"The Affordable Care Act (ACA), enacted in March 2010, appropriated billions of dollars of mandatory funds to support grant programs and other activities. Specifically, it provided support for three programs focused on expanding access to primary care services for populations that are typically underserved. These three programs are the Health Centers program, the National Health Service Corps (NHSC), and payments to support medical residents training at teaching health centers- outpatient health facilities that primarily provide care to underserved populations. The ACA funds were initially for five years, but funding for these three programs was subsequently extended for two years (i.e., for FY2016 and FY2017) in the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA; P.L. 114-10). The President's FY2018 budget proposes extending funding for these programs for two more years."
