d0431 dental code

 As explained by the experts at DentalRevu, the D0431 Dental Code initially used to represent a “Genetic Test for Susceptibility to Oral Diseases”. This involved collection of samples for certified laboratory examination in order to detect particular genetic variants associated with higher susceptibility to oral disorders such as severe periodontal disease.

The code was all-inclusive in the sense that it was used for reporting both the collection of the lab report and sample. For example, if a dentist were to prescribe a MyPerioIDSM PST® Test, the biller would code it as D0431, but this CDT code was seldom covered by any dental plans.

2022 Update to the D0431 Dental Code

According to the CDT Dental Code update for 2022, D0431 is a screening test for visual cancer detection; it is not to be mistaken with a biopsy, which is coded differently (possibly D7288 brush biopsy which harvests transepithelial cells).

A biopsy or referral to an oral surgeon may be considered if the dentist notices abnormalities in the mucosa during a visual examination of the mouth. Often, this service is introduced during the hygiene visit.
