A Health Maintenance Organization (HMO) is a company that offers an insurance-like product to people who enroll with the company.
HMOs typically offer their enrollees a defined set of basic health care services for a prepaid, fixed fee. These services include hospital, physician, and other professional health care services.
To receive care that will be paid for by the HMO, members usually must select a network primary care physician who provides for all of the member's primary medical care. This physician also acts as a "gatekeeper" who is responsible for referrals and access to specialists and other services.
Most HMOs limit patients' out-of-pocket expenses to small co-payments.
