Short-term health insurance is having a moment.
With ACA marketplace premiums climbing and subsidies set to shift, search traffic for "cheap health insurance" keeps spiking, and brokers are pushing short-term plans as the obvious fix.
The pitch is simple: pay a fraction of what a marketplace plan costs, get covered tomorrow.
The catch is buried in what these policies actually do when you need them.
These plans are not required to cover the ten essential health benefits that ACA plans must include.
That means no guaranteed coverage for prescription drugs, maternity care, mental health treatment, or preventive visits.
Some policies cap how much they'll pay per day or per condition.
Others exclude entire categories of care outright, so a single diagnosis can leave you covering the bill yourself.
The pricing gap is real, and so are the trade-offs.
A short-term plan might run $100 to $200 a month for a healthy 40-year-old, while an unsubsidized ACA silver plan could cost two or three times that.
It's the cost of the protections you're giving up, repackaged as savings.
Here's the part that surprises people most.
Short-term plans can deny you coverage based on your medical history, and they can rescind a policy after the fact if they find an error on your application.
If you've had cancer, diabetes, or even a treated back injury, you may be rejected or charged more — or approved and then dropped when the claims get expensive.
Brokers earn commissions on these plans, and they often earn more per enrollee than they do on marketplace policies.
Some websites that rank high for insurance searches are lead-generation operations that sell your contact information to multiple agents.
The friendly quote you requested can turn into a week of phone calls.
If you're between jobs, waiting for Medicare to start, or need a bridge for a month or two, a short-term plan can beat going uninsured.
The math changes if you have ongoing prescriptions, a chronic condition, or any real chance of needing care beyond a routine checkup.
Before you buy, read the actual policy document, not the marketing page.
Look for the deductible, the out-of-pocket maximum, the list of excluded conditions, and whether prescriptions are covered at all.
Ask the agent, in writing, what happens if you get diagnosed with something serious next month.
These plans exist because they're allowed to segment risk, which is exactly what the ACA's rules were designed to stop.
Every healthy person who leaves the marketplace pool for a cheaper alternative can push premiums higher for everyone who stays, including people who can't qualify for anything else.
That's not a hypothetical — it's how insurance math has always worked.
None of this makes short-term coverage illegal or useless.
It makes it a tool with a specific job and sharp edges.
Treat it like a temporary patch, not a replacement, and you'll avoid the surprise that sends people to GoFundMe pages every year.
The honest takeaway: if a plan is dramatically cheaper, someone is absorbing less risk on your behalf, and that someone is you.
Read the exclusions before you sign, and don't let a low monthly number stand in for actual protection.
Final Thoughts
Cheap coverage that folds when you get sick isn't a bargain — it's a bill waiting to happen.
