Step-by-step in South Dakota
- Read the denial notice. The reason code drives your evidence and the appeal deadline is on the letter.
- File the internal appeal with your insurer within the plan's window (typically 180 days for ERISA/ACA plans; expedited turnaround 72 hours for urgent cases).
- Attach medical necessity evidence that maps to the exact denial reason: guideline citations, chart notes, prior-therapy documentation, peer-reviewed literature.
- Optional: file a complaint with South Dakota Division of Insurance at dlr.sd.gov/insurance/. A DOI complaint runs in parallel — it does not replace the internal appeal.
- Request external review within 4 months of the final internal denial. In South Dakota, external review is administered by South Dakota Division of Insurance. The IRO decision is binding on the insurer.
