Maine No Surprises Act & IDR Rules

Last verified: July 2026 · For informational purposes only, not legal advice

Quick answer: Maine is a bifurcated state. Some disputes are governed by Maine's own specified state law, while others default to the federal No Surprises Act IDR process depending on the plan type and service involved.

How it works

Maine's specified state law applies to emergency items and services and non-emergency items and services furnished by out-of-network providers at in-network facilities. The federal IDR process applies mainly to air ambulance services. Maine is also one of six states that allows self-funded ERISA plans to voluntarily opt into the state process.
