Which of the following is an example of a qualifying life event for a Special Enrollment Period?

A qualifying life event is a change in a person's situation that allows them to enroll in health insurance outside of the standard enrollment period. Marriage is a significant life event that triggers a Special Enrollment Period because it typically signifies a change in household status. When individuals marry, they often need to reassess their health insurance needs and might want to combine their plans or enroll in a new one altogether. This event can lead to the addition of a spouse to a health plan or the option to switch to a more suitable policy that covers both individuals.

In contrast, changing jobs or receiving a promotion does not directly create a need for immediate health insurance enrollment changes applicable to a Special Enrollment Period, as these do not inherently alter household composition. Changing telephone numbers is not a qualifying life event at all, as it does not impact health coverage or necessitate a reevaluation of health insurance needs.
