No Surprises Act Questions Answered

Which Plans and Providers Does the No Surprises Act Cover, and Which Does It Not?

The No Surprises Act protects people covered by employer group health plans, individual and group health insurance, and Federal Employees Health Benefits (FEHB) carriers. CMS states this in its Overview of Key Consumer Protections, revised June 2026. If the patient's coverage is one of those types, the surprise billing rules can apply to the claim.

The Act does not reach government programs that have their own balance billing protections. For a billing office, the plan type on the eligibility response is the first thing to read, before any open negotiation clock is started.

CMS also excludes disease-specific plans such as cancer-only policies, hospital indemnity and accident-only policies, and stand-alone vision or dental plans. A major medical plan that includes dental or vision benefits can still carry the protections for those covered services.

Which Facilities Count When an Out-of-Network Provider Treats a Patient at an In-Network Site?

For non-emergency care, the Act applies when an out-of-network provider treats a patient during a visit to one of four in-network facility types. CMS lists them in footnote 2 of its key protections document: a hospital, a hospital outpatient department, a critical access hospital and an ambulatory surgical center.

A visit to an in-network setting outside those four does not trigger the non-emergency protections. CMS gives community health clinics and some doctors' offices as examples. A visit to an out-of-network facility is also outside this part of the Act.

What About Emergency Care?

Emergency protections attach to hospital emergency departments and to independent freestanding emergency departments, plus hospital departments that care for patients once they are stabilized. The out-of-network provider is covered too, whether physician, physician assistant or nurse practitioner. Under 45 CFR 149.410(a), a nonparticipating emergency facility or provider must not bill the patient more than the in-network cost-sharing amount for emergency services.

Where Does Urgent Care Fit?

An urgent care center is covered for emergency services only if it is licensed by its state to provide emergency services and is geographically separate and distinct from, and licensed separately from, a hospital. CMS makes this point in footnote 4 of the same document, which also names behavioral health crisis facilities. A walk-in urgent care that is not licensed that way is an in-network or out-of-network office setting, and the facility list above decides the non-emergency question.

Freestanding ER groups should confirm their state license before they rely on the emergency protections in a payer dispute. The documents that go in an open negotiation notice are on the open negotiation page.

Who Do You Contact with a No Surprises Act Question or a Possible Violation?

Call the No Surprises Help Desk at 1-800-985-3059, open 8 a.m. to 8 p.m. ET, 7 days a week, according to the CMS tips for disputing parties page. The same page says to send questions about federal IDR to the Federal IDR mailbox at FederalIDRQuestions@cms.hhs.gov.

CMS also says the help desk is where to report potential violations of the process. Its complaint page states you can submit a complaint if you believe a facility, provider or insurer is not following the rules. That page does not describe the steps beyond a phone number and a link to help resources, and it names no penalty amount, so we do not quote one here.

• Questions about a federal IDR case: the mailbox above, with the dispute reference number in the subject line.
• Questions about the rules or a suspected violation: the help desk.
• Patient questions: the key protections document points patients to state Consumer Assistance Programs and the state Department of Insurance.

Why Do IDR Emails Seem to Go Missing?

CMS tells parties to check the junk folder for messages from FederalIDRQuestions@cms.hhs.gov. If your organization's filters block them, CMS says to ask IT to add the address to the safe senders list. Do this before you file, because entity notices and requests for information carry short response windows.

CMS also warns that wrong contact details cause delays in processing. The practical fix is one shared mailbox, monitored daily, listed on every dispute and open negotiation notice.

What Should You Do When an Out-of-Network Payment Looks Too Low?

Check whether the claim is eligible, read what the payer disclosed about the qualifying payment amount, and start the clock if it is. The 30-business-day window to send an open negotiation notice begins the day you receive the initial payment or denial, so the first review has to be fast.

Not every low payment is worth a dispute. A short payment on a small claim may cost more to dispute than it returns, because each party pays an administrative fee and an entity fee. Group claims only where the batching rules allow it; see batching claims.

What Happens After an IDR Decision, and Why Can Payment Still Be Late?

Under 45 CFR 149.510(c), the selected amount, less the initial payment and patient cost sharing, is due to the provider within 30 calendar days of the determination. The regulation makes the decision binding in the absence of fraud or evidence of intentional misrepresentation of material facts, and it is not subject to judicial review except in the cases 9 U.S.C. 10(a)(1) through (4) describe.

Late payment is a collections problem, not an appeal. Section 149.510 text sets out no enforcement procedure for a late payment. Track the 30 calendar days from the decision date, post the payment when the remittance arrives and escalate to the payer in writing when the date passes. CMS lists the No Surprises Help Desk for reports of potential violations of the process.

Does an Award Set the Rate for Later Claims?

No. A determination decides the payment for the claims in that dispute. After a single determination, the party that started the dispute cannot start another against the same other party for the same item or service for 90 calendar days, under 149.510(c)(5)(vii)(B). Claims whose open negotiation ended during that suspension can be filed in the 30-business-day period that begins the day after the suspension ends. For a batched determination the suspension is 30 business days.

A later claim needs its own open negotiation and, if that fails, its own dispute. Any standing rate between you and a payer comes from a contract, which is a payer contracting question, not an IDR one.

How We Handle No Surprises Act Questions and Disputes

A designated NSA team owns every case. We verify benefits for every patient the client sends each day, confirm the service was in an emergency department or freestanding emergency department, and read the remittance remark codes. Each case starts from a dedicated email address, with printed documents and proof of submission in a separate folder.

We go back on older claims as far as payer filing limits allow, within the fixed federal IDR windows. Reports are monthly and customized, with day-to-day updates by email. We show win rates by payer on a call, as totals only, and we do not share references or sample dispute packages because they contain other clients' and patients' information.

NSA and IDR work is a monthly retainer quoted on a call. Our out-of-network billing and IDR service page explains the workflow. If you have a claim that does not fit the answers above, book a call and send us the remittance.
