Audiology CPT Codes for 2025 + Modifiers

Staying updated with the latest CPT codes and modifiers is crucial for audiologists to ensure accurate billing and compliance. Below are the updates for 2025.

Updated Audiology Codes for 2025

As of January 1, 2025, the Centers for Medicare & Medicaid Services (CMS) have not introduced new CPT codes specific to audiology services. However, it’s essential to stay informed about any mid-year updates or changes that may occur. For the most current information, refer to the official CMS website or the American Academy of Audiology.
