By Anna Marie Jilla and Carrie Kovar This article is a part of the November/December 2023, Volume 35, Number 6, Audiology Today issue. The objective of this article is to review coding guidance for services covered under the Centers for Medicare and Medicaid Services (CMS) policy of limited direct access to an audiologist for the provision of certain audiology services (CMS, 2022b). CMS noted that the change in coding for certain audiology services would require multiple changes to claims-processing systems and take time to fully operationalize. Indeed, guidance from CMS and the Medicare Administrative Contractors (MACs) has been limited; thus, we want to highlight the latest resources on billing with the AB modifier.
