Obamacare is not a type of medical coverage, so it does not cover anything. The Affordable Care Act, often referred to as "Obamacare," was signed into law in 2010 and made changes to how health insurance is dealt with in the United States. In particular, it makes it easier and more affordable for all citizens to have adequate medical coverage.
The Affordable Care Act has created ways for lower-income people to get affordable coverage if they do not qualify for Medicaid. It has also increased the guidelines so more people qualify for Medicaid. This reform has expanded Medicaid to 15.9 million people who were previously not qualified.
Under the Affordable Care Act, people can no longer be denied insurance because of pre-existing conditions. They also can no longer lose coverage if they become sick, and insurance companies can no longer make drastic rate increases.
Employers of large companies must offer all full-time employees a chance to get insurance through them. Small businesses get a tax break if they offer insurance for their workers.
Everyone in the U.S. must have medical coverage. As of 2014, enrollment for coverage is only open once a year during an annual open enrollment period. If a citizen who can afford insurance does not get coverage or an exemption, a fine is added to their income taxes..
