Which CDT code is used to report a full mouth debridement to enable a comprehensive periodontal evaluation?
Answer: D4355
D4355 is specifically designated for full mouth debridement, a gross removal of plaque and calculus that interferes with a comprehensive oral evaluation.
What is the CDT code for periodontal scaling and root planing involving four or more teeth per quadrant?
Answer: D4341
D4341 covers periodontal scaling and root planing when four or more teeth per quadrant are treated, distinguishing it from D4342 which covers one to three teeth.
Which CDT code is reported for periodontal maintenance following the completion of active periodontal therapy?
Answer: D4910
D4910 (periodontal maintenance) is used after a patient has completed active periodontal therapy to maintain periodontal health, and is distinct from routine prophylaxis.
What CDT code represents a prophylaxis procedure for an adult patient?
Answer: D1110
D1110 is the CDT code for prophylaxis in adult patients (typically 14 years and older), involving removal of plaque, calculus, and stains.
What is the key clinical distinction between CDT codes D4341 and D4342?
Answer: D4341 covers four or more teeth per quadrant; D4342 covers one to three teeth per quadrant
The only clinical distinction between D4341 and D4342 is the number of teeth treated: D4341 applies to four or more teeth per quadrant, while D4342 applies to one to three teeth per quadrant.
Which CDT code is used to report a comprehensive periodontal evaluation for a new or established patient?
Answer: D0180
D0180 is designated specifically for a comprehensive periodontal evaluation that includes a detailed assessment of periodontal conditions, probing, and radiographic interpretation.
Under what clinical circumstance should D4910 (periodontal maintenance) be used instead of D1110 (adult prophylaxis)?
Answer: After the patient has completed active periodontal therapy such as scaling and root planing
D4910 is appropriate only for patients who have a prior history of active periodontal therapy; once a patient has undergone SRP or periodontal surgery, subsequent supportive care visits are reported as D4910.
