Short-term health insurance has a way of showing up exactly when you're most desperate.
You just lost a job, missed the ACA enrollment window, or got quoted $700 a month for a marketplace plan, and suddenly a $120 policy appears in your search results.
These plans are technically "short-term, limited-duration" coverage, and they were designed as a stopgap—a few months between jobs or before Medicare kicks in.
But federal rules loosened in 2018 let insurers stretch them out, and in many states you can now stay on one for up to three years.
Short-term plans can deny you for pre-existing conditions, which means the back pain you mentioned to your doctor last spring can get your application rejected outright.
They can cap how much they'll pay out per year—sometimes as low as $250,000, sometimes just $2,000 for prescriptions.
They frequently skip maternity care, mental health treatment, and prescription drugs entirely.
And they can rescind your policy if you made an honest mistake on your paperwork.
The price is what happens when you actually get sick.
One broken leg can run $30,000 before surgery.
A single hospital stay for something like pancreatitis can clear six figures.
If your plan caps out at $100,000 annually, you're holding the rest.
If it excludes the hospital you were taken to because it's out of network, you're holding all of it.
Consumer advocates have documented cases where people paid premiums for a year and still faced five-figure bills for care they assumed was covered.
They attract healthier people who don't expect to use them, and they pay out far less than comprehensive coverage.
Insurers make money when you stay well and drop you when you don't.
That math only works in your favor for as long as nothing goes wrong.
So what should you do if you're staring down a gap in coverage?
First, check Healthcare.gov even outside open enrollment—losing a job, moving, or having a baby triggers a special enrollment period that gives you 60 days to sign up.
Subsidies under the ACA often bring marketplace premiums down more than people expect, especially for families.
If you're between jobs, COBRA is expensive but it keeps your same doctors and networks.
If you're young and healthy, a catastrophic plan on the marketplace still covers the big stuff and can't reject you for pre-existing conditions.
If you do buy short-term coverage, read the exclusions page before the benefits page.
Know your annual cap, your deductible, your drug limits, and whether the plan covers anything before you hit that deductible.
Ask what happens if you're diagnosed with something chronic.
None of this means short-term plans are illegal or universally terrible.
If you're healthy, between coverage for 60 days, and just need protection against a catastrophic accident, one might hold you over.
But they are not a substitute for real insurance, and treating them like one is how people end up in medical debt they'll spend a decade digging out of.
The cheapest plan is rarely the cheapest outcome.

When it comes to your health, the fine print is the product—so read it like your savings depend on it, because they probably do.
