Final answer:
Isabella can change her employer-based health insurance plan during open enrollment, when she gets married, and when she has a child.
Step-by-step explanation:
Isabella can change her employer-based health insurance plan in three situations:
- When her company has an open enrollment period: This is a designated time when employees can make changes to their insurance coverage, including switching plans.
- When she gets married: Marriage is considered a qualifying life event that allows individuals to make changes to their insurance plans outside of an open enrollment period.
- When she has a child: Having a child is also a qualifying life event that allows individuals to make changes to their insurance coverage.
