This is a summary of deductible, coinsurance, out-of-pocket limits, and other components of plan design. All coverage provisions, limitations and exclusions can be found in the group contract and certificate of coverage. Some Covered Services for Pediatric Enrollees require that you obtain a Prior Authorization from us before the service is performed. The covered dental services that require Prior Authorization are described in the certificate of coverage. Where Prior Authorization is required but not obtained, Delta Dental can apply a penalty of up to 50% of the charges that would otherwise be covered.
