Open enrollment is the one time each year most Americans can change their health insurance, and it's easy to let it slide until the deadline sneaks up.
Miss the window, and you're generally locked into your current plan until next year.
Here's a practical checklist to make sure you don't leave money or coverage on the table.
Most employer plans wrap up in November or early December, while Affordable Care Act marketplace enrollment typically runs from November 1 through January 15 in most states.
A handful of states run their own exchanges with different cutoffs, so check your state's site rather than assuming.
Next, add up what you actually spent this year.
Pull your receipts for copays, prescriptions, dental work, and urgent care visits.
If you blew past your deductible in September, a lower-deductible plan might pencil out better than the cheap one you picked last year.
Then check whether your doctors and medications are still covered.
Formularies and networks change every year, even if the plan name stays the same.
A drug that cost you $15 in January can jump to $150 in January if it moved to a higher tier.
Don't overlook the tax-advantaged accounts tied to your plan.
If you have a high-deductible plan, an HSA lets you set aside pre-tax money for medical costs, and the funds roll over year to year.
A flexible spending account can save you money too, but use-it-or-lose-it rules usually apply, so estimate carefully.
Compare the total annual cost, not just the premium.
A plan with a low monthly payment can cost you far more once you factor in the deductible, coinsurance, and out-of-pocket maximum.
Add those numbers up for each option and compare the worst-case totals side by side.
If you're married or have kids, review who's on which plan.
Sometimes it's cheaper to split the family across two employer plans, and sometimes staying together wins.
Finally, double-check your personal info on file.
A wrong address, an outdated income estimate, or a missing dependent can delay your coverage or cost you a subsidy.
A few extra minutes now can save you hundreds of dollars and a lot of stress later.
My take: most people treat open enrollment like a formality and just re-up whatever they had last year.
That's usually a mistake, because plans quietly change while your needs do too.
