Maximize Your Savings with Delta DentalLearn How to Save the Most with a PPO Provider:

With nearly 80% of practicing dentists in Delta’s networks, there is a good chance you are already visiting a Delta Dental provider. To maximize your savings, it is important to be aware of the Delta network the dentist belongs to. Delta has three different networks of providers: PPO, Premier and Non-Delta dentists.

While you can visit any licensed dentist and still receive a benefit, you will save the most by visiting a Delta PPO or Premier dentist. Delta PPO and Premier dentists accept a pre-negotiated fee as payment instead of their usual fee. See below for an illustration of these savings which are outlined below.

Delta Dental PPO: Visit a dentist in this network to maximize your savings. In general, you should expect to save about 30% on contracted services which will help reduce any out of pocket costs you may experience. PPO dentists have pre-negotiated their fees with Delta and have agreed not to balance bill Delta patients.

Delta Dental Premier:  You will experience a smaller savings of 8-16% on contracted services by visiting a Premier dentist. Premier dentists have pre-negotiated their fees with Delta and have agreed not to balance bill Delta l patients.

Non-Delta Dental Dentists: While you will still receive a benefit from Delta while seeing an out-of-network dentist, these dentists do not have pre-negotiated rates with Delta. In addition, an out-of-network dentist may balance bill you the remainder of the bill Delta does not pay.
