Managed Care plans have revolutionized the health insurance industry in past few decades. Indemnity-based health insurance dominated the industry for a significant stretch in the 20th century. However, today, Managed Care plans have the majority of health insurance enrollees. Managed Care plans focus on giving members the highest quality services at the lowest possible costs. A key role in achieving these goals is organizational partnerships between the Managed Care plan and medical entities, such as hospitals, physicians, laboratories, and clinics, which agree to provide a variety of services at a discounted cost. The partnership can reap mutual benefits, as the medical entities receive large amounts of business and the Managed Care plans drive up patient volume and usage.
