Health insurance plans come in more flavors than gelato. But luckily for sanity-loving people everywhere, they can all be sorted into four broad categories: indemnity plans (also called fee-for-service plans), point-of-service plans, health maintenance organizations (HMOs), and preferred provider organizations (PPOs). The first two flavors give you, the consumer, lots of options, but at a higher cost. The second two are considered managed care, so you have fewer choices, but the plans tend to be less expensive. Regardless of which plan you choose, health insurance is there to help you cover the potentially extreme (and sudden) costs of health care in case of emergency, or more than band-aid-requiring illness. In addition, if you have health insurance, you are more likely to get routine and preventive care that helps stave off major health events.
