Open enrollment season is in full swing for millions of Americans covered through an employer, the Health Insurance Marketplace, or Medicare.
It's also the one time of year when a few minutes of clicking can save you hundreds of dollars next year — or cost you if you rush.
Plans change every year, even if you don't.
If you do nothing, most people get rolled into their current plan or a similar one, and the price can jump without you noticing.
Premiums, deductibles, and copays get reset each January, so last year's numbers tell you almost nothing about this year's.
First, check whether your doctors and hospitals are still in network.
Insurers renegotiate contracts constantly, and a plan that covered your doctor in 2024 may not in 2025.
Call the office directly — don't trust a directory that was updated months ago.
If you take regular prescriptions, run each one through the plan's formulary before you commit.
A drug that cost $30 could land in a higher tier and cost $300.
Second, add up more than the monthly premium.
A cheap premium often hides a deductible of $5,000 or more.
If you'd struggle to cover that in a bad year, a slightly higher premium with a lower deductible may be the better deal.
Look at the out-of-pocket maximum too, since that's your true worst-case number.
Open enrollment is usually when you elect flexible spending dollars, and that money generally doesn't roll over.
Estimate what you'll actually spend on copays, dental, vision, and prescriptions — then round down, not up.
With an HSA, check whether your employer contributes and whether your plan lets you invest the balance.
Fourth, don't ignore dental, vision, and life insurance add-ons.
They're often cheap during open enrollment and expensive to buy later.
If you have kids in braces or wear glasses, the math usually favors enrolling.
Fifth, if you're on Medicare, compare your Part D drug plan every single year.
Formularies shift, and the plan that was cheapest for you last year is often not the cheapest now.
The same goes for Medicare Advantage networks.
Sixth, if you buy coverage on the Marketplace, recheck your subsidy.
Income changes, household changes, and updated federal rules can move your premium a lot.
Log in, update your income estimate, and compare at least three plans side by side rather than letting the site default you.
Seventh, mark the deadline in your phone.
Most employer open enrollment windows run just two to three weeks, and Marketplace open enrollment typically closes in mid-January in most states.
Miss it and you may be locked out until next year unless you qualify for a special enrollment period.
The takeaway is simple: this isn't a form to speed through.
Thirty minutes with your last few months of medical bills and a calculator can beat any generic advice.
Final Thoughts
Treat open enrollment like a yearly money checkup, because that's exactly what it is.
