For out-of-network emergency services and services received from nonparticipating providers at in-network facilities, the NSA caps patients' financial responsibility and creates a dispute resolution process for providers and payors to settle payment disputes.
State balance billing laws will play a major part in how stakeholders operationalize the NSA's requirements. This is because Congress drafted the NSA so that it would not apply where a state has itself legislated a remedy to surprise billing.
Specifically, if a state law applies to the patient's health care services and constitutes a specified state law, then it completely supplants the NSA's provisions regarding patient cost-share calculations, provider payments and dispute resolution.
