Code on Dental Procedures and Nomenclature (CDT)

Policy Number: DP-X-001

Last Updated: Sept. 15, 2022

To report treatment, use the American Dental Association (ADA) Code on Dental Procedures and Nomenclature (CDT). The CDT is revised periodically by the ADA. When codes are added or deleted by the ADA, Blue Cross and Blue Shield of Nebraska changes our claim processing system accordingly. Use only the codes listed in the most current version of CDT when reporting services to us. Claims with codes NOT in the current CDT will be invalid for processing and returned.  

The latest revision of CDT is available through:
