Balance Billing Laws in Arizona
Your medical billing rights and protections in Arizona.
Arizona has limited state-level balance billing protections. The state relies primarily on the federal No Surprises Act for consumer protections against surprise billing, which has been in effect since January 1, 2022.
Key Protections in Arizona
Emergency services: Federal NSA limits out-of-network emergency cost-sharing to in-network levels
Out-of-network at in-network facility: No surprise billing from out-of-network providers at in-network facilities without advance consent
Transparency: Health plans must provide explanation of benefits within 30 days, and providers must give advance cost estimates
Filing Information
Within 1 year of receiving the bill for federal NSA disputes
Additional Notes
Arizona consumers can file complaints with the state Department of Insurance or use the federal complaint process through CMS for No Surprises Act violations.
