The Cigna Group is an American multinational for-profit managed healthcare and insurance company based in Bloomfield, Connecticut.

In October 1871, the great Chicago Fire burned for two days, destroyed 2,000 acres, and left 100,000 people in Illinois homeless.

[26] In September 2020, Cigna rebranded its health services portfolio under the name Evernorth, which included Express Scripts, Accredo, and eviCore.

Additional Cigna Global Health Benefits operations are located in Visalia, California, and Greenock, Scotland and Shanghai, China and Antwerp, Belgium.

CGHB global health plans typically include medical, dental, behavioral and disability, as well as business travel and life components.

Expatriates are defined as employees of multinational companies working outside their home country on short or long-term international assignments.

[33] CGHB maintains its own, in-house international claims platform, and offers a network of physicians and hospitals for its members (including 550,000 in the U.S. and more than 141,000 outside the U.S.).

On February 9, 2005, Cigna elected to adopt in the fourth quarter of 2004 fair value accounting for its stock options in accordance with SFAS No.

[35] In 2008, the head of Cigna's public relations, Wendell Potter, resigned, becoming a whistleblower who gave testimony in 2009 to the U.S. Senate Committee on Commerce, Science and Transportation in favor of reform of the health care industry.

"[38] In December 2007, Cigna refused to pay for a liver transplant of a California teenage girl, Nataline Sarkisyan, coming under scrutiny as a result.

[42] The UK newspaper Guardian in their Esc and Ctrl videoblog about control of the Internet by corporations, documented the incident with Nataline Sarkisyan and the former vice president of Cigna talking about astroturfing, the practice of creating fake blogs by interested groups, e.g. health insurance companies, to push claims that are profitable for said company into media, e.g. dismissing universal health care.

[47] In November 2020, investors sued Cigna's CEO and board alleging that they had used "black-ops-style" tactics to "blow up" the potential merger with Anthem in 2017.

One pension fund accused Cigna CEO David Cordani of seeking to poison the deal after he had failed to secure the top post in the resulting company.

[49] In January 2010, Cigna received the JD Power award for customer service for all of its call centers for the fourth time in a row.
