• GetCoveredIllinois Marketplace Plans: These are private health plans offered through the state's official marketplace. They are compliant with the Affordable Care Act (ACA) and are the only place where you can qualify for financial assistance (subsidies) to make coverage more affordable.
• Illinois Medicaid: For individuals and families with lower incomes, Illinois' expanded Medicaid program provides comprehensive health coverage at little to no cost.
• Employer-Sponsored Coverage: If you or a family member works for an employer that offers health benefits, this is typically a cost-effective option.
• Medicare: For individuals aged 65 or older, or those with certain disabilities, Medicare is the federal health insurance program.

Understanding GetCoveredIllinois and Marketplace Subsidies

GetCoveredIllinois is the state-based marketplace where Marion County residents can compare and enroll in ACA-compliant health insurance plans. All plans offered through GetCoveredIllinois cover essential health benefits, including doctor visits, hospital care, prescription drugs, mental health services, and maternity care. Importantly, no one can be denied coverage due to pre-existing conditions.

The primary benefit of enrolling through GetCoveredIllinois is the availability of financial assistance:

• Advance Premium Tax Credits (APTCs): These subsidies reduce your monthly premium payments. Eligibility is based on your household income relative to the Federal Poverty Level (FPL). Under current law, APTCs are available to individuals and families at all income levels above 100% FPL, ensuring that premiums remain an affordable percentage of your income.
• Cost-Sharing Reductions (CSRs): Available to individuals with incomes up to 250% FPL, CSRs help lower your out-of-pocket costs, such as deductibles, copayments, and coinsurance. To receive CSRs, you must enroll in a Silver-tier plan.

When you apply through GetCoveredIllinois, the system will automatically determine your eligibility for these subsidies based on the income information you provide.

Illinois Medicaid and CHIP Eligibility

Illinois has expanded its Medicaid program, known as Illinois Medicaid, making comprehensive health coverage available to many low-income residents of Marion County. Adults with household incomes up to 138% of the Federal Poverty Level (FPL) may qualify for Illinois Medicaid. Unlike states that have not expanded Medicaid, there is no "coverage gap" in Illinois; individuals with incomes between 100% and 138% FPL are eligible for Medicaid, not just marketplace subsidies.

Beyond general adult eligibility, Illinois also offers expansive coverage for pregnant women and children:

• Pregnant Women Medicaid: Illinois Medicaid covers pregnant women with incomes up to an impressive 213% FPL. This coverage includes prenatal care, labor, delivery, and an extended 12 months of postpartum care, a benefit enacted under the American Rescue Plan.
• Children's Health Insurance Program (CHIP): Known as Illinois All Kids, this program provides low-cost health coverage for children with household incomes up to 313% FPL, making it one of the most expansive child coverage programs in the country.

You can apply for Illinois Medicaid or Illinois All Kids through the Application for Benefits Eligibility (ABE) portal at abe.illinois.gov or by calling the Illinois Department of Human Services (DHS) helpline.

Choosing the Right Plan for Your Needs

Selecting a health insurance plan in Marion County involves considering several factors:

• Metal Tiers: Bronze plans have lower premiums but higher out-of-pocket costs. Silver plans offer a balance and are the only plans eligible for Cost-Sharing Reductions. Gold and Platinum plans have higher premiums but lower out-of-pocket costs, covering a larger share of medical expenses.
• Plan Types: Health Maintenance Organizations (HMOs) typically have lower premiums and require you to choose a primary care provider (PCP) and get referrals for specialists. Exclusive Provider Organizations (EPOs) also use a network but may not require a PCP or referrals, though out-of-network care is generally not covered. Preferred Provider Organizations (PPOs) offer the most flexibility, allowing you to see out-of-network providers for a higher cost and generally not requiring referrals. In Illinois, PPO plans are available on-exchange through GetCoveredIllinois.
• Provider Networks: Ensure that your preferred doctors, specialists, and the local hospital, SSM Health St. Mary's Hospital – Centralia, are included in the plan's network.
• Prescription Drug Coverage: Check the plan's formulary to ensure your necessary medications are covered and understand their cost-sharing structure.
