ADA Code Sets: Licensing for Commercial Users

CDT Code Set

American Dental Association (ADA) developed Current Dental Terminology (CDT®) as a standardized language to help dentists and other members of the healthcare industry communicate effectively. CDT is revised and updated every year.

The ADA is the exclusive copyright owner of CDT, the Code on Dental Procedures and Nomenclature (the Code), and the ADA Dental Claim Form. Except as permitted by law, all use, copying or distribution of CDT, or any portion thereof (including the Code on Dental Procedures and Nomenclature) in any product or services (including works prepared for clients by consultants and other professionals), whether in printed, electronic or other format, requires a valid commercial user license from the ADA.

License Agreement

The ADA will provide a template license agreement that reflects the appropriate terms, conditions and royalty fees for your product or service. These terms and conditions were developed to protect the ADA intellectual property and ensure that organizations bundling the CDT Codes within their products or services are treated fairly and equitably regardless of organizational size, industry or mission.

To obtain a license, commercial users must complete and return a CDT License Application to the ADA. Incomplete applications will be returned to the applicant for completion. For further questions regarding CDT Licensing, please contact the ADA at Please note it typically takes 2-4 weeks for the ADA to process a CDT License Application, but in some cases the process can take as long as two (2) months.

License Types

The ADA strives to make CDT widely available at a reasonable cost to the entire healthcare community, including commercial users. Because there are a number of ways to bundle the CDT Codes with your product or service, the ADA has a number of different license types including, but not limited to: software, published materials (print or digital), seminars/webinars, consultants, benefit plans or TPAs.

With commercial use, you must bundle the Codes with other assets in your product or service and redistribution of the CDT Codes alone is not permitted. Bundling of the Codes in your product/service includes access, use, extraction, interpretation or manipulation of the Codes in or into your product/service to produce or enable output (patient records, data, reports, claims, analytics, books, training materials or the like) that could not be created without the CDT Codes embedded in the product/service even if the CDT Codes may not be visible or directly accessible.
