Open enrollment season is in full swing, and if you're like most Americans, you're probably planning to glance at your options, pick something close to last year's plan, and move on.
That approach can quietly cost you hundreds or even thousands of dollars.
Whether you're signing up through your employer or browsing Healthcare.gov, a few minutes of comparison shopping can change your whole year.
Here's what to actually check before you hit submit. **1.
Verify your doctors are still in-network.** Insurance networks change every single year, and a doctor who took your plan in 2024 may not take it in 2025.
Call the office directly — don't trust the insurer's online directory, which is often outdated. **2.
Check your prescriptions, not just the plan's drug list.** Formularies get reshuffled annually.
A medication that cost $15 last year could jump to a tier that costs $150.
Look up each drug by name and dosage on the plan's formulary before you commit. **3.
Do the math on deductibles versus premiums.** A cheaper monthly premium often comes with a much higher deductible.
If you expect any real medical care next year, add up the premium plus your likely out-of-pocket costs for each plan — the "cheap" option frequently loses. **4.
Don't forget the FSA and HSA deadlines.** If you're contributing to a flexible spending account, that money usually doesn't roll over.
Estimate carefully, because you generally forfeit what you don't spend.
Health savings accounts are different — they're portable and can grow over time, so maxing one out can pay off later. **5.
Confirm your plan still covers your kids.** Dependent coverage rules vary, and a child who ages out or changes student status can slip through the cracks.
Double-check who's actually listed before the window closes. **6.
Watch for auto-renewal traps.** Many plans automatically re-enroll you in the same or a similar option.
That sounds convenient, but it means you could get rolled into a plan with a new network or higher costs without ever comparing alternatives. **7.
Look beyond the sticker price at total costs.** Copays, coinsurance, out-of-network rates, and emergency room rules all matter.
A plan with a low premium and brutal coinsurance can sting badly after one unexpected hospital visit.
A few practical reminders: employer open enrollment windows are often just two to three weeks, and missing yours typically means waiting until next year unless you have a qualifying life event.
If you're buying on the federal marketplace, mark the December 15 deadline for coverage starting January 1.
It's also worth checking whether you qualify for subsidies this year — income changes, a new dependent, or a job shift can all affect what you're eligible for.
Many people leave money on the table simply because they assume they won't qualify. **The bottom line:** Treat open enrollment like a 30-minute money task, not a formality.
Comparing two or three plans side by side, verifying your doctors and drugs, and checking your account contributions can save you real money — and a lot of stress when you actually need care.
Final Thoughts
The window is short, so knock it out this week rather than the night before the deadline.
