The Optum brand was created in 2011 to unify the group's health services business. Optum focuses on "making the health system work better for everyone" and by serving as UnitedHealth's technology-focused arm which aims to develop patient-focused tools supporting insurance transparency and incentivizing patient-directed healthy lifestyles.

Health insurance plans
As of 2018[update], UnitedHealthcare offers commercial group health insurance plans across the United States under several product names with different offerings.:13 UnitedHealthcare Select is exclusive provider organization (EPO) with no coverage for out-of-network providers:2 while UnitedHealthcare Select Plus is a preferred provider organization (PPO).
UnitedHealthcare Navigate, Charter, and Compass require a primary care physician referral to see a specialist meaning that they are more restrictive managed care plans, similar to point of service plans.
UnitedHealthcare negotiates with providers in periodic contract negotiations; contracts may be discontinued from time to time. High-profile contract disputes can span provider networks across the nation, as in the case of a 2018 dispute with a major emergency room doctor group Envision Healthcare.
Maintaining up-to-date provider directories is necessary as CMS can fine insurers with outdated directories. As a condition of participation, UnitedHealthcare requires that providers notify them of changes, but also has a Professional Verification Outreach program to proactively request information from providers. However, providers are burdened by having to maintain their information with multiple networks (e.g., competitors to UnitedHealthcare). The total cost of maintaining these directories is estimated at $2.1b annually, and a blockchain initiative began in 2018 to share the directory.
In 1974, Richard Taylor Burke founded Charter Med Incorporated, a Minnetonka, Minnesota-based privately held company. In 1977, UnitedHealthCare Corporation was created to reorganize the company and become the parent company of Charter Med. UnitedHealthCare’s charter was to manage the newly created Physicians Health Plan of Minnesota, an early health management organization.

The Tucson business was sold to Cigna. Also in December 2005, UnitedHealth Group acquired John Deere Health Care.
In March 2007, UnitedHealth Group signed a definitive agreement to acquire Sierra Health Services Inc. for $2.6 billion. Sierra provided health benefits and services to 310,000 members in Nevada and another 320,000 people in senior and government programs throughout the United States.

Health and government
In 2010, UnitedHealth Group spent more than $1.8 million on lobbying activities to work to achieve favorable legislation, and hired seven different lobbying firms to work on its behalf. In addition, its corporate political action committee or PAC, called United for Health, spent an additional $1 million on lobbying activities in 2010.
QSSI, a subsidiary of UnitedHealth Group, is one of the 55 contractors hired by United States Department of Health and Human Services to work on the HealthCare.gov web site
Health Care reform
Through 2010 and into 2011, UnitedHealth senior executives have been meeting monthly with executives of leading health insurers to limit the effect of the health care reform law.
In 2006, the Securities and Exchange Commission (SEC) began investigating the conduct of UnitedHealth Group's management and directors, for backdating of stock options. Investigations were also begun by the Internal Revenue Service and prosecutors in the U.S. attorney's office for the Southern District of New York, who subpoenaed documents from the company. The investigations came to light after a series of probing stories in the Wall Street Journal in May 2006, discussing apparent backdating of hundreds of millions of dollars' worth of stock options by UHC management. The backdating apparently occurred with the knowledge and approval of the directors, according to the Journal. Major shareholders have filed lawsuits accusing former New Jersey governor Thomas Kean and UHC's other directors of failing in their fiduciary duty. On October 15, 2006, CEO William W. McGuire was forced to resign, and relinquish hundreds of millions of dollars in stock options. On December 6, 2007, the SEC announced a settlement under which McGuire will repay $468 million, as a partial settlement of the backdating prosecution. Legal actions filed by the SEC against UnitedHealth Group itself are still pending.
In June 2006, the American Chiropractic Association filed a national class action lawsuit against the American Chiropractic Network (ACN), which is owned by UnitedHealth Group and administers chiropractic benefits, and against UnitedHealth Group itself, for alleged practices in violation of the federal Racketeer Influenced and Corrupt Organizations Act (RICO).
OptumInsight earlier known as Ingenix
In February 2008, New York State Attorney General Andrew M. Cuomo announced an industry-wide investigation into a scheme by health insurers to defraud consumers by manipulating reasonable and customary rates. The announcement included a statement that Cuomo intended "to file suit against Ingenix, Inc., its parent UnitedHealth Group, and three additional subsidiaries." Cuomo asserted that his investigation found that rates found in a database of health care charges maintained by Ingenix were lower than what he determined was the actual cost of certain medical expenses. Cuomo said this inappropriately allowed health insurance companies to deny a portion of provider claims, thereby pushing costs down to members. 
On January 13, 2009, Ingenix announced an agreement with the New York State attorney settling the probe into the independence of the health pricing database. Under the settlement, UnitedHealth Group and Ingenix would pay $50 million to finance a new, non-profit entity that would develop a new health care pricing database. Ingenix would discontinue its medical pricing databases when the new entity makes its product available. The company acknowledged the appearance of a conflict of interest, but admitted no wrongdoing.
On January 15, 2009, UnitedHealth Group announced a $350 million settlement of three class action lawsuits filed in Federal court by the American Medical Association, UnitedHealth Group members, healthcare providers, and state medical societies for not paying out-of-network benefits. This settlement came two days after a similar settlement with Cuomo.
On October 27, 2009, Cuomo announced the creation of FAIR Health, the independent, non-profit organization that will develop a nationwide database for consumer reimbursement, as well as a website where consumers will be able to compare prices before they choose doctors. To fund FAIR Health, the Attorney General's office secured nearly $100 million from insurers such as Aetna, UnitedHealth Group, and Anthem.
Options backdating investigations and lawsuits
In 2006, the SEC began investigating the conduct of UnitedHealth Group's management and directors, including Dr. McGuire, as did the Internal Revenue Service and prosecutors in the U.S. attorney's office for the Southern District of New York, who have subpoenaed documents from the company.
The investigations came to light after a series of probing stories in the Wall Street Journal in March 2006, discussing the apparent backdating of hundreds of millions of dollars' worth of stock options—in a process called options backdating—by UnitedHealth Group management. The backdating apparently occurred with the knowledge and approval of the directors, according to the Journal. Major shareholders have filed lawsuits accusing former New Jersey governor Thomas Kean and UnitedHealth Group's other directors of failing in their fiduciary duty.
Resignation of McGuire
On October 15, 2006, it was announced that Dr. McGuire would step down immediately as chairman and director of UnitedHealth Group, and step down as CEO on December 1, 2006, due to his involvement in the employee stock options scandal. Simultaneously, it was announced that he would be replaced as CEO by Stephen Hemsley, who has served as President and COO and is a member of the board of directors. McGuire's exit compensation from UnitedHealth, expected to be around $1.1 billion, would be the largest golden parachute in the history of corporate America.
McGuire's compensation became controversial again on May 21, 2009, when Elizabeth Edwards, speaking on The Daily Show, used it to support her argument for a public alternative to commercial insurance. Edwards stressed the importance of restoring competition in health insurance markets noting that at one point, "the President of UnitedHealth made so much money, that one of every $700 that was spent in this country on health care went to pay him." Since estimates of McGuire's 2005 compensation range from $59,625,444 to $124.8 million, and the revenue of UnitedHealth Group was then $71 billion, it is therefore possible that Mrs. Edwards may have meant that one of every $700 that was spent on UnitedHealth Group premiums went to pay McGuire.
McGuire's settlement with SEC
On December 6, 2007, the SEC announced a settlement under which McGuire was to repay $468 million, including a $7 million civil penalty, as a partial settlement of the backdating prosecution. He was also barred from serving as an officer or director of a public company for ten years. This was the first time in which the little-used "clawback" provision under the Sarbanes-Oxley Act was used against an individual by the SEC. The SEC continued its investigations even after it in 2008 settled legal actions against both UnitedHealth Group itself and its former general counsel.
Medicare overbilling lawsuit
A whistleblower lawsuit, filed in 2011, charges UnitedHealth Group's data analytics division with assisting in defrauding Medicare by boosting risk adjustment scores from Medicare Advantage companies. The suit alleges that UnitedHealth Group subsidiary Ingenix (now OptumInsight) "defrauded the United States of hundreds of millions — and likely billions — of dollars." Former UnitedHealth executive Benjamin Poehling brought the suit under the False Claims Act. The government said it would proceed on claims against two health care companies, UnitedHealth and its Texas subsidiary WellMed Medical Management. In February 2017, a federal judge unsealed the suit after the Department of Justice announced it would join the case.
Policy Research Org. ownership
The Lewin Group is a policy research and consulting firm that provides economic analysis of health care and human services issues and policies. The organization has existed for about 40 years and has maintained a nonpartisan reputation through its many ownership changes that have occurred over that time. The Lewin Group was purchased in 2007 by Ingenix, a subsidiary of UnitedHealth Group, but alleges editorial and analytical "independence" from UnitedHealth Group, its parent company. The Lewin Group discloses its ownership in its reports and on its web site. While the Lewin Group does not advocate for or against any legislation, both Democratic and Republican politicians frequently cite the firm's studies to argue for and against various U.S. healthcare reform proposals. For example, Democratic Senator Ron Wyden uses Lewin Group estimates to cite the feasibility of his Healthy Americans Act. Former U.S. Representative Eric Cantor, the former House Republican Whip, has referred to the organization as "the nonpartisan Lewin Group" in arguing against government-funded health insurance proposals. Recently, several Lewin studies have been used to argue both for and against the inclusion of a public option in national health reform. Lewin clients who often cite its findings include The Commonwealth Fund which recently held up a Lewin study it commissioned to advocate for a public plan. The report showed that legislative proposals would achieve nearly universal coverage and "estimated that a public plan could offer small businesses insurance that is at least 9 percent cheaper than current small-business policies." However, The Lewin Group has acknowledged that clients sometimes choose not to publicize the results of studies they have commissioned. Indeed, Lewin Group Vice President John Sheils told the Washington Post "sometimes studies come out that don't show exactly what the client wants to see. And in those instances, they have [the] option to bury the study."
UnitedHealth Group has two foundations, the United Health Foundation and UnitedHealthcare Children’s Foundation which were formed in 1999. Since established by UnitedHealth Group in 1999 as a not for profit private foundation, the United Health Foundation has committed more than $170 million to improve health and health care.
