Starting January 1, 2023, audiologists can provide select hearing assessment services to Medicare Part B (outpatient) beneficiaries without a physician order under specific circumstances. Providing hearing assessment services for nonacute hearing loss without a physician order to Medicare beneficiaries requires careful attention to claims submission, medical record documentation, and patient balance billing.
This rule applies to hearing assessment services already covered under Medicare and does not expand coverage in any way beyond removing the physician order requirement under the limited circumstances described below.

A Medicare beneficiary can receive hearing assessment services without a physician order:
Medicare defines nonacute hearing loss as “a more gradual hearing loss that one may experience with advancing age, known as presbycusis.” In addition, only 36 Current Procedural Terminology (CPT® American Medical Association) codes can be provided without a physician order, as listed below.

When billing for approved nonacute hearing assessment services without a physician order, the “AB” modifier must be placed on the same claim line as the CPT code. On the CMS 1500 claim form, the CPT code and associated modifier are placed in Box 24D. If an audiologist provides three approved CPT codes on a date of service, the “AB” modifier would be applied three times, once for each CPT code. Audiologists should also continue to report CPT codes according to current coding guidelines, Correct Coding Initiative (CCI) edits, and Medically Unlikely Edits (MUEs).
As noted above, the hearing assessment services must be provided on the same date of service and can only be provided without an order once per Medicare beneficiary in a 12-month period. In the final rule, CMS states that it will provide future guidance on how to track when audiology services have been provided without a physician order. For example, other CMS limitations are tracked through an online portal known as the Common Working File (CWF) and via Medicare Administrative Contractor (MAC) phone-based Interactive Voice Response (IVR) systems. CMS might use these mechanisms to help audiologists determine if audiology services have been billed with the “AB” modifier in the last 12-months.
To help explain how these limitations work, please consider the following scenarios:
A Medicare beneficiary sees an audiologist in Vermont in June and the audiologist bills for these services with the “AB” modifier. In January of the following year, the beneficiary seeks hearing assessment services from an audiologist in Florida. Due to the 12-calendar month limitation, the Florida audiologist must obtain an order from the physician to receive Medicare payment for these services and could not bill for these services with the “AB” modifier. In this scenario, billing for audiology services with the “AB” modifier can occur after June.
A Medicare beneficiary sees an audiologist on Monday reporting nonacute hearing difficulties and does not have a physician order. The audiologist provides two hearing assessment services and bills each service with the “AB” modifier. On Thursday, the patient returns for additional testing. These services cannot be billed with the “AB” modifier and there must be a physician order on file for Medicare payment.
Audiology hearing assessment services can only be provided for nonacute hearing loss. Therefore, audiologists should not bill for services with the “AB” modifier and without a physician order for vestibular conditions.
In the future, CMS will provide additional guidance regarding beneficiary liability and the need for an advance beneficiary notice (ABN). For example, if an audiologist accidentally bills using the “AB” modifier on a second date of service for the same beneficiary within 12-months and the services are denied, this guidance will highlight if the beneficiary would bear financial liability and if an ABN is required.
As finalized, hearing assessment services can only be provided for nonacute hearing loss. Therefore, if an audiologist provides hearing assessment services for acute hearing loss, as defined by CMS, they should not bill for the services without an order and should not use the “AB” modifier. If documentation shows that an audiologist provided services to a Medicare beneficiary with acute hearing loss, the services could be denied on a post-payment review and Medicare could recoup the payments.
ASHA will continue to advocate for passage of the bipartisan and bicameral Medicare Audiologist Access and Services Act (H.R. 1587/S. 1731), which removes the physician referral requirement completely while appropriately expanding Medicare coverage to include both diagnostic and treatment services provided by audiologists.
As noted above, several key elements of this proposal still require additional guidance from CMS including:
This has potential financial consequences for audiologists and ASHA will provide updates as soon as more information is available. Audiologists should consider how and when to implement this in their practice and might even consider waiting until such guidance is available to mitigate their financial risk.
