Good Faith Estimates: Your Right to Know Costs Before Treatment

Introduction: Your Legal Right to Upfront Pricing

There is a deeply reasonable expectation that most people bring to medical care - that before spending thousands of dollars on a procedure, they should have some idea what that procedure will cost. It is an expectation that holds in virtually every other high-stakes financial transaction in American life. When you buy a car, hire a contractor, or take out a mortgage, you receive a binding or near-binding estimate before you commit. You can shop, compare, and make an informed decision.

Medicine has historically operated as though that expectation does not apply - as though the complexity of healthcare, the urgency of illness, and the opacity of insurance contracts justify a system where patients routinely receive bills weeks or months after care that bear no resemblance to anything they were told in advance. The result has been a medical billing environment where surprise is the norm, where a patient who schedules a non-emergency procedure genuinely cannot know what they will owe, and where financial harm from healthcare costs is as much a function of opacity as of the underlying prices themselves.

That began to change in 2022. Under the No Surprises Act - a landmark piece of federal legislation that took effect January 1, 2022 - patients who are uninsured or self-pay, or who request one when scheduling a service, have a legal right to a Good Faith Estimate before receiving care. For the first time, providers are required to put their expected charges in writing, in advance, in a format patients can actually use.

This guide explains what a Good Faith Estimate is, who is entitled to one, how to request it, what it should contain, what happens if your final bill exceeds it, and where the law’s protections fall short. It is not a short guide, because this topic is not simple - but if you read it, you will know more about this right than the majority of patients and, frankly, more than many providers who are required to honor it.

What Is a Good Faith Estimate?

A Good Faith Estimate - often shortened to GFE - is a written document that tells you the expected cost of a scheduled healthcare service before you receive that service. It is not a quote in the legal sense, and it is not a contract. But it is a formal, required disclosure that carries real consequences when the final bill deviates significantly from what it says.

The requirement comes from the No Surprises Act, which was signed into law in December 2020 and took effect for most purposes on January 1, 2022. The Act was primarily aimed at eliminating surprise out-of-network bills - situations where patients received care at an in-network facility but were billed by an out-of-network provider they never chose and never agreed to pay. The Good Faith Estimate requirement is a companion provision that addresses a different but related problem: the inability to know what care will cost before you receive it.

Who Must Provide a Good Faith Estimate

The obligation to provide a Good Faith Estimate falls on providers and facilities - hospitals, outpatient surgery centers, physician practices, imaging centers, laboratories, and any other entity that provides a healthcare item or service. This includes:

• Primary care physicians and specialists
• Hospitals and hospital outpatient departments
• Ambulatory surgery centers
• Mental health and substance use disorder providers
• Physical, occupational, and speech therapists
• Dentists (for services not covered by dental insurance)
• Diagnostic and imaging centers
• Home health agencies

The key qualifier is that the provider must participate in the healthcare marketplace - meaning they accept payment from patients or insurers. Providers who operate entirely outside the insurance system (rare, but they exist) have different obligations.

When a Good Faith Estimate Is Required

The law requires providers to automatically provide a Good Faith Estimate in two circumstances:

For uninsured and self-pay patients: If you do not have insurance, or if you have insurance but choose not to use it for a particular service, your provider is required to give you a Good Faith Estimate before scheduling or providing care. This requirement is automatic - you should not have to ask.

When requested by an insured patient: If you have insurance and you ask for a Good Faith Estimate when scheduling a service, the provider must give you one. This applies to scheduled services - meaning services that are not immediately necessary due to an emergency.

There is an important timing element: providers are required to provide the GFE within a specific window after you schedule a service. If you schedule a service at least three business days in advance, you must receive the GFE within one business day of scheduling. If you schedule at least ten business days in advance, the GFE must arrive within three business days.

The GFE in the Context of the No Surprises Act

The Good Faith Estimate provision is one piece of a broader patient protection framework. Understanding where it fits helps clarify both its power and its limits.

The No Surprises Act also prohibits balance billing by out-of-network providers in emergency settings and by out-of-network providers at in-network facilities in certain non-emergency situations. It created an independent dispute resolution process for disagreements between providers and insurers about payment. And it established transparency requirements that require providers and insurers to disclose information about costs, coverage, and networks in formats patients can actually use.

The GFE is the provision most directly relevant to the pre-care experience - the moment when you are deciding whether and where to get a service, and at what cost. For more on the full framework, see our guide on your rights under the No Surprises Act.

How to Request a Good Faith Estimate

Knowing you have a right to a Good Faith Estimate is only useful if you know how to exercise it. In practice, the automatic provision of GFEs - particularly for insured patients - is inconsistent. Many providers comply reliably. Many do not. The safest approach is to request one explicitly, in writing, at the time you schedule any non-emergency service.

Step-by-Step: Requesting Your GFE

Step 1: Request at the time of scheduling. When you call to schedule an appointment or procedure, make the request immediately. Do not wait until you arrive for the appointment. The legal clock for when the provider must deliver the GFE starts at the moment of scheduling, so the earlier you request it, the sooner you receive it.

Step 2: Use clear, specific language. You do not need to cite the specific statute or use legal language. A simple, direct request is sufficient:

“I would like a Good Faith Estimate for this service before my appointment. Can you send that to me in writing?”

If you want to be more specific:

“Under the No Surprises Act, I’m requesting a Good Faith Estimate for the services we’ve just scheduled. When can I expect to receive it?”

Naming the law helps signal that you know your rights and expect compliance. Most billing staff recognize the term.

Step 3: Confirm the delivery method and timeline. Ask how you will receive the GFE - by mail, email, or patient portal - and when to expect it. Per federal regulations, if you schedule a service at least three business days in advance, the GFE must arrive within one business day. If scheduling at least ten business days out, the window is three business days.

Step 4: Follow up in writing. After the call, send a brief email or patient portal message confirming your request. Something like:

“Following our phone call today, I am confirming my request for a Good Faith Estimate for my appointment scheduled for [date]. Please send it to [email address] at your earliest convenience.”

A written record matters. If the provider fails to deliver the GFE, this documentation supports any complaint you file later.

Step 5: If the estimate doesn’t arrive, follow up. If you do not receive the GFE within the required window, call the billing department and ask again. Reference your written request. If a second request produces nothing, you can file a complaint with the Centers for Medicare and Medicaid Services (CMS) at cms.gov/nosurprises/consumers.

When to Ask for More Than One GFE

A complex medical event - surgery, imaging, a specialist referral - often involves multiple providers. The surgeon who performs your procedure, the anesthesiologist who administers sedation, and the facility where the procedure happens may all send separate bills. Under the law, your primary provider (the one you scheduled with) is responsible for coordinating and including expected charges from co-providers in the GFE. Ask explicitly whether the estimate covers all expected providers.

If you know other providers will be involved - your surgeon mentions an anesthesiologist, or a hospital suggests you will need a post-procedure imaging scan - ask about those charges specifically. If they are not included in the GFE you receive, request a revised one that includes them.

For Insured Patients: The GFE Alone May Not Be Enough

If you have insurance, the GFE shows what the provider expects to charge - but your actual out-of-pocket cost depends on your plan’s cost-sharing, deductible status, and network coverage. The GFE will not tell you what your insurer will pay and what you will owe. For that, you need to contact your insurer directly and ask for a cost estimate based on your specific plan. Some insurers provide cost estimator tools through their online portals; others require a phone call.

The GFE and your insurer’s cost estimate together give you the most complete picture. Neither alone is sufficient. For uninsured and self-pay patients, the GFE is the primary tool - and the dispute rights it triggers are stronger and better defined.

What Should Be Included in a Good Faith Estimate

A compliant Good Faith Estimate is not just a number on a page. Federal regulations specify what a GFE must contain. Knowing the requirements lets you identify an incomplete or non-compliant GFE - and request a corrected one.

Required Elements

A properly completed Good Faith Estimate must include all of the following:

Your name and date of birth. This confirms the GFE is specific to you and not a generic price sheet.

A clear description of the expected items and services. This includes the specific diagnosis codes, procedure codes (CPT codes), and service descriptions for every item expected to be billed. It should not be a vague summary (“surgery and related services”) - it should enumerate the components.

Expected charges for each item and service. Each line item should carry a specific dollar amount representing what the provider expects to bill. This is the chargemaster or list price - what the provider will actually charge before any insurance adjustments.

Diagnosis codes (ICD-10) and service codes (CPT/HCPCS). These are the standardized codes the provider will use to bill. Their presence in the GFE allows you to verify later that you were billed for what was estimated, and not for additional services not discussed.

Facility fees, if applicable. If the service will be performed at a hospital or hospital-owned outpatient facility, the GFE must include any expected facility fees - a category of charge that routinely surprises patients because it is separate from the physician’s fee and often larger.

Information about other providers expected to participate in your care. The primary provider’s GFE should include expected charges from any other providers involved in the scheduled service - anesthesiologists, assistants, labs, radiologists. These may be listed separately or as a combined total, but they should be there.

The GFE’s date of issue and expected service date. A GFE has a limited useful life - a GFE issued today may not reflect prices six months from now. Knowing when it was issued and when the service is scheduled helps you assess whether it is still current.

A statement of your rights. A compliant GFE must include language explaining that you have the right to dispute your bill if it exceeds the GFE by more than $400.

What a GFE Looks Like in Practice

In the best cases, a GFE reads like an itemized pre-bill - a table with procedure codes, descriptions, and expected charges listed line by line, followed by a total. In practice, many GFEs are less detailed than this ideal. Some providers issue GFEs that contain only a global estimate without line-item detail. Some omit co-provider charges. Some fail to include required codes.

If the GFE you receive is vague, missing required elements, or appears to cover only the provider’s own charges without addressing others involved in your care, you have the right to request a corrected, complete estimate. You can reference federal regulations (45 CFR § 149.610 for providers subject to ERISA, or the parallel CMS regulations for providers in the individual and small group market) if the billing department pushes back.

Keeping Your GFE

Retain your Good Faith Estimate - as a physical document or digital file - until you have received and resolved your final bill. You will need it if you need to dispute a bill that exceeds the estimate. Most billing disputes are resolved within a few weeks of filing; keeping the GFE accessible during this period matters.

---

What If Your Bill Exceeds the Good Faith Estimate?

This is where the GFE shifts from a disclosure document to an enforcement tool. Federal law creates a formal dispute resolution process for patients whose final bills significantly exceed their Good Faith Estimate. Understanding this process - and when it applies - is key.

The $400 Threshold

The trigger for the dispute process is a specific dollar amount: $400. If your final bill exceeds your Good Faith Estimate by more than $400, you have the right to initiate a patient-provider dispute resolution process through the federal government.

This threshold applies per provider per GFE - not to the total bill across all providers. If multiple providers were involved and each issued separate GFEs, the $400 threshold applies to each separately.

The $400 figure is a floor, not a ceiling on your rights. If your bill exceeds the estimate by $40, you can still dispute it with the provider directly - you simply do not have access to the formal federal dispute resolution process at that level. For the formal process, the deviation must exceed $400.

How to Dispute a Bill That Exceeds Your GFE

Step 1: Compare your final bill to your GFE carefully. When your bill arrives, compare it line by line against your GFE. Identify where the charges diverged. This comparison serves two purposes: it tells you whether the difference triggers the formal dispute process, and it helps you understand what actually changed - whether new services were added, existing services were coded differently, or the provider simply billed more than estimated.

Step 2: Contact your provider first. Before initiating the federal dispute process, contact the provider’s billing department and explain that your final bill exceeds your Good Faith Estimate by more than $400. Some billing departments will review and correct errors at this stage without requiring a formal dispute. Ask specifically what caused the discrepancy. If the explanation is unsatisfactory - or if they refuse to engage - proceed to the formal process.

Step 3: Submit a dispute to CMS. The formal dispute process is administered by the Centers for Medicare and Medicaid Services. You can initiate it online at cms.gov/nosurprises/consumers. The process requires you to submit:

• A copy of your Good Faith Estimate
• A copy of your final bill
• An explanation of the discrepancy as you understand it

Step 4: Wait for the determination. Once you submit a dispute, CMS will notify your provider. The provider has the opportunity to explain or justify the discrepancy. A federal reviewing entity then determines whether the original GFE or the higher bill represents the appropriate charge. The entire process is designed to conclude within 30 business days.

Step 5: Do not pay the disputed amount while the process is pending. You are not required to pay the disputed portion of your bill while the dispute is under review. The provider cannot send the disputed amount to collections during this period without violating federal law.

When the Provider Can Legitimately Bill More

The Good Faith Estimate does not mean your bill can never exceed the estimate. There are situations where a higher bill is legally permissible:

• Your condition or treatment changed. If your provider discovers during the procedure that additional work is necessary - a surgery that reveals a complication requiring additional repair, for example - the final bill may legitimately exceed the GFE. The provider should be able to document why.
• You requested additional services. If you chose to add services not included in the original estimate, the additional charges are valid.
• The time gap was significant. A GFE is a snapshot in time. If substantial time passed between the estimate and the service, price changes may be reflected in the final bill. This is why the date of issue matters.

Legitimate deviations are the exception, not the rule. If the deviation cannot be explained by changed circumstances, you have a strong case for dispute.

Limitations: What the Good Faith Estimate Does Not Cover

The GFE is a meaningful protection, but it has real limits. Understanding them prevents both over-reliance on the estimate and under-use of other protections that may be more relevant to your situation.

Insured vs. Uninsured: A Significant Divide

The strongest GFE protections apply to uninsured and self-pay patients. For this group, the GFE represents the actual prices they will be expected to pay, the $400 dispute threshold is clearly applicable, and the federal dispute resolution process is designed to produce a binding outcome.

For insured patients, the picture is more complicated. Insured patients are entitled to request a GFE, and providers must supply one. But the GFE for an insured patient shows the provider’s expected charges - not the patient’s expected out-of-pocket cost, which depends on the plan’s network status, deductible, copays, coinsurance, and out-of-pocket maximum. The dispute process for insured patients whose bills exceed GFEs is also less well-defined in current regulation than for uninsured patients.

This means that for insured patients, the GFE is most valuable as a shopping and comparison tool - a way to understand what providers are charging before your insurer adjusts those charges. It is less directly useful as an enforcement mechanism.

Emergency Care Is Excluded

As noted earlier, the GFE requirement does not apply to emergency services. When you receive emergency care, the timing necessary to produce and deliver a GFE is incompatible with the urgency of treatment. The No Surprises Act addresses emergency billing through separate protections - out-of-network emergency care must be billed as if in-network - but not through the GFE mechanism.

It Does Not Cover Every Provider

The GFE you receive from your primary scheduled provider should include expected charges from co-providers. But if an unexpected provider becomes involved in your care - a specialist called in during a procedure, a lab you were not told would be used - their charges will not appear in your GFE, and you may face a bill you had no way to anticipate. This is not a loophole so much as a practical limitation: a GFE can only anticipate what is planned.

It Does Not Account for Insurance Adjustments

The charges listed in a GFE are typically based on the provider’s list prices - the amounts billed before insurance negotiates them down. If you have insurance, your actual payment will be determined by your insurer’s contracted rates and your plan’s cost-sharing structure, neither of which appears in the GFE. The estimate gives you a ceiling, not a floor, on what you might owe if you have coverage.

It Is Not a Guarantee of Insurance Coverage

A Good Faith Estimate does not represent any commitment by your insurance company to cover the services listed. Coverage decisions are made by the insurer based on your specific plan’s terms, and a service that appears in a GFE may still be denied. Always verify coverage separately with your insurer before relying on a GFE as a complete picture of your costs.

Frequently Asked Questions

Does my provider have to give me a Good Faith Estimate even if I have insurance?

Yes, with a caveat. If you have insurance and you request a GFE when scheduling a service, your provider is legally required to give you one. However, the estimate will show the provider’s expected charges - not what you will personally owe after your insurance applies. For self-pay and uninsured patients, the GFE is automatically required without a request. For insured patients, you need to ask.

What if my provider refuses to give me a Good Faith Estimate?

If your provider refuses a legitimate GFE request, you can file a complaint with the Department of Health and Human Services at hhs.gov/nosurprises. Providers who fail to comply with the GFE requirement are subject to federal penalties. Before filing a formal complaint, escalate within the provider’s billing department and ask to speak with a supervisor - some non-compliance is inadvertent rather than intentional.

Can I use the GFE to negotiate my bill before I receive care?

Absolutely. The GFE is actually more useful as a pre-care negotiating tool than as a post-care dispute mechanism. If the estimate reveals charges that seem high, you can ask the provider directly whether those charges are negotiable - particularly if you are uninsured or self-pay. Many providers, especially hospitals, will accept less than their chargemaster rates before care is rendered. Having the GFE in hand gives you a documented basis for that conversation.

What if I cannot understand what the GFE contains?

GFEs are generated by billing departments and often use procedure codes and clinical terminology that are opaque to patients without medical or billing backgrounds. If your GFE is unclear, you can ask the provider’s billing department to walk you through it in plain language. You can also use tools like NilesAI’s resources to look up what specific codes mean and whether the expected charges fall within a normal range. If you believe something is wrong but cannot identify it yourself, this is a situation where an hour of consultation with a patient billing advocate can be valuable.

Does the GFE dispute process affect my credit?

While a dispute is pending through the federal patient-provider dispute resolution process, the provider is prohibited from sending the disputed amount to collections or taking adverse action against your credit. This protection applies during the review period. After the process concludes and a determination is made, the standard rules apply - if you owe the determined amount and do not pay it, the normal consequences of non-payment can follow.

What happens if my provider goes out of business or changes ownership before I receive care?

This is an edge case, but it matters. A GFE is issued by the specific provider entity that schedules your care. If that entity changes substantially - ownership transfer, merger, or closure - the GFE’s enforceability may be complicated. In practice, most billing continuity is maintained through transitions, but if you have a GFE from a provider that has undergone a significant change, confirm with the new entity that the estimate is still honored before your appointment.

Conclusion: The GFE Is a Tool - Use It

The Good Faith Estimate is not a perfect solution to medical billing opacity. It does not tell insured patients exactly what they will owe. It does not cover emergency care. It does not account for every unexpected provider who might become involved in your treatment. It is a disclosure requirement with real but bounded enforcement teeth.

What it is, unambiguously, is a legal right - and one that most patients never exercise. The majority of eligible patients do not request GFEs. Many providers do not issue them automatically. The result is that a protection Congress created specifically to give patients advance cost information is routinely unused, either because patients do not know about it or because they do not know how to ask.

Knowing about the GFE and requesting it changes your position in the medical billing system. It gives you information before care - when you still have choices. It gives you a baseline against which to measure your final bill. And it gives you access to a formal dispute process if that bill deviates significantly from what you were told.

That is worth something. In a system designed around information asymmetry, reducing that asymmetry - even partially, even imperfectly - is a meaningful form of financial protection.
