Balance Billing Laws in Wisconsin
Your medical billing rights and protections in Wisconsin.
Wisconsin does not have a comprehensive state balance billing law. Residents rely on the federal No Surprises Act, effective January 1, 2022, for protection against unexpected bills for out-of-network emergency and certain non-emergency care at in-network facilities.
Key Protections in Wisconsin
Emergency services: Federal NSA limits cost-sharing for out-of-network emergency services to in-network amounts
Out-of-network at in-network facility: Surprise billing prohibited without advance written consent for non-emergency care
Good faith estimate: Providers must give advance cost estimates to uninsured and self-pay patients
Filing Information
Within 1 year of receiving the bill for federal NSA disputes
Additional Notes
Wisconsin consumers rely primarily on federal No Surprises Act protections. The Office of the Commissioner of Insurance can provide guidance and assistance.
