What the Affordable Care Act does
The ACA was signed into law in March 2010. Its reforms include health insurance Marketplaces, consumer protections and coverage standards. Marketplace plans cover essential health benefits and cannot deny coverage or charge more because of a pre-existing condition.
Availability, premiums and financial assistance depend on where you live, your household and current rules. Do not assume a plan is free or that an earlier year’s subsidy calculation still applies.
What to compare in a health plan
| Consideration | Why it matters |
|---|---|
| Premium | Your monthly payment after any eligible assistance. |
| Deductible and cost sharing | What you pay before and after the plan begins sharing covered costs. |
| Doctors and hospitals | Check the exact network and out-of-network rules. |
| Prescriptions | Confirm medications, tiers, pharmacy access and prior authorization. |
| Yearly out-of-pocket limit | The limit for qualifying covered costs, usually within the network; premiums are separate. |
| Household needs | Consider dependents, expected care and access to employer coverage. |
Enrollment and financial assistance
You generally enroll during Marketplace Open Enrollment or a Special Enrollment Period after a qualifying event. State-based Marketplaces can have different dates and processes. Use HealthCare.gov or your state Marketplace to confirm current deadlines.
Premium tax credits and other assistance depend on eligibility and current law. Report household or income changes to the Marketplace. Medicaid and CHIP can have year-round enrollment for people who qualify.
If you are approaching Medicare eligibility
Marketplace coverage is not a Medicare Supplement. Once you become eligible for premium-free Part A, Marketplace financial assistance rules can change. Coordinate the end of Marketplace coverage with the start of Medicare to avoid gaps or repayment issues.
Read New to Medicare and how to enroll. Confirm the rules for your own situation with Medicare, Social Security and the Marketplace before making changes.
