"Oz's deep ties to the private healthcare industry make his nomination to lead our nation's current healthcare system totally egregious," said Public Citizen healthcare advocate Eagan Kemp.
The watchdog group Public Citizen said Thursday that lawmakers should reject President-elect Donald Trump's nomination of Medicare privatization advocate Mehmet Oz to lead a key health agency and instead move toward a publicly run single-payer system that would cover all Americans at a lower cost than the status quo.
In a new brief, Public Citizen warned that Medicare privatization efforts—particularly via an expansion of Medicare Advantage plans run by for-profit insurance companies—would likely "move into overdrive" if the Senate confirms Oz as administrator of the Centers for Medicare and Medicaid Services (CMS).
Ahead of his 2022 Senate bid, Oz backed a plan he described as "Medicare Advantage for All," under which privately run plans would cover non-seniors and "all Americans who are not on Medicaid"—effectively eliminating traditional Medicare.
Public Citizen warned such a plan "would mean huge corporate profits while patients continue to struggle to get the healthcare they need," noting that Medicare Advantage plans are notorious for denying necessary care and overbilling the federal government to the tune of tens of billions of dollars per year.
"Policymakers should pass Medicare for All to guarantee care for everyone in the U.S., bring down costs for working families, and generate savings for the country as a whole."
"Further privatizing Medicare would increase healthcare costs systemwide by adding further administrative bloat to our healthcare system," the new brief argues. "Our healthcare system is already made up of thousands of health insurance plans offered by numerous insurers as well as state and federal programs that all play some role in paying for healthcare."
"By spending healthcare resources on corporate profit or administrative waste, privatized Medicare would mean Americans pay even more for healthcare than they already do," the brief adds. "We already spend far more than comparably wealthy countries, over $12,500 per capita, compared with peer nations that are spending around half, per capita."
Oz's plan would also benefit companies in which he has invested tens of millions of dollars, according to financial disclosures.
"Dr. Oz owned between $280,000 and $600,000 in shares in UnitedHealth Group, a major Medicare Advantage insurer, and between $50,000 and $100,000 in shares of CVS Health," Public Citizen noted Thursday, citing the filings.
Eagan Kemp, a healthcare advocate at Public Citizen, said in a statement that Oz's "Medicare Advantage for All" proposal "is dangerous to all patients, especially seniors and people with disabilities, many of whom have not received the care they need under Medicare Advantage."
"Healthcare is a right, not a commodity," said Kemp. "Oz's deep ties to the private healthcare industry make his nomination to lead our nation's current healthcare system totally egregious. Congress should reject Oz's nomination and any proposal to further privatize Medicare."
"Instead," he added, "policymakers should pass Medicare for All to guarantee care for everyone in the U.S., bring down costs for working families, and generate savings for the country as a whole."
Public Citizen's brief came as Oz's nomination faced increasingly close scrutiny from congressional Democrats, who have raised similar concerns about the former television personality's promotion of Medicare Advantage and ties to the private insurance industry.
"As CMS administrator, you would be tasked with overseeing Medicare and ensuring that the tens of millions of seniors that rely on the program receive the care they deserve, including cracking down on abuses by private insurers in Medicare Advantage," a group of Democratic lawmakers led by Sen. Elizabeth Warren (D-Mass.) wrote in a letter to Oz last week. "The consequences of failure on your part would be grave. Billions of federal healthcare dollars—and millions of lives—are at stake."
"Given your financial ties to private insurers, combined with your view that the traditional Medicare program is 'highly dysfunctional' and your advocacy for eliminating it entirely," the lawmakers added, "it is not clear that you are qualified for this critical job."
"Seniors deserve a CMS leader who will protect and strengthen Medicare—not someone like Dr. Oz who wants to privatize this vital and hugely popular program for great personal gain," said the head of Accountable.US.
Dr. Mehmet Oz, the "former daytime television fixture" who U.S. President-elect Donald Trump picked to lead the Centers for Medicare and Medicaid Services, reported "up to $56 million in investments in three companies" with direct CMS interests, the watchdog Accountable.US highlighted Friday.
The celebrity heart surgeon is already under fire for his record of peddling "baseless or wrong" health advice and pushing Medicare Advantage (MA)—an alternative to the government-run program administered by private health insurance companies—on The Dr. Oz Show, as well as his stake in UnitedHealth and CVS Health.
The new Accountable.US report—based on disclosures from Oz's unsuccessful 2022 run against U.S. Sen. John Fetterman (D-Pa.)—adds to conflict of interest concerns and fears that Oz may thwart the Biden administration's new rule intended to rein in privatized Medicare Advantage plans.
"Dr. Oz's conflicts of interest pose a serious threat to seniors' health security."
"In 2022, Oz's 'single biggest healthcare holding' was up to $26 million in Sharecare, a digital health company Oz co-founded that became the 'exclusive in-home care supplemental benefit program' for 1.5 million MA enrollees across 400 MA plans through its CareLinx service in 2022," the watchdog detailed. "By 2023, CareLinx was available to over 2 million MA enrollees. Sharecare was taken private in a $518 million private equity deal in 2024, and it is unknown if Oz still holds a stake."
Nick Clemens, Oz's spokesperson on the Trump transition team, told USA TODAY—which first reported on the Accountable.US findings—that Oz sold his stake in Sharecare but did not address further questions.
The group noted that "in 2022, Oz disclosed holding up to $25 million in Amazon and up to $5 million in Microsoft, which CMS called its 'two primary cloud service providers' in its FY 2025 budget document, which requested over $3.3 billion in information technology funding for the year. Notably, Amazon Web Services hosted 74 million Medicaid records as early as 2017 and the company has been contracted to streamline Healthcare.gov, the federal health insurance portal run by CMS."
Accountable.US "reviewed filings with the Securities and Exchange Commission and was unable to find evidence that Oz sold stocks in Amazon or Microsoft since the 2022 filing," according to USA Today—which found that Oz's stakes could be as high as $26.7 million for Amazon and $6.3 million for Microsoft.
When asked if Oz still owned the stocks in the two tech giants, Trump transition spokesperson Brian Hughes only said that "all nominees and appointees will comply with the ethical obligations of their respective agencies."
Given the nominee's TV and investment history, Accountable.US executive director Tony Carrk declared Friday that "seniors deserve a CMS leader who will protect and strengthen Medicare—not someone like Dr. Oz who wants to privatize this vital and hugely popular program for great personal gain."
"If Dr. Oz and Project 2025 had their way, Medicare as we know it would end, replaced with private insurance plans that cost taxpayers more and leave patients vulnerable to denials of care and higher premiums," Carrk continued, citing the Heritage Foundation-led playbook for the incoming Republican president.
"Dr. Oz's conflicts of interest pose a serious threat to seniors' health security," he added, "but as long as big insurance industry megadonors are happy, President-elect Trump doesn't seem to mind."
While Trump has the power to pick the next CMS administrator, the selection requires Senate confirmation—unless the president-elect works around it to install his most controversial nominees.
On Tuesday, Sen. Elizabeth Warren (D-Mass.) and six colleagues wrote to Oz to express their concerns about his qualifications, "advocacy for the elimination of traditional Medicare," and "deep financial ties to private health insurers."
"As CMS administrator, you would be tasked with overseeing Medicare and ensuring that the tens of millions of seniors that rely on the program receive the care they deserve, including cracking down on abuses by private insurers in Medicare Advantage," they pointed out. "The consequences of failure on your part would be grave. Billions of federal healthcare dollars—and millions of lives—are at stake."
The lawmakers sent Oz a list of questions, requesting responses by December 23. They inquired about his views on traditional Medicare and revelations that "private companies overcharge taxpayers and unlawfully deny care." They also asked whether, as administrator, he would commit to "fully divesting of any and all financial holdings related to the insurance industry" and "recusing from any decisions that may impact insurers" in which he has a stake.
Sharing the letter on social media Wednesday, Accountable.US said that Warren "is right: this glaring conflict of interest endangers seniors and puts billions in corporate pockets."
"There's every reason to expect the Trump administration to block these proposed rules from moving forward," warned Public Citizen co-president Robert Weissman.
The Biden administration on Tuesday unveiled a new rule aimed at reining in privatized Medicare Advantage plans, which have drawn growing federal scrutiny for denying coverage claims en masse—sometimes using artificial intelligence—and overbilling the government to the tune of tens of billions of dollars per year.
But the proposal could soon be fed through the buzzsaw of the incoming Trump administration, which is likely to have an outspoken Medicare Advantage supporter, Mehmet Oz, at the helm of the Centers for Medicare and Medicaid Services (CMS).
Biden's CMS said in a fact sheet released Tuesday that the new rule would ensure MA companies make enrollees aware of their right to appeal coverage denials. CMS pointed to data showing that MA plans, which now cover more than half of the Medicare-eligible population, "overturn 80% of their decisions to deny claims when those claims are appealed."
"These data also show that a low percentage of denied claims are appealed, meaning many more could potentially be overturned by the plan if they were appealed," CMS added.
The rule would also look to constrain MA plans' deceptive marketing practices and "use of inappropriate prior authorization." Prior authorization is a byzantine process under which providers must demonstrate that a proposed treatment is medically necessary before the insurer will cover it.
"The big question, of course, is what will the Trump administration do with these rules? Will they side with patients needing treatment or care-denying big insurers?"
Robert Weissman, co-president of the consumer advocacy group Public Citizen, welcomed the new rule as a "common-sense" measure that would "limit" some of the damage inflicted by MA plans, which are notorious for denying patients necessary care.
"The big question, of course, is what will the Trump administration do with these rules? Will they side with patients needing treatment or care-denying big insurers?" Weissman continued. "Unfortunately, despite its populist pretensions, there's every reason to expect the Trump administration to block these proposed rules from moving forward. Dr. Mehmet Oz, Trump's nominee to run the Centers for Medicare and Medicaid Services, is a major proponent of expanding privatized Medicare, with nary a worry about privatized Medicare's rampant abuses and rip-offs of taxpayers."
Sen. Ron Wyden (D-Ore.), chair of the Senate Finance Committee, vowed Tuesday that he will "be watchdogging the incoming Trump administration to ensure there is no backsliding on these critical consumer protections and coverage improvements."
Oz, a long-time television personality known for hawking unproven treatments, has been characterized as a "shill" for MA, a program funded by taxpayers and run by for-profit insurance companies.
As recently as August, Oz boosted Medicare Advantage on his YouTube account, as New York magazine reported earlier this week:
In August, Dr. Mehmet Oz's official YouTube account posted a video titled "Get $0/Month Medicare Coverage: What You Need to Know," in which Oz lays a sales pitch on his viewers. "Which of these items can you get for zero dollars?" he says, pointing to images of a coffee cup, a pack of gum, and a newspaper, as if quizzing a toddler on the pictures in a children’s book. "Or how about a health insurance plan?" he says. If you've ever watched daytime television, you know how the next part goes: Oz reveals he was, indeed, talking about the health insurance plan, and the studio audience erupts into applause. He then brings out an insurance agent to paint a rosy portrait of Medicare Advantage before ending with a call to action, encouraging any seniors in the audience to call in to a special phone number or visit a website to learn more and enroll.
During his 2022 bid for a U.S. Senate seat, Oz campaigned on a proposal he called "Medicare Advantage for All"—while owning stock in UnitedHealth Group, the nation's largest MA insurer.
Oz's support for Medicare Advantage aligns with the Project 2025 agenda, which calls for making MA the default enrollment option for U.S. seniors—an existential threat to traditional Medicare. Such a sweeping change would hugely benefit UnitedHealth and other private insurance giants.
"Project 2025's plans for Medicare, seconded by Dr. Oz, will end Medicare as we know it, and leave seniors to the tender mercies of dishonest and debased private insurance plans," The American Prospect's Robert Kuttner warned Tuesday. "What's insidious is that none of these changes require legislation. The best we can hope for is that the sunlight of exposure of these schemes will act as a disinfectant."
