Neither Humana nor Cigna sells 2026 ACA marketplace plans in Illinois; the insurers that do are Ambetter, Blue Cross and Blue Shield of Illinois, MercyCare, Molina Healthcare, Oscar and UnitedHealthcare. The right choice depends on your income, which doctors and hospitals you need in-network, and your prescription medications — not which carrier has the better logo.

Humana vs Cigna in Illinois
In Illinois, marketplace plans are sold through Get Covered Illinois, and neither carrier is on it for 2026. Plan availability, networks, and premiums vary significantly by county and ZIP code across Illinois — what is available in Chicago, Springfield, and Rockford is not necessarily available in smaller or rural parts of the state.
The most important thing to understand about comparing any two marketplace carriers: premium is not the same as cost. A plan with a lower monthly premium may have a higher deductible, narrower network, or worse formulary coverage for your medications — resulting in higher total annual spending than a plan that cost more per month.

How to Choose Between the Two
Neither carrier sells 2026 marketplace plans in Illinois, so compare the insurers that do: Ambetter, Blue Cross and Blue Shield of Illinois, MercyCare, Molina Healthcare, Oscar and UnitedHealthcare. Compare their after-subsidy premiums, network coverage for your specific doctors, and formulary coverage for your prescriptions before deciding.
If you qualify for ACA subsidies: Compare after-subsidy costs: the cheaper-looking plan before subsidies may not be cheapest after your premium tax credit is applied.
If you are paying full unsubsidized cost: At full unsubsidized cost, total annual cost (premium + expected out-of-pocket) determines value. Consider deductible, OOP max, and network breadth.
What to Check Before You Choose
Before selecting either plan, do these four checks using each carrier’s provider directory and formulary tool:
- Doctor check: Search for your primary care physician and any specialists you see regularly in each carrier’s Illinois provider directory. Networks can be narrow, and a doctor who is in-network with one carrier may not be with the other.
- Hospital check: Confirm the hospital you would go to for a planned procedure or emergency is in-network. Hospital network participation differs from physician network participation.
- Drug formulary check: Look up every prescription you take in the formulary for each plan you are considering. Note the tier and the cost-sharing for each. Small formulary differences can result in hundreds of dollars in annual cost difference.
- After-subsidy premium: If you qualify for a premium tax credit, enter your income and household size at Get Covered Illinois to see the after-subsidy premium for each plan. The after-subsidy number is what you actually pay.
This state has expanded Medicaid. Buyers with income below approximately $21,600/year (single adult) may qualify for free Medicaid coverage instead of a marketplace plan.
