The Health Insurance Marketplace at HealthCare.gov, established under the Affordable Care Act and operated by CMS, lets individuals and families compare and enroll in private health insurance plans. Most enrollees qualify for premium tax credits and cost-sharing reductions based on household income, and Marketplace plans must cover essential health benefits.
