There is no law called "Obamacare". Its the ACA (Affordable Care Act). Here is the answer to your question. The ACA it not a completely, overtaking healthplan as it relies on states inputs and plans in some facets.
Low-income children get health insurance from a complicated and overlapping web of programs, including CHIP, Medicaid and Obamacare marketplace plans. Each program has different cost sharing and premium requirements, doctor networks and eligibility standards, which can lead to disparities in coverage.
Yet hereís another reality. It turns out that Obamacare didnít achieve the coverage gains everyone had hoped for. About two-fifths of states didnít expand their Medicaid programs. Marketplace enrollment has fallen short of projections. About 28 million Americans remain uncovered.
