Newborn Hearing Test Billing: Disputes and Coverage Explained

You just brought your newborn home, and now there's a bill in the mailbox — one that may include charges for a hearing screening you assumed was routine and covered. Newborn hearing tests are among the most commonly miscoded and overbilled procedures in maternity billing, partly because they involve separate providers, separate billing systems, and a patchwork of state mandates that insurers and hospitals frequently misapply. Before you pay anything, read this.

Why Are Newborn Hearing Test Bills So Prone to Errors?

The newborn hearing screening — formally called an otoacoustic emissions (OAE) test or automated auditory brainstem response (AABR) test — is typically performed before hospital discharge. It sounds simple. But the billing for it is anything but.

Several factors make this charge especially vulnerable to errors and overcharges:

• Separate provider billing. In many hospitals, the hearing screening is administered by an audiologist or a contracted newborn screening company — not the hospital's own staff. Patients commonly report receiving two separate bills: one from the hospital's facility charge and one from the third-party provider. This creates a high risk of duplicate billing.
• Bundling confusion. Routine newborn care during the birth admission is often billed under a global newborn care code (such as CPT 99460 or 99462). The hearing test may already be included in that bundled charge — yet billing records have shown it also appearing as a separate line item, effectively billing twice for the same service.
• Incorrect CPT codes. The hearing screening should typically be billed under CPT 92587 (OAE, limited) or CPT 92588 (OAE, comprehensive). Billing auditors and patient advocates frequently cite error rates in complex hospital bills as high as 80%, though estimates vary — and miscoded hearing tests are a documented part of that pattern.
• Mandatory coverage laws are inconsistently applied. All 50 states have laws requiring newborn hearing screenings as part of Early Hearing Detection and Intervention (EHDI) programs, and the Affordable Care Act requires most insurance plans to cover preventive screenings without cost-sharing when billed correctly. When the wrong code is used, the claim may not trigger the preventive care benefit — and the cost gets pushed to you.
• Failed screening follow-ups billed incorrectly. If your baby didn't pass the initial screen and required a repeat test before discharge, some patients have experienced that billed as a diagnostic procedure rather than a preventive screening, which changes the cost-sharing calculation entirely.

What Specific Charges Should You Look for on the Bill?

Request an itemized bill immediately. Under state laws and CMS Conditions of Participation, you generally have the right to a complete line-item statement of every charge. Call the billing department and ask for it in writing. Then look for these specific red flags:

• A facility fee AND a separate professional fee for the same hearing test. These should not both land on your balance without a clear explanation of what each covers.
• CPT 92587 or 92588 appearing as a separate charge when you were also billed global newborn care codes (99460, 99461, or 99462). Ask the billing department directly whether the hearing screen is included in the global code already billed.
• A diagnostic code (ICD-10 Z13.5 is used for hearing screening) appearing as a treatment code. If the diagnosis code suggests a problem rather than a routine screen, the claim may have been miscoded.
• Charges for supplies or equipment associated with the hearing test listed separately (e.g., probe tips, disposable ear inserts) — these are typically included in the procedure cost.
• A repeat screening billed as a diagnostic audiology evaluation rather than a second preventive screening, particularly if your insurance processes the two differently.

How Do You Dispute a Newborn Hearing Test Charge Step by Step?

1. Request your itemized bill. Call the hospital billing department and ask for a complete itemized bill with CPT codes, diagnosis codes, and dates of service. Ask for this in writing and keep a record of when you called and who you spoke with.
2. Request your medical records. You can request your newborn's medical records at any time. The provider must respond within 30 days (with a possible 30-day extension). Look for the nursing notes documenting when the hearing screen was performed, who performed it, and whether a second screen was done.
3. Pull your Explanation of Benefits (EOB). Your EOB from your insurer will show exactly how the claim was submitted — including the CPT code, whether it was processed as preventive or diagnostic, and what your plan paid versus what it denied. Compare this line by line to your itemized hospital bill.
4. Identify the discrepancy in writing. Write down every specific mismatch you find: duplicate charges, code mismatches, or charges that appear to be bundled but were billed separately.
5. Call the hospital billing department. Use the script below. Take notes on every call including the date, the representative's name, and what was said.
6. Submit a formal written dispute. Follow up every phone call with a written dispute letter sent by certified mail. Include copies (not originals) of your itemized bill, EOB, and the specific discrepancy you are disputing.
7. Follow up with your insurer if the issue is a coding error. If the hospital used the wrong CPT code and your insurer denied or underpaid the claim as a result, call your insurer and ask them to request a corrected claim from the hospital. You have the right to appeal an insurer's coverage decision.

What Should You Say When You Call the Hospital Billing Department?

Keep your tone calm and specific. Vague complaints are easy to dismiss. Specific questions about codes are harder to brush off.

"I'm calling to review the charges on my newborn's bill from [date of service]. I've received the itemized bill and I have a few questions about specific line items. I see a charge for CPT [code] on [date]. I also see a charge for global newborn care under [code]. Can you confirm whether the hearing screening is included in the global newborn care charge or whether it was billed separately? If it was billed separately, can you tell me the name of the provider who billed it and whether a separate claim was also submitted by an outside audiology provider?"

If you suspect a duplicate charge, say so directly:

"It appears that the newborn hearing screening may have been billed twice — once as part of the facility charge and once as a separate professional fee. I'd like to request a billing review to confirm this was not a duplicate charge before I make any payment."

Ask to speak with a billing supervisor or a patient financial services specialist if the front-line representative cannot answer coding questions.

What Documentation Should You Gather Before Disputing?

• The itemized hospital bill with all CPT and ICD-10 codes
• Your Explanation of Benefits from your insurer
• Your newborn's discharge summary and any hearing screening results given at the hospital
• Any bills received from third-party providers (audiology companies, newborn screening services)
• Your insurance policy's Summary of Benefits and Coverage, specifically the preventive care section
• Notes from every phone call (date, time, representative name, what was discussed)
• Copies of all written correspondence, sent via certified mail

When Should You Escalate Beyond the Hospital Billing Department?

Most billing errors can be resolved by working directly with the hospital and your insurer. But escalation is appropriate in these situations:

• Your insurer denied coverage for a preventive screening. File a formal internal appeal with your insurer. If the internal appeal fails, you generally have the right to an external independent review under the ACA. Your EOB will include instructions for how to appeal.
• The hospital refuses to correct a documented coding error. File a complaint with your state insurance commissioner and your state's hospital licensing agency. You can also file a complaint with the Centers for Medicare & Medicaid Services (CMS).
• The balance has been sent to a third-party debt collection agency. At that point, the Fair Debt Collection Practices Act (FDCPA) applies to the collector (though not to the hospital itself as the original creditor). Within 30 days of receiving the collector's written validation notice, you can send a written request for debt validation, and the collector must cease collection activity until they provide written verification of the debt.
• You are facing a large balance and believe you may qualify for financial assistance. Nonprofit hospitals with federal tax-exempt status are required under IRS Section 501(r) to have financial assistance programs and must screen patients before taking extraordinary collection actions such as lawsuits or wage garnishment. Ask for the hospital's financial assistance policy in writing.
• The bill is substantial and the dispute is complex. A certified patient advocate or medical billing advocate can review your records professionally and often work on a contingency or flat-fee basis. An attorney specializing in medical billing may be appropriate if you are facing legal action over the debt.

What CPT Billing Codes Appear on Newborn Hearing Test Bills?

Hearing screening bills are frequently miscoded, and knowing the specific codes is the fastest way to verify whether you were charged correctly. Here are the CPT codes you are likely to see on a newborn hearing test claim:

• 92588 — Distortion product evoked otoacoustic emissions (OAE), comprehensive: The standard code for a full newborn OAE screening. This is the most common code for the routine hearing test performed before hospital discharge.
• 92587 — OAE, limited evaluation: A lower-complexity version of the OAE test. If your baby’s screen was the standard pass/fail birth screen, 92587 is more commonly appropriate than 92588. Billing 92588 when 92587 applies is a form of upcoding.
• 92585 — Auditory evoked potentials (ABR), comprehensive: The automated ABR (AABR) test — a more involved test that measures brainstem response to sound. Billed when the OAE screen is failed and a more diagnostic test is performed. If your baby passed the OAE screen and no ABR was performed, this code should not appear on your bill.
• 92586 — Auditory evoked potentials (ABR), limited: A screening-level ABR, sometimes performed as a follow-up to a failed OAE. Verify against your baby’s newborn records which test was actually administered.
• V72.11 / Z01.10 (ICD-10): The diagnosis code for an encounter for examination of ears and hearing. This should be the code associated with a routine newborn hearing screen — not a hearing loss code unless hearing loss was actually diagnosed.

EPSDT and Medicaid coverage: If your newborn was covered by Medicaid at birth, the Early and Periodic Screening, Diagnostic and Treatment (EPSDT) benefit covers the newborn hearing screen with no cost-sharing in most states. If you were billed out-of-pocket for a hearing screen on a Medicaid-covered newborn, request a review of how the claim was adjudicated. It may have been processed under the wrong coverage category.

State-mandated coverage: All 50 states require health insurance policies to cover the Universal Newborn Hearing Screening (UNHS) with no cost-sharing when performed before discharge. If your commercial insurer applied a deductible or cost-sharing to this test, your plan may have processed the claim incorrectly under federal ACA preventive care rules.
