Open enrollment letters are landing in mailboxes and inboxes right now, and the pitch sounds familiar: a lower monthly premium if you agree to a higher deductible.
For millions of American workers, that trade-off looks like an easy win on paper.
A high deductible health plan, or HDHP, is exactly what it sounds like.
You pay less per paycheck, but you cover a much larger chunk of your medical costs before insurance kicks in.
For 2025, the IRS sets the minimum deductible at $1,650 for individual coverage and $3,300 for families, with out-of-pocket maximums capped at $8,300 and $16,600 respectively.
It's what happens when you actually need care before you've hit that number.
Say you tear a ligament playing pickup basketball.
An ER visit, imaging, and a specialist follow-up can easily run $3,000 to $5,000.
On an HDHP, that entire bill lands on you until you cross your deductible threshold.
A coworker on a traditional plan might pay a $250 copay and move on with their week.
This is why HDHPs have become the default at many employers.
Premiums for family coverage have climbed past $25,000 a year, according to KFF's annual survey, and companies have shifted more of that cost onto workers through higher deductibles.
There's a silver lining worth knowing about.
Most HDHPs are paired with a health savings account, or HSA, which lets you set aside pre-tax money for medical expenses.
Unlike a flexible spending account, HSA funds roll over year after year and can be invested.
Used strategically, an HSA can soften the blow of a high deductible — but only if you fund it.
The math gets uncomfortable for people who skip that step.
A 2024 survey from the Employee Benefit Research Institute found that many workers don't have enough cash on hand to cover even a modest deductible.
That means a single unexpected diagnosis could turn into credit card debt.
Before you click "enroll," run three numbers.
First, add up your expected medical costs for the year — prescriptions, therapy, regular checkups, anything predictable.
Second, compare total annual premiums plus that expected spending across both plan options.
Third, check whether your employer funds an HSA and how much.
The plan with the lower sticker price often loses once you do the arithmetic.
Also watch the fine print on what's covered before the deductible.
Many HDHPs cover preventive care at no cost, thanks to the Affordable Care Act, but specialists and urgent care usually aren't included.
A plan that looks cheap in January can feel very different in July.
Our take: an HDHP can be a smart tool for healthy people who max out an HSA and have an emergency fund to lean on.
For anyone managing a chronic condition or living paycheck to paycheck, the lower premium may be a mirage.

Read the summary of benefits carefully, and don't let a slick enrollment portal make this decision for you.
