Open enrollment for 2026 health coverage is nearly here, and the window is shorter than most people assume.
For plans sold on HealthCare.gov, the period runs Nov. 1 through Jan. 15 in most states.
If you get insurance through an employer, your HR department sets the dates, and they often close in just two weeks.
Miss the deadline without a qualifying life event, and you may be locked out of new coverage until 2027.
The bigger risk is auto-renewing into a plan that quietly got more expensive.
Premiums are projected to climb again for 2026, with some insurers requesting double-digit increases.
So treat this like a grocery run: compare prices, check what is actually in the cart, and do not just grab the same thing off the shelf. **1.
Check whether your doctors and drugs still count.** Insurer networks change every year.
A hospital or physician that was in-network last year can drop out.
Pull up your plan's provider directory and confirm each doctor, then run every prescription through the formulary. **2.
Add up the real cost, not just the premium.** The monthly bill is only part of it.
Look at the deductible, copays, coinsurance and out-of-pocket maximum.
A cheaper premium often means you pay thousands more before coverage kicks in. **3.
Estimate your actual usage.** If you are healthy and rarely see a doctor, a high-deductible plan paired with an HSA can make sense.
If you manage a chronic condition or expect surgery, a lower deductible usually wins even at a higher monthly cost. **4.
Use the plan comparison tool.** HealthCare.gov and most state exchanges let you enter income, doctors and medications to see side-by-side totals.
It takes 20 minutes and often surfaces savings people miss by guessing. **5.
Recheck your subsidies.** Enhanced ACA subsidies have been a moving target in Congress, and income changes can swing your tax credit either way.
If you earn more this year, update your estimate or you may owe money at tax time. **6.
Look at the HSA and FSA options.** Open enrollment is usually the only time you can start or change a health savings account or flexible spending account.
FSAs are use-it-or-lose-it, so only set aside what you will realistically spend. **7.
Confirm your enrollment went through.** After submitting, log back in and screenshot the confirmation.
Errors and dropped applications do happen, and catching one in November beats discovering it in January.
One more thing worth knowing: if you are offered affordable employer coverage, you generally cannot claim ACA subsidies on the marketplace.
That single rule trips up a lot of filers every spring.
Dental and vision often ride along with the same enrollment window, so handle everything in one sitting.
Set a calendar reminder for two weeks before your deadline, not the day of.
Our take: the people who save the most during open enrollment are not the ones who find the cheapest plan.
They are the ones who spend an hour doing the math before the clock runs out.

A little homework now can mean hundreds of dollars back in your pocket next year.
