Trump Administration Halts $1.6 Billion in Suspect Medicare Lab Payments, CMS Reports

The Centers for Medicare and Medicaid Services has suspended or recovered more than $1.6 billion in questionable Medicare laboratory payments since President Donald Trump returned to office, agency officials announced. The action included removing 157 lab providers from the Medicare program entirely, citing suspected fraudulent billing practices involving tests never performed or unnecessary procedures billed at inflated rates.

CMS Administrator Dr. Mehmet Oz emphasized the financial toll of such schemes on the Medicare system. “When laboratories bill Medicare for tests they never performed, it drains the Medicare Trust Fund and diverts resources away from beneficiaries who need them,” Oz stated in a statement accompanying the announcement.

In a notable Texas case, a consulting company owner enrolled 14 laboratories in Medicare and submitted billings exceeding $24 million despite none of the facilities appearing operational, according to CMS records. The agency has withheld $12 million in payments to the suspected fraudulent labs and recovered an additional $7 million, with eleven of the fourteen facilities now permanently removed and three remaining under active investigation.

The agency is deploying artificial intelligence technology to identify abnormal billing patterns indicative of fraud across the Medicare claims system. The automated tools flag suspicious submissions for human review before payment is issued, allowing CMS to hold, reject or deny potentially fraudulent claims at the outset.

Of the $1.6 billion total, more than $500 million in suspected fraudulent payments were stopped through 185 payment suspensions following CMS investigations into 600 laboratories nationwide. The agency also recovered $276 million in overpayments made to 442 suspect facilities and referred 85 cases to law enforcement, preventing an additional $127 million in potentially improper payments.

Two recent Texas laboratory cases illustrate CMS’s detection methods. One lab submitted suspicious claims beginning in late February, prompting CMS to deny $1.2 million in charges. When the provider altered its billing approach in April to circumvent agency safeguards, officials continued monitoring and blocked more than $150,000 in additional payments before expulsion from the program that month.

A second Texas lab began heavy billing in May after submitting minimal claims earlier in the year, resulting in $1.9 million in denied claims and $1.7 million in captured payments. That facility remains under review for potential removal.

CMS credited its broader fraud prevention efforts with saving $42 billion during fiscal year 2025. Early in 2026, the agency identified $1.8 billion in Medicare overpayments and recovered $378 million through post-payment audits, while freezing more than $371 million in payments involving 267 providers and suppliers since January 1.
