The pitch lands in your inbox right after you lose a job or watch your COBRA quote arrive: health coverage for a fraction of what you were paying.
Short-term health insurance can look like a life raft, with premiums that sometimes run a third of an Affordable Care Act plan.
It is a different product wearing a familiar name.
These plans were originally designed to bridge small gaps — a few months between jobs, say.
Federal rules stretched the maximum duration to just under 12 months in many states, and some states allow renewals that keep people covered far longer.
The Trump administration is now weighing another expansion.
Whatever happens in Washington, the consumer math stays the same: you get a lower bill because the plan promises to pay for less.
What gets left out is the part that matters most.
Short-term plans can deny coverage entirely if you have a pre-existing condition, and they can refuse to pay for anything they decide is related to one.
So are prescription drugs, mental health treatment, and preventive care.
Even when a policy lists a benefit, the fine print often caps how much it will pay per day or per year — limits that ACA plans are not allowed to impose.
The people who sell these plans benefit from a simple asymmetry.
You do not see the claims department until you are already in a hospital bed.
Insurers in this market make money by collecting premiums and paying out as little as possible, which is not a scandal — it is the business model.
The friendly broker who calls it "major medical" is usually paid a commission, and that commission comes out of the same pool of money that would otherwise cover your care.
If you are healthy, between jobs, and need something to cover a freak accident for two or three months while you wait for ACA coverage to start, a short-term plan can beat going bare.
But the timing matters more than the price.
Hospital bills are the reason people buy insurance at all, and a surprise five-figure bill will erase years of premium savings in one afternoon.
Check whether you qualify for a subsidized ACA plan — many people who assume they earn too much are surprised by the numbers, especially after a job loss.
Read the exclusions page, not the marketing page.
And ask the seller, in writing, what happens if you get diagnosed with something expensive next month.
If the answer is vague, you have your answer. **The bottom line:** Cheap coverage is only cheap until you need it.
Short-term plans are a gamble that you will stay healthy during the exact window when you have the least protection, and the house usually wins.
Final Thoughts
If you can qualify for a subsidized ACA plan, that is almost always the better bet.
