Step-by-step explanation:
The CDT codes for dental hygiene refer to the Current Dental Terminology, which is a set of codes used by dental professionals to streamline communication and documentation for dental procedures. They are crucial for billing and insurance purposes. Each code is a unique identifier that corresponds to a specific dental service, making it easier to track and manage patient care. Examples include D1110 for an adult prophylaxis or teeth cleaning, D1120 for a child prophylaxis, and D1208 for a topical application of fluoride.
