Kathy Forbes will be presenting What is the CDT Procedure Code for a ‘Cleaning’? Oh wait! There IS no code for ‘Cleaning’.

When did licensed, professional dental hygienists become tooth janitors?? Today’s
advertisements promote: “Get a cleaning, exam and digital x-rays for $59.” “A teeth cleaning by a dental
hygienist or other dental professional is a 30-60 minute procedure.” And on, and on goes the advertising.
What is the American Dental Associations’ CDT procedure code for “Cleaning”? As a presenter of
the CDT procedure codes since 1992, there has NEVER been a procedure code for a “cleaning”. So, what
procedure do you select once a diagnosis has been determined?
There are currently seven CDT procedure codes from which hygienists select when preparing a
treatment plan. None of them have the word “cleaning” in their descriptor. But clearly, a diagnosis is
necessary. Now that the CDT Manual includes ICD-10 diagnostic codes, it will be up to the clinician to
select the most appropriate diagnostic code/codes which describe the patient’s oral condition. Only then
can the correct CDT procedure code be recommended.
By the end of the presentation, participants will be able to:
• Discuss and understand the specific elements of a Comprehensive Oral Evaluation (D0150), the
Comprehensive Periodontal Evaluation (D0180), the Periodic Oral Evaluation (D0120) and the Assessment of
a Patient (D0191), each necessary to determine the correct CDT procedure.
• Discuss and understand the specific elements of the 7 CDT “cleaning” procedure codes and what criteria are
needed to select the appropriate code, especially with the latest changes to D4355.
