CDT Code
Also written as: CDT — Code on Dental Procedures and Nomenclature
A standardised alphanumeric code system maintained by the ADA used to identify and bill dental procedures.
Full Definition
CDT (Code on Dental Procedures and Nomenclature) codes are a set of alphanumeric codes developed and maintained by the American Dental Association (ADA) to uniformly describe dental procedures for billing and insurance purposes. Each code begins with the letter 'D' followed by four digits (e.g., D0120 for a periodic oral evaluation). Editors working on dental insurance documents, treatment plans, or clinical notes must ensure these codes are formatted consistently and accurately. Incorrect transcription of CDT codes can lead to claim denials or compliance issues. The code set is updated annually, so editors should verify currency when reviewing clinical or billing documents.
Usage
Usage note: Always rendered as a capital 'D' followed by four digits. Do not spell out or paraphrase CDT codes in clinical billing documents.
