Quick answer: New Hampshire is a bifurcated state. Some disputes are governed by New Hampshire's own specified state law, while others default to the federal No Surprises Act IDR process depending on the plan type and service involved.
New Hampshire's specified state law applies narrowly to out-of-network anesthesiologists, pathologists, radiologists, and emergency physicians, prohibiting balance billing when care was provided at an in-network hospital or ambulatory surgical center. The federal IDR process applies to most other emergency and non-emergency claims, plus air ambulance services.
