They are only available with Silver-tier plans and are typically for individuals and families earning up to 250% FPL. For those with lower incomes, Colorado offers Health First Colorado, the state's Medicaid program. Colorado expanded Medicaid in 2014, meaning adults with household incomes up to 138% FPL may qualify for comprehensive health coverage at little to no cost. For example, a single individual with an income up to approximately $20,782 (based on 2024 FPL guidelines) may be eligible. Colorado's Child Health Plan Plus (CHP+) also covers pregnant women with incomes up to 195% FPL and children in households up to 260% FPL, providing vital maternity and pediatric care.

Making Your Health Insurance Decision in Castle Rock

Choosing the right health insurance plan requires evaluating your healthcare needs, budget, and eligibility for financial assistance. Here’s a guide to help you make an informed decision:
Your Income Level (FPL) Recommended Action Key Benefit
Below 138% FPL Apply for Health First Colorado (Medicaid) Comprehensive coverage at little to no cost.
100% - 250% FPL Consider Silver plans with Cost-Sharing Reductions Lower deductibles, copays, and out-of-pocket maximums.
100% - 400% FPL Apply for Advance Premium Tax Credits on any metal tier Reduced monthly premiums on marketplace plans.
Above 400% FPL Shop for plans on Connect for Health Colorado or off-marketplace Access to a wide range of plans, though without federal subsidies.
Consider your expected medical needs for the upcoming year. If you anticipate frequent doctor visits or require specific medications, a plan with lower out-of-pocket costs (like a Gold or Silver plan with CSRs) might be more cost-effective in the long run, even with a slightly higher premium. If you are generally healthy and primarily want coverage for emergencies, a Bronze or Catastrophic plan (if eligible) with a lower premium but higher deductible could be suitable. Remember that a licensed health insurance agent can provide personalized guidance, help you compare plans, and assist with the enrollment process through Connect for Health Colorado, all at no cost to you.
