Remember back nearly two decades when the Affordable Care Act, also known as Obamacare, was meant to expand coverage and lower costs? Guess what it ended up doing instead? Far from delivering on its promises, premiums and deductibles remained high, insurer competition was weakened, and Congress continues to spend money.
As if those shortcomings weren't enough, a new study from the Paragon Health Institute suggests Obamacare may suffer from another serious problem: large-scale enrollment fraud and improper subsidy payments.
The Paragon Institute estimates that approximately 6.2 million people enrolled in Obamacare may be improperly receiving subsidized insurance, which accounts for can account for as much as one-quarter of total exchange enrollment. In fiscal terms, the report argues this could translate into as much as $20–25 billion in annual improper federal subsidy spending, depending on assumptions about eligibility verification and income reporting accuracy.
These issues are not coincidental; they are structural. First, eligibility for subsidies is heavily dependent on self-reported income, which is often based on projections as opposed to verified real-time earnings. This creates natural friction between reported income at the time of enrollment and actual income over the course of the year, especially for workers with variable earnings, gig income, or fluctuating hours.
Second, the system relies on delayed verification and post-enrollment reconciliation instead of strict upfront screening. This means discrepancies may not be corrected until after coverage has already been granted and subsidies disbursed.
Third, the growth of third-party brokers and automated enrollment platforms has increased the number of intermediaries involved in sign-ups. While many operate legitimately, the report argues that commission-based compensation tied to enrollment volume can weaken incentives for careful eligibility verification.
Finally, automatic re-enrollment mechanisms can allow previously enrolled individuals to remain in coverage even if their eligibility status has changed and was never fully rechecked.
This gets into a debate about how estimates of improper ACA enrollment vary widely depending on how “error” is defined and how aggressively small discrepancies are extrapolated across the full exchange population. Federal auditors like the Centers for Medicare & Medicaid Services and the Government Accountability Office generally focus on confirmed, verifiable errors, which tend to produce lower, single-digit to low-teens estimates.
Higher-end estimates, on the other hand, attempt to capture what those same processes are likely to miss when eligibility is based on self-reporting, delayed verification, and automatic renewal. Put simply, the lower estimates only measure what the system catches and acts as a low-bound estimate. The higher estimate is more plausible because it attempts to measure the full scale of eligibility drift.
Enrollment is frequently cited as evidence of the Obamacare’s success, but it is an incomplete metric. It captures participation in the system, not the accuracy or stability of that participation. In a framework built on self-reported eligibility, delayed verification, and automatic renewal, enrollment can rise even as underlying errors persist. The Paragon Institute’s findings highlight how large those gaps may be at scale.
The latest evidence on enrollment and subsidy error does not stand alone. It reinforces a longer pattern of structural problems that have followed the ACA since its inception, much like I pointed out in my 2017 piece listing 15 reasons we should all dislike Obamacare. Whether it is fraud rates, higher premiums, or fewer options, this latest Paragon Health report is a sobering reminder of why Obamacare should never have existed in the first place and how the American people are still paying for this boondoggle.
