What Is Obamacare?
Obamacare's primary intention is to give all Americans the ability to purchase affordable health insurance. There are several different parts to the law that each affected a different aspect of health insurance access. Here are some of the more well-known:
- Individual Mandate
One of the most-talked-about aspects of the ACA was its provision stating that everyone is required to have health insurance. Those who do not have health insurance face a tax penalty.
- Coverage of Pre-Existing Conditions
Another one of the biggest changes ACA made was to prohibit insurance companies from denying someone coverage or charging them more because of a pre-existing condition. And because as many as 1 in 2 Americans have some type of pre-existing condition, this provision has been one of the law’s more popular.
- Health Insurance Subsidies
Under Obamacare, people who qualify for financial assistance are eligible for health insurance tax credits to help offset the cost of their insurance.
- Exchanges
Exchanges, or online marketplaces for health insurance, are how people are supposed to purchase affordable insurance policies under the ACA. Private health insurance companies offer policies in the marketplace and compete for the business of shoppers. Any legal citizen can purchase insurance from the exchanges, but not everyone qualifies for the low-income subsidies.
The Obamacare Health Insurance Exchange Marketplace first opened in 2013, and by 2023 more than 16 million people annually were using the exchange to enroll in coverage.

Medicare vs Obamacare
Medicare is insurance provided by the federal government for people over the age of 65 and the disabled, and Obamacare is a set of laws governing people’s access to health insurance. There is no one type of policy that is considered “Obamacare.” Under Obamacare, private insurance companies compete for business by offering affordable plans with different levels of coverage. Unlike Obamacare, coverage under Original Medicare is provided specifically by the federal government.
Only people aged 65 and up and certain younger people with qualifying disabilities (like End-Stage Renal Disease) are eligible to be on Medicare. Unlike Medicare, any U.S. citizen buying his or her own health insurance is eligible to purchase a plan off of one of the exchanges set up by Obamacare.
Obamacare vs Medicaid
Medicaid is similar to Medicare but is designed for people of lower income levels. Unlike Medicare, qualifying criteria for Medicaid varies by state.
Is Medicare the Same as ACA?
No, Medicare is not the same thing as the ACA. Obamacare and the Affordable Care Act govern what private insurance companies cover and how much they can charge.
