Medicine Demands Trust—Dr. Oz Has Spent His Career Undermining It

If given the reins of CMS, Dr. Mehmet Oz will not only fail to improve healthcare for our seniors but also use privately managed care to actively harm Americans. The Senate must reject his nomination.

Medicine is about trust. As a medical student, I’ve been taught that trust in medicine is built on honesty, evidence, and a commitment to patient well-being—principles that should guide physicians and leaders in healthcare. But how can we trust a man who built a career on misleading patients to oversee healthcare for 160 million Americans?

Dr. Mehmet Oz, a former TV doctor notorious for promoting unproven “miracle cures,” has been nominated by U.S. President Donald Trump to lead the Centers for Medicare and Medicaid Services (CMS)—an agency that millions of seniors, children, and low-income families depend on for care. Yet, he promotes predatory Medicare Advantage programs and unscientific remedies that harm citizens. His nomination cannot stand.

As I take care of my own patients, I am consistently trained to practice evidence-based medicine and uphold ethical standards that prioritize patient well-being. Dr. Oz, in contrast, has used his platform to spread misinformation, undermining the very trust that medicine depends on. Formerly a well-regarded cardiothoracic surgeon, Dr. Oz began his journey toward harm over healing on the “Dr. Oz Show,” a nationally televised program on which he promoted unproven treatments that interfered with patients' appropriate medical care.

As the head of CMS, he would have direct influence over policies that could drive billions in profits for private insurers, companies that he has already aligned himself with.

Pennsylvania doctors even launched “Real Doctors Against Oz” to protest his 2022 U.S. Senate run, arguing that he was a “major threat to public health.” He skirted ethical responsibilities when he supported evidence-lacking recommendations to use hydroxychloroquine for Covid-19 while owning stock in the pharmaceutical companies that supply the drug and has been criticized by Congress for inappropriate claims he made about green-coffee extract as a weight-loss medication.

Dr. Oz will have an even more deleterious impact on seniors’ health, having expressed a clear intent to expand Medicare Advantage, privately managed Medicare. Medicare Advantage (MA) is rapidly reshaping senior healthcare at the expense of patient well-being. In Maryland, the proportion of MA enrollees to total Medicare beneficiaries has more than quintupled (5% to 27%) in the last decade. Seniors in these plans, especially those with significant medical conditions, are more likely to drop these plans and return to traditional Medicare because of increased denials of medically necessary care and delays accessing care due to narrow networks and increased bureaucracy. Becoming locked into a system where administrative bloat and corporate profits result in up to $140 billion in overpayments annually to Medicare Advantage companies would not only drain the Medicare trust fund but also harm seniors as cancer patients in Medicare Advantage face worse outcomes.

Even more concerning, Dr. Oz currently has a personal financial stake in the expansion of Medicare Advantage. His disclosure forms reveal he owns between 280,000 and 600,000 shares in UnitedHealth Group, the largest Medicare Advantage insurer. He has committed to divesting from these holdings if confirmed. Even still, as the head of CMS, he would have direct influence over policies that could drive billions in profits for private insurers, companies that he has already aligned himself with. Dr. Oz’s profiteering from these investments represents his prioritization of financial self-interest over patient well-being—and makes him uniquely unqualified to oversee public health programs.

Right now, we are pivoting sharply toward doing more harm at a time when we desperately need to pivot toward providing better healthcare for everyone. Medicare for All is supported by 69% of registered voters and provides truly universal coverage while cutting administrative overhead, reining in healthcare costs, and saving Americans thousands by removing the private insurance middleman. More importantly, it would make America healthy again; with prevention and primary care finally prioritized, Americans can enjoy better healthcare outcomes and quality of life.

As a Philadelphia anesthesiologist said in The New York Times, “I can’t believe he took the same oath that I did when we graduated… that oath is about first doing no harm.” As I prepare to take this same oath, I am appalled that someone who has so blatantly violated its principles could be entrusted with the health of millions. If given the reins of CMS, Dr. Mehmet Oz will not only fail to improve healthcare for our seniors but also use privately managed care to actively harm Americans. The Senate must reject Dr. Oz’s nomination. His long track record of misleading the public, pushing corporate interests, and prioritizing profit over patient health makes him wholly unfit to lead CMS.

Warren Urges Medicare Nominee Oz to 'Divest From Financial Conflicts of Interest'

"By making these commitments, you would increase Americans' trust in your ability to serve the public interest during your time at CMS—rather than the special interests of companies in your network."

U.S. Sen. Elizabeth Warren on Wednesday called on Dr. Mehmet Oz, President Donald Trump's nominee to head the federal agency in charge of Medicare, to divest all financial ties to Big Pharma and healthcare companies in order to avoid conflicts of interest and gain the public's trust.

"Congratulations on your nomination to serve as administrator of the Centers for Medicare and Medicaid Services (CMS)," Warren (D-Mass.) wrote in a letter to the celebrity heart surgeon and erstwhile purveyor of phony weight loss cures. "If confirmed, you will be expected to steward CMS' $1.5 trillion budget in the best interest of the over 140 million Americans on Medicare and Medicaid. Entering this role with financial conflicts of interest would undermine your effectiveness and the effectiveness of the programs you are slated to administer."

"To avoid this, I request that you agree to: divest any remaining financial interests in health-related companies or patents that you will have the power to influence, recuse from matters involving your former employers and clients, and, for at least four years after you leave office, not lobby CMS or join the industries that depend on CMS' work," the senator said.

"Entering this role with financial conflicts of interest would undermine your effectiveness and the effectiveness of the programs you are slated to administer."

"By making these commitments, you would increase Americans' trust in your ability to serve the public interest during your time at CMS—rather than the special interests of companies in your network," she added.

"You have deep ties to companies that could profit from your decisions at CMS," Warren noted. "You currently serve as a managing member or adviser of multiple healthcare and pharmaceutical firms with a financial stake in CMS policy, including how the agency sets payment rates and coverage determinations for Medicare and Medicaid."

Warren continued:
You also use your public platforms—including your website, TV show, TikTok, and Instagram pages—to promote drugs, such as Ozempic, produced by pharmaceutical companies that are currently seeking expanded CMS coverage approval and that are subject to government drug negotiations—which you would be responsible for conducting. You have been paid to push your show's viewers to enroll in the private alternative to Medicare, Medicare Advantage—a program run by private health insurers that overcharged CMS by at least $83 billion in 2024 alone.

Doctors have critiqued you for allegedly "promoting quack treatments and cures in the interest of personal financial gain." Furthermore, much of your financial portfolio (worth at least $98 million) is invested in healthcare and pharmaceutical companies whose value is tied to CMS' regulatory work.

Last December, the watchdog Accountable.US revealed that Oz had invested as much as $56 million in three companies with direct CMS interests. In 2022, Oz's single biggest healthcare holding was up to $26 million in Sharecare, a digital health company Oz co-founded, and which became the exclusive in-home supplemental care program for 1.5 million Medicare Advantage customers.

On Tuesday, the consumer advocacy group Public Citizen published a research brief examining the hundreds of millions of dollars spent on political lobbying by Medicare Advantage companies ahead of Oz's confirmation hearing, which is scheduled for Friday morning.

Warren and other Democratic lawmakers previously pressed Oz on his advocacy for Medicare privatization, including a 2020 call for enrolling all U.S. seniors in Medicare Advantage plans.

Last month, Oz pledged to divestfrom insurance companies and drugmakers and step down from his advisory positions if his nomination is confirmed.

"I appreciate that you have agreed to divest much of your portfolio and resign from your advisory posts," Warren wrote. "Still, given your close ties to the industry that you would regulate, if you are confirmed, the public would have reason to question your impartiality and commitment to serving the public's interest."
