Open enrollment season is officially underway for millions of Americans, and if you're tempted to just click "keep my current plan" and move on, you're not alone.
But that autopilot decision can quietly cost you hundreds — sometimes thousands — of dollars a year.
Whether you get coverage through your employer, the ACA marketplace, or Medicare, the rules have shifted enough this year that a fresh look is worth your time.
Here's a practical checklist to run through before your deadline hits. **1.
Check your deadline — it's not the same for everyone.** Employer plans typically lock in during a two-to-three week window in late October or November.
ACA marketplace open enrollment runs November 1 through January 15 in most states, though some state-run exchanges have different dates.
Medicare's window closed December 7, but Medicare Advantage and Part D have their own separate period through December 7 as well.
Miss it and you may be stuck waiting a full year. **2.
Compare your premium against your deductible — not just one or the other.** A low monthly premium feels great until you actually need care.
Run the math on a worst-case scenario: premium plus out-of-pocket maximum.
That combined number tells you what you'd actually pay in a bad year, which matters more than the sticker price. **3.
Confirm your doctors and medications are still covered.** Insurers tweak their networks every year.
A doctor who was in-network in January might be out by January.
Same goes for prescriptions — check the formulary for every drug you take, including generics, because tier placement can change without warning. **4.
Use an HSA if you have one — it's triple tax-advantaged.** If your plan qualifies, contributions go in pre-tax, grow tax-free, and come out tax-free for medical costs.
For 2024, the limits are $4,150 for individuals and $8,300 for families.
That's real money you can invest and let compound for decades. **5.
Don't ignore dental and vision.** These get skipped constantly because they feel like small potatoes.
But a single crown or a pair of prescription glasses can run into the hundreds out of pocket.
If you know you'll need either, the add-on often pays for itself. **6.
Watch for spousal surcharges and wellness incentives.** Many employers now charge extra if your spouse has access to coverage elsewhere.
On the flip side, some plans knock money off your premium if you complete a health screening or a wellness program.
Read the fine print — free money is rare, but it exists here. **7.
Recheck your beneficiaries and dependent info.** Life changes — marriages, divorces, new kids, kids aging off your plan at 26.
A five-minute review prevents a paperwork nightmare later.
If you're on the ACA marketplace, also re-enter your income estimate.
Subsidies are based on projected income, and if yours shifted, your tax credit may have too.
Getting that wrong can mean owing money back at tax time.
The bottom line: open enrollment isn't a formality, it's one of the few times a year you get to renegotiate your health costs.
An hour of comparison shopping now can beat a year of regret later.
