The CDT 2025 update is now available from the American Dental Association (ADA), bringing important changes to the coding and nomenclature used in dental procedure reporting. As a reminder, federal HIPAA law mandates the use of CDT codes in all electronic health care transactions.

Beginning January 1, 2025, providers must use CDT 2025 codes when submitting claims to Delta Dental and other carriers for services performed on or after this date.

What's Changing in CDT 2025

The 2025 update includes:

• 10 New Codes

• 12 Revised Codes

• 2 Deleted Codes

• Several Policy Revisions

Please note that coverage for new codes is determined by each patient’s specific benefit plan.

The Delta Dental Dentist Handbook will be updated to reflect CDT 2025 by January 1, 2025. Dentists can access the revised handbook through Provider Tools at deltadentalins.com/dentists.

Key Reminders

• CDT coding and nomenclature are copyrighted and trademarked by the American Dental Association.

• There may be differences between CDT descriptors and Delta Dental’s plan benefits or processing policies.

• Fees for services not billable to the patient cannot be charged to the patient or to Delta Dental.

• Patients are responsible for fees on denied services.

• Italicized text in Delta Dental’s communications is intended to clarify benefits delivery and is not part of the ADA’s CDT 2025 codes.
