Both Blue Cross Blue Shield and Aetna sell ACA-compliant health insurance plans in South Dakota. 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.

Blue Cross Blue Shield vs Aetna in South Dakota
Both carriers offer ACA marketplace plans in South Dakota through the federal marketplace (healthcare.gov). Plan availability, networks, and premiums vary significantly by county and ZIP code across South Dakota — what is available in Sioux Falls and Rapid City 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.

Two Established Carriers: Network vs. CVS Access
BCBS and Aetna are both established carriers. BCBS typically has the broader provider network and more years in the state market. Aetna's CVS Health integration offers distinctive pharmacy and MinuteClinic benefits.
If you qualify for ACA subsidies: Compare after-subsidy premiums; BCBS's broader network sometimes carries a premium worth the cost at subsidized rates.
If you are paying full unsubsidized cost: At full cost, compare networks for your specific providers. BCBS's depth often justifies the premium for buyers with established specialist relationships.
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 South Dakota 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 (~$15,650/year for one adult) may fall into the coverage gap with no affordable option unless they qualify for CHIP or other programs.
