Balance Billing Laws in New Mexico
Your medical billing rights and protections in New Mexico.
New Mexico enacted the Surprise Billing Protection Act (HB 389, 2021), prohibiting balance billing for emergency services and for non-emergency services at in-network facilities when patients have no meaningful choice of provider. The law establishes a state-administered independent dispute resolution process.
Key Protections in New Mexico
Emergency services: Balance billing prohibited for emergency care; patients pay only their in-network cost-sharing amounts
Non-emergency out-of-network care at in-network facilities: Protected when patient has no meaningful choice of provider
State IDR process: New Mexico has its own independent dispute resolution mechanism for provider-insurer payment disputes
Advance notice: Providers must notify patients of their network status before non-emergency services

Additional Notes
New Mexico's Surprise Billing Protection Act took effect January 1, 2022, aligning with the federal No Surprises Act. State law applies to state-regulated plans; federal law covers self-funded ERISA plans.
