Notice-and-consent: the form that unlocks lawful OON billing
Summary
The notice-and-consent exception lets an out-of-network provider bill beyond the in-network rate for certain non-emergency services at an in-network facility, but only if the patient receives a written notice with a good-faith estimate of the out-of-network charges, signs consent to waive the protections in advance, and the timing rules are met. It cannot be used for emergency or ancillary services, and a standalone office practice rarely needs it at all.

What the exception does
notice and consent is a narrow, opt-in waiver of the No Surprises Act's balance-billing ban. For certain non-emergency services furnished by an out-of-network provider at an in-network facility, the provider may bill beyond the protected amount only if the patient is first given a written notice and voluntarily signs consent to give up the protections for that care 1Ref 1Office of the Federal Register (2026).45 CFR Part 149 — Surprise Billing and Transparency Requirements.The notice-and-consent exception's mechanics: the required elements and standard notice, the seventy-two-hour and three-hour timing rules, the ancillary-services and no-alternative carve-outs, the seven-year retention requirement, and the civil monetary penalty framework.. Without a valid, timely signed consent, the balance-billing ban stands and the provider is limited to the in-network cost-sharing amount 2Ref 2Centers for Medicare & Medicaid Services (2026).No Surprise Billing.That the No Surprises Act restricts balance billing in defined settings, that the default is no balance billing absent a valid waiver, and that CMS hosts the standard notice and the guidance on when the exception does and does not apply..
The key is that consent is the exception, not the rule. The default under the No Surprises Act is that a patient in a protected setting cannot be balance billed at all; the notice-and-consent document is the only mechanism that lifts that default, and it does so only when every element and deadline is satisfied. Reading the No Surprises Act for an office practice, this is the one place the ban can be waived — and even then, only for the specific services the exception allows.
The elements of a valid notice and consent
A valid consent is a specific document, not a line buried in intake paperwork. It must use the standard written notice, state that the provider is out of network, include a good-faith estimate of the out-of-network charges the patient may owe, and, where applicable, list in-network providers who could furnish the same service 1Ref 1Office of the Federal Register (2026).45 CFR Part 149 — Surprise Billing and Transparency Requirements.The notice-and-consent exception's mechanics: the required elements and standard notice, the seventy-two-hour and three-hour timing rules, the ancillary-services and no-alternative carve-outs, the seven-year retention requirement, and the civil monetary penalty framework.. The patient must sign and date it voluntarily, receive a copy, and the notice must be provided in a manner the patient can understand, including in the patient's language where that applies.
The consent has to be genuinely optional. The patient cannot be required to sign as a condition of receiving care, and consent obtained under pressure, or after the fact, does not lift the balance-billing ban 2Ref 2Centers for Medicare & Medicaid Services (2026).No Surprise Billing.That the No Surprises Act restricts balance billing in defined settings, that the default is no balance billing absent a valid waiver, and that CMS hosts the standard notice and the guidance on when the exception does and does not apply.. Because the standard form and its required content are defined, the safest practice is to use the government's standard document rather than draft your own.
The timing rules
The notice and consent must reach the patient far enough ahead to be a real choice, and the deadline depends on how far out the appointment is booked. An appointment scheduled at least seventy-two hours before the service requires delivery no later than seventy-two hours before; an appointment made inside that window requires delivery no later than three hours before the service 1Ref 1Office of the Federal Register (2026).45 CFR Part 149 — Surprise Billing and Transparency Requirements.The notice-and-consent exception's mechanics: the required elements and standard notice, the seventy-two-hour and three-hour timing rules, the ancillary-services and no-alternative carve-outs, the seven-year retention requirement, and the civil monetary penalty framework..
| When the appointment is scheduled | When notice-and-consent must be delivered |
|---|---|
| At least 72 hours before the service | No later than 72 hours before the service |
| Fewer than 72 hours before (same-week or same-day) | No later than 3 hours before the service |
The timing is not a formality. A consent handed over at check-in for a visit that was booked a week earlier is late, and a late consent does not waive the ban 2Ref 2Centers for Medicare & Medicaid Services (2026).No Surprise Billing.That the No Surprises Act restricts balance billing in defined settings, that the default is no balance billing absent a valid waiver, and that CMS hosts the standard notice and the guidance on when the exception does and does not apply.. Calendar the delivery to the scheduling date, not the visit date, so the window is met before the patient arrives.
Where consent is not allowed at all
For a defined set of services, the patient cannot waive the balance-billing protections no matter what they sign. The exception is unavailable for emergency services and for ancillary services — including anesthesiology, pathology, radiology, neonatology, and diagnostic services — as well as items or services furnished by assistant surgeons, hospitalists, and intensivists 1Ref 1Office of the Federal Register (2026).45 CFR Part 149 — Surprise Billing and Transparency Requirements.The notice-and-consent exception's mechanics: the required elements and standard notice, the seventy-two-hour and three-hour timing rules, the ancillary-services and no-alternative carve-outs, the seven-year retention requirement, and the civil monetary penalty framework.. It is also unavailable when there is no in-network provider available to furnish the service, and for unforeseen, urgent medical needs that arise during a visit.
The logic is that consent only means something when the patient had a real alternative. In these situations the patient effectively has no choice — an emergency, an ancillary provider they never selected, or a facility with no in-network option — so the law treats any consent as ineffective and the ban holds 2Ref 2Centers for Medicare & Medicaid Services (2026).No Surprise Billing.That the No Surprises Act restricts balance billing in defined settings, that the default is no balance billing absent a valid waiver, and that CMS hosts the standard notice and the guidance on when the exception does and does not apply.. This is where gap exceptions and the patient's own plan authorizations, rather than a waiver, are the relevant tools.
Does a solo office ever use it?
For most office practices the answer is no, because the balance-billing ban that the exception waives is tied to facility and emergency settings in the first place. A standalone out-of-network office that a patient chooses knowingly is not delivering care inside the protected settings, so there is usually no ban to waive and therefore no notice-and-consent to sign 2Ref 2Centers for Medicare & Medicaid Services (2026).No Surprise Billing.That the No Surprises Act restricts balance billing in defined settings, that the default is no balance billing absent a valid waiver, and that CMS hosts the standard notice and the guidance on when the exception does and does not apply..
What an out-of-network office actually uses instead is the out-of-network superbill: you collect your fee and give the patient an itemized superbill to seek reimbursement from their own plan, which is an ordinary out-of-network billing arrangement rather than a No Surprises Act waiver. The exception becomes relevant only if a clinician also furnishes out-of-network care at an in-network facility — moonlighting at a hospital, for instance — where the ban attaches and the standard notice is the only lawful path to bill beyond it 1Ref 1Office of the Federal Register (2026).45 CFR Part 149 — Surprise Billing and Transparency Requirements.The notice-and-consent exception's mechanics: the required elements and standard notice, the seventy-two-hour and three-hour timing rules, the ancillary-services and no-alternative carve-outs, the seven-year retention requirement, and the civil monetary penalty framework..
Retain it, and the cost of getting it wrong
A signed consent is only worth keeping if you can produce it, so retention is part of the requirement. The provider must retain the written notice and consent for at least seven years, which is the window in which a challenge to the balance bill could arise 1Ref 1Office of the Federal Register (2026).45 CFR Part 149 — Surprise Billing and Transparency Requirements.The notice-and-consent exception's mechanics: the required elements and standard notice, the seventy-two-hour and three-hour timing rules, the ancillary-services and no-alternative carve-outs, the seven-year retention requirement, and the civil monetary penalty framework.. Store it in the chart the same way you store any other legally significant signed document.
Getting the exception wrong is not a paperwork footnote. An unlawful balance bill — one made without a valid, timely consent, or for a service where consent is not permitted — is a No Surprises Act violation that can draw civil monetary penalties of up to ten thousand dollars per violation, on top of having to refund the patient the improperly billed amount 2Ref 2Centers for Medicare & Medicaid Services (2026).No Surprise Billing.That the No Surprises Act restricts balance billing in defined settings, that the default is no balance billing absent a valid waiver, and that CMS hosts the standard notice and the guidance on when the exception does and does not apply.. The one-page notice a practice posts about balance-billing protections is a separate, standing disclosure; it does not substitute for an individual signed consent when the exception is actually being used.
