Code on Dental Procedures and Nomenclature (CDT)
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 Meeting
The CMC met on February 27 - March 1, 2014 to determine which of the 119 CDT Code substantive and editorial action requests on the committee’s agenda to accept or decline. Official notice of the CMC’s decisions will be in the “Action Report” scheduled to be posted on this web page by April 4, 2014.
Accepted actions will be effective in CDT 2015.
Request a CDT Code Addition, Revision, Deletion
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.
