Medicaid and ACA Enrollment Drops 5 Million — But Work Requirements Are Not Yet the Driver
Medicaid and ACA enrollment has fallen by over 5 million, but the primary drivers are the expiration of enhanced ACA subsidies and broad cuts in the 2025 reconciliation law, not Medicaid work requirements, which have yet to take effect in most states. CBO estimates the work requirement provision will cause 5.3 million people to lose Medicaid and become uninsured by 2034, but that harm is still pending.
Recent news that Medicaid and ACA enrollment has dropped by more than 5 million is alarming, but we must be precise about what is causing it. NBC News reports the decline stems "in part from President Trump’s 'big, beautiful' bill and the expiration of the enhanced ACA subsidies," explicitly noting that "many of the changes to Medicaid have yet to take effect, with the most consequential provision — Medicaid work requirements — set to begin in most states in January." So the current drop is driven mainly by the expiry of enhanced premium tax credits (which CBO estimates will cause 4.2 million people to become uninsured over a decade) and other early cuts from the reconciliation law, not by work requirements that have barely started.
That said, the work requirement provision is a time bomb. The Congressional Budget Office estimates that once fully implemented, the Medicaid work requirement will cause 5.3 million people to lose Medicaid and become uninsured in 2034 alone (CBO supplemental cost estimate, October 2025; confirmed by the Center on Budget and Policy Priorities and Georgetown CCF). This will compound coverage losses from other provisions, such as state per capita caps and cuts to Marketplace subsidies. The harms will fall disproportionately on Black, Latino, and rural communities, who are more likely to be enrolled in Medicaid and less likely to be able to navigate onerous administrative paperwork. The current enrollment drop is a preview of deeper damage to come if work requirements are allowed to take full effect — but we must not confuse the two timelines.
The humanitarian alternative
Congress should immediately repeal the Medicaid work requirements and restore the enhanced ACA premium subsidies that lowered out-of-pocket costs. Instead of requiring sick and low-income people to prove their work status through burdensome bureaucracy, the policy should focus on automatic enrollment and continuous eligibility. States should be incentivized to use existing data from unemployment insurance and wage databases to verify work status passively, eliminating the need for millions to navigate complex paperwork systems that are proven to cause coverage loss even among eligible enrollees. The savings from reduced administrative churn would offset the cost of maintaining coverage.
Falsifiable predictions
What this entry claims will happen, and what data would prove it wrong. The Reckoner revisits these against current reality.
- Within 90 days, state-level data will show that at least 3 million of the 5 million lost enrollees were eligible for Medicaid or subsidies but lost coverage due to procedural barriers, not ineligibility.
