The United Concordia Dental plan is a passive Preferred Provider Organization (PPO) plan. Dental providers in the network have agreed to accept negotiated rates. However, members have the freedom to choose any licensed dentist. Members are not required to choose a dentist at the time of enrollment. If you use an out-of-network dentist, you may be responsible for charges over what United Concordia Companies, Inc. (UCCI) pays. A network dentist cannot balance bill you or your dependents. The negotiated rate must be considered payment in full.
