Short-term health insurance is having a moment.
With ACA marketplace premiums climbing and open enrollment windows locked to specific dates, more Americans are typing "cheap health insurance" into search bars and landing on plans that promise coverage in 24 hours for a fraction of the price.
Here's what those plans actually are: stripped-down policies that can exclude pre-existing conditions, skip maternity and mental health care, and cap how much they'll pay in a year.
They were designed as a stopgap — coverage for a few months between jobs — not as a permanent substitute for real insurance.
The Trump administration expanded these plans in 2018, letting insurers offer terms up to 364 days and renew them for up to three years.
The Biden administration cut that back to four months, but the product never disappeared.
It just moved online, where ads target gig workers, freelancers, and anyone who just got a quote from Healthcare.gov and flinched.
A 40-year-old in Texas might see a short-term plan for $150 a month versus $450 on the marketplace.
That gap is real money for a household already stretched by rent and groceries.
But the gap exists because the plan isn't covering the same things — and the bills you don't see coming are exactly the ones that wreck a budget.
Many short-term plans won't pay for prescriptions, doctor visits related to a condition you had before enrolling, or anything the insurer decides falls outside "medically necessary." Some cap annual payouts at $250,000 or less.
One surprise diagnosis — cancer, a heart issue, a bad accident — can blow past that ceiling in weeks.
Unlike ACA plans, short-term insurers can ask about your health history and reject you outright.
If you develop a condition while covered, they can refuse to renew you when the term ends.
You're renting it, month to month, until you need it most.
None of this means the plans are illegal or useless.
If you're between jobs, waiting on employer coverage to kick in, or aging into Medicare, a short-term plan can beat going uninsured.
The mistake is treating it as a long-term solution and skipping the details that determine whether it actually pays.
Before you buy, read three things: the exclusions list, the annual maximum, and the renewal terms.
If a plan won't show you those clearly, that's your answer.
And check whether you qualify for subsidies on Healthcare.gov — roughly 4 in 5 marketplace enrollees do, and those subsidies can shrink the price gap more than people expect.
Our take: short-term coverage is a bridge, not a house.
Final Thoughts
Use it to cross a gap, not to live in — and never let a low monthly premium talk you out of reading what it won't pay for.
