Audiology Billing

Audiology Billing That
Gets the AB Modifier Right.

One AB modifier claim locks every other AB-eligible code for that patient for 12 months, and Hearing Screening Associates paid $4 million in 2023 for billing evoked-potential tests audiologists never actually interpreted.

Common Billing Challenges

Where Audiology Billing Revenue Gets Lost

These are the six billing failure points we see most often in audiology practices — and the ones our team resolves systematically from day one.

🔒

AB Modifier 12-Month Lockout

Billing one eligible code with modifier AB blocks every other AB-eligible code for that patient for the next 12 months, not just that specific code.

🚫

Vestibular Codes Billed Under AB

Vestibular and balance testing codes are explicitly excluded from AB direct access — CMS returns those claims outright.

📅

Annual Frequency Limits Missed Per Visit

The 2-of-5 vestibular component rule and similar caps apply per patient per year, not per visit — a claim that looks correct in isolation can still deny as the third qualifying code in 12 months.

🦻

2026 Hearing Device Codes Billed to Medicare

The new 92628-92642 series has no assigned RVUs and remains non-payable under Medicare due to the Section 1862(a)(7) statutory exclusion, regardless of documentation quality.

🩺

Evoked Potential Claims Without Interpretation

A signed interpretation note is required for every 92585/92586 claim — Hearing Screening Associates paid $4 million after billing for automated results audiologists never actually read.

👤

Incident-To Attribution Errors

Services an audiologist personally furnishes as a direct Medicare benefit can't be billed incident-to a supervising physician; OIG's Work Plan added a Part B incident-to project in November 2024.

Common Questions About Audiology Billing

Straight answers to what practices usually ask before they switch.

Modifier AB allows an audiologist to bill Medicare directly for certain non-acute hearing assessment services without a physician or nonphysician practitioner order, under a rule finalized in the CY2023 Medicare Physician Fee Schedule and effective for claims processing since July 1, 2023. It applies to a specific list of CPT codes published by CMS, excludes vestibular and balance testing codes entirely, and can be used once every 12 months per patient. Billing one eligible code with modifier AB blocks all other AB-eligible codes for that same patient for the next 12 months, regardless of how many were performed on the same date.
No. Hearing aids themselves remain statutorily excluded from traditional Medicare Part B coverage under Section 1862(a)(7) of the Social Security Act, and this has not changed despite the complete overhaul of hearing device billing codes effective January 1, 2026. The new codes exist for billing transparency and for commercial payer and Medicaid use, not because Medicare now reimburses hearing aids. Diagnostic audiology services that assess hearing loss remain separately covered as diagnostic tests under Part B, which is a distinct benefit category from the hearing aid device itself.
Effective January 1, 2026, CPT deleted the legacy hearing aid service codes 92590 through 92595, which had been in use since 1993, and replaced them with 12 new codes across five categories: candidacy evaluation, hearing aid selection, fitting and follow-up, verification, and assistive device services. These new codes currently carry no assigned Medicare RVUs and remain non-payable under Medicare due to the statutory hearing aid exclusion. They apply only to air-conduction devices; implantable device programming codes such as 92601 through 92604 are unchanged.
Diagnostic audiology services performed by a technician can be billed incident-to a supervising physician. Services an audiologist personally furnishes as a direct Medicare benefit — including anything billed under modifier AB — cannot be billed incident-to; the audiologist must furnish and bill under their own NPI. OIG's November 2024 Work Plan addition on Medicare Part B incident-to payments makes this attribution distinction a live audit focus.
