Both UnitedHealthcare and Cigna sell 2026 ACA marketplace plans in Mississippi. 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.

Looking for Cigna Global? That is Cigna’s international health insurance for people living or working abroad. It isn’t sold on HealthCare.gov and isn’t an ACA marketplace plan; this page is about Cigna’s U.S. plans.
Before you pick Cigna: it is leaving the marketplace for 2027. On 30 April 2026 Cigna announced it is ending individual ACA coverage in all 11 states where it sells them, Mississippi included — about 369,000 people nationally.
A Cigna plan bought for 2026 runs through 31 December 2026 and does not renew. You would choose a different insurer during Open Enrollment for 2027 (1 November 2026 – 15 January 2027), and if you leave it to the marketplace, it can move you to a plan whose network is not the same.

UnitedHealthcare vs Cigna in Mississippi
In Mississippi, marketplace plans are sold through HealthCare.gov, and both carriers file plans there for 2026. Neither carrier sells a PPO here — all 2,834 plans filed in Mississippi are EPO or HMO. Plan availability, networks, and premiums vary significantly by county and ZIP code across Mississippi — what is available in Benton County is not necessarily available in Yazoo County, and neither list is 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 Cigna in Mississippi
Cigna is primarily known for employer group plans; their marketplace ACA presence is a complement to their larger commercial business. In Mississippi, where Cigna Healthcare files in 41 of the 82 counties, Cigna competes in the ACA marketplace alongside UnitedHealthcare and other carriers. Cigna's ACA marketplace footprint is more limited than their employer-market presence. Verify availability in your specific county before comparing. Cigna is also leaving the individual ACA market for 2027, so a 2026 plan here is a one-year plan.
Prescriptions: Cigna uses Express Scripts (subsidiary) for pharmacy benefits management. Check your specific drugs on their formulary.
Best for: Cigna in Mississippi is generally best suited for buyers who value robust behavioral health and mental health coverage, or who travel internationally.
How to Choose Between the Two
Both carriers compete in the ACA marketplace. 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.
Buying for a business, not just yourself?

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 Mississippi 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.
This state has NOT expanded Medicaid. Buyers below the federal poverty level (~$15,960/year for one adult) may fall into the coverage gap with no affordable option unless they qualify for CHIP or other programs.
