a charge capture template that maps each VNG test component to its specific CPT code; compare bundled vs. unbundled reimbursement by payer.
Using 92601/92602 (age 7 and older) codes for patients under age 7, or 92603/92604 (under age 7) for older patients, results in claim denial. Fix: Build an age-check rule in the billing system that validates the cochlear implant code against the patient's date of birth before claim submission; update the rule on the patient's 7th birthday.
Verimedix works inside the systems audiology practices already use, including:
Yes, Medicare Part B covers diagnostic audiological examinations when ordered by a physician (MD or DO) or applicable practitioner (NP, PA, CNS) for the purpose of assessing a covered condition—hearing loss, tinnitus, vertigo, dizziness, or otologic post-surgical evaluation. The services must be medically necessary, not routine hearing screenings. The audiologist bills under their own NPI with an appropriate taxonomy code; the physician order must be in the record.
Yes. CPT 92567 (tympanometry) and 92568 (acoustic reflex) are separately billable from 92557 when performed and documented. Append modifier -59 if NCCI edits apply to the combination. Document all test components and results in a signed report. Most Medicare and commercial payers cover these as separate diagnostic tests.
Newborn hearing screen failures requiring diagnostic confirmation are billed with 92585 (comprehensive ABR) or 92586 (limited ABR). These require a physician referral and documentation of the failed newborn screen. ICD-10 Z13.5 (encounter for screening for eye and ear disorders) or H91.90 (unspecified hearing loss, unspecified ear) may apply. Some state Medicaid programs have specific early hearing detection program billing rules—verify state-specific requirements.
CPT 92625 is a covered service under Medicare Part B when performed as part of a diagnostic workup for a patient with tinnitus (ICD-10 H93.1x series). It requires a physician order and documentation of all tinnitus assessment components (pitch matching, loudness matching, masking, residual inhibition). Standalone tinnitus counseling or sound therapy may not be separately covered; verify with specific payer policies.
APD evaluations use a combination of codes depending on the tests performed: 92620 (evaluation of central auditory processing, initial 60 minutes) and 92621 (each additional 15 minutes). These are separately billable from 92557. Documentation must specify the clinical indication (ICD-10 H93.25 central auditory processing disorder) and detail the tests performed. Payer coverage varies significantly—many commercial plans cover APD evaluation; Medicare coverage depends on the clinical presentation and referral source.
Traditional Medicare Part B excludes hearing aids by statute. However, Medicare Advantage (Part C) plans are permitted—and increasingly required—to include supplemental hearing benefits including hearing aids, fitting, and follow-up services. Audiologists who are in-network with Medicare Advantage plans can bill for hearing aid dispensing under those plans using HCPCS V-codes. Always verify the patient's specific Medicare Advantage plan benefits before providing hearing aid services.
