Short-term health insurance is having a moment.
With monthly premiums on ACA marketplace plans up sharply in many states and grocery bills still stubbornly high, a $90-a-month policy with a familiar-sounding name can look like the escape hatch.
It usually isn't, and the fine print is where the trap sits.
These plans are technically "short-term, limited-duration" coverage, originally meant to bridge a gap of a few months between jobs.
Federal rules now let insurers sell them for up to 12 months, and some states allow renewals that stretch the coverage far longer.
They are not required to cover pre-existing conditions, and most can reject you outright if you have one.
A short-term plan can charge you more, or deny a claim entirely, for a condition you already had — even one you didn't know about.
It can also cap how much it pays per year, skip maternity care, skip mental health, skip prescription drugs, and set a lifetime limit.
A single hospital stay can blow past those caps and leave you holding the bill.
The premiums are low because the coverage is thin.
Insurers in this market are allowed to screen applicants, so the healthiest people get in cheap and everyone else pays the price or gets turned away.
That's the opposite of how ACA plans work, where everyone pays a similar rate regardless of medical history and pre-existing conditions are covered.
If you're between jobs, the honest options are usually an ACA marketplace plan, COBRA if you can stomach the cost, or a special enrollment period.
Losing job-based coverage counts as a qualifying life event, which opens a 60-day window to sign up.
Subsidies on marketplace plans can make them cheaper than the sticker price suggests, especially for middle-income households.
There's a real place for short-term plans — a genuine few-month gap, no chronic conditions, and enough savings to absorb a surprise.
If that's you, read the exclusions line by line and check whether your state even allows the longer terms.
For everyone else, the math is a gamble dressed up as a deal.
The monthly savings are visible; the cap that wipes out your savings account is buried in a PDF nobody opens.
Our take: cheap premiums are not the same as cheap care.
Final Thoughts
Before you enroll in anything, calculate the worst-case bill, not the best-case month — that's the number that actually matters.
