Financial institutions flagged approximately $17.5 billion in suspicious activity related to potential health care fraud during a one-year period starting in 2025, according to a financial trend analysis released by the Financial Crimes Enforcement Network. The analysis examined 5,702 Bank Secrecy Act reports tied to potential health care fraud, providing a broad view of how suspicious activity is being identified and reported across the financial system.
Depositary institutions filed nearly 87% of the reports, which accounted for roughly the same percentage of suspicious activity amounts. The two largest institutions filed more than a quarter of reports. FinCEN found that perpetrators of suspected health care fraud often target more than one program or insurance provider, receiving funds from a combination of federal and state programs as well as private insurance companies. Home health care businesses were the most frequently identified health care providers in the reports. The overwhelming majority of subjects identified in reports were based in the U.S., with only 1.5% having a foreign address.
The concentration of filings among depositary institutions, and especially the two largest institutions, suggests that banks remain the primary detection point for suspicious health care-related transactions. The finding that suspected fraudsters often draw from multiple payers also indicates that cross-program coordination may be relevant for investigators, though the analysis does not establish whether the flagged activity resulted in enforcement actions or confirmed fraud.
What remains unknown is the outcome of the suspicious activity reports, including how many led to investigations, prosecutions, or recoveries. The analysis also does not specify the exact one-year period beyond starting in 2025, nor does it break down the $17.5 billion by payer type or fraud scheme. Because the available source is a single summary, the figures should be treated as reported activity rather than verified fraud losses.
