Northeast Delta Dental will be doing system maintenance Saturday, June 15 from 12 p.m. to 8 p.m. Access may be limited during this time.

CDT 2024 code and policy changes

As of January 1, 2024, the American Dental Association’s (ADA’s) procedure code changes will be in effect. Associated changes to Northeast Delta Dental policies will also be effective January 1, 2024. There are 14 new codes and no deleted codes.

Please be sure not to submit claims for the new codes with dates of service prior to January 1, 2024. Your claims will be returned to your office for resubmission with the correct codes for the dates of service involved, which will result in unnecessarily delaying the processing of your claims.

The following are definitions of terms used in this article:

  • Denied/Deny: The procedure or service is not covered, and the approved amount is collectable from the patient.
  • Not Billable to the Patient (NBTP): The procedure is not benefited by Delta Dental nor is it billable to the patient by a participating dentist.
  • General Policy: This policy is already in place, and any charges related to office overhead, including infection control/PPE, are included in the fee for the dental services provided. Separate fees are not billable to the patient.
