How would rise in cost be determined to be used as a qualifying event? 
I assume you 're referring to a rise in cost of your current health insurance premium . If the employee 's share of the annual premium is greater than 9.5 % of their annual household income , that would created a qualifying event . For an individual , and income change would be considered a qualifying event if your new income causes you to become eligible -LRB- or ineligible -RRB- for a subsidy -LRB- Advanced Premium Tax Credit -RRB- or if it causes you to have a change in your Cost Sharing Reduction -LRB- in other words , if you become eligible for a Silver 73 when you previously had a Silver 70 , for example -RRB- .
