Changes to the “Code on Dental Procedures and Nomenclature,” commonly known as the CDT Code, are updated annually to reflect changes in dental procedures accepted by the dental community.


Any dental claim submitted electronically or paper must use procedure codes from the current version of the CDT Code. The 2022 version of the CDT Code includes 16 new procedure codes, 14 revised codes and 6 deleted codes.


Please take note of the deleted Interceptive Orthodontic Treatment subcategory, codes D8050 and D8060. These codes should be reported with the applicable Limited Orthodontic Treatment codes; D8010, D8020, D8030 or D8040.


With all new code changes, we recommend that dental offices verify covered services for patients before rendering treatment. Details of individual patient benefits are available online through the Dental Office Toolkit.


Accurate coding promotes faster claim processing and fewer errors. To order a copy of the 2022 CDT Code, call the ADA at 1-800-947-4746, or go online at
