OASIS can help you navigate the Health Insurance Marketplace

The Affordable Care Act (ACA) was passed to improve access to health care in the U.S and make it more affordable through the newly established Health Insurance Marketplace. 

The Marketplace is a website that individuals, families and small business employees can use to shop for insurance plans if they do not have coverage from an employer or  government (under Medicare, Medicaid or the Veterans Administration).

All plans offered through the Marketplace cover essential health benefits such as doctor visits, emergency care, hospitalizations, prescriptions, and more. Plans also cover preventive care – including checkups and screenings – at no cost to the patient.

Through the Marketplace, people will be able to enroll in and purchase plans online, in-person, and over-the-phone. There are trained experts who can answer questions and provide guidance through the enrollment process.

You can enroll at any time during open enrollment, from October 1, 2013 through March 31, 2014.  Coverage can begin as soon as January 1, 2014.

How do I apply for Marketplace coverage?

You can apply for Marketplace coverage in three ways: online, by mail, or in-person with the help of a Navigator or other qualified helper. Visit, the Marketplace website for how and to complete your application. Click here for Marketplace contact information for help 7 days a week, 24 hours a day.

No matter what state you live in, you can use the Marketplace. Some states, however, operate their own Marketplace and in some states the Marketplace is run by the Federal government. You can apply for health coverage, compare all your options, and enroll in a plan in one streamlined application through the Health Insurance Marketplace.

Middle-income people under age 65, who are not eligible for coverage through their employer, Medicaid, or Medicare, can apply for tax credit subsidies available through state-based exchanges.

Get health coverage in 4 steps by going to the Marketplace:  

  1. Set up an account. First, you will provide some basic information, and then you will choose a user name, password, and security questions for added protection.
  2. Apply by filling out the online application. You will provide information about you and your family, such as income, household size and current health coverage. This will help the Marketplace find options that meet your needs. Here's the Marketplace checklist to help you gather what you will need to apply for coverage.
  3. Compare your options and choose a plan. You will be able to see all of the health plan options that you qualify for, including private insurance plans and free and low-cost coverage through Medicaid and the Children’s Health Insurance Program (CHIP). The Marketplace will tell you if you qualify for lower costs on your monthly premiums and out-of-pocket costs on deductibles, copayments, and coinsurance. You will also see details on costs and benefits to help you choose a plan that is right for you.
  4. Enroll. After you choose a plan, you can enroll online and decide how you will pay your premiums to your insurance company. If you, or a member of your family, qualify for Medicaid or CHIP, a representative will contact you to enroll. If you have any questions, there is plenty of live and online help.
