Best Health Insurance Plans in Colorado (2026)
Top-rated ACA Marketplace plans in Colorado ranked by CMS quality scores and premium data. Plans are displayed based on federal marketplace data — not broker recommendations or paid placements.
Rankings are based on CMS star ratings (clinical quality, member experience, plan efficiency) and premium data from the federal marketplace. Policymage is not a licensed insurance broker — we display data, not recommendations. Prices reflect a 30-year-old near Denver, CO before subsidies.
Plan rankings for Colorado come from Connect for Health Colorado
Colorado runs its own state-based exchange, Connect for Health Colorado, instead of HealthCare.gov. Quality-rated plan data for Colorado isn't available through the federal CMS API that Policymage uses for federal marketplace states. To browse and compare top-rated plans with subsidy estimates, visit Connect for Health Colorado directly. You can still use our guides to understand metal tiers, quality ratings, and subsidy eligibility before enrolling.
How to Choose the Best Plan in Colorado
1Consider your healthcare usage
If you rarely see doctors, a Bronze plan with lower premiums may save you money. If you have chronic conditions or take regular prescriptions, a Gold or Silver plan with lower cost-sharing may be cheaper overall.
2Check if your doctors are in-network
HMO plans require you to use in-network providers and get referrals for specialists. PPO plans offer more flexibility. Verify your preferred doctors and hospitals accept your plan before enrolling.
3Estimate your total annual cost
Look beyond the monthly premium. Add up the premium × 12, plus your expected deductible and copay costs. A lower-premium Bronze plan can cost more total if you need regular care.
4Check subsidy eligibility
If your household income is between 100%–400% of the Federal Poverty Level, you likely qualify for APTC to reduce your premium. Some Colorado residents qualify for $0/month Silver plans. Enter your income in the compare tool to see your options.
Affordable, budget, and low-cost ACA plans in Colorado
Whether you're searching for cheap, affordable, budget-friendly, low-cost, inexpensive, economical, or discount health insurance in Colorado, every ACA Marketplace plan available through Connect for Health Colorado must cover the same 10 Essential Health Benefits set by federal law — preventive care, emergency services, hospitalization, prescription drugs, maternity, mental health, and more. No Marketplace plan can deny you for a pre-existing condition or charge you more for being sick. The only real differences between a "cheap" plan and an expensive one are the monthly premium, the metal tier, the provider network, and how much you pay out of pocket when you actually use care. Below we break down every way to find lower-cost coverage in Colorado so you can match a plan to both your budget and your expected medical needs.
Budget Marketplace coverage in Colorado
Bronze-tier plans have the lowest monthly premium of any metal level in Colorado, making them the budget choice for healthy adults who rarely visit the doctor. Expect a high deductible (often $7,500+) in exchange for the low monthly cost. If you qualify for the Premium Tax Credit (APTC), your effective premium can drop significantly — many Colorado residents pay $0–$50/month for Bronze coverage after subsidies are applied.
Low-cost Silver plans & Cost-Sharing Reductions
Silver-tier plans are the only tier eligible for Cost-Sharing Reductions (CSR), which lower your deductible, copays, and out-of-pocket maximum if your household income is between 100% and 250% of the Federal Poverty Level. For Colorado residents in that income range, an enhanced Silver plan often beats a Bronze plan on total annual cost — the slightly higher premium is more than offset by far lower costs when you receive care.
Discount HSA-eligible HDHP options
HSA-eligible High-Deductible Health Plans (HDHPs) in Colorado let you contribute pre-tax dollars to a Health Savings Account. For 2025 IRS limits, individuals can contribute up to $4,300 and families up to $8,550. Unused funds roll over year to year — and after age 65, you can withdraw for any expense without penalty. An HDHP pairs a low, economical premium with a tax-advantaged savings vehicle.
Cheap catastrophic plans (under 30 only)
Colorado residents under 30 — or those with a hardship/affordability exemption — may qualify for catastrophic coverage. Premiums are the lowest of any tier, but the deductible equals the federal out-of-pocket maximum (~$9,200 in 2025) so it's true emergency-only coverage. Catastrophic plans don't qualify for APTC subsidies.
Inexpensive HMO vs. PPO networks in Colorado
Network type is one of the biggest levers on price in Colorado. HMO and EPO plans restrict you to an in-network provider list but carry noticeably lower premiums, making them the most inexpensive structure for most residents. PPO plans cost more but let you see out-of-network providers. If your preferred doctors are in an HMO network, it's usually the most value-efficient choice.
Finding the best value (lowest total cost) in Colorado
The cheapest premium isn't always the most affordable plan overall. The smart way to shop in Colorado is to estimate your total annual cost — premium × 12, plus your expected deductible and copays — rather than chasing the lowest sticker price. A modest mid-tier plan can be the best value if you take regular prescriptions or see specialists. Enter your ZIP, age, and income in our compare tool to rank plans by real total cost after subsidies, not just headline premium.
Health insurance companies in Colorado
These are the major health insurers that have offered ACA Marketplace plans to Colorado residents in recent plan years. Carrier participation and the counties each insurer serves change every year, so always confirm current availability for your ZIP code on Connect for Health Colorado before enrolling. Every plan from every carrier below covers the same federally-required Essential Health Benefits — they differ on premium, provider network, and which doctors and hospitals are in-network.
Before choosing an insurer in Colorado, look up each plan's provider directory on Connect for Health Colorado and confirm your doctors, preferred hospitals, and prescription drugs are covered in-network. Network fit usually matters more than a small premium difference.

Medicaid eligibility in Colorado
Colorado has expanded Medicaid under the ACA. If your household income is at or below 138% of the Federal Poverty Level (about $20,783/year for an individual, $43,056/year for a family of 4), you likely qualify for free or very low-cost Medicaid instead of a Marketplace plan.
Medicaid in Colorado covers doctor visits, hospital care, prescription drugs, preventive screenings, mental health care, and more. There's no Open Enrollment window — you can apply year-round. Apply directly through your state Medicaid office or Colorado's marketplace, which will check your eligibility automatically.
APTC subsidy examples for Colorado households
The Advance Premium Tax Credit (APTC) caps what Colorado residents pay for the benchmark Silver plan as a percentage of household income. Through the Inflation Reduction Act extension, the 400% Federal Poverty Level (FPL) cliff is suspended through 2025 — households above 400% FPL still qualify for APTC if benchmark Silver exceeds 8.5% of income.
| Household size | Annual income | % of FPL | Capped premium share |
|---|---|---|---|
| 1 person | $22,590 | 150% | ~4% of income |
| 1 person | $37,650 | 250% | ~6% of income |
| 2 persons | $40,880 | 200% | ~4% of income |
| 4 persons | $78,000 | 250% | ~6% of income |
| 4 persons | $124,800 | 400% | ~8.5% of income |
Federal Poverty Level figures use the 2025 HHS guidelines for the 48 contiguous states & DC. Alaska and Hawaii use higher FPL thresholds. Actual subsidy depends on your county's benchmark Silver premium, household composition, and tax filing status. Always verify with official Marketplace before enrolling.

Frequently asked questions about ACA insurance in Colorado
When does Open Enrollment end in Colorado for ACA plans?
Open Enrollment for Colorado residents runs from November 1 through January 15. Colorado runs its own exchange (Connect for Health Colorado), which set the January 15 deadline. Outside Open Enrollment, you need a Qualifying Life Event to enroll in a Special Enrollment Period.
How much does ACA health insurance cost in Colorado?
Premiums in Colorado vary by age, county, plan tier, and tobacco use. Bronze plans offer the lowest premiums; Platinum plans have the highest. APTC subsidies can significantly reduce your effective cost based on household income.
Does Colorado use HealthCare.gov or its own state exchange?
Colorado runs its own state-based Marketplace called Connect for Health Colorado (https://connectforhealthco.com). You enroll there directly — not at HealthCare.gov. Plan offerings, enrollment dates, and customer support are managed by Colorado, not the federal government.
Has Colorado expanded Medicaid under the ACA?
Yes. Colorado has expanded Medicaid, so adults with household income up to 138% of the Federal Poverty Level (approximately $20,783/year for an individual) qualify for free or very low-cost Medicaid. There's no Open Enrollment window — you can apply year-round.
What are the income limits for ACA subsidies in Colorado?
Premium Tax Credit eligibility starts at 100% of the Federal Poverty Level — about $15,060/year for an individual or $31,200/year for a family of 4. Through 2025, the upper income cap is removed: Colorado residents above 400% FPL still qualify if benchmark Silver costs more than 8.5% of their income. Use the Connect for Health Colorado subsidy calculator for your exact estimate.
What are the metal tiers in Colorado (Bronze, Silver, Gold, Platinum)?
Colorado ACA plans come in four metal tiers based on actuarial value (the percentage of medical costs the plan covers on average): Bronze (~60%), Silver (~70%), Gold (~80%), and Platinum (~90%). Bronze has the lowest premium and highest deductible; Platinum has the highest premium and lowest deductible. Silver is the "benchmark" tier used to calculate APTC subsidies, and it's the only tier eligible for Cost-Sharing Reductions if you qualify by income.
Are HSA-eligible plans available in Colorado?
Yes. HSA-eligible High-Deductible Health Plans (HDHPs) are available in Colorado through Connect for Health Colorado. For 2025, HDHPs must have a deductible of at least $1,650 (individual) or $3,300 (family), and you can contribute up to $4,300 (individual) or $8,550 (family) to your HSA pre-tax. HSA contributions roll over year-to-year and can be invested.
Do Colorado ACA plans cover dental and vision?
Colorado ACA Marketplace plans for adults include preventive care, mental health, prescriptions, hospitalization, and the 10 Essential Health Benefits — but adult dental and vision are not federally required. Most Colorado plans cover pediatric dental and vision automatically. For adult dental/vision, you typically buy a separate standalone plan through Connect for Health Colorado or directly from an insurer.
What is a Qualifying Life Event for Special Enrollment in Colorado?
Outside Open Enrollment, Colorado residents can enroll in or change ACA plans within 60 days of a Qualifying Life Event: loss of other health coverage, marriage or divorce, birth or adoption of a child, moving to a new county or state, a change in income that affects subsidy eligibility, becoming a US citizen, or release from incarceration. Have documentation ready when applying through Connect for Health Colorado.
How do I find in-network doctors and hospitals in Colorado?
Each Colorado ACA plan has its own provider network. Before enrolling, look up the plan on Connect for Health Colorado, click the carrier name to access their provider directory, and search for your specific doctors and preferred hospitals by name. Out-of-network care typically isn't covered (HMO plans) or costs significantly more (PPO plans). If you have an existing provider relationship, network match is usually more important than the lowest premium.
