For Middlesex Country and Board of Social Services Employees

Effective January 1, 2018 CIGNA Dental Care will replace the Aetna Dental Plan as the Dental HMO option.
The Delta Dental Plan will remain the same.

  • If you have the Aetna Dental Plan, there will be no change to the current benefits other than using the CIGNA Dental Care HMO network. CIGNA's Dental Care DHMO network is huge and in most cases you may retain your present Dentist. You will receive a Welcome Kit and ID card from CIGNA mid-December 2017. If your Dentists's name is on the ID card, you will be able to obtain your Dental benefits on January 1, 2018 without issue. If no Dentist is specified on your ID card, you will need to use the CIGNA website at (or log into (after January 1), or call CIGNA at 800.Cigna24 (800.244.6224) to pick a new Dentist and have it updated. Once you pick a new Dentist, CIGNA will send you a new dental ID card.
  • If you have the current Traditional Delta Dental Plan and want to stay with Delta, no action is necessary.
  • The MCJHIF will also offer the Detla Dental PPO Plus Premier Plan (Premier). The Premier plan offers significantly higher allowances for all dental procedures but selection of this option will require an increased payroll deduction.
  • If you would like to change to the new Premier Plan or the CIGNA Dental Care Plan, you may do so during Open Enrollment which begins November 1, 2017 and runs through November 30, 2017.
