CPT (Current Procedural Terminology) codes are five-digit numbers that describe every medical service or procedure. Your doctor, hospital, and insurance company use them to communicate exactly what was done. Every line on your medical bill has a CPT code, and knowing the code lets you look up what Medicare pays for that same service.

Why do providers charge so much more than Medicare pays?

Providers set their own "chargemaster" prices, which are essentially list prices. Medicare pays a fixed rate based on the resources each service actually requires (the RVU system for procedures, or the Clinical Lab Fee Schedule for lab tests). Commercial insurers typically pay 150% to 250% of Medicare rates. Uninsured patients are often billed the full chargemaster price, which can be 2x to 30x what Medicare pays.

Can I use Medicare rates to negotiate my bill?

Yes. Medicare rates are the closest thing to a "fair price" benchmark in U.S. healthcare. When negotiating, ask the provider what they accept from Medicare for the same CPT code. Most providers will accept 150% to 200% of Medicare for cash-pay patients, which is still far less than their chargemaster price. Many hospital financial assistance policies also use a multiple of Medicare as their discount floor.

How are Medicare rates calculated?

For most procedures, Medicare uses the Resource-Based Relative Value Scale (RBRVS). Each CPT code gets three RVU components: Work (physician time and skill), Practice Expense (overhead), and Malpractice. These are multiplied by geographic adjustment factors (GPCIs) and a conversion factor ($33.4009 in 2026). Lab tests (80000-89999 range) use a separate Clinical Laboratory Fee Schedule with flat national rates.

CPT 92557

Comprehensive Hearing Test (Audiometry + Speech Recognition)

CPT 92557 is a comprehensive hearing evaluation that combines pure-tone audiometry with speech recognition testing. Providers charge an average of $119.97, while Medicare pays only $35.74 (a 3.4x markup). The critical coverage distinction: hearing tests to diagnose a medical condition are covered by Medicare, while hearing tests for the purpose of getting hearing aids are explicitly excluded by federal statute.

How the Medicare Rate Is Calculated

Medicare values every procedure using Relative Value Units (RVUs) across three components, then multiplies by a national conversion factor of $33.4009 (2026). Here is the exact math for a comprehensive hearing test:

Component	What It Covers	Office (Non-Facility)	Hospital (Facility)
Work RVU	Audiologist time and interpretation	0.60	0.60
Practice Expense RVU	Sound booth, audiometer, staff	0.30	0.30
Malpractice RVU	Professional liability insurance	0.03	0.03
Total RVU		0.93	0.93
x $33.4009	2026 conversion factor	$35.74	$35.74

Why the 3.4x markup is notable: This test uses standard equipment (audiometer, sound booth) that has been around for decades. The $120 average charge for a 20 to 30 minute test performed by a technician is high relative to the $36 that Medicare considers fair compensation. This markup reflects the market power of audiology practices, particularly those bundling hearing test costs into hearing aid sales.

Medicare Rate by State

Medicare adjusts the national rate based on your location using Geographic Practice Cost Indices (GPCIs). The same hearing test pays differently by state, ranging from about $27 in Arkansas to $34 in Alaska.

Sample State Rates (Office Setting)

State	Medicare Pays	Avg. Charge	Markup
Texas (Austin)	$29.27	$119.97	4.1x
California (Los Angeles)	$30.69	$119.97	3.9x
New York (Manhattan)	$30.95	$119.97	3.9x
Florida (Fort Lauderdale)	$29.56	$119.97	4.1x
Ohio	$27.66	$119.97	4.3x
Mississippi	$26.75	$119.97	4.5x
Arkansas	$26.60	$119.97	4.5x
Alaska	$33.95	$119.97	3.5x

Rates shown are for the non-facility (office) setting using 2026 GPCIs and the $33.4009 conversion factor. The average provider charge of $119.97 is the 2023 national average from CMS utilization data. Actual charges vary by provider.

What Insured Patients Actually Pay for a Hearing Test

Coverage for hearing tests hinges on one critical factor: why the test was ordered. A hearing test to diagnose a medical condition is usually covered. A hearing test for hearing aid fitting is often excluded. The same CPT code (92557) can be covered or denied based solely on the diagnosis code attached.

Your Situation	What You Likely Pay	How It Works
Medicare (diagnostic, covered)	$7.15	20% coinsurance of $35.74 after deductible
Medicare (hearing aid fitting, denied)	$120 (full charge)	Excluded by statute, you pay the provider's full rate
Commercial plan (copay, covered)	$20 to $50	Specialist copay for diagnostic test
High-deductible plan (not met)	$60 to $120	Full negotiated rate until deductible is met
Insurance with hearing benefit	$0 to $25	Some plans cover annual hearing tests as preventive

The diagnosis code determines coverage. If your hearing test is denied, ask your provider what diagnosis code was used. Codes for sudden hearing loss (H91.2), tinnitus (H93.1), vertigo (R42), or otalgia (H92.0) typically trigger coverage. Codes for hearing loss screening (Z13.5) or hearing aid examination (Z46.1) often trigger denial under Medicare.

Should You Use Insurance or Pay Cash for a Hearing Test?

Because hearing tests have such a high markup (3.4x), the gap between insurance pricing and cash pricing can work in your favor. Many audiology practices offer competitive cash rates to attract patients shopping for hearing aids.

When Cash-Pay Wins

Many big-box stores (Costco, Sam's Club) offer hearing tests for free or under $50 as a loss leader for hearing aid sales
Your Medicare claim would be denied because the test is for hearing aid purposes
Your high-deductible plan means you would pay the full $120 negotiated rate anyway
You only need a basic screening, not a full diagnostic evaluation

When Using Insurance Wins

You have a medical reason for the test (sudden hearing loss, dizziness, ear pain)
Your copay is under $50 and the test is covered diagnostically
You need the results in your medical record for a referral to an ENT
Your plan includes an annual hearing benefit at no cost

Free hearing test options: Costco Hearing Centers, many Miracle-Ear locations, and university audiology clinics offer free comprehensive hearing tests. These are typically the same 92557 test billed at $120 elsewhere. The trade-off: they will follow up with hearing aid sales recommendations. But the test results are valid regardless of where you get them.

Common Billing Problems with 92557

Denied because of the diagnosis code (not the test itself)

The most common billing issue with hearing tests is denial based on the diagnosis code. If your provider used a screening code (Z13.5) or hearing aid evaluation code (Z46.1), the claim may be denied even though the test is identical. Ask your provider if a medical diagnosis code (sensorineural hearing loss H90.3, sudden hearing loss H91.2, tinnitus H93.1) is clinically appropriate. Changing the diagnosis code from screening to diagnostic can flip coverage from denied to approved.

Unbundling 92557 into component codes

CPT 92557 is a bundled code that includes both pure-tone audiometry (92552) and speech audiometry (92555/92556). Some providers bill the component codes separately instead of the bundle, which can result in higher total charges. If you see both 92552 and 92555 or 92556 on your bill instead of 92557, the total should not exceed what 92557 alone would cost. Check your EOB for unbundling.

Office visit billed on top of the hearing test

If you went to an audiologist or ENT solely for a hearing test, a separate office visit code (99213/99214) may not be justified. The evaluation and interpretation of the audiogram is included in 92557. An additional E/M code is appropriate only if a separately identifiable medical evaluation was performed (for example, examining your ear for a medical condition). If the hearing test was the only service, question the extra visit charge.

Charged for test components you did not receive

CPT 92557 requires both air and bone conduction pure-tone testing plus speech recognition testing. If your test was abbreviated (only air conduction, or only pure tones without speech testing), the correct code may be 92552 (pure-tone audiometry only, approximately $20 Medicare rate) rather than the full 92557. Review your test results document to confirm all components were actually performed.

Frequently Asked Questions

How much does a hearing test cost without insurance?

A comprehensive hearing test (CPT 92557) costs $75 to $200 without insurance, with a national average charge of $119.97. However, free hearing tests are widely available at Costco Hearing Centers, many Miracle-Ear locations, and university audiology clinics. These free tests are typically used to evaluate you for hearing aids, but the audiogram results are clinically valid.

Does Medicare cover hearing tests?

Medicare covers hearing tests only when ordered to diagnose a medical condition (such as sudden hearing loss, dizziness, tinnitus, or ear pain). Hearing tests performed solely for the purpose of fitting hearing aids are excluded by federal statute. The same test can be covered or denied depending entirely on why it was ordered. If denied, check whether the diagnosis code indicates a medical condition rather than hearing aid evaluation.

Why was my hearing test denied by insurance?

Hearing tests are commonly denied when the diagnosis code indicates routine screening or hearing aid fitting rather than a medical condition. Ask your provider to review the diagnosis code. Codes for sudden hearing loss (H91.2), vertigo (R42), tinnitus (H93.1), or otalgia (H92.0) typically trigger coverage. Codes like Z13.5 (hearing screening) or Z46.1 (hearing aid fitting) often result in denial.

What is included in a comprehensive hearing test (92557)?

CPT 92557 is a bundled code that includes both pure-tone audiometry (testing which frequencies and volumes you can hear through air and bone conduction) and speech recognition testing (how well you understand spoken words at various volumes). The test takes 20 to 30 minutes and is performed in a sound-treated booth using calibrated headphones and a bone oscillator.
