The American Dental Association's Code Maintenance Committee has approved 67 changes to the Current Dental Terminology codes effective in 2027. The updates comprise 28 new codes, 33 revisions, and six editorial updates, announced on April 14, 2026.

What's changing in the 2027 CDT codes

The new codes address procedures that previously lacked specific coding options. Dentists now have dedicated codes for procedures such as removal of screw-retained indirect restorations, expanding the terminology system's coverage of restoration-related treatments. These additions and revisions reflect evolving clinical practices and the need for more precise procedure documentation.

Why billing and compliance matter

CDT code updates directly affect claim submission, insurance processing, and practice revenue cycle management. Dental practices must update their billing software and staff training to use the new codes correctly starting in 2027. Incorrect or outdated code usage can delay reimbursement and create compliance issues with payers.
