Maine Surprise Billing Protections and NSA Compliance


Maine patients are protected from surprise billing through the federal No Surprises Act. Patients pay only in-network cost-sharing for covered emergency and scheduled services, preventing unexpected out-of-network bills.

Federal No Surprises Act (January 1, 2022)

The federal No Surprises Act applies to all ERISA and state-regulated health plans in Maine. It prohibits balance billing for emergency services and scheduled non-emergency services at in-network facilities. Out-of-network providers are limited to collecting in-network cost-sharing only.

Maine Surprise Billing Framework

Maine has a state surprise billing law (24-A MRSA ยง4303) that works alongside the federal No Surprises Act, protecting patients from out-of-network charges for emergency and scheduled facility-based services.

Emergency Care In-Network Cost-Sharing Only

For emergency services at any hospital or emergency facility in Maine, patients pay only in-network cost-sharing. Out-of-network providers cannot balance bill the patient for amounts exceeding in-network cost-sharing, regardless of network status. This protection extends to post-stabilization care until the patient can be safely transferred.

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 advance written consent before billing above in-network rates. Without proper consent meeting federal standards, the patient owes only in-network cost-sharing.

Good Faith Estimate and Cost Transparency

Health plans in Maine must provide Good Faith Estimates before scheduled services. Providers must supply cost estimates on request to help patients understand expected out-of-pocket costs. Uninsured and self-pay patients can dispute charges that exceed the Good Faith Estimate by $400 or more.

Federal Independent Dispute Resolution (IDR) Process

Maine uses the federal IDR process for payment disputes between providers and health plans. Either party can initiate IDR if they disagree on appropriate payment, and an independent reviewer determines the rate based on the qualifying payment amount, provider training, case complexity, and applicable federal benchmarks.

How to Invoke Surprise Billing Protections in Maine

  1. Identify the unexpected OON charge on the Explanation of Benefits (EOB).
  2. Notify the health plan citing the federal No Surprises Act in writing.
  3. Request an in-network rate adjustment with supporting documentation.
  4. File a complaint with the Maine Bureau of Insurance if unresolved within 30 days.
