Important information about the TRICARE Retiree Dental Program (TRDP) On December 31, 2018, the current TRDP contract and dental benefits under the Department of Defense program will end. However, dental coverage for the TRDP retirees and family members will be offered under the Federal Employee Dental and Vision Insurance Program (FEDVIP). Delta Dental offers coverage in the FEDVIP with two plan options available to TRDP members. To continue coverage in 2019, your TRDP patients will need to select a FEDVIP plan during the 2018 FEDVIP Open Season between November 12, 2018 and December 10, 2018. Visit trdp.org/dentists for more information. Please help prevent any gap in dental coverage for your TRDP patients and their families by directing them to TRICARE.benefeds.com to learn more.
