Which of the following is NOT considered a managed care organization?

The Medical Information Bureau (MIB) is not considered a managed care organization because its primary function is to serve as a centralized resource for health and life insurance companies to assess the medical history of applicants. MIB collects and maintains records of individuals' health-related information but does not provide health care services, coordinate care, or manage provider networks, which are the hallmarks of managed care organizations.

On the other hand, Health Maintenance Organizations (HMOs), Preferred Provider Organizations (PPOs), and Exclusive Provider Organizations (EPOs) are all types of managed care organizations that focus on providing health care services to members while controlling costs through networks of providers and negotiated prices. These organizations actively manage patient care, including establishing provider networks and coordinating services to ensure members receive appropriate and cost-effective care. The MIB does not engage in these activities, solidifying why it stands apart from managed care organizations.
