No Surprises Act Medical Billing: A Compliance Guide for Providers
The No Surprises Act has changed how practices handle everything from out-of-network billing to patient estimates. But the real challenge isn’t just understanding the law—it’s building new workflows that protect your revenue. Getting compliance wrong can cause serious payment delays, surprise write-offs, and expensive disputes. That’s why having a solid No Surprises Act medical billing strategy is so critical. This guide will walk you through creating processes that protect patients, preserve your reimbursement, and reduce your compliance risk without the headache.

This guide explains how the No Surprises Act affects medical billing, what providers need to know about good faith estimates, how the independent dispute resolution process works, and where billing teams should focus their compliance efforts.
Breaking Down the No Surprises Act
The No Surprises Act is a federal law designed to protect patients from certain unexpected out-of-network medical bills. It was created under the Consolidated Appropriations Act of 2021 and applies to many patients with group health plans, individual health insurance coverage, and Federal Employees Health Benefits plans. Certain protections also apply to uninsured and self-pay patients.
In practical terms, the law limits when providers and facilities can balance bill patients for certain out-of-network services. It also requires transparency around expected costs, creates disclosure obligations, and establishes dispute resolution processes for both payer-provider payment disputes and certain patient-provider billing disputes.
For billing teams, the No Surprises Act is not a single checkbox. It touches eligibility, patient intake, estimate generation, claim submission, payer follow-up, denial management, payment posting, patient statements, and documentation retention.
How the No Surprises Act Changes Medical Billing
No Surprises Act medical billing rules affect the revenue cycle in several important ways. The most visible change is the restriction on balance billing in specific out-of-network scenarios, but the operational impact is broader than that.
- Patient cost-sharing must be handled correctly. In protected situations, patient responsibility is generally limited as if the care were in network.
- Out-of-network reimbursement disputes require a defined workflow. Providers may need to use open negotiation and, when eligible, the federal independent dispute resolution process.
- Uninsured and self-pay patients need good faith estimates. Providers and facilities must have a process to generate and deliver expected charge information.
- Notices and consent forms must be controlled carefully. Some situations allow notice and consent, while others do not.
- Documentation matters more than ever. Billing teams need records that show what was provided, when it was provided, and how the patient or payer account was handled.
These requirements make revenue cycle discipline essential. A practice that treats No Surprises Act compliance as an afterthought may see delayed payments, patient complaints, denied balances, or unnecessary payer disputes.
Key Patient Protections Since January 2022
Emergency and Mental Health Services
The No Surprises Act created a major safeguard for patients needing urgent care. For most emergency services, patients can no longer receive surprise bills, even if they are treated at an out-of-network hospital or by an out-of-network clinician. This protection is broad, covering services from the emergency room visit itself to related care from ancillary providers like radiologists or anesthesiologists. It also explicitly includes emergency mental health services. From a billing perspective, this means your practice must limit the patient’s cost-sharing to what they would have paid for in-network care. The health plan is also required to cover these services as if they were in-network, shifting the financial negotiation from the patient to the provider and the payer.
Are Your Services Covered by the No Surprises Act?
The No Surprises Act focuses on specific surprise billing situations. Medical billing teams should pay close attention when a claim involves emergency care, out-of-network services at an in-network facility, or air ambulance services. These situations are especially sensitive because patients often have little control over which provider is involved in their care.
Common examples include:
- Emergency services provided by an out-of-network provider or facility.
- Non-emergency services from certain out-of-network providers at an in-network hospital or ambulatory surgical center.
- Ancillary services, such as anesthesia, pathology, radiology, neonatology, diagnostic services, and certain assistant surgeon services, when covered by the rule.
- Air ambulance services covered by applicable federal surprise billing protections.
Not every claim falls under the same rule, and some states have their own surprise billing laws. A strong billing operation should identify the payer, plan type, service setting, provider network status, and applicable state or federal process before deciding how to bill the account.
Services and Plans Not Covered by the Act
While the No Surprises Act provides broad protections, it doesn’t cover every medical service or health plan. Understanding these exceptions is just as important as knowing the rules. For your billing team, recognizing when the Act does not apply is key to avoiding compliance errors and ensuring you follow the correct billing protocol for every patient encounter. Certain services, facilities, and patient populations fall outside the scope of this federal law, each with its own set of billing considerations that require careful attention from your practice’s administrative and financial staff.
Ground Ambulance Services
One of the most significant exceptions to the No Surprises Act is ground ambulance services. While the law’s protections do apply to air ambulances, they currently do not extend to care provided by ground ambulances. This means that if a patient is transported to a hospital via a ground ambulance that is out-of-network with their health plan, they may still receive a surprise bill for that service. Practices and facilities should be aware of this distinction, especially when coordinating patient transport or advising patients on potential costs. It remains a critical gap in patient protection that billing departments must account for in their workflows.
Excluded Facilities and Health Plans
The No Surprises Act is specific about where its protections apply. The rules cover services delivered in hospitals, hospital emergency departments, and ambulatory surgical centers. However, they generally do not apply to care received in other settings, such as physician offices, clinics, or urgent care centers. While federal regulators have indicated this could change in the future, for now, these facilities are not included. Your billing process must be able to differentiate claims based on the place of service to determine whether the federal surprise billing rules are triggered. You can always review the latest guidance from official sources to stay current on these definitions.
Populations with Existing Protections
The No Surprises Act was designed to fill gaps in commercial insurance, so it doesn’t apply to patients covered by plans that already have robust protections against surprise billing. If your patient has Medicare, Medicaid, TRICARE, Veterans Affairs Health Care, or Indian Health Services coverage, they are already protected from surprise medical bills under the rules of those specific programs. Therefore, the No Surprises Act’s provisions, including its dispute resolution process, do not apply. For the diverse range of specialists we help, from pediatricians to primary care physicians, correctly identifying the patient’s plan is the first step in compliant billing.
Mastering Good Faith Estimates
A good faith estimate is a written estimate of expected charges for an item or service. Under the No Surprises Act, providers and facilities must provide good faith estimates to uninsured and self-pay patients in applicable situations. This requirement is meant to give patients a clearer view of expected costs before they receive care.
Good faith estimate workflows should start before the visit whenever possible. The billing team needs accurate demographic information, service details, expected CPT or HCPCS codes when available, diagnosis information when known, provider and facility details, and any related items or services that may affect the estimate.
When Patients Can Dispute a Bill
Your patients have specific rights when it comes to challenging a bill, and it’s crucial for your team to know the rules. The most common reason for a dispute under the No Surprises Act is a large gap between the good faith estimate and the final bill. Specifically, if your final charges are at least $400 more than the estimate you gave an uninsured or self-pay patient, they can formally dispute the bill. The patient has 120 days from the bill’s date to file this dispute. This process underscores the need for accuracy in your estimates. To prepare for any potential challenges, make sure your practice maintains meticulous documentation that justifies all charges, especially when the final cost is higher than anticipated.
Building Your Good Faith Estimate Workflow
- A standard intake question that identifies uninsured and self-pay patients.
- A process for documenting whether the estimate was scheduled, requested, or updated.
- Clear ownership for gathering expected charge information.
- Templates that include required estimate details and patient-friendly language.
- A delivery method that can be tracked, such as portal message, secure email, mail, or in-person delivery.
- A record retention process that stores the final estimate with the patient account.
Good faith estimates are not the same as guaranteed final bills. Clinical needs can change. Additional services may be required. Still, the estimate should be reasonable based on the information available when it is created.
Practices should also review how estimates connect to patient statements. If the final billed amount is significantly higher than the estimate, an uninsured or self-pay patient may have access to the patient-provider dispute resolution process. That makes estimate accuracy, documentation, and communication critical.
Understanding Balance Billing and Patient Notices
Balance billing happens when an out-of-network provider bills a patient for the difference between the provider’s charge and the amount paid by the health plan, plus any allowed patient cost-sharing. The No Surprises Act prohibits balance billing in certain situations and requires providers to disclose patient protections.
Some out-of-network services may allow notice and consent before care is provided, but this should never be handled casually. Certain services and circumstances cannot be waived through consent. Emergency services and many ancillary services require extra caution. Billing teams should avoid using generic forms without confirming that the situation is eligible for notice and consent.
A practical compliance process should answer four questions before any out-of-network patient balance is pursued:
- Was the patient covered by a plan subject to No Surprises Act protections?
- Did the service type and place of service fall under surprise billing protections?
- If notice and consent was used, was it allowed for this service and completed correctly?
- Does the patient statement reflect the correct cost-sharing amount and not a prohibited balance?
This is where billing accuracy and patient experience overlap. Incorrect balance billing can create financial harm for patients and reputational risk for the practice.
The Notice and Consent Process
While the No Surprises Act restricts balance billing, it does include a narrow exception: the notice and consent process. In some non-emergency situations, you can ask a patient to waive their surprise billing protections and agree to be billed as an out-of-network patient. However, this process should never be handled casually. The patient must provide consent voluntarily at least 72 hours before the service, or on the same day for appointments made within that window. Your billing team should avoid using generic forms without first confirming that the specific service is even eligible for notice and consent. This is a high-risk area, and getting it wrong can invalidate the consent, leaving your practice with a bill that can’t be collected from the patient. Proper medical billing workflows are essential to manage this correctly.
When Consent Cannot Be Requested
It’s critical to know when you absolutely cannot request consent. The No Surprises Act prohibits using the notice and consent process for emergency services, unforeseen ancillary services provided at an in-network facility (like those from anesthesiologists or pathologists), and air ambulance services. These situations require extra caution because the patient has little to no choice in their provider. Attempting to get a waiver for these protected services is a significant compliance misstep. Your front-office and clinical teams need to be trained to recognize these scenarios to protect both the patient and the practice from billing errors.
Informing Patients and Handling Complaints
Clear communication is your best defense against patient complaints and billing disputes. This is where billing accuracy and patient experience truly overlap. An incorrect bill can cause real financial harm to a patient and create serious reputational risk for your practice. Before you send any statement for an out-of-network balance, your team should have a process to verify compliance. This means having clear answers to questions about the patient’s plan, the service type, and whether any consent was properly obtained. A proactive approach to patient billing, supported by strong practice management, ensures you handle patient accounts correctly from the start, reducing confusion and building trust.
Payer and Debt Collector Responsibilities
Providers aren’t the only ones with new obligations under the No Surprises Act. The law also outlines specific responsibilities for health plans and debt collectors. Understanding these rules helps your practice ensure payers are holding up their end of the bargain and that your own patient collection practices remain compliant. When a claim is processed incorrectly by a payer or a balance is pursued improperly, it can create confusion for patients and payment delays for your practice.
Insurance Company Requirements
When a patient receives care protected by the No Surprises Act, the health plan has a critical role to play. Insurance companies are required to process these claims while limiting the patient’s financial responsibility. According to the U.S. Department of Labor, this applies to most emergency services, non-emergency services from out-of-network providers at in-network facilities, and certain air ambulance transports. For these claims, the payer must calculate the patient’s cost-sharing amount (like copayments or deductibles) as if the provider were in-network. This prevents the patient from being hit with a higher out-of-pocket cost simply because they were treated by an out-of-network provider in a surprise situation.
Medical Debt Collection Rules
The No Surprises Act’s protections extend all the way to the collections process. If a bill qualifies as a prohibited surprise bill, that balance cannot be pursued. This is a firm line that applies to both your internal billing team and any third-party collection agencies you work with. As the California Department of Financial Protection and Innovation clarifies, debt collectors are explicitly forbidden from trying to collect on debts that arise from surprise out-of-network bills. This makes it essential for your practice to have a system that flags these accounts correctly, ensuring they are never sent to collections or reported to credit bureaus. Missteps here can lead to serious compliance issues and harm your relationship with patients.
How Federal and State Laws Interact
One of the most complex aspects of surprise billing compliance is figuring out which law applies. The No Surprises Act is a federal law, but it doesn’t automatically replace existing state laws. Instead, it establishes a minimum level of patient protection nationwide. As CMS explains, if a state has its own surprise billing law that offers equal or greater protection for patients, that state law will generally apply. This means your practice must be aware of both federal regulations and any specific rules in the states where you provide care. Keeping track of this patchwork of regulations is a significant administrative burden, which is why many practices rely on specialized billing partners to manage compliance.
The scope of these laws can also differ. For example, the federal act applies to specific facility types, such as hospitals, hospital outpatient departments, and ambulatory surgical centers. However, it may not cover services provided in other settings like clinics or urgent care centers. Some state laws, on the other hand, might have a broader reach and include these other facility types. This variation requires your billing team to verify which rules—federal, state, or a combination of both—apply to each claim. The correct path depends on the patient’s health plan, the service location, and the specific services rendered, making diligent, claim-by-claim attention essential.
Making Sense of the IDR Process
The federal independent dispute resolution process, often called IDR, gives eligible providers, facilities, and health plans a way to resolve certain out-of-network payment disputes. It is not the first step. In many cases, the process begins when a provider receives an initial payment or denial from the health plan and then starts a 30-business-day open negotiation period.
If the parties do not reach an agreement by the end of open negotiation, either party may be able to initiate the federal IDR process within the required timeframe. According to CMS, disputing parties submit payment offers and supporting information to a certified IDR entity. The certified IDR entity selects an offer, and payment must be made after the determination according to the applicable rules.
For billing departments, the IDR process requires organized claim documentation. Teams should be ready to retrieve:
- Claim numbers and payer correspondence.
- Dates and locations of service.
- Procedure codes, modifiers, and place-of-service codes.
- Initial payment or denial documentation.
- Evidence of open negotiation activity.
- Any supporting information used to justify the payment position.
Because deadlines matter, IDR-related accounts should not sit in a general denial queue. They need a dedicated tracking system, clear escalation rules, and staff who understand how the process differs from routine payer appeals.
Your No Surprises Act Medical Billing Checklist
Compliance becomes easier when the billing team translates the law into repeatable checkpoints. Use the following checklist as a starting point for internal review.
| Billing area | Compliance checkpoint | Why it matters |
|---|---|---|
| Patient intake | Identify insured, uninsured, and self-pay status accurately. | Determines whether good faith estimate or plan-based protections may apply. |
| Eligibility verification | Confirm coverage, network status, plan type, and patient responsibility. | Prevents incorrect cost-sharing and avoidable billing disputes. |
| Estimate process | Create, deliver, and retain good faith estimates when required. | Supports transparency for uninsured and self-pay patients. |
| Notice and consent | Use only when allowed and document completion before care. | Reduces the risk of prohibited balance billing. |
| Claim review | Flag out-of-network emergency, facility-based, and air ambulance scenarios. | Helps route claims into the correct payer and patient billing workflow. |
| IDR tracking | Monitor open negotiation deadlines and IDR eligibility. | Protects reimbursement opportunities when payment disputes qualify. |
| Patient statements | Review balances before sending statements on protected claims. | Prevents billing patients for amounts that should not be billed. |
Practices that already follow strong revenue cycle management best practices will have an advantage because No Surprises Act compliance depends on the same fundamentals: accurate intake, clean documentation, timely follow-up, and disciplined payment posting.
Are You Making These No Surprises Act Billing Errors?
Many compliance problems happen because normal billing habits are applied to accounts that require a different process. The following mistakes are common and preventable.
1. Assuming Network Status is Just for Payers
Network status affects more than reimbursement. It can determine whether balance billing protections apply, whether patient cost-sharing needs to be recalculated, and whether a payment dispute should be tracked for open negotiation or IDR.
2. Sending Bills Before a Compliance Check
Patient statements should not be released automatically when a claim involves a potentially protected surprise billing scenario. A final review can prevent improper balances from reaching the patient.
3. Not Linking Estimates to Final Bills
If good faith estimates are created in one system and final patient statements are generated somewhere else, discrepancies can go unnoticed. Estimates should be visible to billing staff when the account is reviewed.
4. Missing Critical Dispute Deadlines
IDR timelines are not the same as standard denial follow-up. If an account is eligible for open negotiation or IDR, the billing team needs deadline tracking from the moment the initial payment or denial is received.
5. Letting Your Documentation Slide
Documentation is the backbone of compliance. If the practice cannot show when an estimate was delivered, what notice was provided, or how a disputed claim was handled, it becomes much harder to defend the billing process.
If compliance tasks are stretching your internal team thin, AMS Solutions can help evaluate billing workflows, reporting, and practice management processes so your revenue cycle is more controlled from intake through collections.
How to Create a Compliant Medical Billing Workflow
No Surprises Act compliance works best when it is built into the revenue cycle instead of added after the claim goes wrong. For most practices, that means creating a shared workflow between front desk staff, schedulers, billers, coders, managers, and outside billing partners.
Start with these steps:
- Map the patient journey. Identify where insurance status, self-pay status, network status, and service details are captured.
- Create account flags. Use system notes or workflow statuses for accounts that may involve good faith estimates, notice and consent, or surprise billing protections.
- Standardize forms and templates. Keep estimate letters, disclosure notices, and internal checklists consistent.
- Train staff by role. Schedulers do not need the same training as denial specialists, but each role must know its compliance responsibilities.
- Audit patient balances. Review protected scenarios before sending statements or placing accounts in collections.
- Track payer disputes separately. Use a workqueue for open negotiation and IDR-related accounts.
- Review results monthly. Monitor estimate errors, patient complaints, payer disputes, write-offs, and delayed payments.
Medical practices should also confirm that credentialing records, payer contracts, and provider enrollment data are current. Accurate enrollment supports cleaner claims and reduces network-status confusion. If credentialing is a pain point, review AMS Solutions’ medical credentialing services for support with provider enrollment and ongoing maintenance.
Avoiding Claim Rejections and Denials
Beyond the complexities of the No Surprises Act, a healthy revenue cycle depends on mastering the fundamentals of claim submission. Claim rejections and denials are often the biggest source of administrative friction and delayed payments for a practice. The good news is that most of these issues are preventable. By focusing on accuracy and building strong front-end processes, your team can stop common errors before they ever leave your system.
Common Reasons for Claim Denials
Many claim denials happen because of simple mistakes that occur long before a claim is even submitted. According to one analysis, some of the most common denials in medical billing include incorrect patient information, like a wrong birth date or insurance ID. Another frequent problem is failing to get prior authorization for services that require it; your team should always check authorization requirements when scheduling. Filing claims after the payer’s deadline is another easy way to lose revenue. Finally, if your clinical documentation doesn’t clearly explain *why* a service was medically necessary, you risk a denial. Building strong checkpoints at intake and before submission is your best defense against these recurring issues.
Is It Time to Outsource Your Medical Billing?
A practice should consider outside billing support when No Surprises Act requirements are creating delays, inconsistent patient communication, missed payer follow-up, or uncertainty around out-of-network claim handling. Compliance-heavy billing can quickly overwhelm an internal team that is already managing authorizations, coding questions, denials, payment posting, and patient calls.
Outsourcing does not remove the practice’s need for oversight, but the right partner can provide structure. A dedicated billing team can help standardize intake workflows, monitor claim status, follow payer correspondence, track denial patterns, and escalate accounts that require special handling.

Frequently Asked Questions About No Surprises Act Medical Billing
Does the No Surprises Act apply to every medical bill?
No. The No Surprises Act applies to specific surprise billing situations and certain transparency requirements. It does not apply to every medical bill, and some patients are covered by other programs or state laws. Billing teams should review the plan type, service setting, provider network status, and applicable rules before deciding how to handle a balance.
Who needs a good faith estimate?
Good faith estimate requirements generally apply to uninsured and self-pay patients in applicable situations. Practices should identify these patients early, prepare the estimate using the information available, deliver it through a trackable process, and keep a copy in the patient record.
What is the IDR process?
The independent dispute resolution process is a federal process for certain out-of-network payment disputes between providers, facilities, and health plans. It usually follows a 30-business-day open negotiation period. If no agreement is reached and the dispute qualifies, a certified IDR entity reviews the offers and selects a payment amount.
Can a patient waive No Surprises Act protections?
Sometimes notice and consent may be allowed, but not in all circumstances. Certain emergency and ancillary services cannot be handled through a simple waiver. Practices should use approved forms, confirm eligibility for notice and consent, and document the process carefully.
Why is medical billing documentation so important for compliance?
Documentation shows what the practice knew, what the patient received, what was billed, and how disputes were handled. Strong documentation supports compliance, improves payer follow-up, and helps resolve patient questions before they become complaints.
