CDT^® - Current Dental Terminology^® Dental Code Set (D0000-D9999)

The Current Dental Terminology (CDT) code set is maintained by the American Dental Association.

Accurate recording and reporting dental treatment is supported by a set of codes that have a consistent format and are at the appropriate level of specificity to adequately encompass commonly accepted dental procedures. These needs are supported by the Code on Dental Procedures and Nomenclature (Code).

On August 17, 2000 the Code was named as a HIPAA standard code set. Any claim submitted on a HIPAA standard electronic dental claim must use dental procedure code from the version of the Code in effect on the date of service. The Code is also used on dental claims submitted on paper, and the ADA maintains a paper claim form whose data content reflects the HIPAA standard electronic dental claim.

The Code is periodically reviewed and revised to reflect the dynamic changes in dental procedures that are recognized by organized dentistry and the dental community as a whole. Revisions to the codes are published and effective annually.
