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.

FAQs related to Dental Procedure Codes
There are a lot of general questions asked frequently, usually by dental practitioners, related to CDT codes. Let’s take a look at them.
Qus. Why is CDT code updated annually?
Ans. Dental treatment/procedures are continuously evolving and the CDT code is required to document the dental services accurately. To stay updated with the changes in dental services, ADA needs to update the CDT code annually.
Qus. Who requests for CDT code additions, changes, or revisions?
Ans. ADA’s Council on Dental Benefit Programs, third-party payers, and dental specialty organizations request for the changes. Dentists also request for revisions and additions.
Qus. How do I know the exact code, to document the service I have given to my patient?
Ans. ADA recommends all the dentists to keep the updated CDT manual to make sure that they are documenting the given treatment/procedures accurately. The dentists and the billing staff are advised to give a thorough study of the codes to accurately document the procedure performed.
Qus. Where can I get more information about the CDT code?
Ans. The first point of contact is the ADA Member Service Centre (MSC). If there is any complex query related to CDT code, it’s forwarded to the Centre for Dental Benefits and Coding and Quality staff. ADA members can contact the MSC through the toll-free number/email: 312-440-2500/ email@example.com.
