Overview
Amerigroup is a United States health insurance and managed-care brand serving people enrolled in government-sponsored health programs. Its principal populations have included Medicaid beneficiaries, children covered through the Children's Health Insurance Program, low-income adults and families, seniors, people with disabilities, and beneficiaries eligible for both Medicare and Medicaid. The brand operates through state and federal program contracts, provider networks, benefit administration, primary-care coordination, utilization management, and other care-management services rather than through a conventional commercial insurance model alone. The business began in 1994 as AMERICAID Community Care, with an initial focus on children, mothers, and pregnant women enrolled in Medicaid. It became a publicly traded corporation in November 2001. Amerigroup expanded into Medicare Advantage in 2006, initially emphasizing special-needs plans for people eligible for both Medicare and Medicaid, and added traditional Medicare Advantage operations in 2007. Its government-program portfolio has included Medicaid managed care, CHIP, Medicare Advantage, dual-eligible special-needs plans, and products directed at specific low-income populations such as Supplemental Security Income recipients and families receiving assistance through Medicaid-related programs. In July 2012, WellPoint, now known as Elevance Health, agreed to acquire Amerigroup Corporation for $4.9 billion. After the transaction, Amerigroup became part of a larger national health-insurance group while retaining use as a public-program brand in selected markets. The brand's geographic presence, plan names, benefits, provider networks, and contractual responsibilities vary by state because Medicaid and related programs are administered through state-specific rules and procurement arrangements. The reference material describes Amerigroup as serving 7.7 million seniors, people with disabilities, low-income families, other state- and federally sponsored beneficiaries, and federal employees across 26 states. In July 2023, a name transition to Wellpoint was announced for six states, with implementation beginning in January 2024. This indicates a continuing brand-portfolio realignment within Elevance Health rather than a simple nationwide disappearance of the Amerigroup identity. Amerigroup has also supported community initiatives through the Amerigroup Foundation, employee volunteer programs, and an advisory board focused on seniors and people with disabilities. Its history includes a major federal Medicaid-fraud case arising from allegations that Illinois Medicaid applicants with costly medical conditions, including pregnant women, were improperly discouraged or excluded from enrollment.
History
Amerigroup began in 1994 under the name AMERICAID Community Care. Its early mission centered on managed health care for children, mothers, and pregnant women enrolled in Medicaid. This placed the company within the expanding United States market for publicly financed managed care, in which state governments contract with private health plans to organize benefits, provider access, and care coordination for eligible populations. The company became publicly traded in November 2001. During the early 2000s, its Illinois operations became the subject of a federal Medicaid-fraud case. A former executive, Cleveland Tyson, provided evidence alleging that the company had sought to enroll healthier beneficiaries while discouraging or excluding pregnant women and other people expected to require more expensive care. In October 2006, a federal jury found Amerigroup liable for $48 million in damages, which were trebled under applicable law. In March 2007, an additional penalty exceeding $190 million was imposed in relation to 18,000 allegedly false claims. Following appeals, Amerigroup agreed in July 2008 to settle the matter for $225 million. Tyson received $56 million under qui tam whistleblower provisions. Amerigroup expanded beyond Medicaid during the second half of the 2000s. In 2006 it entered Medicare Advantage, initially serving low-income people eligible for both Medicare and Medicaid through special-needs plans. In 2007 it began operating traditional Medicare Advantage plans. Its public-program portfolio subsequently covered Medicaid, CHIP, and Medicare, with products aimed at groups including Supplemental Security Income recipients, low-income children and mothers, uninsured adults and parents, and dual-eligible Medicare and Medicaid beneficiaries. The company also developed organizational programs related to its public-service orientation. In 2007 it created a National Advisory Board focused on seniors and people with disabilities. The board included community advocates, health-care experts, and academics and was convened by Lex Frieden, a disability-rights leader associated with the Americans with Disabilities Act. Its work addressed the design of health-care infrastructure and services for older adults and people with disabilities. The Amerigroup Foundation supported access to care, children and family health, and community improvement, while the company's Community Volunteers program provided employees with paid time to volunteer. On July 9, 2012, WellPoint, Inc. entered into an agreement to acquire Amerigroup Corporation for $4.9 billion. WellPoint later changed its corporate name to Anthem, Inc., and subsequently became Elevance Health, Inc. Amerigroup therefore shifted from an independent public company into a brand within a larger health-insurance organization. Its operations remained closely connected to state contracts, so its presence and offerings continued to differ across jurisdictions. In March 2020, Amerigroup notified Grays Harbor Community Hospital and Harbor Medical Group that their relationship would terminate effective June 28 of that year. In July 2023, a transition from the Amerigroup name to Wellpoint was announced in six states, beginning in January 2024. The rebranding reflects ongoing portfolio changes under Elevance Health; the Amerigroup name may nevertheless continue in selected government-program markets or historical references. Detailed current state-by-state availability, executive leadership, and corporate headquarters are not established by the supplied reference material.
