Dental benefits administered by United Concordia. Your dental plan is the Concordia Flex plan. Concordia Flex is a Fee-for-Service (FFS) plan that provides you with access to more than 263,000 practicing locations nationwide through our Advantage Plus Network. If your dentist does not participate, you may still use your dentist, but your out-of-pocket expenses may be higher. Choosing one of our participating providers helps lower out-of-pocket costs and eliminates the need to fill out claim forms.
