Short-term health insurance has a reputation as the bargain bin of coverage.
You can find plans online in minutes, pay a fraction of what an Affordable Care Act plan costs, and get a card that looks like real insurance.
The catch is buried in the fine print, and it's a big one.
These policies are technically "short-term, limited-duration" plans.
They were designed as a temporary bridge for people between jobs or waiting for other coverage to kick in.
Federal rules now let insurers sell them for up to three years in many states, which makes them feel less like a stopgap and more like a permanent fix.
A 40-year-old might pay $150 a month for a short-term plan versus $450 or more for an ACA marketplace plan without subsidies.
That difference is why roughly a million Americans have tried them at some point, according to industry estimates.
What you give up is the part that matters.
Short-term plans don't have to cover pre-existing conditions.
They can reject you for a past back injury, high blood pressure, or a prescription you filled last year.
They can also cap how much they'll pay out per year, and they often skip categories that regular insurance must cover, including maternity care, mental health treatment, and prescription drugs.
If you get sick while on a short-term plan, the insurer can simply decline to renew you when the term ends.
You're left shopping for coverage with a new diagnosis on your record, and the ACA's protections won't apply because you weren't in an ACA plan.
The hospital bill math is where people get hurt.
A single emergency room visit for a broken leg can run $10,000 to $30,000 before insurance.
If your short-term plan has a $10,000 annual cap on payouts, you're on the hook for everything above it.
California, New York, and a handful of others restrict or ban these plans outright.
In most of the country, they're legal and heavily advertised, often with websites that mimic the official healthcare.gov marketplace.
If you're considering one, ask three questions before you type in a credit card number.
Is there an annual or lifetime payout cap?
Can the company drop me at renewal if I get sick?
If you don't like the answers, you've just saved yourself a very expensive lesson.
A better first move is checking your ACA subsidy on healthcare.gov.
Many households earning under about $60,000 qualify for tax credits that bring a real plan close to short-term prices.
Losing a job, getting married, or having a baby also opens a special enrollment window, so you don't have to wait until November. **The bottom line:** Short-term plans can fill a genuine gap for a few months if you're healthy and know exactly what you're buying.
Treating one as a long-term substitute for real coverage is a gamble that most American families can't afford to lose.
