The pitch lands in your inbox or your feed with a number that stops you: coverage for $85 a month.
For anyone staring down a $600 COBRA bill or a marketplace quote that jumped again this year, that number is hard to scroll past.
Short-term health insurance is having a moment, and it is pulling in people who never imagined buying it.
Here is the catch that the ads leave out.
These plans are not required to cover the ten essential health benefits that Affordable Care Act plans must include.
That list covers prescription drugs, mental health care, maternity care, and treatment for pre-existing conditions.
A short-term plan can skip all of it, and many do.
The biggest trap is the pre-existing condition rule.
Under ACA rules, insurers must cover you regardless of your health history.
Short-term plans can reject you outright for a past diagnosis, or write the policy and then deny any claim tied to a condition you had before the start date.
A 2020 study in the journal Health Affairs found that nearly half of short-term plan applications were denied based on medical history.
Many policies cap how much they will pay per day in the hospital, or per year overall.
Some exclude entire categories of care, like chemotherapy or emergency room visits, or require you to pay a separate deductible for each.
A $5,000 hospital bill can turn into a $5,000 problem for you even with the card in your wallet.
Short-term plans were originally limited to three months.
Federal rules stretched that to 364 days, and some states allow renewals that stack up to three years.
But the insurer can still raise your premium at each renewal, or drop you if you get sick.
You do not get the year-long rate lock that a marketplace plan gives you.
For a healthy 26-year-old between jobs, or someone waiting for Medicare to kick in, it can bridge a gap at a fraction of the cost.
The math changes fast once you have a chronic condition, take expensive medication, or plan to start a family.
Run your actual prescriptions through the plan's drug list before you pay a dime.
If you are comparing options, check three things first: whether your doctors are in network, what the annual maximum payout is, and whether pre-existing conditions are excluded.
A cheap plan that covers nothing is not a bargain, it is a bill you did not see coming.
One more move worth making: price a marketplace plan at healthcare.gov before you decide.
Subsidies have gotten more generous, and a bronze plan with real protections may cost less than you assume.
Ten minutes of comparing beats a year of fighting claim denials.
The honest take: short-term coverage is a tool, not a substitute.
It fits a narrow window for healthy people with no ongoing care needs, and it punishes everyone else at the worst possible time.
Final Thoughts
If you buy one, treat it like a temporary patch and set a calendar reminder to get real coverage before it expires.
