If you're between jobs or waiting for coverage to kick in, a short-term health insurance plan can look like a lifesaver.
Premiums of $100 to $200 a month beat a $600 ACA marketplace plan, and the sign-up takes minutes.
But consumer advocates and state regulators keep warning that what you're buying often isn't what you think it is.
These plans, sometimes sold as "temporary" or "gap" coverage, aren't required to follow the Affordable Care Act's rules.
That means they can reject you for pre-existing conditions, charge more based on your health history, skip maternity care, and leave out prescription drugs entirely.
They also can cap how much they'll pay out in a year or over your lifetime — a limit the ACA banned for real insurance.
The biggest trap is the fine print on what counts as a pre-existing condition.
Insurers in this market can dig through your medical records and deny claims for anything they decide you "should have known about." A 2019 study in the journal Health Affairs found that among people who filed claims, about half had them denied or billed for care they assumed was covered.
The pitch usually comes through a phone call or a slick website that mimics Healthcare.gov without ever saying it isn't the official marketplace.
Some lead-generation sites sell your information to brokers who then push these plans hard.
The commission on a short-term policy can run higher than on an ACA plan, which tells you who benefits from the sale.
If you're healthy, need a bridge for two or three months, and understand you're buying catastrophic coverage only, the math can work.
The mistake is treating one like a full insurance plan and then getting hit with a hospital bill that runs into the tens of thousands.
A handful of states — including California, New York, and Massachusetts — have effectively banned or heavily restricted these plans.
That patchwork means the rules depend entirely on where you live, so check your state's insurance department before you buy anything over the phone.
The closing opinion: Short-term plans aren't automatically a scam, but they're built to look cheaper than they are.
If you're healthy and truly between coverages, they can bridge a gap.
Final Thoughts
If you have any ongoing condition, take the marketplace route even at a higher sticker price — because the bill you avoid is the one that actually matters.
