ACA Marketplace plans in Colorado
Looking for ACA marketplace health insurance in Colorado? Here is how this coverage lane works specifically for Colorado residents, what it costs, and how to get it.
Colorado residents buy ACA Marketplace plans through Connect for Health Colorado. These are comprehensive plans that cover the ten essential health benefits, cannot deny you for a pre-existing condition, and are the only plans eligible for income-based premium tax credits.
Because Colorado runs a state-based marketplace, you enroll at Connect for Health Colorado. Plans and prices are set at the county level across Colorado's 64 counties, so two neighbors in different counties can see different options.
Colorado expanded Medicaid, so if your income is low you may qualify for Medicaid instead of a subsidized plan — the Marketplace will tell you when you apply.
Colorado runs a state-based marketplace (Connect for Health Colorado). Residents should enroll through Connect for Health Colorado, and plan menus are set at the county level across 64 counties.
Because Colorado expanded Medicaid, a marketplace application may route lower-income adults to Medicaid instead of a subsidized private plan — that is usually good news for cost.
With an approximate uninsured rate near 7.5% and a population of about 5.9 million, Colorado shoppers should re-check subsidies each year as income and household size change.
