Two codes defined by the American Dental Association's Code on Dental Procedures and Nomenclature are D0120 and D0180, as noted by RDH Magazine. The CDT code D0120 indicates a periodic oral evaluation performed on an established patient. D0180 describes a comprehensive periodontal evaluation of a new or established patient.
Another common CDT code is D0145, which is used to bill for oral evaluations of patients under three years old, explains Dentistry IQ. Comprehensive oral evaluations of either new or established patients are coded with D0150, and it includes screenings for oral cancer. The code D0160 is used for problem-focused follow-up oral evaluations.
Standard CDT codes are grouped into categories according to the type of dental service or the dental specialty typically necessary to perform the particular service, examination, procedure or supply, according to Dentrix. Categories of services include diagnostic, preventative, restorative, periodontics, oral surgery and orthodontics. Other CDT code categories include endodontics, prosthodontics, implant services, maxillofacial prosthetics and conditions.
Dental procedure codes from the most recent version of the CDT Code that was effective on the date of service must be used on any dental claims submitted electronically, as the American Dental Association. Dental explains. Claims submitted on paper forms also use the CDT Code.
