Health insurance in America is complicated, expensive, and — after the changes that hit at the end of 2025 — more confusing than it has been in years. Whether you're shopping the ACA Marketplace, checking Medicaid, weighing an employer plan, or aging into Medicare, the decisions you make during enrollment season can swing your annual costs by thousands of dollars. Here is a plain-English map of the options as they stand in 2026.

Open Enrollment and What Changed for 2026

Marketplace open enrollment for 2026 coverage began November 1, 2025. The closing date has historically been January 15 in most states, but federal rules tightened enrollment windows recently and state-run marketplaces set their own deadlines — so treat the date on healthcare.gov as the only one that counts. Outside open enrollment, you can still sign up after a qualifying life event: losing job-based coverage, marriage, divorce, a birth, or a move to a new coverage area. That special enrollment window is generally 60 days, and losing Medicaid also triggers it.

The bigger story is money. The enhanced premium tax credits that Congress created in 2021 — the ones that capped benchmark premiums at 8.5% of income for everyone and made many plans free for lower earners — were scheduled to expire at the end of 2025, and as of early 2026 they had not been renewed. If that lapse stands, subsidies revert to the original ACA schedule: help phases out entirely above 400% of the federal poverty level, and net premiums rise at nearly every income level. Congress can change this mid-year, so verify what credits exist right now on healthcare.gov before assuming last year's price. We break down how the credits are calculated in our Marketplace subsidies guide.

The Metal Tiers, Decoded

Marketplace plans come in four tiers based on how costs split between you and the insurer, on average across all enrollees:

  • Bronze: lowest premiums, highest deductibles; the plan pays roughly 60% of covered costs. Reasonable for healthy people who mainly want protection from catastrophe.
  • Silver: mid-range premiums; the plan pays roughly 70%. The critical detail: cost-sharing reductions — extra help that slashes deductibles and copays for households below 250% of the poverty level — exist only on Silver plans. If your income is in that range, Silver is usually the correct answer, full stop.
  • Gold: higher premiums, lower out-of-pocket costs; the plan pays roughly 80%. Worth pricing if you take regular prescriptions or see specialists.
  • Platinum: highest premiums, plan pays roughly 90%. For people with chronic conditions or planned procedures who will hit their deductible regardless.

In some markets, pricing quirks make Gold plans cheaper than Silver ones. Never assume the tier order matches the price order — compare actual plans.

Medicaid: Check It First

If your household income is at or below 138% of the federal poverty level — around $21,600 a year for an individual under the 2025 guidelines — and you live in one of the 40 states (plus DC) that expanded Medicaid, you may qualify for coverage with zero premium and minimal cost-sharing. Pregnant women, children, and people with disabilities qualify at higher income levels in most states. Marketplace applications automatically route you to Medicaid if you appear eligible, but you can also apply directly through your state agency any day of the year — Medicaid has no enrollment season. Two things to watch in 2026: states re-check eligibility more often than they used to, and work-requirement rules enacted in 2025 are being phased in for some expansion adults. Our Medicaid eligibility guide covers the categories and income rules state by state, and medicaid.gov links to every state agency.

Turning 65? Different System Entirely

Medicare, not the Marketplace, is the path for most people 65 and up, and it runs on its own enrollment clock with real late-enrollment penalties for missing your initial window. If that's you or a parent, start with our Medicare enrollment guide rather than shopping healthcare.gov — keeping a Marketplace plan past Medicare eligibility can get expensive fast.

Employer Coverage and the Family Question

If your employer offers a plan deemed "affordable" under federal rules — meaning your share of the self-only premium stays under an annually set percentage of household income, in the low nine percent range for recent years — you generally can't take Marketplace subsidies instead. Since the "family glitch" fix in 2023, though, affordability for your spouse and kids is measured against the family premium, not just yours: if covering the whole family through work is unaffordable by that test, the family members may qualify for subsidized Marketplace coverage even while you stay on the employer plan. Run both scenarios before open enrollment closes. Also compare deductibles honestly — a high-deductible employer plan paired with an HSA can beat a Marketplace plan for some households, since HSA contributions are tax-deductible and roll over year to year.

For children specifically, don't overlook CHIP: kids in families earning too much for Medicaid often qualify for CHIP at income levels reaching 200-300% of the poverty level or higher depending on the state, with little or no premium — frequently a better deal than adding them to either parent's plan.

Short-Term and Other Limited Plans

Short-term health plans can bridge a gap — between jobs, or while waiting for employer coverage to start. Understand what you're buying: these plans typically exclude pre-existing conditions, can decline to cover maternity or mental health, and may cap total payouts. Federal rules on their maximum duration have flip-flopped across administrations, so the product available in your state in 2026 may look different from what you read about two years ago. The same caution applies to health care sharing ministries and fixed-indemnity plans sold aggressively online: they are not comprehensive insurance, and a single hospitalization can expose you to five-figure bills. Use them as a bridge if you must, never as the plan.

How to Actually Compare Plans

People under 30, and some people with hardship exemptions, can also buy catastrophic plans — very low premiums, very high deductibles, free preventive care. They exist for exactly one situation: protecting a healthy young adult from financial ruin. Note that subsidies can't be applied to them.

Premium is the least useful number on the page. Estimate your total annual cost instead: twelve months of premium, plus your expected doctor visits and prescriptions at each plan's copay levels, plus what happens in a bad year when you hit the deductible and out-of-pocket maximum. A Bronze plan with a $7,500 deductible can cost far more than a Gold plan after one emergency room visit. Then check three lists before enrolling: your doctors in the plan's network directory, your hospital, and every prescription you take in the plan's drug formulary — including its tier, because "covered" at tier 4 can still mean hundreds per fill. If a medication lands on an expensive tier, compare cash prices too; our piece on prescription discount programs explains when paying outside insurance is legitimately cheaper.

Free Help Exists — Use It

Certified navigators and licensed brokers can compare plans with you at no charge; find them through the "Find Local Help" tool on healthcare.gov or by calling 1-800-318-2596. Navigators are grant-funded and don't earn commissions; brokers are paid by insurers but are bound by the same plan data. In our experience, the people who end up in the wrong plan are almost never the ones who asked for help — they're the ones who auto-renewed without looking. Plans change networks, formularies, and premiums every single year, and CMS's own consumer materials at cms.gov say the same thing in politer language. Even if you like your current plan, spend twenty minutes at renewal confirming it still likes you.
