If you've shopped for health coverage between jobs or as a gig worker, you've seen them: short-term health insurance plans advertising premiums of $80 or $120 a month, a fraction of what an Affordable Care Act marketplace plan costs.
On paper, it looks like the obvious budget move.
In practice, these plans are built to make money by covering as little as legally possible — and the people selling them are counting on you not reading the fine print.
Short-term plans don't have to cover the ten essential health benefits that ACA plans must include.
That means no guaranteed coverage for prescription drugs, maternity care, mental health treatment, or pre-existing conditions.
Insurers can — and routinely do — investigate your medical history after you file a claim and cancel your policy if they find something you didn't disclose.
A 2020 study in the journal Health Affairs found that about half of short-term plan enrollees who filed claims had them denied.
The premiums are low because the risk pool is cherry-picked.
Healthy people who rarely see a doctor sign up, pay monthly, and never test the coverage.
The moment you actually get sick, the plan's limits kick in: annual caps on payouts, daily hospital limits, and networks so narrow that the nearest in-network ER might be an hour away.
One appendectomy can generate a bill in the tens of thousands of dollars that the plan covers only partially.
The brokers and call centers that sell these plans earn commissions that can run 20% to 30% of your first-year premium — far higher than what they get for enrolling you in a marketplace plan.
Some sales scripts blur the line between short-term plans and real insurance, using phrases like "ACA-compliant" or "Obamacare alternative" that aren't accurate.
Regulators have repeatedly fined marketers for misleading advertising.
The plans are also structurally profitable because the insurer keeps premiums from healthy buyers while paying out relatively little.
This matters more right now because the enhanced ACA subsidies that made marketplace coverage cheaper for millions of Americans are set to expire at the end of 2025 unless Congress acts.
If those subsidies lapse, premiums on the exchanges could spike for middle-income households, pushing more people to look at short-term plans as a stopgap.
That's exactly the scenario the short-term industry is positioned to exploit.
To be fair, these plans aren't illegal, and for a genuinely healthy person who needs a bridge of a few months and understands the gaps, they can function as catastrophic-only coverage.
But they are not a substitute for real insurance, and they were never designed to be.
If you're considering one, read the exclusions page before the price page, check whether pre-existing conditions are excluded, and compare the true annual cost against a subsidized marketplace plan — which you can price out on HealthCare.gov in about ten minutes.
The uncomfortable truth is that cheap health coverage in America usually means someone else is absorbing the risk you thought you were buying.
Short-term plans are a business model, not a safety net, and the gap between the pitch and the payout is where the profit lives.
Final Thoughts
If a premium looks too good to be true, it's because you haven't found the clause yet.
