Most Colorado residents looking for health insurance end up choosing between two systems: Health First Colorado (the state's Medicaid program) and the Connect for Health Colorado marketplace. They look similar from the outside — both have free or low-cost coverage, doctor networks, and prescription benefits — but the eligibility rules, networks, and out-of-pocket costs are dramatically different.
This guide is grounded in current CMS and KFF data for Colorado. We update it whenever federal poverty guidelines change (typically January) or when Colorado's Department of Insurance issues new bulletins.

The Short Answer
If your income is above that threshold, you'll qualify for marketplace subsidies on Connect for Health Colorado. The lower your income above 138%, the larger your subsidy.
Health First Colorado: How It Works in Colorado
Health First Colorado is jointly funded by the federal government and the State of Colorado, administered by the state. It's the same federal program you've heard of as "Medicaid," just rebranded with a state-specific name (Colorado's version is called Health First Colorado).
Who qualifies in Colorado:
- Adults aged 19–64 with household income up to 138% FPL (~$20,800 single)
- Pregnant women up to 200%+ FPL
- Children under 19 up to ~250% FPL (often rebranded under CHIP)
- People with disabilities and seniors with limited income/assets
- Parents of dependent children at higher income limits
What it costs: $0 monthly premium for most enrollees. Small copays (often $0–$8) for doctor visits and prescriptions. No deductible. No annual out-of-pocket maximum that you'll realistically hit.
Network: Health First Colorado contracts with managed care organizations (MCOs) like Anthem, Rocky Mountain Health Plans that handle the day-to-day administration. Provider networks are typically robust in major metros (Denver) and thinner in rural counties.
Connect for Health Colorado Marketplace Plans: How They Work
Connect for Health Colorado is Colorado's state-based health insurance marketplace under the Affordable Care Act. You pick a plan from one of 4 private carriers (Anthem, Kaiser Permanente, Cigna, etc.) and the federal government pays a Premium Tax Credit directly to the insurer to lower your monthly bill.
Who qualifies: Anyone who isn't eligible for Medicare, employer coverage, or Health First Colorado can buy a marketplace plan. Subsidies are available based on income — most Colorado families earning between roughly $15,000 and $120,000 will qualify for some level of Premium Tax Credit.
What it costs: After subsidies, monthly premiums in Colorado range from $0 (for very-low-income enrollees) to a few hundred dollars per month. Deductibles range from $0–$1,000 (Platinum/Gold) to $7,500+ (Bronze). The 2026 benchmark Silver plan in Denver runs about $387/month before subsidies.
Network: Each carrier has its own network. Anthem typically offers the broadest network in Colorado; smaller carriers offer narrower networks at lower premiums.

What if my income is right at the edge?
If your projected income falls right at 138% FPL ($20,800 single), apply for Health First Colorado first. The state has 45 days to determine eligibility. If denied, you can immediately enroll in a marketplace plan with full PTC retroactive to the month you applied.
What if my income changes mid-year?
If your income drops, you can switch from a marketplace plan to Health First Colorado mid-year — there's no waiting period. If your income rises above 138% FPL, you'll need to switch from Health First Colorado to a marketplace plan within 60 days of losing Medicaid eligibility.
Can I have both?
No. You're either Medicaid-eligible (and Health First Colorado is your primary coverage) or you're not (and you use the marketplace). The exception: if a family member qualifies for Health First Colorado (often kids, via CHIP) while parents enroll in marketplace plans, that's allowed and common.
