Usual, Customary and Reasonable (UC

UCR refers to the fee guidelines that are used to pay claims. UCR is used if you have a PPO plan but visit an out-of-network dentist.

It is important that you understand what level of UCR your plan pays, because it can affect the payment of your claim and your out-of-pocket costs. Your dental plan summary will tell you what your plan pays.
