Marketplace Insurance refers to health insurance plans available through the Health Insurance Marketplace, a service that helps people find and enroll in affordable health coverage. Established by the Affordable Care Act, these marketplaces allow individuals and families to compare different insurance options based on their needs and budget. In the Marketplace, consumers can apply for financial assistance, such as premium tax credits and cost-sharing reductions, to lower their insurance costs. Enrollment typically occurs during an annual open enrollment period, but qualifying life events, like marriage or job loss, can allow for special enrollment opportunities.
