Managed Care Organizations (MCOs) are health care systems that aim to provide quality care while controlling costs. They coordinate services for members through a network of doctors, hospitals, and other providers. MCOs often use strategies like preventive care and wellness programs to keep patients healthy and reduce the need for expensive treatments. Members of MCOs typically pay a monthly premium and may have lower out-of-pocket costs when using in-network providers. These organizations can include various types, such as Health Maintenance Organizations (HMOs) and Preferred Provider Organizations (PPOs), each with different rules regarding provider access and payment structures.
