How Health Insurance Works

Health care in the United States can be very expensive. A single doctor’s office visit may cost several hundred dollars and an average three-day hospital stay can run tens of thousands of dollars (or even more) depending on the type of care provided. Most of us could not afford to pay such large sums if we get sick, especially since we don’t know when we might become ill or injured or how much care we might need. Health insurance offers a way to reduce such costs to more reasonable amounts. The way it typically works is that the consumer (you) pays an up front premium to a health insurance company and that payment allows you to share “risk” with lots of other people (enrollees) who are making similar payments.

Since most people are healthy most of the time, the premium dollars paid to the insurance company can be used to cover the expenses of the (relatively) small number of enrollees who get sick or are injured. Insurance companies, as you can imagine, have studied risk extensively, and their goal is to collect enough premium to cover medical costs of the enrollees. There are many, many different types of health insurance plans in the U.S. and many different rules and arrangements regarding care.
