What is the ACA?
ACA—generally referred to as Obamacare—is the health reform legislation passed by the 111th Congress and signed into law by President Barack Obama in March 2010.
The legislation includes a long list of health-related provisions that began taking effect in 2010.
Key provisions are intended to extend coverage to millions of uninsured Americans, to implement measures that will lower health care costs and improve system efficiency, and to eliminate industry practices that include rescission and denial of coverage due to pre-existing conditions.
The ACA requires large employers to provide a qualified level of insurance coverage. This requirement is enforced by the number of full-time equivalent employees (those who work 30 hours per week or more). However, part-time employees are also part of the calculation, as a fraction, and are included in the overall total.
