The Patient Protection and Affordable Care Act (ACA), or “Obamacare” for short, a piece of legislation birthed in controversy and plagued by a difficult rollout, is still poorly understood and received by many Americans. Some have a vague idea of what is in the law, but very little comprehension of how the various parts were designed to function together or how those parts affect particular individuals. Many also don’t understand the health insurance exchange concept or how to “shop” for insurance that is compliant with the law and still affordable. That process is further complicated by the decision of many states to opt out of building their own state-based health insurance exchanges or implement a largely Obamacare-funded expansion of Medicaid to cover the uninsured who don’t make enough to purchase ACA-compliant plans and aren’t Medicaid-eligible under current state-specific criteria. Due to the relative youth of the law, its initial effects – on individuals/patients, hospitals, physicians, states, and everyone’s wallets – are still being recorded and decoded. After reading the assigned articles, write a position paper about what you learned about the law. Please be sure to respond to the following questions in your paper
What are the legal bases given by the SCOTUS opinion, supporting Congress’ power to pass the law? Explain.
Do you think anything is missing from the law, or should not have been included? Explain.
Explain how the indirect scheme proposed by the law proposes to bring down costs and improve quality of care. 
Can the legislation achieve that goal, in view of the observed impacts and effects of the law to date on states and their citizens? Why or why not? Explain.
How do you think the changes in healthcare delivery and reimbursement brought on by Obamacare, in conjunction with the widespread use of EHRs and the growing capacity for EHRs to meaningfully exchange health information between providers/practices/hospitals and federal agencies, will impact or change the health information manager’s role? Explain
