UnitedHealth Group says it is cooperating with federal criminal and civil investigations involving its market-leading Medicare business.
The health care giant said Thursday that it had contacted the Department of Justice after reviewing media reports about investigations into certain elements of its business.
“(UnitedHealth) has a long record of responsible conduct and effective compliance,” the company said in a Securities and Exchange Commission filing.
Earlier this year, The Wall Street Journal said federal officials had launched a civil fraud investigation into how the company records diagnoses that lead to extra payments for its Medicare Advantage, or MA, plans. Those are privately run versions of the government’s Medicare coverage program mostly for people ages 65 and over.
The company’s UnitedHealthcare business covers more than 8 million people as the nation’s largest provider of Medicare Advantage plans. The business has been under pressure in recent quarters due to rising care use and rate cuts.
The Journal said in February, citing anonymous sources, that the probe focused on billing practices in recent months.
The paper has since said that a federal criminal health care-fraud unit was investigating how the company used doctors and nurses to gather diagnoses that bolster payments.
UnitedHealth said in the filing Thursday that it "has full confidence in its practices and is committed to working cooperatively with the Department throughout this process."
UnitedHealth Group Inc. runs one of the nation's largest health insurance and pharmacy benefits management businesses. It also operates a growing Optum business that provides care and technology support.
UnitedHealth raked in more than $400 billion in revenue last year to come in third in the Fortune 500 list of biggest U.S. companies. Its share price topped $630 last fall to reach a new all-time high.
But the stock has mostly shed value since December, when UnitedHealthcare CEO Brian Thompson was fatally shot in midtown Manhattan on his way to the company’s annual investor meeting. A suspect, Luigi Mangione, has been charged in connection with the shooting.
In April, shares plunged some more after the company cut its forecast due to a spike in health care use. A month later, former CEO Andrew Witty resigned, and the company withdrew its forecast entirely, saying that medical costs from new Medicare Advantage members were higher than expected.
The stock price was down more than 3%, or $10.73, to $281.78 Thursday afternoon. That represents a 55% drop from the all-time high it hit in November. Broader indexes were mixed.
UnitedHealth will report its second-quarter results next Tuesday.

KAMPALA, Uganda (AP) — Uganda’s presidential election was plagued by widespread delays Thursday in addition to a days-long internet shutdown that has been criticized as an anti-democratic tactic in a country where the president has held office since 1986.
Some polling stations remained closed for up to four hours after the scheduled 7 a.m. start time due to “technical challenges," according to the nation's electoral commission, which asked polling officers to use paper registration records to ensure the difficulties did not “disenfranchise any voter.”
President Yoweri Museveni, 81, faces seven other candidates, including Robert Kyagulanyi, a musician-turned-politician best known as Bobi Wine, who is calling for political change.
The East African country of roughly 45 million people has 21.6 million registered voters. Polls are expected to close at 4 p.m. Thursday, according to the electoral commission. Results are constitutionally required to be announced in 48 hours.
Impatient crowds gathered outside polling stations expressing concerns over the delays Thursday morning. Umaru Mutyaba, a polling agent for a parliamentary candidate, said it was “frustrating” to be waiting outside a station in the capital Kampala.
“We can’t be standing here waiting to vote as if we have nothing else to do," he said.
Wine alleged there was electoral fraud occurring, noting that biometric voter identification machines were not working at polling places and claiming there was “ballot stuffing.”
“Our leaders, including Deputy President for Western Region, arrested. Many of our polling agents and supervisors abducted, and others chased off polling stations,” Wine wrote in a post on social media platform X.
Museveni told journalists he was notfied biometric machines were inoperable at some stations and he supported the electoral body's decision to revert to paper registration records. He did not comment on the allegation of fraud.
Ssemujju Nganda, a prominent opposition figure and lawmaker seeking reelection in Kira municipality, told The Associated Press he had been waiting in line to vote for three hours.
Nganda also noted biometric machines were malfunctioning, in addition to the late arrival of balloting materials, and predicted the delays likely would lead to apathy and low turnout in urban areas where the opposition has substantial support.
"It’s going to be chaos,” he said Thursday morning.
Nicholas Sengoba, an independent analyst and newspaper columnist, said delays to the start of voting in urban, opposition areas favored the ruling party.
Uganda has not witnessed a peaceful transfer of presidential power since independence from British colonial rule six decades ago.
Museveni has served the third-longest term of any African leader and is seeking to extend his rule into a fifth decade. Some critics say removing him through elections remains difficult, but the aging president’s authority has become increasingly dependent on the military led by his son, Muhoozi Kainerugaba.
Museveni and Wine are reprising their rivalry from the previous election in 2021, when Wine appealed to mostly young people in urban areas. With voter turnout of 59%, Wine secured 35% of the ballots against Museveni’s 58%, the president’s smallest vote share since his first electoral campaign three decades ago.
The lead-up to Thursday's election produced concerns about transparency, the possibility of hereditary rule, military interference and opposition strategies to prevent vote tampering at polling stations.
Uganda's internet was shut down Tuesday by the government communications agency, which cited misinformation, electoral fraud and incitement of violence. The shutdown has affected the public and disrupted critical sectors such as banking.
There has been heavy security leading up to voting, including military units deployed on the streets this week.
Amnesty International said security forces are engaging in a “brutal campaign of repression,” citing a Nov. 28 opposition rally in eastern Uganda where the military blocked exits and opened fire on supporters, killing one person.
Museveni urged voters to come out in large numbers during his final rally Tuesday.
“You go and vote, anybody who tries to interfere with your freedom will be crushed. I am telling you this. We are ready to put an end to this indiscipline,” he said.
The national electoral commission chairperson, Simon Byabakama, urged tolerance among Ugandans as they vote.
“Let us keep the peace that we have,” Byabakama said late Wednesday. “Let us be civil. Let us be courteous. Let’s be tolerant. Even if you know that this person does not support (your) candidate, please give him or her room or opportunity to go and exercise his or her constitutional right."
Authorities also suspended the activities of several civic groups during the campaign season. That Group, a prominent media watchdog, closed its office Wednesday after the interior ministry alleged in a letter that the group was involved in activities “prejudicial to the security and laws of Uganda.”
