What is Arizona Surprise Billing Law?
Arizona does not have a comprehensive state surprise billing law. The federal No Surprises Act (NSA), effective January 1, 2022, is the primary source of surprise billing protections for Arizona patients. The NSA applies to all health plans in Arizona, both state-regulated and ERISA self-funded plans. Arizona Revised Statutes §20-1376 provides limited additional emergency service protections.
Emergency Care Protections
Under the NSA, patients pay only their in-network cost-sharing amounts for emergency care, regardless of the provider's network status. Out-of-network providers cannot charge patients the difference between their bill and the in-network rate. The insurer is responsible for paying the provider at appropriate rates.
Scheduled Services at In-Network Facilities
When patients receive scheduled services at in-network facilities from out-of-network providers, they pay only in-network cost-sharing. Out-of-network providers cannot balance bill without the patient's advance written consent. Facilities must provide notice if out-of-network providers may be involved.
Qualifying Payment Amount and IDR
The NSA establishes a qualifying payment amount (QPA) that determines how much insurers must pay out-of-network providers. When a provider and insurer disagree on the appropriate payment rate, they can request independent dispute resolution (IDR). Federal arbitrators resolve these disputes using federal benchmarking rules.
Good Faith Cost Estimates
Out-of-network providers must provide good-faith cost estimates before scheduled services. These estimates help patients understand their potential financial responsibility and make informed decisions about out-of-network treatment.
Advance Consent
Patients cannot waive NSA protections for emergency services. For scheduled services, patients may provide advance written consent to receive care from out-of-network providers, but this consent cannot apply to emergency situations.

Frequently Asked Questions
Does the No Surprises Act cover all surprise bills in Arizona?
The No Surprises Act covers emergency services, post-stabilization services, and scheduled services at in-network facilities by out-of-network providers. It does not cover all surprise bills; services at out-of-network facilities with out-of-network providers are generally not protected unless they qualify as emergency or post-stabilization care.
Can I waive surprise billing protections in Arizona?
The No Surprises Act does not allow patients to waive protections for emergency services. For scheduled nonurgent services at in-network facilities, patients may provide advance written consent to receive care from out-of-network providers and understand their potential liability, but this only applies to elective services.
How to Challenge a Surprise Bill in Arizona
- Request an itemized bill and verify service type — Obtain a detailed bill showing each service, charge, and the provider's network status. Confirm whether the service was emergency care, post-stabilization care, or scheduled service at an in-network facility.
- Notify your health plan of NSA protections — Contact your insurer and explain that the service qualifies for federal No Surprises Act protection, requiring them to pay the provider at in-network rates.
- Ask your plan to pay the claim at in-network rates — Request that your plan adjust the claim and pay the out-of-network provider at in-network rates, limiting your liability to in-network cost-sharing only.
- File a complaint with CMS if unresolved — If your plan denies the adjustment, file a formal complaint at cms.gov/nosurprises with the Centers for Medicare and Medicaid Services.
