The Expatriate Dental Plan covers a wide variety of services, as long as the services are necessary and their costs do not exceed reasonable and customary (R&C) charges. (Please see "Defined Terms" for the definitions of "Necessary Services" and "Reasonable and Customary Charges.") The following lists include examples of covered services, but the lists are not exhaustive and coverage remains subject to any Plan requirements or limitations. For specific information on covered services and frequency limits, please contact Cigna Global Health Benefits. The list of covered services may change at any time.
