New CDT Codes for 2024

January 31, 2024

The Code Maintenance Committee approved four new codes that reflect ADA policy on the role of dentistry in the treatment of sleep apnea, along with 10 other additions and two revisions to the CDT Code that went into effect on Jan. 1, 2024.

The CMC also approved a code for immunization counseling, which is described as a review of a patient’s vaccine and medical history and discussion of the vaccine benefits, risks and consequences of not obtaining it. This procedure may be reported for any type of vaccine, and also includes a discussion of questions and concerns the patient, family or caregiver may have and suggestions on where the patient can obtain the vaccine.

Other code additions concern the following procedures:
• 3D printing of a 3D dental surface scan.
• Band stabilization — per tooth.
• Excavation of a tooth resulting in the determination of non-restorability.
• Application of hydroxyapatite regeneration medicament — per tooth.
• Accessing and retorquing loose implant screw — per screw.
• Excisional biopsy of minor salivary glands.
• Indexing for osteotomy using dynamic robotic assisted or dynamic navigation.
• Fabrication and placement of a custom removable clear plastic temporary aesthetic appliance.

The CMC also approved clarifying revisions of two existing codes:
• D2335 resin-based composite restoration — four or more surfaces (anterior). The revision deleted mention of the incisal angle, which is not a tooth surface and caused coding confusion as well as claim preparation delays when dentists or practice staff contacted the ADA for clarification.
• D5876 add metal substructure to acrylic, full denture (per arch). The revision added a descriptor stating that this procedure involves addition of a metal substructure to strengthen the prosthesis.
