Wisconsin Surprise Billing Protections and NSA Compliance


Wisconsin patients are protected from surprise bills by both federal and state law. Understanding these protections helps you respond effectively to unexpected out-of-network charges and dispute them.

Federal No Surprises Act (Effective January 1, 2022)

The federal No Surprises Act, effective January 1, 2022, is the primary surprise billing protection for Wisconsin patients. It requires out-of-network providers and health plans to manage surprise bills in emergency and non-emergency situations.

Wisconsin Act 14 (2022) State Alignment

Wisconsin Act 14, enacted in 2022, aligns with the federal No Surprises Act. The state law reinforces federal protections and ensures state-regulated health plans comply with surprise billing rules.

Emergency Care Coverage

For emergency services at any hospital or emergency facility, patients pay only in-network cost-sharing amounts. Out-of-network providers cannot bill the patient for any amount above the in-network cost-sharing, regardless of the facility's network status.

Scheduled Services at In-Network Facilities

When a patient schedules a non-emergency service at an in-network facility but receives care from an out-of-network provider, the provider must provide 72-hour advance written consent before billing above in-network rates. Without this consent, the patient owes only in-network cost-sharing.

Federal Dispute Resolution and Estimate Requirement

The federal independent dispute resolution (IDR) process handles payment disagreements between providers and health plans. Health plans must also provide Good Faith Estimates before scheduled services so patients know expected costs upfront.

What consent is required for elective OON services in Wisconsin?

For scheduled non-emergency services at in-network facilities, out-of-network providers must provide 72-hour advance written consent before billing above in-network rates. The patient must sign this consent.

How does the federal IDR process work in Wisconsin?

If a provider and health plan disagree on the appropriate payment amount, either party can initiate federal IDR. The independent reviewer determines the appropriate rate and both parties must accept the decision.
