South Dakota has one of the smallest and least competitive ACA marketplaces in the country, with only 10–20 plans available statewide. Sanford Health Plan and Wellmark BCBS are the primary carriers. Silver premiums average $490–$515/month for a 40-year-old before subsidies, reflecting the state's small risk pool and rural geography. South Dakota uses Healthcare.gov for marketplace enrollment. Most of the state's population is concentrated in Sioux Falls and Rapid City, while the vast remainder is frontier or reservation land with very limited provider infrastructure.
South Dakota voters approved Medicaid expansion by ballot initiative in November 2022 (Amendment D), and expansion took effect July 1, 2023 — one of the most recent expansions nationally. The Republican legislature had blocked expansion for years. The expansion is expected to cover approximately 40,000–50,000 Dakotans. South Dakota's large Lakota Sioux population on reservations benefits from IHS coverage, but Medicaid expansion provides critical coverage for non-IHS-eligible low-income adults. The state has no state-based exchange or reinsurance program.
