The Math of the Uninsured

A subsidy expired on a schedule nobody hid. The bill it left behind is already showing up in the survey data, one open-enrollment season later.

And Then You're Dead · August 2026 · 3 min read

Enhanced Affordable Care Act premium subsidies expired at the end of 2025 — a known date, not a surprise. What happens after a known deadline like that isn't usually visible for months. This time, it showed up almost immediately.

What the Subsidy Was Doing

The enhanced subsidies, first passed in 2021 and extended through 2025, capped what marketplace enrollees paid as a share of income. Once they lapsed, premiums didn't rise gradually — they reset.

The Urban Institute's pre-expiration modeling projected 4.8 million people would lose coverage entirely — a 21% jump in the national uninsured rate — with millions more staying insured but paying sharply more for it.

What Actually Happened

Projections are one thing. A few months into 2026, there's real survey data measuring what people actually did when the bill came due.

9% of people enrolled in an ACA marketplace plan in 2025 are already uninsured in 2026, according to a KFF survey fielded in February and March.

Roughly one in eleven people who had coverage a year earlier simply don't anymore. Among those who did re-enroll, 17% said they weren't confident they could afford their premium for the full year — meaning the 9% figure is a floor, not a final number, if their income doesn't stretch to match.

What Coverage Was Actually Buying

The number on the premium bill is the trade for a much larger number sitting on the other side of it — what happens if something goes wrong and there's no coverage at all.

That's an average — a serious case can run into five figures before a single follow-up appointment. Registration and facility fees alone typically run over $1,000 combined before any actual treatment happens. Self-pay discounts and hospital financial-assistance programs exist and can meaningfully cut the number, but only for people who know to ask, which isn't the same as it being built into the price.

And Then You're Dead

A subsidy expiring on schedule isn't a scandal — it's a policy choice with a known effective date, debated in public, decided by people whose own coverage was never at stake. The 9% already measured this year is what that choice looks like in practice, running months ahead of the full projection. The gap between a $1,904 premium and a $2,863 emergency room bill isn't really a gap at all. It's the same math, paid on two different schedules, by two different groups of people who used to be one group with a subsidy.

That's it. That's the whole thing.
