One thing that stays constant is change — and there’s no exception when it comes to CDT codes.

The ADA’s code maintenance committee has released the additions, deletions, and editorial changes that will take effect on January 1, 2023. Code revisions take place based on the best interests of the profession, patients, and payers and will have varied effects based on their relevance and code usage for each dentist. The most notable changes for 2023 include revisions to the definition of an FMX and added tomosynthesis codes.


Here’s What’s New for 2023

  • 22 new codes
  • 2 deleted codes
  • 14 revised codes

Keep in mind that a new or revised code does not dictate reimbursement from insurance providers. In fact, codes may be recognized but not reimbursed at all. Consider it a language of sorts that providers and insurance companies understand; it helps communicate the services provided in numerical terms.


Updating Your System Annually With Code Revisions

  • Helps clarify treatment for team members, patients, and third-party payers
  • Provides accurate estimates for your patient base
  • Enables proper reimbursement from third-party payers

Most carriers notify in-network providers of their requirements and reimbursement protocols prior to the end of the year.


We Encourage You to Follow a Three-Part Protocol Annually

  • Reach out to insurance companies you’re contracted with to review processing guidelines for upcoming changes
  • Facilitate a team meeting where you discuss CDT changes and how their impact may shift chart note records, posting, and patient communication for the procedures you offer

  • Set fees for new codes and remove deleted codes from your billing software
