A short-term health insurance plan can look like a lifesaver when you're between jobs, waiting on Medicare, or staring down a $700 monthly COBRA bill.
Premiums for these plans often run $100 to $300 a month for an individual, a fraction of what an Affordable Care Act marketplace plan costs without a subsidy.
That price gap is exactly why enrollment in short-term plans has climbed for years.
Under federal rules, short-term plans can last up to 364 days and be renewed for up to three years total, depending on your state.
They don't have to cover pre-existing conditions, prescription drugs, maternity care, or mental health treatment.
Insurers can also ask about your health history and reject you outright.
That means a plan that costs $150 a month may pay nothing if your diagnosis traces back to something in your medical records.
Consumers have reported denials for issues as common as acne medication, past injuries, or a single elevated lab result.
The savings are real, but so is the gap between what you think you bought and what actually gets paid.
State rules matter more than the brochure.
Some states, including California, New York, and Massachusetts, ban or heavily restrict these plans.
Others allow the full three-year duration.
Before you buy, check your state insurance department's website to see what's permitted where you live and whether the carrier is licensed there.
If you're comparing options, run the math beyond the premium.
Add up your deductible, out-of-pocket maximum, and what a single hospital stay would cost you.
A $10,000 deductible on a $200 plan can wipe out the savings of a marketplace plan in one emergency.
Also check whether you qualify for subsidies on HealthCare.gov.
Roughly 4 out of 5 marketplace enrollees get financial help, and many people find coverage cheaper than they assumed once the tax credit is applied.
Special enrollment periods are another path.
Losing a job, moving, getting married, or having a baby typically opens a 60-day window to sign up for ACA coverage outside the usual open enrollment.
Missing that window is the main reason people turn to short-term plans in the first place, so mark the date the moment your coverage ends.
If you do buy short-term coverage, treat it as a bridge, not a home.
Set a calendar reminder for 30 days before it expires, and use that time to line up something more durable.
Read the exclusions page line by line, and call the insurer to ask directly whether a specific condition or medication you use is covered.
Our take: short-term plans aren't a scam, but they're also not a substitute for real coverage, and the marketing rarely makes that clear.
If you're healthy, temporarily uninsured, and clear on the limits, a bridge plan can save you real money.
Final Thoughts
If you have any ongoing condition, the cheap premium is often a bet you'll lose at the worst possible moment.
