Open enrollment season is back, and for millions of Americans with employer coverage, the window to pick next year's health plan runs just a few weeks.
Miss it, and you're typically locked into your current choice until next fall.
That's a full year of premiums, copays, and deductibles decided in a single sitting.
Health care costs continue climbing, and many employers are passing more of the tab to workers through higher deductibles and coinsurance.
Meanwhile, premiums for benchmark ACA marketplace plans are set to rise sharply in many states in 2026.
Whether your coverage comes from a job or healthcare.gov, the math deserves more than a five-minute click-through.
Here's a practical checklist to run before you hit submit. **Compare total costs, not just premiums.** A plan with a lower monthly premium can cost far more if you use care regularly.
Add up the premium, deductible, copays, and out-of-pocket maximum across the plans you're considering — then estimate your actual usage for the year.
If you're generally healthy, a high-deductible plan paired with an HSA can make sense.
If you take expensive medications or expect a procedure, the math often flips. **Check whether your doctors and hospitals are still in network.** Insurers renegotiate contracts constantly, so the plan that covered your doctor last year might not next year.
Look up every provider you rely on, including specialists and your preferred hospital, directly in the plan's directory.
Calling the insurer to confirm is worth the ten minutes. **Review your prescriptions against the formulary.** Drug coverage changes more than people expect.
A medication that cost $30 last year could jump to a few hundred if it moves to a different tier.
Check each drug by name and dosage, and ask whether prior authorization or step therapy now applies. **Don't sleep on FSAs and HSAs.** If you have a flexible spending account, it's use-it-or-lose-it for most people, so set your contribution based on realistic expenses — not the maximum.
Health savings accounts, by contrast, roll over year to year and can be invested, making them one of the more tax-friendly accounts available to households. **Look at disability and life coverage while you're in there.** Many employers let you buy supplemental coverage at group rates during the same window.
If you have dependents or a mortgage, it's worth pricing. **If you're on Medicare, your window looks different.** Medicare open enrollment runs October 15 through December 7, and standalone drug plans can change their formularies and premiums every year.
Re-shop Part D and Medicare Advantage plans annually rather than letting them auto-renew. **Finally, check your beneficiaries and dependent info.** Marriages, births, and address changes are easy to forget, and outdated records can cause claims headaches later.
The bottom line: open enrollment rewards a little homework.
Set aside an hour, gather your bills and medication list, and run the numbers before the deadline — not after.
