Calendar Year 2023 Open Plan 

Calendar Year 2023 Closed Dental Plans

  • Altus Dental Plans
  • Optical Benefits with Altus Dental Plan and DeltaCare Plan (see plan listed below)


An employee, spouse and children are eligible for dental/optical coverage under one of the available plans after the employee completes two months employment in a MOSES represented position.  The age at which eligibility for children ends depends on the plan chosen; please refer to the different plans for additional information on this matter.

An employee may not have to wait two months for coverage if they enter a MOSES represented position from another public entity that offers dental/optical coverage provided there is a reciprocal agreement that waives the waiting period for MOSES represented employees that become employed by that public entity.  If you believe waiving of the waiting period for dental/optical benefits applies to you, please contact Tom Prendergast at

An employee also may not have to wait two months for coverage if they were laid-off from a MOSES represented title and is returning within 3 years of the layoff to a MOSES represented position. If this situation applies to you, contact Tom Prendergast at

​Under the Open Dental Plan, members can go to any legally qualified dental professional and be covered for dental work other than bleaching or similar services.  There is no co-insurance charge but there are limitations on reimbursements as described in the Plan Details.  Open Plan members are required to pay for services provided.  At the end of each plan year new reimbursement forms are sent to every eligible member and reimbursement forms are then submitted with copies of paid receipts to the Plan Administrator who reviews and processes the reimbursement requests and mails reimbursement checks to Plan members based on approved reimbursable expenses.

New employees are placed in the Open Plan unless they specifically request enrollment into one of the Closed Dental Plans.
