If an employee does not elect Medical, and then elects Medical FSA, a fee is assessed.
The fee is normally the employee-paid fee field named EmployeeMonthlyFee found in the Rates tab of the benefit plan.

// If not covered in the Medical plan, FSA fee is added at 2 * pay-period = monthly

var appMedical = Event.Applications["Health"]; if (appMedical != null && appMedical.ApplicationDate && !appMedical.Waived) { Event.Config.EmployeeMonthlyFee = 0; } else { Event.Config.EmployeeMonthlyFee = 3.50; }
