ADA announces D4346 scaling procedure code

As of Jan. 1, dentists may use the CDT code D4346 for "scaling in the generalized presence of moderate or severe gingival inflammation — full mouth, after oral evaluation."  This code reflects the procedure for patients with gingival disease and no attachment loss. Dentists who have delivered the procedure have not previously been able to document and report it with an appropriate CDT code.

This 2017 CDT addition has been the subject of two ADA News articles, a guidelines document posted on, and a webinar that has been accessed by thousands of dentists and practice staff.

To learn more about this procedure and its new code – either for the first time or to refresh your memory – visit the CDT Code education page. Search for "Guidance on the D4346 Scaling Procedure" to watch the webinar and download the free publication Guide to Reporting D4346. The guide, first published in May, has been updated and incorporates content and feedback from the webinar.
