The American Dental Association (ADA) has announced changes to the Code on Dental Procedures and Nomenclature (CDT Code) for 2019. These Current Dental Terminology (CDT) codes help to achieve uniformity, consistency and specificity in accurately documenting dental treatment. It also helps with the efficient processing of dental claims. Effective January 1, 2019, the CDT 2019 updates include 15 additions, five revisions and four deletions. Dentists as well as dental billing companies must stay updated with such dental code additions, revisions and deletions. As dental procedures continually evolve, annual CDT coding updates are crucial to effectively accommodate that evolution.
The California Dental Association (CDA) recommends all dental offices to have a current copy of the CDT to assist with proper claim billing.

- D9940 occlusal guard, by report (Removable dental appliances, which are designed to minimize the effects of bruxism (grinding) and other occlusal factors)
For dental coding, practices have to code for what they have done, not what is covered under the patient’s benefit plan. In cases where coders can’t find a code to describe a procedure, CDA recommends using the appropriate unspecified procedure code, by report, or the 999 code, along with the supporting narrative describing the service provided:
D4999 unspecified periodontics procedure, by report
According to the August 2017 survey conducted by NEA, three troublesome CDT codes were identified as D4341, D2740, and D2950, which require the most supporting documentation for adjudication, and the claims with these codes most often get rejected by payers after first submission. Professional dental medical billing and coding services provided by reliable medical billing and coding companies help practices receive maximum reimbursement for splints, bone grafts, oral implants, tooth fractures or any other procedures.
