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 and its meetings.

2014 CMC Action Reports

The following reports, available for review or download, document the outcome of Code Maintenance Committee action on requested CDT Code changes.  These requests were on the CMC’s February 27 - March 1, 2014 meeting agenda.   Accepted requests will be incorporated into CDT 2015, which is effective January 1st.

The Substantive Action Report contains requests for CDT Code additions, as well as deletion of or significant revisions to existing CDT Code entries.  The Editorial Action Report contains requests to correct grammatical and format errors in existing CDT Code entries that do not affect their purpose or scope.

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.
