Frequently asked questions
How do I request external review in Mississippi?
After your internal appeal is exhausted, file the external review request with Mississippi's designated IRO process. Federal floor: 4 months from final internal denial. Mississippi-specific instructions are in your denial notice, on the state insurance department website (https://www.mid.ms.gov/), or via the Consumer Assistance Program. Self-funded ERISA plans use the federal IRO process; fully-insured commercial plans use the state IRO process.
Is the IRO decision binding?
Yes — if the IRO overturns the plan's denial, the plan MUST cover the service. ACA §2719 makes external review decisions binding on the plan.
Can I file expedited external review?
Yes, for urgent cases where standard timelines would jeopardise life, health, or function. Expedited decisions: 72 hours.
Does external review cost anything?
Most state IRO processes are FREE to consumers. Plans pay the IRO fee.
