Shopping for health coverage outside of open enrollment is a special kind of sticker shock.
A marketplace plan can run $400 to $700 a month for a family, while a short-term policy advertises $89.
The gap is real, and so is the reason for it.
Short-term health insurance was originally designed to bridge small gaps — a few months between jobs or before Medicare kicks in.
Federal rules loosened in 2018 let insurers sell policies lasting just under 12 months, renewable for up to three years in many states.
That turned a stopgap into a product marketed as a full substitute.
What you actually get for the lower premium is thinner coverage.
These plans typically exclude maternity care, mental health, prescription drugs, and pre-existing conditions.
Insurers can also rescind a policy or deny a renewal if you get sick — a practice the Affordable Care Act banned on ACA-compliant plans.
A policy might cap payouts at $250,000 or $1 million, which sounds generous until a single hospital stay runs past it.
And because these plans aren't required to cover the ACA's ten essential benefits, a $89 premium can quietly become a five-figure bill.
The ACA's individual mandate penalty is gone at the federal level, but a handful of states — including California, Massachusetts, New Jersey, Rhode Island, and DC — still tax the uninsured.
Buying a short-term plan may not satisfy those state requirements, so you could owe a penalty while also holding a policy you thought protected you.
Brokers earn commissions on these plans, and some lead-generation sites route shoppers toward them regardless of fit.
Insurers collect premiums from people who mostly stay healthy.
The people who lose are the ones who get hurt or diagnosed mid-policy.
That doesn't make short-term coverage useless.
If you're between jobs for 60 days, healthy, and need protection against a freak accident, it can beat going bare.
The math changes fast if you have any chronic condition, take regular medication, or might become pregnant.
Before buying, ask three questions: Does it cover prescriptions?
Can the insurer drop me at renewal if I file a claim?
Check healthcare.gov first — you may qualify for subsidies that shrink a marketplace premium below the short-term price.
If you're losing job coverage, compare COBRA costs against both options.
And read the exclusions page before the benefits page, because that's where the real story lives.
None of this is a knock on anyone trying to save money.
It's a warning that the cheapest premium is not the cheapest outcome.
A plan that costs $89 a month and covers almost nothing is a bet that you won't need it.
Our take: short-term health insurance is a legitimate tool for a narrow window, not a lifestyle.
Treat it like a spare tire — useful in an emergency, disastrous as your only set of wheels.
Final Thoughts
If a salesperson won't put the exclusions in writing, that silence is your answer.
