The pitch lands in your inbox or your feed right after a job change, a layoff, or a scary quote from Healthcare.gov: coverage starting tomorrow, premiums under $200 a month, no network hassles.
Consumer advocates and state regulators say it is often something closer to a trap with a low introductory price.
Short-term health insurance is not comprehensive major medical coverage, even though the marketing frequently blurs that line.
These plans were originally designed as temporary bridges of a few months.
Federal rules expanded them to offer up to 364 days of coverage, renewable for up to three years in many states, which is long enough that people mistake them for real insurance.
Here is the catch that matters most: these plans can deny you coverage entirely if you have a pre-existing condition, and they can refuse to pay for care related to anything they decide was pre-existing.
That determination does not require a formal diagnosis.
A past prescription, a mention of chest pain in an old chart, or a prior test can be enough to trigger a denial.
Many plans skip maternity care, mental health treatment, prescription drugs, and preventive services.
Some cap what they will pay per day or per condition.
A broken leg or an overnight hospital stay can blow past those limits fast, leaving you with a bill that dwarfs whatever you saved on premiums.
The sales machine behind these products is worth following.
Brokers and lead-generation websites can earn hefty commissions, which gives them a strong incentive to steer callers toward short-term plans rather than ACA marketplace coverage.
Some shoppers report being told the plan was "Obamacare-compliant" when it was not.
Complaints about misleading marketing have piled up in state insurance departments for years.
A few numbers put the tradeoff in perspective.
Subsidized ACA marketplace plans often cost less than short-term coverage once you factor in tax credits, especially for households earning under roughly four times the federal poverty level.
Those marketplace plans must cover pre-existing conditions and a set of essential benefits.
The catch is that you generally need to enroll during open enrollment or qualify for a special enrollment period, and that window is tighter than most people expect.
If you are staring down a coverage gap, the practical moves are boring but effective.
Check Healthcare.gov or your state exchange first, even if you assume you earn too much.
Ask your state insurance department whether short-term plans are even sold where you live, since several states have restricted or banned them.
If you do buy one, read the exclusions page before the price page, and get any verbal promise in writing.
Short-term plans are not automatically a scam, and for a healthy person bridging a genuine two-month gap, they can function as intended.
But they are a gamble dressed as a bargain, and the house writes the rules.

Before you hand over a card, ask one blunt question: what happens if I actually get sick?
