Open enrollment season is officially underway for millions of Americans, and if you're like most people, the temptation is to skim the options and keep whatever plan you had last year.
That's a mistake that can quietly cost you hundreds or even thousands of dollars.
Whether you're picking a plan through your employer, Healthcare.gov, or a state marketplace, the choices you make in the next few weeks will lock in your costs for all of 2025.
Here's a practical checklist to work through before the deadline hits. **1.
Check if your doctors are still in network.** Plans shuffle their provider lists every year, and your favorite doctor may have dropped out without any notice to you.
Insurance company directories are often outdated. **2.
Do the math on your prescriptions.** Look up each medication on your plan's formulary, not just the tier number.
A drug that was $30 last year could jump to $200 if it moved to a specialty tier or lost coverage. **3.
Compare the full deductible, not just the premium.** A cheaper monthly payment often comes with a deductible so high you'd pay thousands before coverage kicks in.
Add up premium plus expected out-of-pocket costs for both plans to see the real picture. **4.
Use your FSA or HSA wisely.** Flexible spending accounts are use-it-or-lose-it, so only set aside what you'll actually spend.
Health savings accounts roll over and can be invested, making them more flexible if you have the option. **5.
Don't forget dental and vision.** These are easy to skip, but a single filling or new pair of glasses can cost more than a year of premiums.
If you wear contacts or expect any dental work, run the numbers. **6.
Look at telehealth and mental health coverage.** Many plans now include free or low-cost virtual visits.
If you see a therapist, confirm they're covered under the new plan before you commit. **7.
Watch the deadline.** Most employer plans close in early-to-mid November, while Healthcare.gov runs through January 15 in most states.
Miss the window and you may be stuck waiting until next year unless you qualify for a special enrollment period.
One more thing: if you're self-employed or between jobs, premium tax credits on Healthcare.gov can dramatically lower your monthly cost.
Many people assume they earn too much to qualify, but the income thresholds changed in recent years.
Spend ten minutes entering your estimate before you rule it out.
Scammers also ramp up during open enrollment, so be wary of unsolicited calls or texts promising cheap plans.
Never give your Social Security number to someone who contacts you first.
Go directly to Healthcare.gov or your employer's benefits portal. **The bottom line:** Open enrollment isn't a formality.
It's one of the few times each year you can meaningfully change what you pay for healthcare.
An hour of comparison shopping now can save you real money every month for the next twelve months.

Set a reminder, gather your medication list, and treat it like the financial decision it actually is.
