Open enrollment season is officially underway for millions of Americans, and if you're like most people, the instinct is to skim the options, pick something that looks roughly like last year's plan, and move on with your life.
That instinct could be costing you real money.
Premiums, deductibles, and networks shift every single year.
A plan that made sense for your family in 2024 might be a bad fit now, especially if your income changed, your medications changed, or your doctor dropped off a network.
Here's a practical checklist to run through before you hit submit. **1.
Compare the total cost, not just the premium.** A low monthly premium means nothing if the deductible is $8,000 and you actually use your insurance.
Add up premiums for the year plus your expected out-of-pocket costs.
Check if your doctors and hospitals are still in-network.** Networks change quietly.
Call your doctor's office or check the insurer's provider directory directly — don't assume last year's coverage carries over. **3.
Verify your prescriptions are covered.** Look up each medication on the plan's drug formulary.
A drug that cost $30 last year could jump to $300 if it moves to a different tier or requires prior authorization. **4.
Look at the deductible versus your real life.** If you rarely see a doctor, a high-deductible plan paired with an HSA can work well.
If you have ongoing conditions, a higher premium with a lower deductible often wins. **5.
Don't forget dental, vision, and life insurance.** These are often separate elections during open enrollment.
If you skip them, you may be waiting another year — or paying full price out of pocket. **6.
Check dependent care and FSA deadlines.** Flexible spending accounts let you set aside pre-tax money, but the funds usually expire.
Overfunding an FSA means losing money you can't get back. **7.
Review your beneficiaries.** If you got married, had a kid, or went through a divorce this year, your beneficiary designations may be outdated.
It takes two minutes to fix and prevents real headaches later.
One more thing worth doing: read the summary of benefits coverage document.
It's a standardized, plain-English sheet that every plan is required to provide.
It breaks down costs in a way the marketing brochures won't.
If you're on Medicare, your open enrollment window runs through December 7, and the same checklist applies — especially the drug formulary and network checks.
For workplace plans, most deadlines land in November or early December, so don't wait until the last week.
The bottom line: open enrollment isn't a formality.
It's one of the few times a year you have real control over your health care costs, and 20 minutes of comparison shopping can save you hundreds — sometimes thousands — over the next twelve months.

Set a calendar reminder, grab your last pay stub and your medication list, and treat it like the money decision it actually is.
