Neither Oscar Health nor Aetna sells 2026 ACA marketplace plans in Wisconsin; the insurers that do are Anthem Blue Cross and Blue Shield, Aspirus Health Plan, CareSource (Common Ground Healthcare), Dean Health Plan, Group Health Cooperative-SCW, HealthPartners, Medica, MercyCare Health Plans, Network Health, Quartz, Security Health Plan 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.

Oscar Health vs Aetna in Wisconsin
In Wisconsin, marketplace plans are sold through HealthCare.gov, and neither carrier is on it for 2026. Plan availability, networks, and premiums vary significantly by county and ZIP code across Wisconsin — what is available in Milwaukee and Madison 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.

About Aetna in Wisconsin
Aetna is backed by CVS Health, which also operates prescription benefit management (Caremark) and retail pharmacy. Aetna (CVS Health) left the ACA individual marketplace in every state at the end of 2025, so there is no Aetna marketplace plan to buy in Wisconsin for 2026. Aetna still sells employer group coverage. Aetna's CVS Health integration gives members access to MinuteClinic locations for routine care.
Prescriptions: Aetna plans often feature preferred pricing for CVS pharmacy locations. Check if your prescriptions are on the Aetna formulary at an acceptable tier.

How to Choose Between the Two
Neither carrier sells 2026 marketplace plans in Wisconsin, so compare the insurers that do: Anthem Blue Cross and Blue Shield, Aspirus Health Plan, CareSource (Common Ground Healthcare), Dean Health Plan, Group Health Cooperative-SCW, HealthPartners, Medica, MercyCare Health Plans, Network Health, Quartz, Security Health Plan 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 Wisconsin 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 the federal marketplace (healthcare.gov) to see the after-subsidy premium for each plan. The after-subsidy number is what you actually pay.
Wisconsin hasn’t adopted the ACA’s Medicaid expansion, but BadgerCare Plus covers adults with income up to the federal poverty level (~$15,650/year for one adult), so there is no coverage gap; above that level, marketplace subsidies apply.
