Supporters of a public plan, such as Washington Post columnist E. J. Dionne, argue that many places in the United States have monopolies in which one company, or a small set of companies, control the local market for health insurance. Economist and New York Times columnist Paul Krugman also wrote that local insurance monopolies exist in many of the smaller states, accusing those who oppose the idea of a public insurance plan as defenders of local monopolies. He also argued that traditional ideas of beneficial market competition do not apply to the insurance industry given that insurers mainly compete by risk selection, claiming that "[t]he most successful companies are those that do the best job of denying coverage to those who need it most."
Another distinction between plans that can change the rates you pay, is the type of network the plan uses. Depending on whether the plan is a PPO, HMO, EPO or POS plan, consumers will have access to the health care providers managed in different ways. HMOs tend to be the most restrictive about which doctors you can see and what you must do to see them. This usually means that the insurers save on your cost of care and thereby provide lower premiums.
Individual and family health insurance plans can help cover expenses in the case of serious medical emergencies, and help you and your family stay on top of preventative health-care services. Having health insurance coverage can save you money on doctor's visits, prescriptions drugs, preventative care and other health-care services. Typical health insurance plans for individuals include costs such as a monthly premium, annual deductible, copayments, and coinsurance.
