Open enrollment season is officially underway for millions of Americans, and the stakes are higher than usual.
Premiums, deductibles, and out-of-pocket maximums have all shifted for 2025, and the plan that worked for you last year may quietly cost you more this time around.
The first mistake people make is auto-renewing without checking anything.
Insurers adjust networks, drug formularies, and copays every single year.
A doctor you love could be out of network in January, or a prescription you take daily might move to a higher tier.
Start with one number: your total expected cost, not just the monthly premium.
Add up premiums for the year, then factor in your deductible and what you typically spend on care.
A cheaper monthly plan with a sky-high deductible can end up costing thousands more if you actually use it.
Next, verify your providers are still in network for the coming year.
Call the insurer directly rather than trusting a directory that may be outdated.
If you take regular medications, check each one against the plan's formulary and confirm whether it needs prior authorization.
Don't overlook the accounts that pair with your plan.
A health savings account, if you qualify, offers a triple tax advantage and rolls over year to year.
A flexible spending account lowers your taxable income but usually expires, so only fund it with money you're confident you'll spend.
If you're on Medicare, the open enrollment window runs through December 7, and Advantage plan networks change frequently.
Compare your current plan against at least two alternatives using the official Medicare plan finder, and pay attention to whether your pharmacy is still in the preferred network.
For marketplace coverage, subsidies can shift based on your projected income.
If your earnings changed this year, update them, because an inaccurate estimate can mean a smaller credit or a surprise bill at tax time.
Marketers flood inboxes and mailboxes this time of year with plans that look cheap up front.
Some are short-term policies that exclude pre-existing conditions and cap payouts.
Read the fine print before clicking, and never share your Medicare or Social Security number with an unsolicited caller.
Set a calendar reminder about two weeks before your deadline so you're not deciding in a panic.
Gather your list of medications, doctors, and last year's claims, then run the numbers side by side.
An hour of comparing now can save real money later. **The bottom line:** Treat open enrollment like a yearly financial checkup, not a formality.
The plan you ignore is often the one that quietly raises your costs.
Final Thoughts
Compare, verify, and choose deliberately.
