Dr. Oz announces a 50-state audit of Medicaid program oversight

NEW YORK (AP) — The Trump administration will require all 50 states to explain their plans to revalidate some of their Medicaid providers in a national escalation of anti-fraud efforts that have so far largely focused on specific states, Dr. Mehmet Oz said Tuesday.

The Centers for Medicare and Medicaid Administrator said during a Politico health care summit that his agency plans to ask states to “own” the problem of health care fraud this week with requests for states to share their strategies within 30 days.

“It's an example of what we'd like them to do to prove that they're serious about this,” Oz said onstage Tuesday. “And if you don't take it seriously, it indicates to us that we might have to take the audits that we're doing to the different states more aggressively,” he said, without elaborating.

Tuesday's announcement is part of a federal campaign to tackle waste, fraud and abuse in federal Medicaid and Medicare programs that so far has mostly targeted Democratic states — and at least once has erred in its accusations.

Earlier this month, The Associated Press reported that CMS made a significant error in figures it used to help justify a fraud probe in New York. The acknowledgment deepened doubts in the administration's methods and raised a common criticism that has been made about the second Trump administration — that it tends to attack first and confirm the facts later.

In addition to New York, CMS has approached at least four other states with investigations into potential health care fraud and halted some $243 million in Medicaid payments to one of them, Minnesota, over fraud concerns. It also is blocking for six months any new Medicare enrollments for suppliers of durable medical equipment, prosthetics, orthotics or certain other supplies around the country to address the potential for fraud. In addition, federal officials made several arrests earlier this month related to alleged hospice fraud schemes in the Los Angeles area.

Last month, Trump signed an executive order to create an anti-fraud task force across federal benefit programs led by Vice President JD Vance. It's unclear whether Tuesday's move is part of that effort, though Oz has been working closely with Vance on other investigations related to the task force. Asked for details on the new audit, a spokesperson for CMS said the agency was researching the AP's inquiry.

Oz justified Tuesday's move by saying federal health programs in some states have enrolled large numbers of providers who aren't providing real care to patients, but instead profiting from fraud. He said the requests for states to verify the legitimacy of Medicaid providers will be focused on “high risk areas,” but didn’t explain what those entail.

Minnesota Gov. Tim Walz, who the Trump administration and congressional Republicans have blamed for allowing fraud to happen in federally funded programs including Medicaid, welcomed Oz’s announcement.

Walz told reporters Tuesday that Minnesota hadn’t received the request yet, but the Democratic governor said his state is already moving ahead with the revalidation process and has made significant improvements. Minnesota sued CMS in February in an attempt to stop it from withholding Medicaid funds. That case is still ongoing, and the money has not yet been released, but CMS wrote to state officials last month that the agency had approved the state’s corrective action plan.

Asked during the Politico interview whether there was a risk that Trump administration initiatives could eliminate, slow down or harm essential health care programs, Oz said he expects the opposite. He said Medicaid and Medicare are the “crown jewels” of our nation.

“I believe this audit and others like it will save the programs we care most about,” he said.

ABUJA, Nigeria (AP) — The Nigerian army said Sunday it freed 360 people abducted by Boko Haram in southern Borno, in the northeastern part of the country.

The operation, according to the army’s statement, was conducted in the Mandara mountains which form a part of the militant group’s stronghold. It resulted in the release of several people, including children, who had been abducted across different communities in Borno.

Two infants “succumbed to exhaustion" due to the challenging mountainous terrain and the hardship they endured during their prolonged captivity, an army spokesperson, Haruna Sani, said.

“The remaining rescued abductees were successfully evacuated to safe locations for medical care and humanitarian support, marking a major operational success and a significant setback for the terrorist group,” Sani said.

Nigeria faces a complex security crisis, especially in the north where a more than decade-long insurgency and the activities of armed groups that carry out kidnappings for ransom and illegal mining have heightened the country’s security challenges.

Among the most prominent Islamic militant groups are Boko Haram and its breakaway faction, which is affiliated with the Islamic State group and known as Islamic State West Africa Province.

Last month, the West African country said its joint operation with the United States had killed 175 ISWAP fighters.

The insurgency in Nigeria’s northeast has killed thousands of people and displaced millions, according to the United Nations. Analysts say not enough is being done by the government to protect its citizens, despite repeated promises by President Bola Tinubu to curb the crisis.
