When you can sign up, and what help you might qualify for.
- Open Enrollment
- The yearly window when anyone can start, switch or drop a Marketplace plan.
- Special Enrollment Period (SEP)
- A window outside Open Enrollment that opens after certain life events — losing coverage, moving, marriage, a new baby.Usually 60 days from the event. Miss it and you may have to wait for Open Enrollment.
- Qualifying life event
- The change that opens a Special Enrollment Period for you.
- Premium tax credit (subsidy)
- Help from the government paying your monthly premium, based on your household income and size.It's usually applied straight to the premium, so you see a smaller bill rather than waiting for tax time.
- Cost-sharing reduction
- Extra help that lowers your deductible, copays and out-of-pocket maximum. Only available on Silver plans, and only at certain income levels.
- Effectuation
- Your carrier switching the policy on, which normally happens once the first premium is paid.Enrolled and effectuated are not the same thing. Until the first payment clears, you're enrolled but not yet covered.
- Minimum essential coverage
- Coverage that counts as real health insurance under the law — a job plan, Medicare, Medicaid, or a Marketplace plan.Losing it is what opens a Special Enrollment Period. Short-term or discount plans usually don't count.
- Data matching issue (DMI)
- The Marketplace couldn't match something on your application — income, citizenship, a Social Security number — against its own records, so it asks for a document.There's a deadline, and missing it can cost you coverage or your subsidy. Anything we need from you shows up in your portal.
