Open Enrollment For 2019 Benefits

October 9th - November 9th, 2018

Open Enrollment is your opportunity to make/change your plan elections and add/drop dependents for the upcoming year. With the exception of the Healthcare and Dependent Care Flexible Spending Accounts (FSA) and the Health Savings Account (HSA), all your current benefit elections will automatically rollover unless you make a change during Open Enrollment.

  • Selections made during Open Enrollment will be effective January 1, 2019 to December 31, 2019
  • You can review your current benefits by logging on to Workday anytime, either at work or at home.
  • You will be able to make changes, without a qualifying event, starting October 9th through November 9th.

**If you wish to continue your Flexible Health or Dependent Care Spending Account (FSA) or Health Savings Account (HSA)you must elect an annual amount during each Open Enrollment as this amount will not rollover from the previous plan year.**  

  • The maximum amount you may contribute to a Healthcare Flexible Spending Account for the 2019 plan year is $2,650.
  •  The maximum amount you may contribute to a Dependent Day Care Flexible Spending Account is $5,000 a year.

Hospital Indemnity Insurance provides a specific dollar benefit for each eligible hospital stay. These payments provide a cushion to enhance your current medical coverage. This can help you avoid dipping into your savings or having to borrow money for out-of-pocket expenses like co-payments, transportation, meals for family members, extra help with child care, or time away from work for you or your spouse.  This is a good supplement to our High Deductible Health plans.

An accident can happen when you least expect it. Other things you may not expect after an accident are out-of-pocket medical costs, extra living expenses, or even lost wages due to being off work.  If a serious accident happened, would your savings cover the unexpected health and living expenses you may incur? This plan pays a specific dollar amount for each eligible accident.

A critical illness can be life-changing due to both the physical challenges and extra medical and living expenses. A diagnosis of cancer, a heart attack, stroke, or other serious illness is scary enough without having to worry about paying your bills or draining your savings account.  This plan will provide a specific dollar benefit for eligible Critical Illnesses to help you’re your expenses so you can focus on your recovery.
