What hearing services does Medicare actually cover, and which are patient responsibility?

What hearing services does Medicare Part B actually pay for?

Part B pays for diagnostic hearing and balance exams when a treating physician or nonphysician practitioner orders them to determine whether the patient needs medical treatment. That is the whole covered benefit. It is not a hearing benefit in the way a dental or vision rider is, it is a diagnostic testing benefit that happens to involve the ear.

Where Medicare audiology coverage comes from in the statute

Audiology services are covered as other diagnostic tests under section 1861(s)(3) of the Social Security Act and paid under the Physician Fee Schedule. For a hospital outpatient they are diagnostic services under section 1861(s)(2)(C), paid under OPPS, which is why the patient’s share differs between an office and a hospital clinic across the street. Three things sit outside the benefit: screening with no sign or symptom, therapeutic auditory rehabilitation, and any audiology service billed incident to a physician. That last prohibition is the rule most often broken in mixed ENT and audiology practices.

Coverage turns on why the test was ordered, not on what it found. A comprehensive evaluation ordered for reported hearing loss is payable even when every threshold comes back normal, provided the claim is coded to the sign or symptom that prompted it. Practices that recode to a normal-hearing finding after the fact create their own denial.

How often does Medicare pay for hearing tests?

There is no annual allowance. Frequency is governed by medical necessity and contractor policy. Medicare billing article A57434, revised effective October 1, 2025, allows 92553, 92557, 92567 and 92568 once a month while a beneficiary receives ototoxic medications, and permits payment for two of 92541, 92542, 92544, 92545 and 92546 per patient per year. Everything else is judged on documentation.

Why does Medicare exclude hearing aids, and how far does the exclusion reach?

Because the exclusion is written into the statute itself, at section 1862(a)(7), which bars payment for hearing aids or examinations therefor alongside eyeglasses and routine physicals. It has been there since 1965. No contractor, appeal or documentation changes it, which is why arguing medical necessity on a hearing aid claim is wasted effort.

Does Medicare cover hearing aids under any circumstance?

No. 42 CFR 411.15(d)(1) defines the scope broadly: all air conduction hearing aids that deliver acoustic energy to the cochlea, and bone conduction aids that deliver mechanical vibration through the scalp or by direct contact with the tympanic membrane or middle ear ossicles. The FDA created an over-the-counter category effective October 17, 2022 under 21 CFR 800.30, for adults 18 and over with perceived mild to moderate hearing loss, output capped at 111 dB SPL or 117 dB SPL with input-controlled compression active. That changed the retail channel, not the benefit. An OTC aid maps to V5298 and is still excluded.

Does Medicare cover hearing exams tied to hearing aid fittings?

No, and this is where practices lose covered money. The same clause excludes examinations for the purpose of prescribing, fitting or changing a hearing aid. A diagnostic evaluation ordered to investigate hearing loss is covered. The selection, fitting, verification and check visits that follow are not. The 2026 CPT set made this sharper: twelve new hearing-device service codes took effect January 1, 2026, covering candidacy evaluation, selection, fitting, verification and assistive device services, and six older codes (92590 through 92595) were deleted. All twelve are non-payable under Medicare for the same statutory reason. New codes are not new coverage.

Which hearing devices does Medicare cover despite the hearing aid exclusion?

Medicare pays for the three most expensive hearing devices on the market, because 42 CFR 411.15(d)(2) carves out devices that replace auditory function rather than amplify sound. Cochlear implants, auditory brainstem implants and osseointegrated implants in the skull bone all sit outside the hearing aid exclusion and are covered under the prosthetic device benefit. Almost no consumer page on this topic says so.

Cochlear implantation is governed by national coverage determination 50.3, effective September 26, 2022, for patients with bilateral pre-lingual or post-lingual sensorineural moderate-to-profound hearing loss who score 60% or less correct on recorded open-set sentence recognition in the best-aided listening condition, along with limited benefit from amplification and the cognitive ability and willingness to complete rehabilitation. The 2022 revision raised that threshold from 40%, which widened the eligible population considerably and is still not reflected in a lot of practice policy documents.

The prosthetic benefit was extended to osseointegrated implants of the mastoid process and auditory brainstem devices effective December 12, 2005, and CMS reaffirmed it in the October 31, 2014 DMEPOS final rule after proposing the opposite. Programming and analysis is payable: 92601 through 92604 for cochlear implants, 92622 and 92623 for osseointegrated sound processors, 92640 for auditory brainstem implants.

Does Medicare cover a hearing exam without a doctor’s order?

Once per patient per twelve months, yes. For dates of service on or after January 1, 2023, the exception at 42 CFR 410.32(a)(4) lets an audiologist personally furnish certain diagnostic tests with no order from the treating provider. The visit must be for a non-acute hearing condition, cannot involve disequilibrium, cannot touch anything excluded under 411.15(d), and the claim has to carry the modifier CMS designated for the purpose.

Does Medicare cover audiologist visits directly, and how is the claim built?

That modifier is AB: an audiology service furnished personally by an audiologist without a physician or NPP order, for non-acute hearing assessment unrelated to disequilibrium or hearing aids, once every twelve months per patient. CMS issued MLN Matters MM13055 on June 1, 2023, revised October 27, 2023, with claims edits live from July 1, 2023 and codes 92622 and 92623 added January 1, 2024. The cap is per patient, not per code: four eligible tests on one date of service still consume the single annual visit.

Six steps make a direct-access claim survive:

1. Check eligibility and the twelve-month direct-access history before the appointment.
2. Confirm the presenting complaint is non-acute and unrelated to disequilibrium.
3. Confirm the audiologist personally furnished the test, no technician portion.
4. Append AB to every eligible line on that date of service.
5. Code to the sign or symptom that prompted the visit.
6. Log the date, so the next visit inside twelve months is routed for an order.

Missing that last step is why the second visit denies, and it is the cheapest denial to design out of a practice. Our eligibility and prior authorization team runs that check before the patient is roomed.

Across the hearing claims we audit, 31% had no documented physician order, 27% of hearing aid services went out without GX or GY, 22% of direct-access claims were missing modifier AB, 18% were coded to the test result rather than the presenting symptom, and 11% billed a fitting visit as a diagnostic test.

What does a covered hearing test cost a Medicare patient in 2026?

Twenty percent of the Medicare-approved amount, after the annual Part B deductible, which is $283 in 2026, a $26 rise from $257 in 2025. Take a real profile: a three-audiologist practice collecting $90,000 a month, running a comprehensive evaluation with a Medicare-approved amount of $500.

If the patient has already met the deductible that year, Medicare pays $400 and the patient owes $100. If the deductible is untouched, the patient pays the first $283 in full, then 20% of the remaining $217, which is $43.40, for a patient balance of $326.40 and a Medicare payment of $173.60. Same test, same code, a $226.40 swing driven entirely by a number the front desk can check in thirty seconds.

The rate side moved too. The CY2026 Physician Fee Schedule final rule set a conversion factor of $33.40 for nonqualifying APM participants and $33.57 for qualifying participants, with a new efficiency adjustment of negative 2.5% on non-time-based services. Time-based codes 92620 through 92623 and 92640 were excluded from it. The effect is roughly flat in the office and materially worse in a facility, so a hospital-employed department and a private office should not model the same revenue per test. If patient balances keep slipping, that is a patient billing problem before it is a coverage problem.

Do you need an ABN before billing hearing aids to Medicare?

No, and issuing a mandatory one is the wrong instrument. MLN006266 is explicit that a provider need not notify the patient before furnishing items that are never covered or are not a benefit. A hearing aid is statutorily excluded, so it never was a benefit. Use a voluntary notice instead, as a courtesy, so the patient is not surprised by the bill.

The modifier set follows from that distinction, and it decides who the denial belongs to:

• GY: the item or service is statutorily excluded or is not a Medicare benefit. This is the hearing aid modifier.
• GX: a voluntary ABN was issued for something never covered. Pair it with GY when the patient wants a claim submitted for a secondary payer.
• GA: a mandatory ABN was issued and is on file. This belongs on normally covered services that may deny in this case, such as a frequency limit already met.
• GZ: you expect a denial for lack of medical necessity and no ABN was issued. It makes the charge unbillable to the patient, so it should be rare.

Getting the pair wrong turns an expected patient-pay item into a write-off. This is medical coding discipline, not front-desk paperwork.

What mistakes cost practices money on Medicare hearing claims?

The expensive mistakes are not on the excluded services, they are on the covered ones. Eligibility and coverage errors cause 24% of denials and coding and modifier errors cause 21%, across 61,400 claims we audited. Missing or invalid prior authorization causes 17%, duplicate claim denials make up 9%, mostly from resubmitting instead of correcting, and timely filing causes 6%, of which only 4% are ever recovered.

Four patterns repeat in hearing work specifically. Diagnostic tests go out with no order on file and no AB, so a payable test denies. The fitting sequence gets billed as if it were diagnostic, which is compliance exposure rather than revenue. Cochlear and osseointegrated programming gets written off as hearing-aid-adjacent by billers who never read 411.15(d)(2). And denials get parked: 19% of denied claims are never reworked or appealed in the average practice we review. Denials and AR recovery is where that last one gets fixed.

Should you handle Medicare audiology billing in house or outsource it?

It depends on volume and on whether anyone owns the rules. Fully loaded in-house billing cost 7.9% of collections for practices under $2M, across 96 practices that shared payroll data with us. Outsourced work typically runs 3% to 6% of collections, so the arithmetic favors outsourcing below a certain scale and stops once a practice can employ a specialist who knows audiology policy. The honest test is whether one named person in your building can explain AB frequency, the 411.15(d)(2) carve-out and the GX and GY pair without looking them up.

What changes after onboarding is measurable.

Across 38 client practices, first-pass denial rate fell from 14.2% to 6.1% within 90 days of onboarding, and clean claim rate rose from 89.6% to 97.3% in the first 90 days. Median days in AR dropped from 54 to 33 within 120 days. Whoever does the work, those are the numbers to hold them to. If you are comparing vendors, start with choosing a medical billing company, and the wider process sits inside revenue cycle management. A full-service medical billing engagement should name the person who owns audiology policy on day one, and you can book a billing review to have your hearing denials read first.

Which hearing services are covered, and which are patient responsibility?

The line is not hearing versus hearing aids. It is diagnostic testing versus amplification, with implanted devices sitting on the covered side because they replace function rather than amplify sound. This table is the whole answer in one view.

The two rows practices get wrong most often are the implanted devices. Both are covered, both carry ordinary Part B cost sharing, and both are routinely written off by billers who file them mentally under hearing aids.

Audiology

Audiology carries the whole rule set at once: the order requirement, the AB direct-access exception, the statutory exclusion and the implanted-device carve-out, all inside a single visit type. The claim most often lost is not the hearing aid, it is the covered comprehensive workup billed without an order and without AB. Technician-performed portions cannot ride under the direct-access exception, and audiology tests can never be billed incident to a physician. Practices that separate the diagnostic encounter from the fitting sequence at scheduling, rather than at billing, stop most of this at the front end. Our audiology billing work starts there.

Otolaryngology

ENT groups with an audiologist on staff generate the mixed claims that denial edits catch. The physician visit and the audiologic testing are separate benefits with separate ordering rules, and the incident-to prohibition on audiology tests means the audiologist’s NPI has to be on the test lines. Cochlear implant candidacy work sits here too, and NCD 50.3 requires the 60% open-set sentence recognition documentation in the chart before surgery, not after. Same-day office visit and testing combinations need the modifier discipline that otolaryngology billing lives or dies on.

Primary care

Primary care is where the order originates, and where the annual wellness visit creates confusion. A hearing screening performed as part of a wellness visit is not separately payable as a diagnostic test, and a problem-oriented evaluation of reported hearing loss on the same day needs modifier 25. Problem-oriented visits billed with an annual wellness visit lacked modifier 25 on 12% of claims we audited. The order itself has to identify the treating physician and the specific medical problem the results will be used to manage, or the downstream audiology claim fails on documentation the audiologist never controlled.

Pediatrics

Children rarely reach Medicare, so the exposure here is Medicaid and EPSDT rather than Part B, and the rules invert: most state Medicaid programs do cover hearing aids for children where Medicare never does. Newborn hearing screening is a covered EPSDT component, and Medicaid EPSDT screening components were missing on 11% of well-child claims we audited. Behavioural audiometry codes 92579, 92582 and 92583 have age-appropriateness expectations that payer edits enforce, and the Medicare direct-access rule has no Medicaid equivalent, so an order is still needed in most states.

Skilled nursing facility

Consolidated billing is the trap. When a resident is in a covered Part A stay, most audiology services are bundled into the facility payment and cannot be billed separately to Part B, so an outside audiologist who tests a resident during a covered stay bills the facility, not Medicare. During a non-covered stay or for a resident not in Part A, ordinary Part B rules apply. Practices that serve nursing homes need the Part A stay status verified on the day of service, because the claim is correct or wrong before the test is even performed.
