What is the ACA and how does it affect your health insurance?
A Spanish-language explanation of the ACA and what it means for your health coverage.
The Affordable Care Act, also called the ACA or Obamacare, sets health insurance protections and established the Health Insurance Marketplace. Understanding the differences between the law, the Marketplace and your insurance company can make choosing coverage easier.
Who does what?
The ACA is the law. The Marketplace processes applications for coverage and financial assistance. Your insurer administers your plan, provider network and claims. Two people with Marketplace coverage may have different insurers, benefits, premiums and out-of-pocket expenses.
Protection and coverage
Marketplace plans cannot reject you or charge more because of a pre-existing medical condition. They cover essential benefit categories, including hospital care, prescriptions, maternity care and mental health services. Covered does not always mean free: deductibles, copayments, coinsurance and network rules can apply.
Certain preventive services are generally covered without cost sharing when you meet the criteria and use an in-network provider. Tests to investigate symptoms may be billed differently. Ask your provider and insurer how a planned service will be covered.
Financial assistance is a separate decision
Eligible households may receive a premium tax credit. Some also qualify for cost-sharing reductions, which require enrollment in a Silver plan. The Marketplace considers projected household income, household composition and other coverage options. An employer offer may affect assistance even if you turn it down. Being allowed to buy a plan does not automatically mean you qualify for a subsidy.
Prepare a useful comparison
List your doctors, hospitals, medications and preferred pharmacies.
Check the specific plan network and drug formulary.
Compare the premium, deductible, copayments and out-of-pocket limit.
Read the Summary of Benefits and Coverage and keep the exact plan name.
If you see a specialist regularly, compare a year of those visits and prescriptions rather than choosing only by the monthly premium. Also ask what a high-use year could cost. A lower premium may be less useful if your providers or medications are not covered as expected.
