New to helping someone in South Dakota?
You do not need a law degree to help someone fight a health insurance denial. Start by gathering three basic documents:
- Insurance card — shows which company administers the plan (Avera, Sanford, Wellmark, and others).
- Denial letter or explanation of benefits (EOB) — the notice that says a service was denied, not paid, or needs approval first. Look for appeal instructions and a deadline.
- Summary of Benefits and Coverage (SBC) — helps you tell whether the fight is about medical necessity or whether the benefit exists at all.
Your first tasks: identify what type of plan this is (HealthCare.gov, job-based, South Dakota Medicaid, Medicare) and write down the appeal deadline from the letter.
For many South Dakota-regulated plans, you have an internal grievance with the carrier first, then a right to external review filed with the Division of Insurance under ARSD 20:06:53 (implementing SDCL 58-17I and related statutes).
For steps that work in every state, read these general guides first, then return here for South Dakota rules:
What is different in South Dakota?
- HealthCare.gov: South Dakota uses the federal Marketplace. For 2026, certified exchange carriers include Avera Health Plans, Sanford Health Plan, and Wellmark BCBS of South Dakota (Wellmark in select counties). Plan info: DLR — 2026 exchange plans.
- Prior authorization: SDCL 58-17H utilization review; step-therapy overrides (SB 155)—5 days standard / 72 hours urgent with deemed approval if deadlines missed; no statewide gold card law (HB 1199 adds annual PA reporting and review starting 2026).
- Internal appeals: SDCL 58-17I grievance process; federal 180-day filing on many ACA plans; deemed exhaustion after 30 days without a written grievance decision.
- External review: File with Division of Insurance within 4 months; DFR assigns IRO; 45 days standard decision; call 605-773-3563 for expedited instructions; binding on carrier; free to you.
- South Dakota Medicaid: Fair hearing through DSS Office of Administrative Hearings—deadline on your notice—not commercial IRO review.
