Health insurance open enrollment gets all the attention, but there's a parallel market that quietly runs year-round: short-term health plans.
These policies are marketed hard on social media and search ads, often promising premiums that look like a fraction of what you'd pay for an Affordable Care Act plan.
For a healthy 30-year-old, a short-term policy might quote $80 to $150 a month, while a marketplace plan in many states runs $300 or more before subsidies.
That price gap is real, and it's the whole pitch.
What the ads tend to skip is what you're giving up.
Short-term plans, which the Trump administration expanded in 2018 to allow terms of up to 364 days, don't have to cover pre-existing conditions, prescription drugs, maternity care, or mental health treatment.
They also aren't required to cap your annual out-of-pocket costs, which means a single hospital stay could leave you with a bill in the tens of thousands.
Consumer complaints have piled up for years.
State regulators and news investigations have found cases where people bought a plan believing it was comprehensive coverage, then discovered their cancer treatment or surgery wasn't covered.
In 2023, the Biden administration proposed a rule to limit these plans to three months and require clearer warnings, though the final version and its legal status have been tangled up in court ever since.
The honest answer is a narrow slice of people: those between jobs who need a bridge of a few months, early retirees waiting for Medicare at 65, or gig workers with no employer coverage who are healthy and mainly want protection against a random accident.
Even then, a catastrophic ACA plan with a high deductible may cost more per month but comes with real guardrails, including a cap on what you can be billed in a year.
If you're shopping, a few habits will save you real money and grief.
First, check whether the plan is "ACA-compliant" — if it isn't, pre-existing conditions are fair game.
Second, read the exclusions list before you look at the premium, not after.
Third, check the deductible and the out-of-pocket maximum separately; some short-term plans have no maximum at all.
And fourth, price out a marketplace plan with subsidies at Healthcare.gov, because a large share of households qualify for tax credits that shrink the gap more than they expect.
Losing job-based coverage counts as a qualifying life event, which opens a 60-day window to enroll in a marketplace plan outside of open enrollment.
That window is often the best deal available, and it closes whether or not you were paying attention.
One more thing worth knowing: short-term plans can and do deny renewal if you get sick.
A policy that costs $120 a month is a bargain right up until the moment you actually need it, and that's precisely when it can disappear.
The appeal here is understandable — premiums have climbed fast, and a cheaper option feels like relief.
But insurance is one of the few purchases where the sticker price tells you almost nothing about the value.
Final Thoughts
If you go the short-term route, go in with your eyes open, treat it as a temporary patch rather than real coverage, and put the savings toward a medical emergency fund.
