Open enrollment season is officially underway for millions of Americans, and this year the stakes feel higher than usual.
Premiums, deductibles, and out-of-pocket caps have all shifted, and if you let your current plan auto-renew without a second look, you could be leaving hundreds—sometimes thousands—of dollars on the table.
Roughly 24 million people buy coverage through the ACA marketplaces, and most have until mid-January to lock in a plan for 2025.
The single biggest mistake is doing nothing.
Auto-renewal feels safe, but insurers tweak networks, drug formularies, and copays every year.
A plan that worked for you last year might now exclude your doctor or charge more for a prescription you take monthly.
Spend 30 minutes with your options before the deadline, not after.
Start with your total expected costs, not just the monthly premium.
A low premium often hides a high deductible, which means you pay more out of pocket before coverage kicks in.
Add up premiums, your deductible, and copays for regular care, then compare that full number across at least three plans.
Check that your doctors and hospitals are still in-network.
Provider directories change quietly, and a favorite specialist can drop out between plan years.
Call the office directly and ask which plans they'll accept in January—relying on the insurer's website alone can backfire.
If you take a brand-name drug, confirm it's still on the formulary and at what tier.
A medication moving from tier two to tier three can add real money over a year.
Ask your pharmacist which plans cover your exact dose at the lowest cost.
Don't skip dental, vision, and life insurance if your employer offers them.
These are often cheaper through work than buying standalone, and open enrollment is frequently the only window to add them without a medical review.
If you have dependents, revisit your life coverage—a growing family usually needs more than the default.
If you're on a marketplace plan, double-check whether you still qualify for subsidies.
Income changes, a new job, or a side gig can shift your premium tax credit up or down, and getting it wrong means settling up at tax time.
State navigators, licensed brokers, and your HR benefits team cost you nothing and often spot savings you'd miss.
Set a calendar reminder for your deadline now—missing it can leave you uninsured until next year.
The bottom line: open enrollment rewards the people who actually sit down and read the fine print.
