Published reversal rate

Notes

Mississippi historically classified as relying on HHS-administered federal process. Note KFF 2024 state list only flags 5 states (AL/FL/GA/TX/WI); MS may have shifted classification. Flag for re-verification.

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.
