PPO (Preferred Provider Organization) - A type of insurance plan that offers more extensive coverage for the services of healthcare providers who are part of the plan's network, but still offers some coverage for providers who are not part of the plan's network. PPO plans generally offer more flexibility than HMO plans, but premiums tend to be higher.
Types of Coverage: All of the health plans sold through the Marketplace are offered by private insurance companies and are required to meet minimum requirements. All of the plans are required to cover a comprehensive set of benefits that includes hospital care, doctors’ visits, emergency care, prescription drugs, lab services, preventive care, and rehabilitative services. Before choosing a plan, individuals will be able to see whether their healthcare practitioner participates in the plan’s network (if choosing a network plan). Individuals will be able to choose the plan that best meets their needs and budget. Individuals with low-incomes may instead qualify for free or low-cost coverage through Medicaid or the Children’s Health Insurance Program. 
As per the Constitution of Canada, health care is mainly a provincial government responsibility in Canada (the main exceptions being federal government responsibility for services provided to aboriginal peoples covered by treaties, the Royal Canadian Mounted Police, the armed forces, and Members of Parliament). Consequently, each province administers its own health insurance program. The federal government influences health insurance by virtue of its fiscal powers – it transfers cash and tax points to the provinces to help cover the costs of the universal health insurance programs. Under the Canada Health Act, the federal government mandates and enforces the requirement that all people have free access to what are termed "medically necessary services," defined primarily as care delivered by physicians or in hospitals, and the nursing component of long-term residential care. If provinces allow doctors or institutions to charge patients for medically necessary services, the federal government reduces its payments to the provinces by the amount of the prohibited charges. Collectively, the public provincial health insurance systems in Canada are frequently referred to as Medicare.[15] This public insurance is tax-funded out of general government revenues, although British Columbia and Ontario levy a mandatory premium with flat rates for individuals and families to generate additional revenues - in essence, a surtax. Private health insurance is allowed, but in six provincial governments only for services that the public health plans do not cover (for example, semi-private or private rooms in hospitals and prescription drug plans). Four provinces allow insurance for services also mandated by the Canada Health Act, but in practice there is no market for it. All Canadians are free to use private insurance for elective medical services such as laser vision correction surgery, cosmetic surgery, and other non-basic medical procedures. Some 65% of Canadians have some form of supplementary private health insurance; many of them receive it through their employers.[16] Private-sector services not paid for by the government account for nearly 30 percent of total health care spending.[17]

All regular full-time employees are required to enroll in a retirement plan. Regular part time employee’s enrollment is optional. Employees who are non-US citizens on F-1 or J-1 visas are not eligible for retirement membership. Non-exempt employees are automatically enrolled in the Tennessee Consolidated Retirement System Hybrid (TCRS). TCRS is a defined benefit and contributory plan which requires 5 years of service to vest. Exempt employees have the option to elect the TCRS Hybrid or Optional Retirement Program Hybrid (ORP). The ORP is a defined benefit and contributory plan with no vesting requirements. Both retirement options require a monthly employee contribution of 5%.


Medicare Supplement policies are designed to cover expenses not covered (or only partially covered) by the "original Medicare" (Parts A & B) fee-for-service benefits. They are only available to individuals enrolled in Medicare Parts A & B. Medigap plans may be purchased on a guaranteed issue basis (no health questions asked) during a six-month open enrollment period when an individual first becomes eligible for Medicare.[128] The benefits offered by Medigap plans are standardized.

HMO (Health Maintenance Organization) - Offers healthcare services only with specific HMO providers. Under an HMO plan, you might have to choose a primary care doctor. This doctor will be your main healthcare provider. The doctor will refer you to other HMO specialists when needed. Services from providers outside the HMO plan are hardly ever covered except for emergencies. 
On the whole, uninsured Americans have worse health outcomes; cancers and other deadly diseases, for example, are more likely to be diagnosed at later stages in uninsured people. Uninsured pregnant women use fewer prenatal services and uninsured children and adults are less likely than their insured counterparts to have a primary care doctor whom they trust.
For many Americans, especially those who struggle to make ends meet, living paycheck to paycheck, health insurance may seem like an unnecessary expense. The opposite is true. While there are many smart ways to go about saving money, going without health insurance isn’t one of them. Forgoing coverage isn’t smart, nor will it save you money in the long run. The bottom line? Being uninsured is financially risky.

In January 2013, Representative Jan Schakowsky and 44 other U.S. House of Representatives Democrats introduced H.R. 261, the "Public Option Deficit Reduction Act", which would amend the 2010 Affordable Care Act to create a public option. The bill would set up a government-run health insurance plan with premiums 5% to 7% percent lower than private insurance, with the Congressional Budget Office estimating a reduction in the United States public debt by $104 billion over 10 years.[12]

A 2011 study found that there were 2.1 million hospital stays for uninsured patients, accounting for 4.4% ($17.1 billion) of total aggregate inpatient hospital costs in the United States.[12] The costs of treating the uninsured must often be absorbed by providers as charity care, passed on to the insured via cost-shifting and higher health insurance premiums, or paid by taxpayers through higher taxes.[13]
