- Review date
Illinois is a bifurcated state. State payment and dispute rules may apply to specified out-of-network services covered by Illinois-regulated plans.
Plan and jurisdiction considerations
Validate plan regulation and the service/facility/provider facts. Federal IDR remains important for self-funded ERISA plans and state-law gaps.
Federal fallback
Use Federal IDR where Illinois law does not determine the out-of-network rate and federal eligibility is established.
Timing and fees
Illinois dispute prerequisites and filing details are separate from federal timeframes. Confirm current Department guidance, required negotiation, and fee allocation.
Air ambulance considerations
Federally protected air ambulance services generally use Federal IDR.
