Irregularities in ACA Enrollments: Concerns and Solutions

A recent analysis by the Paragon Health Institute reveals significant irregularities in Affordable Care Act (ACA) enrollments in Mississippi during the 2026 enrollment period. The report highlights potential issues of fraud and errors within ACA exchanges, emphasizing vulnerabilities particularly in the federal HealthCare.gov platform. This raises concerns over regulatory compliance and the integrity of enrollment processes.

Liam Sigaud, an Adjunct Scholar at Paragon and Research Associate at the Knee Regulatory Research Center, defines "improper enrollment" as instances where individuals mistakenly receive subsidies. While not all cases are fraudulent, Sigaud points to structural weaknesses, including inadequate identity verification and accessible broker systems, possibly leading to unauthorized enrollments in ACA programs.

The findings indicate that out of 313,392 sign-ups in Mississippi, about 79% reported income levels between 100% and 150% of the federal poverty line. This statistic suggests a misalignment with the state's actual income distribution, hinting at improper subsidy claims. The report identifies brokers who might enroll individuals without consent, motivated by financial incentives tied to commissions from these enrollments.

A related case in Florida highlights such vulnerabilities, where a Department of Justice investigation implicated an insurance brokerage in fraudulent enrollment schemes. These actions yielded unwarranted subsidies and significant financial penalties, underscoring system abuse potential, where enrollees were often unaware of their inappropriate sign-ups.

The report further notes that Mississippi had the highest percentage of ACA enrollees with unspecified race or ethnicity. This anomaly suggests possible non-consensual enrollments facilitated by intermediaries. While there was a decrease in estimated improper enrollments from 2025 to 2026, systemic challenges in enrollment integrity persist.

Efforts to establish a state-run exchange in Mississippi have encountered legislative hurdles. Proponents argue that a state-based marketplace could enhance regulatory compliance and enrollment integrity through improved oversight. Sigaud recommends stricter federal regulations and increased local oversight as interim solutions to enhance insurance practices in Mississippi.

The broader report implications underscore significant taxpayer expenses, with projected improper subsidy disbursals potentially reaching $25 billion nationwide in 2026. In Mississippi, improper enrollments could cost over $600 million, necessitating ongoing scrutiny and reforms in ACA exchange management to mitigate financial risk and ensure proper resource allocation.
