Marketplace insurance refers to health insurance plans that are available for purchase through the Health Insurance Marketplace, a service created under the Affordable Care Act. This platform allows individuals and families to compare different insurance options, helping them find coverage that fits 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 special enrollment periods may be available for qualifying life events, such as marriage or job loss.
