State-run. Request it through the regulator after the plan's final internal denial; the federal floor is 4 months (45 CFR 147.136).

Published reversal rate

0.43% of reviews reversed the plan (2024) · source

Notes

~43% of cases reversed in 2024 per NBC News attribution to SCDOI. SC DOI does not publish dedicated annual external-review report online; flag as secondary citation.

Before external review

File the plan's internal appeal first (at least 180 days for ACA-compliant plans; the letter states the date). Ask for the claim file and the criteria the plan applied; both are free on request. Self-funded employer plans use the federal external review and the U.S. Department of Labor, not the state.
