You should report it to PSIC immediately. Even if you aren't sure whether the situation is an actual claim or licensing board investigation, call the PSIC Dental Claims Department at 1-800-640-6504. Our professional claim representatives will help you determine the best course of action. You will not jeopardize your coverage by asking if you have a claim or investigation. We may help you use your coverage to its fullest advantage or point you to resources of which you may not be aware.
The licensing board is there to protect the consumer - not the dentist. You need the experience of an attorney familiar with licensing board investigations. Even seemingly innocuous questions can be fraught with pitfalls for a dentist unfamiliar with licensing board investigations.
