Montana Balance Billing Protections and Patient Rights


Montana patients are protected from balance billing under the federal No Surprises Act for emergency services and scheduled services at in-network facilities. Out-of-network providers in these settings are limited to collecting in-network cost-sharing from patients.

Federal No Surprises Act Applies in Montana

The federal No Surprises Act took effect January 1, 2022 and applies to all ERISA and state-regulated health plans in Montana. It prohibits balance billing for emergency services at any facility and for scheduled services provided by out-of-network providers at in-network facilities. Patients pay only in-network cost-sharing for these services.

Montana State Balance Billing Framework

Montana applies the federal No Surprises Act for surprise billing. State law prohibits balance billing in HMO plans.

Emergency Services Are Fully Protected

For emergency care at any hospital or freestanding emergency facility in Montana, patients pay only their in-network cost-sharing regardless of the provider's network status. This includes emergency department physicians, radiologists, anesthesiologists, and other facility-based providers. Providers cannot bill the patient for the balance above in-network rates.

When a patient schedules a non-emergency service at an in-network facility, any out-of-network provider involved in care must obtain advance written consent before billing above in-network rates. Without this consent, the provider is limited to in-network cost-sharing. Consent must be specific, dated, provided at least 72 hours before the service, and separate from general admission paperwork.

Federal Independent Dispute Resolution (IDR)

When a provider and health plan disagree on appropriate payment for a Montana claim subject to NSA protections, either party can initiate the federal IDR process. An independent reviewer selects the winning offer based on the qualifying payment amount, provider training, case complexity, and other federal benchmarks.

How to Dispute a Balance Bill in Montana

  1. Identify the balance bill on the EOB and verify the service was subject to NSA protections.
  2. Confirm no valid written consent was obtained for an out-of-network charge.
  3. Notify the health plan citing the federal No Surprises Act and request an in-network rate adjustment.
  4. File a complaint with the Montana Commissioner of Securities and Insurance if unresolved within 30 days.
