Some medical providers will ask patients to waive their rights to NSA protections via a “Surprise Billing Protection Form.” A patient must voluntarily sign the waiver. However, there are situations where providers may not utilize waivers. These circumstances include emergency services and unknown urgent needs during non-emergency care. These settings also include services related to emergency care such as an out-of-network provider at an in-network hospital. Waivers are not allowed for assistant surgeon services or diagnostic services. Finally, waivers aren’t permitted for out of network providers when no in network providers are available at a facility.
