No Surprises Act means the “No Surprises Act,” which was enacted to curtail “surprise billing” in Title I of Division BB of the Consolidated Appropriations Act of 2021, including the regulations and binding guidance issued thereunder, which generally governs patient cost sharing, balance billing, and payments to providers/facilities for emergency services (including certain post-stabilization care) rendered in out-of-network facilities, services rendered by out-of-network providers in in-network facilities, and services rendered by air ambulance providers.
