WASHINGTON — The U.S. Senate on Thursday confirmed former television personality and onetime Pennsylvania political candidate Mehmet Oz as director of the Centers for Medicare & Medicaid Services.
The 53-45 party-line vote places Oz at the helm of the federal agency responsible for administering health care programs relied on by 1 in 4 Americans, including children, seniors and lower-income people.
His confirmation comes as Republicans in Congress look to Medicaid, a state-federal partnership that covers medical expenses for some low-income and older Americans, as a source for hundreds of billions in spending cuts to help pay for extending the 2017 GOP tax law.
Oz testified during his confirmation hearing in mid-March that there are several “painful truths” confronting federal programs within CMS.
“Health care expenditures are growing 2 to 3% faster than our economy; not sustainable. The Medicare trust fund will be insolvent within a decade, that’s the 2.9% taken out of your paycheck,” Oz said. “Medicaid is the number one expense item in most states, consuming 30% of those state budgets, and that’s crowding out essential services like schools and public safety that many of you spent your careers trying to develop. Our health care cost per person in this country is twice that of other developed nations.”
Oz said that chronic disease, which he argued is “linked to poor lifestyle choices,” drives much of the federal spending on health care. He singled out obesity as a central issue.
Oz testified he intended to “empower beneficiaries with better tools and more transparency,” “incentivize health care providers to optimize care with real-time information” in part by using artificial intelligence to “liberate doctors and nurses from paperwork,” and modernize efforts that track waste, fraud and abuse.
‘Ludicrous wellness grifting’
Finance Committee ranking member Ron Wyden, D-Ore., said during the hearing that Oz’s comments during a failed Senate campaign about privatizing Medicare were unacceptable.
Wyden also criticized Oz for promoting products on this daytime television show that had no scientific research supporting their claims of improving people’s health or preventing disease.
“Dr. Oz has used his program to promote some of the most ludicrous wellness grifting that I’ve heard about to date,” Wyden said.
Idaho Republican Sen. Mike Crapo, chairman of the committee, said during a floor speech Thursday that Oz was well qualified to run CMS.
“At his hearing, Dr. Oz spoke strongly about his desire to modernize the CMS and encourage a healthy lifestyle for all Americans,” Crapo said. “His vision for treating the underlying causes of chronic disease and equipping providers with innovative technologies to serve patients will also be a much- needed sea change at CMS.”
CMS scope
The agency manages several federal health programs, including Medicare, Medicaid, the Children’s Health Insurance Program and the health insurance marketplaces established by the Affordable Care Act.
The agency spent more than $1.5 trillion during the last full fiscal year, about 22% of all federal spending.
The more than 6,000 people who work at CMS as well as contractors “process over one billion Medicare claims annually, monitor quality of care, provide the states with matching funds for Medicaid benefits, and develop policies and procedures designed to give the best possible service to beneficiaries,” according to the latest financial report.
CMS is one of many agencies housed in the Department of Health and Human Services that is subject to restructuring plans from Secretary Robert F. Kennedy Jr.
Oz background
Oz received his undergraduate degree from Harvard University before earning a joint M.D. and MBA from the University of Pennsylvania School of Medicine and Wharton Business School.
He starred in the daytime show “Dr. Oz,” which ran from 2009 until 2022.
He won the Republican primary in the 2022 Pennsylvania U.S. Senate race but was defeated during the general election by Democratic Sen. John Fetterman.
When President Donald Trump announced in November he intended to nominate Oz to lead CMS, he wrote that Oz would “cut waste and fraud within our Country’s most expensive Government Agency, which is a third of our Nation’s Healthcare spend, and a quarter of our entire National Budget.”
