10 Biggest HMOs in USA

The 10 biggest HMOs in USA are among the companies that strive to reduce your out-of-pocket medical costs and monthly premiums. HMO stands for Health Maintenance Organization, which is a medical insurance group providing health services for a fixed annual fee or a monthly premium. A HMO is a prepaid health plan which takes care of all the health requirements of an individual from an in-network provider.

Health maintenance organizations require that you select a primary care physician (PCP). A PCP is a personal doctor who provides all basic healthcare services and guides a person to a specialist if there is a need. The doctors serving under an HMO contract treat patients in accordance with the HMO’s guidelines. HMOs are ideal for employees who would like one doctor to coordinate all their medical care at predictable costs. They do not involve hassles of filing up claim forms; you just need to present a card at the doctor’s office or hospital.

Employers with 25 or more employees are required to offer certified HMO options to their employees under the Health Maintenance Organization Act of 1973.
