We have recently learned about the Dr. Chao Pinhole Technique Perio treatment and was curious if you knew which CDT code is best suited for insurance billing. Thank you in advance for your assistance.

This is a new procedure and none of the current CDT codes are compatible, therefore, the most appropriate code at this time is D4999. In the remarks area of the ADA2012 claim form you need to put "Chao Pinhole Technique performed."
