The American Health Care Act (AHCA) is a legislative proposal that aimed to repeal and replace the Affordable Care Act (ACA), also known as Obamacare. Introduced in 2017, the AHCA sought to significantly alter the U.S. healthcare landscape by reducing government involvement in health insurance, eliminating mandates for individuals to purchase insurance, and restructuring Medicaid funding, which would impact millions of Americans' access to healthcare services.
