$47 billion in Obamacare fraud discovered

Republican lawmakers and investigative reports highlighted nearly $47 billion in improper payments and potential fraud within the Affordable Care Act (ACA) marketplace. This figure stems from a series of reports, including a new investigation from the nonpartisan Government Accountability Office (GAO), which exposed systemic vulnerabilities in how health insurance subsidies are distributed.

According to the findings, the federal marketplace frequently approved insurance applications and issued taxpayer-funded subsidies even when applicants provided fake Social Security numbers, falsified citizenship documents, or no documentation at all. The GAO investigation utilized "secret shopper" tactics, creating 20 fictitious identities to test the system's integrity during the 2024 and 2025 plan years.

In a striking result, 100% of fake applicants were approved for subsidized coverage in late 2024, and 18 of the 20 fictitious enrollees continued to receive taxpayer-funded subsidies as of September 2025. Auditors also discovered massive irregularities in Social Security number (SSN) usage, including one instance where a single SSN was used to enroll in 125 different policies in 2023, totaling approximately 71 years' worth of insurance credits.

Additionally, more than 58,000 SSNs receiving subsidies were found to match federal death records, resulting in millions of dollars in payments for deceased individuals. Legislators have noted that the expansion of enhanced COVID-era tax credits, which increased the value of subsidies, likely created a stronger financial incentive for unscrupulous brokers and "bad actors" to exploit the system.

While some analysts from the Paragon Health Institute projected that improper enrollment could reach 6.4 million people at a cost of $27 billion for 2025 alone, the broader $47 billion figure reflects a cumulative estimate of improper payments cited by GOP members in congressional hearings. These findings have fueled intense debate in Washington regarding whether to extend enhanced ACA subsidies or implement stricter verification requirements to protect taxpayer funds
