CDT / Code on Dental Procedures and Nomenclature
ADA’s consumer information is now available on MouthHealthy.org—our new website developed just for you. Visit MouthHealthy.org to find answers to all your dental-related questions so we can help you be Mouth Healthy for life.
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). 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 Code are published and effective biennially, at the start of odd-numbered years.
