Open enrollment is here, and if you treat it like a quick box to check, you could leave hundreds—or thousands—of dollars on the table.
Most employer plans let you switch once a year, and the window usually slams shut in mid-December.
Miss it and you're locked into your current coverage until next fall.
The tricky part is that "doing nothing" isn't neutral anymore.
Premiums, deductibles, and drug formularies shift every year, so the plan you picked last year may quietly cost more now.
Here's a practical checklist to run through before your deadline. **Start with last year's actual costs, not the brochure.** Pull your Explanation of Benefits statements and add up what you really paid in premiums, copays, and coinsurance.
That real number beats any "low premium" pitch.
A cheaper monthly plan with a high deductible can cost more overall if you see specialists or take regular medication. **Check whether your doctors and drugs are still covered.** Insurers renegotiate networks every year, and a hospital or physician that was in-network can drop out.
Look up each provider and every prescription on your plan's current formulary, then compare it to the options you're being offered.
One dropped drug can mean hundreds in out-of-pocket costs. **Compare the total, not the paycheck deduction.** Add your annual premium to your deductible and your expected out-of-pocket max.
That combined figure is the honest price of each plan.
If you're generally healthy, a high-deductible plan paired with an HSA can make sense—but only if you can cover the deductible if something goes wrong. **Use the free money if it's offered.** If your employer matches HSA contributions or funds an FSA, that's cash you forfeit by not enrolling.
Just remember FSA money is usually "use it or lose it" by year-end, while HSA balances roll over and can be invested. **Don't forget the freebies.** Many plans quietly cover things like telehealth visits, preventive screenings, and generic prescriptions at no cost.
Skipping them means paying out of pocket for care you already funded. **Look beyond medical.** Dental, vision, disability, and life coverage often ride along in the same enrollment window.
If you have dependents or a mortgage, term life and disability are worth a hard look—they're frequently cheaper through an employer than on the open market. **Double-check your beneficiaries and dependents.** Life changes—marriage, a new baby, a divorce—are exactly when people forget to update who gets what.
It takes five minutes and prevents real headaches later.
If you're self-employed or between jobs, the federal marketplace at Healthcare.gov has its own open enrollment window, typically November 1 through January 15, with coverage starting January 1 if you sign up by December 15.
State-run exchanges may have different dates, so check yours.
The bottom line: an hour of comparing plans now can beat a year of surprise bills.
Set a calendar reminder, gather your documents, and run the numbers before the deadline—not after.

Your future self, staring at a medical bill in March, will thank you.
