Open enrollment only comes around once a year, and picking wrong can mean paying for coverage that doesn't cover what you actually need — or missing the window entirely. This walks you through it in order, from figuring out your dates to making sure your new plan actually kicked in.

## Before You Start Comparing

- [ ] Find your exact enrollment window `{essential}`
  Marketplace open enrollment usually runs Nov 1 to Jan 15 (a few states set their own dates), and employer windows are set by HR — miss it and you're usually locked out until next year unless you have a qualifying life event.
- [ ] Check if a life event gives you a special enrollment window instead `{when: life-event}`
  Marriage, birth, job loss, or moving can open a 60-day window outside the normal period.
- [ ] List everyone who needs coverage — spouse, kids, dependents
- [ ] Pull last year's plan documents and note what you paid in premiums, deductible, and total out-of-pocket
- [ ] List every doctor, specialist, and hospital you actually used this year
- [ ] List every prescription you take regularly, including dosage
- [ ] Think through any planned care next year — surgery, pregnancy, ongoing therapy
  Since that changes what "good coverage" means for you.
- [ ] Gather income and household info if using the Marketplace `{when: using-marketplace}` `{essential}`
  Marketplace subsidies are based on estimated household income, and getting it wrong means repaying the difference at tax time.

## Comparing Your Options

- [ ] Check your current plan's renewal terms and default option
  Doing nothing usually just re-enrolls you in whatever's changed for next year.
- [ ] Compare monthly premiums across plans, but don't stop there
- [ ] Compare the deductible — what you pay before insurance kicks in
- [ ] Compare the out-of-pocket maximum — the real ceiling on a bad year
- [ ] Confirm your doctors and hospitals are in-network for each plan you're considering `{essential}`
  Networks change yearly even if the plan name stays the same.
- [ ] Check each plan's drug formulary for your specific medications and their tier/cost
- [ ] Compare copays and coinsurance for the visits you actually use — urgent care, specialists, ER
- [ ] Weigh a high-deductible plan only if you can afford the deductible in an emergency `{when: considering-high-deductible-plan}`
  A low premium isn't a deal if you can't cover a bad month.
- [ ] Check if a high-deductible plan qualifies you for an HSA, and note the yearly contribution limit if so
- [ ] Look up the plan's member satisfaction or quality rating if the Marketplace or your employer provides one
- [ ] Add up premium plus expected deductible/copay costs for a realistic full-year estimate
  Not just the sticker premium.

## Enrolling

- [ ] Submit your enrollment before the deadline `{essential}`
  Late submissions are generally not accepted outside a special enrollment period.
- [ ] Double-check every dependent is listed correctly `{essential}`
  A typo or omission can leave a family member uninsured until next year.
- [ ] Make your first premium payment if required to activate coverage `{when: marketplace-plan}` `{essential}`
  Selecting a plan isn't the same as being enrolled.
- [ ] Update your payroll deduction elections if enrolling through an employer `{when: employer-plan}`
- [ ] Save your confirmation number and a copy of the plan summary

## After You're Enrolled

- [ ] Log back in about a week or two later to confirm the enrollment actually processed
- [ ] Watch for your new insurance card and digital ID in the mail or app
- [ ] Give your doctors' offices your new insurance info before your next visit
- [ ] Note your new plan's start date and any gap in coverage to plan around
- [ ] Set a calendar reminder a few weeks before next year's open enrollment
  So you're not scrambling again.
