Overview
Aetna is an American health insurance and managed-care brand whose business centers on medical coverage, employer-sponsored benefits, government health programs, and related healthcare administration. Its portfolio has included traditional insurance and consumer-directed plans as well as dental, pharmacy-benefit, behavioral-health, disability, and long-term-care services. Aetna primarily serves the United States through employer-paid or employer-supported benefit programs, individual and family coverage, Medicare products, Medicaid-related plans, and administrative services for institutional customers. The brand traces its corporate lineage to insurance activity in Hartford, Connecticut, during the early nineteenth century. The Aetna name was adopted from Mount Etna, historically regarded as one of Europe’s most active volcanoes. A separate Aetna Life Insurance Company was incorporated in 1853, initially focusing on life insurance and annuities rather than modern medical insurance. During the nineteenth and early twentieth centuries, the company expanded into accident, liability, group, automobile, and other insurance lines. Health insurance became an increasingly important part of the business, and the company later moved toward managed care and administration of medical benefits. Aetna underwent substantial restructuring in the 1990s and 2000s. It acquired U.S. Healthcare in 1996, adopted the Aetna Inc. name, and subsequently bought NYLCare Health Plans and Prudential HealthCare. These transactions made Aetna one of the largest American health-benefits companies, but rapid expansion was followed by a major turnaround under chief executive John Rowe. The company raised premiums, exited less profitable markets, reduced its membership base, and sold or separated non-health businesses. Later acquisitions, including Coventry Health Care and Prodigy Health Group, strengthened its government-program and third-party-administration capabilities. Aetna announced a proposed acquisition of Humana in 2015, but the transaction was blocked by a federal judge in 2017 on competition grounds and was formally abandoned that year. CVS Health announced a separate acquisition of Aetna in December 2017 and completed it on November 28, 2018. Aetna’s public-company ticker was delisted after completion, and the brand became part of CVS Health’s integrated healthcare system, alongside retail pharmacies, pharmacy-benefit management, and other healthcare services. Mark Bertolini left the chief executive role around the transaction, while Karen S. Lynch led Aetna operations before becoming CVS Health’s chief executive in 2020. Aetna continues to operate as a CVS Health health-insurance business and brand. Its network and offerings span medical professionals, hospitals, dental providers, pharmacy-benefit users, employers, Medicare members, and Medicaid populations, although the exact products and geographic availability vary by state and plan. In 2021, CVS Health announced that Aetna would return to individual Affordable Care Act exchange offerings beginning in 2022. The brand’s present positioning is that of a broad U.S. health-benefits platform combining insurance coverage with care-management, pharmacy, behavioral-health, dental, and government-program capabilities.
History
Aetna’s corporate history begins in Hartford, Connecticut, where the Aetna Fire Insurance Company developed during the early nineteenth century. Thomas Kimberly Brace was a principal founder and early president, while Henry Leavitt Ellsworth succeeded him as president. The company’s charter was broadened to permit life insurance and annuity underwriting, and on May 28, 1853, the annuity department was separated and incorporated as the Aetna Life Insurance Company under Eliphalet Bulkeley. The company name referred to Mount Etna, whose volcanic reputation provided a distinctive identity. Aetna expanded rapidly during the Civil War era. It introduced dividend-paying life policies, built a national agency system, appointed an actuary, and replaced installment-style premium arrangements with cash premiums. By the late nineteenth century, its insurance activities included accident coverage, and in 1899 it began offering health insurance. During the early twentieth century, Aetna added employers’ liability, workers’ compensation-related coverage, engineering and inspection services, automobile insurance, group life insurance, and various property and marine products. These lines established Aetna as a diversified insurer rather than a single-product health company. The company continued expanding through the twentieth century. It acquired or invested in insurance businesses in Canada, Australia, Chile, Europe, and Asia, and its shares began trading on the New York Stock Exchange in 1968. It also developed pension administration and other employee-benefit capabilities. In 1996, Aetna sold its property-and-casualty subsidiary to Travelers, acquired U.S. Healthcare, and changed its corporate name to Aetna Inc. Acquisitions of NYLCare Health Plans in 1998 and Prudential HealthCare in 1999 significantly increased its health-plan membership and made it one of the largest U.S. providers of health benefits. The scale of the late-1990s expansion created operational and financial pressures. Under John Rowe, beginning in 2000, Aetna pursued a turnaround that included large job reductions, premium increases, technology investment, discontinuation of unprofitable accounts, and withdrawal from selected markets. Membership declined substantially as the company narrowed its focus. Aetna also sold financial-services and international operations to ING and concentrated on health and group benefits. In the same period, the company apologized for its nineteenth-century issuance of policies covering enslaved people. During the 2000s and 2010s, Aetna rebuilt through targeted acquisitions and partnerships. It bought Schaller Anderson, later acquired Prodigy Health Group and its Meritain Health business, formed Innovation Health with Inova Health System, and acquired Coventry Health Care for $5.7 billion. Medicaid operations were increasingly presented under the Aetna Better Health name. Aetna also formed Banner|Aetna with Banner Health. In 2015 it proposed a $37 billion acquisition of Humana, but a federal court blocked the transaction in January 2017 and the companies ended the deal in February after further legal opposition. CVS Health announced its acquisition of Aetna in December 2017. The deal replaced a previously announced plan to move Aetna’s headquarters to New York, with Hartford remaining important to the company. Completion occurred on November 28, 2018; Aetna’s NYSE ticker was delisted and the company became a CVS Health subsidiary. Karen Lynch assumed operational leadership of Aetna during the transaction period and was later appointed CVS Health chief executive in 2020. In 2021, CVS Health announced a renewed Aetna presence on individual ACA exchanges from 2022. Today, Aetna operates within CVS Health’s wider healthcare platform, serving commercial, government, dental, pharmacy-benefit, behavioral-health, and related healthcare markets in the United States.
