Shoppers hunting for cheaper coverage during open enrollment keep landing on the same search result: short-term health insurance.
These plans typically cost far less per month than an ACA marketplace policy, and they are now marketed heavily to gig workers, early retirees, and anyone facing a steep premium increase.
Short-term plans can deny applicants with pre-existing conditions, cap annual payouts, and skip benefits like maternity care, mental health treatment, and prescription drugs.
A plan that looks like a bargain at $120 a month may leave you writing checks for everything that matters.
The rules have shifted depending on who sits in the White House.
Federal guidance expanded these plans in 2018, allowing terms of up to 364 days and renewals lasting three years.
The Biden administration tightened that back to four months in 2024.
State law matters just as much, since some states ban the plans outright while others allow them with limits.
Here is where the money math gets interesting.
Say a marketplace plan runs $550 a month after subsidies and a short-term plan runs $150.
That is $4,800 in annual savings, which sounds great until a single emergency room visit or a surprise diagnosis blows past the plan's coverage cap.
Many short-term policies also exclude coverage for accidents related to certain activities and pay a fixed daily amount for hospital stays rather than the full bill.
Two consumer protections are worth knowing before you buy.
First, these plans are not required to spend a set percentage of premiums on medical care, so more of your money can go to overhead.
Second, if you have a short-term plan and later apply for an ACA policy, you may be asked detailed health questions, though marketplace plans must accept you regardless of health status during open enrollment.
Someone between jobs for two or three months, a healthy 26-year-old aging off a parent's plan, or a worker waiting for employer coverage to start.
Even then, compare it against a marketplace plan with a subsidy, because many households qualify for premiums under $50 a month once tax credits are applied.
Checking Healthcare.gov first takes ten minutes and can change the entire calculation.
If you decide a short-term plan fits a genuine gap, read the exclusions page, not the brochure.
Look for the annual maximum, the deductible, the prescription list, and whether renewals require new health questions.
Ask what happens if you get sick mid-term, because some insurers cancel at renewal rather than cover ongoing treatment.
The plans are legal, widely sold, and occasionally the right tool for a narrow window.
They are simply not a substitute for real coverage, no matter how the ad words are arranged.
My take: short-term policies are a bridge, not a home.
Final Thoughts
If you can qualify for a subsidized marketplace plan, run the numbers before chasing the lowest sticker price, because the cheapest premium is rarely the cheapest outcome.
