CDT 2024 is the newest version of the American Dental Association’s code on dental procedures and nomenclature. Federal HIPAA law requires that CDT codes be used in electronic health care transactions. When the ADA changes the codes, carriers must adopt the changes. Please use CDT 2024 codes when submitting claims to Delta Dental for services you perform on or after January 1, 2024.
The changes include 14 new codes, one new category of service (sleep apnea), two revised codes, no deletions and several policy revisions. Following is a summary of the changes; please note that coverage for new codes is dependent on the patient’s particular benefit plan.
