Short-term health insurance is having a moment again, and not because anyone is excited about it.
With ACA marketplace premiums projected to climb sharply for 2026 and enhanced subsidies still tangled up in Congress, millions of Americans are quietly searching for something cheaper.
Enter the plans that promise coverage in days, no waiting for open enrollment, and monthly bills that look almost too good.
These policies were never designed to be real health insurance.
They're temporary bridges, typically lasting anywhere from 30 days to just under 12 months depending on your state.
They can deny you for pre-existing conditions, charge you more based on your health history, and refuse to pay for anything tied to a condition you had before the policy started.
The list of what they often skip is long: maternity care, mental health treatment, prescription drugs, preventive care, and in many cases, hospitalization limits that cap out fast.
One emergency room visit or a surprise surgery can blow past a plan's maximum benefit and leave you holding a five-figure bill.
A short-term plan might run $100 to $200 a month for a healthy 40-year-old, while a marketplace bronze plan with subsidies removed could cost two or three times that.
When rent, groceries, and car insurance are all climbing, that difference feels impossible to ignore.
If you get sick, you're not just paying the premium.
You're paying the deductible, the coinsurance, and whatever the plan refuses to cover entirely.
Consumer advocates regularly warn that these policies generate some of the most complaints of any insurance product sold in the US.
Sign up for a short-term plan, skip the marketplace during open enrollment, and you may be locked out of subsidized coverage until the next enrollment window, unless you qualify for a special enrollment period.
That means a temporary fix can snowball into a year of thin coverage.
If you're considering one, read the actual policy document, not the sales page.
Look specifically at the maximum benefit amount, the list of exclusions, and whether prescriptions and hospital stays are covered at all.
Ask what happens if you get diagnosed with something serious in month two.
A few situations where these plans can make sense: you're between jobs and healthy, you're waiting for employer coverage to kick in, or you're aging into Medicare soon.
Outside of those narrow windows, a marketplace plan, a healthcare sharing ministry, or even a high-deductible ACA plan often leaves you better protected.
The honest takeaway is that cheap health coverage is rarely cheap when you actually need it.
If a plan's price seems dramatically lower than everything else, the savings are coming from somewhere, and it's usually the care you'd want most.
Final Thoughts
Read the exclusions before you sign, because that's where the real cost hides.
