The Centers for Medicare and Medicaid Services (CMS) reported significant progress in combating healthcare fraud in fiscal year 2025, with Medicare savings from preventing fraud, waste, and abuse reaching $42 billion. This represents an increase of nearly 60% over the previous year and marks the highest level of savings recorded in the program’s history.
CMS attributed the gains to a strategic shift from traditional recovery methods, which focused on clawing back funds after payments had been made, to a prevention-first approach aimed at detecting and stopping fraudulent activity before payments are issued. According to officials, nearly 70% of the savings resulted from prepayment interventions, including revoking fraudulent providers' enrollment, intercepting improper claims at submission, and halting payments before they cleared.
The savings are significant in practical terms; $42 billion could cover approximately 3 million knee replacements, 7 million cataract surgeries, or 37.5 million routine colonoscopies. Alongside financial benefits, the effort demonstrated a high return on investment, with CMS reporting more than $22 saved for each dollar spent on program integrity.
A central element of CMS’s anti-fraud strategy has been recognizing the scale and complexity of healthcare fraud, which often involves sophisticated, organized criminal enterprises that operate across state lines using rapidly changing billing addresses and ownership structures. To address this, CMS adopted a comprehensive monitoring system that integrates enrollment data, billing histories, and utilization patterns across programs to detect coordinated fraud networks rather than isolated incidents.
In one notable example, CMS launched a national crackdown on the home health and hospice sector following evidence of systemic abuse. The agency imposed an enrollment moratorium and suspended 808 providers nationwide, including those in California who billed $1.4 billion in 2025. Investigations upheld 80% of these suspensions when challenged, underlining the data-driven nature of the enforcement.
Additionally, CMS has secured unprecedented cooperation from all 50 states to undertake a coordinated Medicaid provider revalidation—a nationwide reassessment of providers authorized to bill Medicaid services. Early reports indicate progress, with Minnesota noting that more than half of high-risk providers have not passed revalidation.
Collaboration with federal and state law enforcement has also enhanced CMS’s capability to prosecute multi-jurisdictional fraud schemes. In 2025, CMS referred 372 cases involving $3.7 billion in alleged fraudulent billing to federal authorities. These referrals include thorough, cross-referenced data compiled to support prosecutions, exemplified by recent charges brought by the FBI’s Los Angeles office and the Central District of California against individuals accused of stealing over $50 million from Medicare.
CMS leadership emphasized that while the recent results demonstrate the effectiveness of the revised approach, sustained efforts are necessary to maintain momentum. Continued investment in data infrastructure, enforcement capacity, and interagency collaboration will be critical, as will ongoing congressional support to preserve and enhance the analytical tools central to this success.
Dr. Mehmet Oz, CMS administrator, and Kim Brandt, deputy administrator and chief operating officer, characterized the achievements as the foundation of a transformative anti-fraud program that benefits both Medicare patients and taxpayers while underscoring the need for vigilance to prevent future losses.
