What is an HMO?
Health Maintenance Organization (also called an HMO) is one of three managed care health insurance systems in the United States. An HMO is designed to offer financial support and medical treatment to plan members. Some managed care systems don't offer medical treatment themselves. Rather, they offer different levels of financial coverage based on whether you visit in-network or out-of-network care providers. HMOs, on the other hand, have a system of physicians and hospitals that are involved in a specific coverage structure. If you're part of a Health Maintenance Organization, you are only covered if you go to a physician within the HMO network.
