Small Business Health Insurance in South Dakota: What You Need to Know
South Dakota has one of the most distinctive small group insurance markets in the country. The two dominant carriers — Sanford Health Plan and Avera Health Plans — are both affiliated with South Dakota's major hospital systems. Sanford Health is the nation's largest rural health system, headquartered in Sioux Falls; Avera Health is the other dominant system, with a strong presence in the eastern part of the state. Choosing an insurer in South Dakota is often inseparable from choosing a hospital system.
South Dakota voters approved Medicaid expansion in 2022, with the program launching July 2023. Adults earning up to 138% FPL now qualify for SD Medicaid.
Who Qualifies as a Small Employer in South Dakota
South Dakota follows the ACA definition: 1–50 full-time equivalent employees. Full-time is 30 or more hours per week. South Dakota's July 2023 Medicaid expansion means some lower-wage workers now have Medicaid available. In agriculture and food processing — South Dakota's largest industries — this affects group plan participation calculations. Businesses with fewer than 50 FTEs are not required to offer coverage.
Coverage Options for South Dakota Small Businesses
ACA Small Group Plans
All South Dakota small group plans are guaranteed issue, community-rated, and must include ACA essential health benefits. The South Dakota Division of Insurance regulates carrier conduct and plan designs.
Federal SHOP Marketplace
South Dakota employers access the SHOP at healthcare.gov/small-businesses. Purchasing through SHOP is required to claim the Small Business Health Care Tax Credit.
QSEHRA Alternative
South Dakota employers with fewer than 50 employees can use a QSEHRA. 2026 limits: $6,350 (self-only) and $12,800 (family). The individual market in South Dakota is thin, particularly in rural areas. Confirm individual market plan availability in your specific county before choosing QSEHRA over a group plan.
Carriers Offering Small Group Plans in South Dakota
- Sanford Health Plan — Affiliated with Sanford Health, headquartered in Sioux Falls. Sanford is the nation's largest rural health system, with hospitals and clinics across South Dakota, North Dakota, Minnesota, and Iowa. The Sanford plan's most obvious advantage is seamless access to the affiliated Sanford network. A strong default choice for employers in Sioux Falls and communities where Sanford is the primary provider.
- Avera Health Plans — Affiliated with Avera Health, with a strong presence in eastern and central South Dakota. Avera hospitals and clinics are the primary provider in many SD communities. For employers in Aberdeen, Yankton, and areas where Avera is the dominant health system, Avera Health Plans often delivers the best network access and integration.
- Wellmark Blue Cross Blue Shield — Wellmark is the BCBS affiliate serving South Dakota and Iowa. Offers a broad network and the ability to access providers across both Sanford and Avera networks in many cases. The best option for employers whose employees use a mix of providers, or for businesses that want a carrier independent of the major health system affiliates.
The Sanford vs. Avera Dynamic
In much of South Dakota, the hospital and clinic your employees use is often determined by geography — Sanford dominates in some areas, Avera in others. Before selecting a carrier, it's worth asking your employees: where do they get their primary care? Which hospital is closest to them? If most employees use Sanford facilities, Sanford Health Plan likely offers the best in-network access. If Avera is primary, Avera Health Plans makes more sense. If your team is mixed, Wellmark's broader network may be the most practical choice.

Frequently Asked Questions
What makes South Dakota's insurance market different from other states?
The two largest carriers are both affiliated with the state's major hospital systems. Choosing Sanford Health Plan vs. Avera Health Plans is often a proxy for choosing which hospital network your employees access. Wellmark BCBS offers a more provider-agnostic option. Where your employees get their care should drive carrier selection in South Dakota.
Has South Dakota expanded Medicaid?
Yes, as of July 2023. Voters approved it in November 2022. Adults up to 138% FPL now qualify for SD Medicaid. If you have lower-wage employees and haven't revisited your group plan participation since then, some may now be Medicaid-eligible.
Does South Dakota have its own SHOP marketplace?
No. South Dakota uses the federal SHOP at healthcare.gov/small-businesses.
What if my employees are split between Sanford and Avera service areas?
Wellmark BCBS is typically the most practical choice in that situation, as it generally has broader cross-network access than either health-system-affiliated carrier. A broker can verify network coverage for both the Sanford and Avera areas where your employees live and work.
How does South Dakota's rural geography affect group coverage?
Telemedicine is an important plan component for employees in rural South Dakota. Both Sanford and Avera have invested heavily in telemedicine services given the state's geographic spread. Confirm that any plan you consider includes robust telemedicine access, particularly if your employees are scattered across the state.
