Magellan Health
American healthcare services company specializing in managed care for behavioral health, pharmacy, and other special populations.
Last updated August 22, 2026
Overview
Magellan Health is an American for-profit healthcare services company and a subsidiary of Centene Corporation. Its business has centered on managed care and specialty healthcare programs rather than on operating a conventional network of hospitals or selling consumer medical products. Magellan has served health plans, managed care organizations, employers, labor unions, military and government agencies, and third-party administrators. The organization traces its origins to Charter Medical, a psychiatric hospital chain headquartered in Macon, Georgia. Charter Medical expanded through a debt-financed management-led takeover in 1988, but the resulting financial burden contributed to a Chapter 11 bankruptcy filing in 1992. After restructuring and recovery, the company moved its headquarters to Atlanta in 1994. It subsequently acquired a major stake in Green Spring Health Services, a Maryland-based managed care company, and reorganized under the Magellan Health Services name. This transition marked a shift away from its earlier psychiatric-hospital identity toward managed behavioral healthcare and broader specialty services. Magellan expanded its behavioral-health platform in 1997 through the acquisition of Human Affairs International and Merit Behavioral Care. These transactions strengthened its ability to administer behavioral-health benefits and manage services for large institutional customers. In 1999, the company relocated its headquarters to Green Spring's former Columbia, Maryland, headquarters. It later moved to Connecticut in 2004 and then to Arizona in 2014. Over time, Magellan's activities extended beyond behavioral health. Its specialty capabilities included pharmacy benefit management and programs designed for complex, high-need, or otherwise special populations. The company's customers included commercial health plans, public-sector purchasers, employers, unions, and other organizations that outsourced benefit administration, utilization management, care coordination, or specialty clinical programs. The company also went through a period of portfolio reshaping. In 2018, it sold its managed-care division to Molina Healthcare, narrowing the scope of the remaining organization. Centene announced an agreement to acquire Magellan Health for approximately $2.2 billion on January 4, 2021, and completed the transaction on January 4, 2022. Following the acquisition, Magellan operated as part of Centene's broader healthcare-services portfolio. Centene later divested Magellan Rx to Prime Therapeutics and announced the sale of Magellan Specialty Health to Evolvent Health in 2022. Magellan was ranked 390th on the Fortune 500 in 2021. Its present identity is therefore best understood as a specialty healthcare-services platform within Centene, with historical roots in psychiatric hospitals and managed behavioral healthcare and a later focus on specialized benefit-management and clinical-service capabilities.
History
Magellan Health originated as Charter Medical, a psychiatric hospital chain based in Macon, Georgia. The predecessor company underwent a management-led takeover in 1988 that left it carrying significant debt. The financial strain associated with that transaction ultimately led Charter Medical to file for Chapter 11 bankruptcy in 1992. After recovering from bankruptcy, the company relocated its headquarters to Atlanta in 1994. It then acquired a major interest in Green Spring Health Services, a managed-care company headquartered in Columbia, Maryland. The transaction supported a corporate reorganization and a change of name to Magellan Health Services, reflecting the company's movement toward managed healthcare and away from its earlier hospital-chain profile. Magellan deepened its position in behavioral-health management in 1997 by acquiring Human Affairs International and Merit Behavioral Care. These acquisitions expanded its ability to administer behavioral-health benefits and coordinate services for health plans and other institutional purchasers. In 1999, the company moved its headquarters to Green Spring's former headquarters in Columbia, Maryland. Subsequent headquarters relocations took place in Connecticut in 2004 and Arizona in 2014. The company's business model developed around specialty healthcare administration. Its customers included health plans and other managed-care organizations, employers, labor unions, military and governmental agencies, and third-party administrators. Its capabilities encompassed behavioral health, specialty care, pharmacy-related services, and programs for complex or special populations. Rather than relying primarily on direct-to-consumer healthcare sales, Magellan generally operated through institutional contracts and outsourced benefit-management arrangements. A major portfolio change occurred in 2018, when Magellan sold its managed-care division to Molina Healthcare. The divestiture reduced the breadth of the company and placed greater emphasis on its specialty platforms. On January 4, 2021, Centene Corporation announced that it would acquire Magellan Health for approximately $2.2 billion. The transaction closed on January 4, 2022, making Magellan a Centene subsidiary. After the acquisition, Centene continued to adjust the portfolio. In 2022, it divested Magellan Rx to Prime Therapeutics and announced the sale of Magellan Specialty Health to Evolvent Health. These transactions separated major businesses that had been associated with the Magellan name and left the brand's corporate identity closely linked to Centene's specialty healthcare strategy. Magellan was listed at number 390 on the 2021 Fortune 500.
