ACA Plan Types and Financial Help for Thornton Residents

Connect for Health Colorado offers a variety of plan types under the Affordable Care Act (ACA), categorized into metal tiers: Bronze, Silver, Gold, and Platinum. These tiers indicate the percentage of healthcare costs the plan is expected to cover, with Bronze plans having lower premiums and higher out-of-pocket costs, and Gold/Platinum plans offering higher premiums but lower costs when you receive care. Importantly, PPO plans ARE available on-exchange in Colorado, alongside HMO and EPO options, giving Thornton residents flexibility in choosing their preferred provider network.

Many Thornton residents qualify for financial assistance to help pay for their health insurance premiums and out-of-pocket costs. Advance Premium Tax Credits (APTCs) can reduce your monthly premium, and Cost-Sharing Reductions (CSRs) can lower deductibles, copayments, and coinsurance, particularly for those who enroll in Silver-tier plans and meet specific income criteria. These subsidies are crucial for making coverage affordable, especially for individuals and families with moderate incomes.

For those with lower incomes, Colorado has expanded its Medicaid program, known as Health First Colorado. Adults in Thornton with household incomes up to 138% of the Federal Poverty Level (FPL) qualify for comprehensive health coverage at little to no cost. This expansion, enacted in 2014, ensures that individuals and families who earn between 100% and 138% FPL are eligible for Medicaid, rather than falling into a coverage gap. Additionally, pregnant women with incomes up to 195% FPL and children in households up to 260% FPL can receive coverage through Child Health Plan Plus (CHP+), applied for via Colorado PEAK (colorado.gov/PEAK).
