What is the full name of the program commonly known as Obamacare?

The full name of the program commonly referred to as Obamacare is indeed the Patient Protection and Affordable Care Act (PPACA). This legislation was enacted in March 2010 with the primary aim of expanding access to health insurance, controlling healthcare costs, and improving the healthcare delivery system in the United States.

The acronym "Obamacare" specifically refers to the law often associated with President Barack Obama, who championed the reform. The term encompasses a range of provisions intended to protect consumers, such as prohibiting denial of coverage due to pre-existing conditions and allowing young adults to stay on their parents' insurance plans until age 26.

While the Affordable Care Act (ACA) is often used interchangeably with PPACA, it is technically a shorthand reference that omits the "Patient Protection" aspect. The other options, such as Health Care Reform Act and Public Health Act, do not accurately describe this specific legislation and are not recognized titles for the law in question.
