HealthCare.gov

HealthCare.gov is a health insurance exchange website operated by the United States federal government under the provisions of the Affordable Care Act (ACA), informally referred to as "Obamacare", which currently serves the residents of the U.S. states which have opted not to create their own state exchanges. The exchange facilitates the sale of private health insurance plans to residents of the United States and offers subsidies to those who earn between one and four times the federal poverty line, but not to those earning less than the federal poverty line. The website also assists those persons who are eligible to sign up for Medicaid, and has a separate marketplace for small businesses.
On October 1, 2013, HealthCare.gov was rolled out as planned, despite the concurrent partial government shutdown.
