A. For simple requests, the Evidence of Coverage located in the left column of this page is the easiest way to determine coverage. This Evidence of Coverage refers to procedures using standardized dental codes. When pricing procedures yourself, it is in your best interest to request those dental codes from your dentist and match them to the Evidence of Coverage. A more time consuming, but in many cases a more accurate, way to determine coverage is to ask that your dentist request an Estimate from Delta Dental. As with all pricing, it is in your best interest to price procedures before having them done.
