If your insurance company requests a refund from your dentist because your insurance cancelled is the dentist required to send the refund?

The only time the dentist is required to refund the insurance company, is after the specific company has already made payment to the dental office and inadvertently was an overpayment for services renderred. In the event that the dentist is a participating provider with the insurance company and has other patients with the same plan, the insurance company reserves the right to deduct the overpayment from any future payments owed to the dental office whether it is for the same patient or not.
