If you get health insurance through your job, the paperwork sitting in your inbox right now could cost you more than you expect.
Open enrollment season is here, and roughly half of workers with employer coverage are being steered toward high deductible health plans, or HDHPs.
They usually come with the lowest monthly premium, which is exactly why they get picked so often.
The average deductible for a single person in an HDHP now runs about $1,700, according to KFF's annual employer survey, and family coverage can top $3,300.
That's the amount you pay out of pocket before most coverage kicks in, on top of your premium.
A short hospital stay or an ER visit can wipe out your entire emergency fund before the insurance company pays a dime.
If your employer chips money into a health savings account, or HSA, that cash is yours to keep, rolls over every year, and grows tax-free if you invest it.
Many companies also cover a chunk of preventive care, like annual physicals and screenings, before you've met the deductible.
For healthy people who rarely see a doctor, the lower premium plus free HSA money can genuinely come out ahead.
The trap is what happens when you actually get sick.
Most HDHPs only cover preventive care before the deductible, so a specialist visit, an urgent care trip, or a prescription refill can land on your bill in full.
One broken arm can mean $3,000 or more out of pocket.
The people hurt most are those with chronic conditions, prescriptions, or kids who play sports.
Before you click "accept," do three things.
First, add up your total yearly cost, not just the premium: monthly premium times twelve, plus the deductible, plus any expected copays.
Second, check whether your employer contributes to an HSA and how much.
Third, list every medication and regular appointment your family actually uses, then price it out under each plan.
A plan with a $40 higher premium can easily save you thousands if you use care regularly.
One more deadline worth knowing: if you want an HSA for next year, you usually have to enroll in the HDHP during open enrollment.
Miss the window and you're locked out until next fall, unless you have a qualifying life event like a marriage, a birth, or a job change.
Our take: HDHPs aren't a scam, but they're sold as a simple cost-saver when they're really a bet that you won't get sick.
Final Thoughts
Run your own numbers instead of trusting the default option, because the cheapest premium on the sheet is rarely the cheapest plan for your family.
