Current Dental Terminology (CDT) or Code on Dental Procedures and Nomenclature, developed and updated by American Dental Association (ADA), is a set of codes with descriptive terms to report dental services and procedures. The purpose behind using CDT code is to bring uniformity and accuracy in documenting dental treatment. Dental practices need to be updated with the coding changes. 

ADA introduced around 37 new codes this year, effective from Jan 1, 2020, and this article will talk about the new CDT 2020 dental procedure codes.
