Delta Dental Premier Plans
While most indemnity plans are not supported by a dental network, Delta Dental Premier is a network-based indemnity product.  This means that enrollees who choose to visit a Premier network dentist will on average have lower out-of-pocket costs than with other carriers' non-network-based indemnity plans.  Not only does Delta Dental Premier offer enrollees the freedom to visit any dentist, it also provides meaningful quality and cost protections.  Since Delta Dental Premier Dentists agree to accept fees that are generally lower than average submitted fees for an area, a Delta Dental Premier plan can potentially provide savings for both employers and employees alike. Over 92% of California and 75% of U.S. dentists are participating.
Delta Dental PPO plus Premier
Delta's unique PPO plan design feature - employers can take advantage of the savings from the PPO plan while providing employees with expanded access to Delta Dental dentists who can limit their out-of-pocket costs. 
Delta Dental PPO plus Premier combines the PPO and Premier networks to maximize opportunities to save money.  PPO dentists accept fees that are more deeply discounted than the fees accepted by dentists who participate in the larger Premier network.  Employees who visit a non-PPO dentist can save more by visiting a Premier dentist than they can by visiting a non-Delta Dental dentist.  PPO plus Premier provides maximum network access while offering deeper savings within the PPO network and a level of cost protection with the Premier network.
Dental Dental PPO dentists are reimbursed at the lesser of the submitted charge or the PPO provider's contracted fee. 
Delta Dental Premier dentists are reimbursed at the lesser of the submitted charge or the Premier provider's contracted fee. 
Non-contracted dentists are reimbursed at the lesser of the submitted charge or the fee that satisfies a majority of the dentists with the same training and geographical area.
PPO Classic Plans
Delta Dental PPO is Delta Dental’s preferred provider organization program. The program provides maximum benefit when you visit a PPO Dentist.  PPO dentists are Delta dentists who have agreed to charge PPO patients reduced fees.  Under the PPO program, you may visit any licensed dentist you wish.  However reimbursement will be based on the PPO provider’s contracted fee both in and out of network.  50% of California dentists are Delta Dental Preferred Providers.
