"Out-of-network providers may not bill patients for an amount that exceeds in-network cost sharing, as determined in accordance with the balance billing provisions, when furnishing services at an in-network health care facility. Such balance billing prohibitions will not apply if the patient has been provided with adequate notice as has agreed to waive such requirements pursuant to a valid consent, with certain enumerated exceptions. Providers and facilities will further be required to make certain additional disclosures regarding protections against balance billing, including written disclosures to patients and prominent public displays on-site and online."
