CDT: Code on Dental Procedures and Nomenclature


The purpose of the CDT Code is to achieve uniformity, consistency and specificity in accurately reporting dental treatment. One use of the CDT Code is to provide for the efficient processing of dental claims.

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

Annual Review and Revision

The Council on Dental Benefit Programs (CDBP) has ADA Bylaws responsibility for CDT Code maintenance. To fulfill this obligation CDBP established its Code Maintenance Committee (CMC), a body that includes representatives from various sectors of the dental community (e.g., ADA; dental specialty organizations; third-party payers). CMC members cast their votes to accept, amend, or decline CDT Code change requests.

Please see Code Maintenance Committee (CMC) page for information about the CMC's members and its meetings and reports of the past actions.

Next CMC Meeting

The next annual three-day CMC meeting is scheduled to convene at ADA Headquarters in Chicago on March 5 - March 7, 2015 (Thursday-Saturday). Proceedings are from 8:00 am to 5:00 pm daily and will take place in the 2nd floor Auditorium.

  • This is an open meeting that includes public comment and discussion of any CDT Code action request before the committee.

  • The CMC meeting is when member organization representatives discuss and vote to accept, amend or decline each action request.

The CMC will address seventy-four substantive and eight editorial CDT Code Action Requests during this meeting. These actions are summarized on their respective inventories, which are available to any interested person or organization.

Request a CDT Code Addition, Revision, Deletion

CDT Change requests may be submitted at any time, and the date received determines the CDT Code version that may incorporate the requested action. The annual closing date for submissions is on the CDT Code Maintenance timeline. Any requests received after the closing date will be addressed in the next annual maintenance cycle.
