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

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.
