Working with an assister can help you determine which plan will be best for you.

It is important that you explore your options to make sure you get the coverage you need.

The good news is that Maine has expanded MaineCare. Within a certain income bracket you may become eligible for a free health plan through MaineCare. If the Marketplace screens you as eligible for MaineCare, it will send your application to Maine DHHS for a final eligibility determination. Your Maine Enrollment Assister can help you with any questions you may have about MaineCare.

6. How do I prove my eligibility for the subsidy? You’ll need to provide detailed information on the application, including:

  • Social Security number for all people applying for coverage
  • Birth dates and home addresses for all people applying for coverage under the plan
  • Name of employer and income information for every member of your 
    household, even if they aren’t all applying for coverage
  • Estimated household income

7. What are the different types of plans? Marketplace plans fall into four categories:

Bronze – Lowest monthly premium, highest out-of-pocket cost, very high deductibles. 

Silver – The most popular plan. Moderate premiums, moderate out-of-pocket costs, deductibles are lower than Bronze plan.

Gold – High monthly premiums, lower out-of-pocket costs, low deductibles.

Platinum - The highest monthly premiums, lowest out-of-pocket costs, and deductibles. 

There is also a catastrophic plan, which includes all the benefits required by the ACA, including free preventive care. These plans carry low monthly premiums and very high deductibles. But they are only available to individuals under the age of 30 and to those who get an exemption from the Marketplace because, for example, they cannot afford coverage any other way.

A Maine Enrollment Assister can help you with any questions you may have. If you don’t do anything by Dec. 15, 2021 you will most likely be automatically renewed in your current plan. If your plan is no longer available, the Marketplace will enroll you in the most similar plan, unless you are eligible for Medicare. If you are eligible for Medicare, the Marketplace will not enroll you into a new plan.

9. Does it pay to shop around for a plan? Yes, because there have been many changes in the 2022 plans and there are many new plans available this year. You should be sure to check if the plan you are considering covers your doctors, prescription drugs and hospitals you are likely to use. Premiums also vary from year to year. 

IMPORTANT: Your premium must be paid before January 1, 2022 for coverage to start on January 1, 2022. If you don’t pay on time, your plan might be canceled and you may have to wait until the next open enrollment period to sign up for another plan.
