CDT-2009 is the newest version of the American Dental Association’s Current Dental Terminology. The federal HIPAA legislation requires that it be used in electronic health care transactions. When the ADA changes the codes, carriers must adopt the changes. Please begin to use CDT-2009 codes when submitting claims to Delta Dental State Government Programs for services you perform on or after January 1, 2009 for the Healthy Families and similar programs. For services provided in 2008, you should continue to use CDT-2007 codes. Copies of CDT-2009 will be available for purchase from the ADA. Information is available on the ADA web site.
