Good Faith Estimate: Your Rights as an Uninsured or Self-Pay Patient

What a Good Faith Estimate is

A Good Faith Estimate (GFE) is a written, itemized estimate of the total expected charges for a medical item or service you have scheduled or requested, plus anything reasonably expected to go with it. You get it before you receive care.

It was created by the federal No Surprises Act and has been required since January 1, 2022 (45 CFR 149.610). The point is to let you see costs in advance and, if the final bill lands much higher, give you a formal way to challenge it.

It applies to almost all providers and facilities, not just hospitals. That includes doctors, clinics, imaging centers, surgery centers, dentists, and mental health providers.

Who gets one

Two groups are legally entitled to a GFE:

• Uninsured patients.
• Self-pay patients, meaning you have insurance but choose not to file a claim for this item or service and are paying out of pocket instead.
• Providers must also post notices and tell you about your right to a GFE.
• Important as of 2026: the insured version, called the Advanced Explanation of Benefits (AEOB), for people running care through their coverage is still delayed and NOT in effect. Federal agencies said they expected to propose an AEOB rule around March 2026. So for now, if you plan to use your insurance, you generally cannot yet demand a federal AEOB. The GFE right is for uninsured and self-pay only.

When you should get it (timing)

The deadlines depend on how far ahead you schedule or when you ask:

• Scheduled at least 3 business days ahead: GFE no later than 1 business day after scheduling.
• Scheduled at least 10 business days ahead: GFE no later than 3 business days after scheduling.
• Just shopping around (no appointment yet): GFE no later than 3 business days after you request it.
• If the plan changes and a new estimate is needed: an updated GFE no later than 1 business day before the service.
• Care scheduled fewer than 3 business days out: a GFE is NOT required, and short-notice estimates are not eligible for the dispute process.
• It must be in writing (paper or electronic, your choice) and in a form you can keep.

What must be on it

A proper GFE is detailed. It should include:

• Your name and date of birth.
• A clear description of the main item or service (and the scheduled date, if any).
• An itemized list of the items and services expected, grouped by each provider or facility.
• Applicable diagnosis codes, expected service codes (such as CPT/HCPCS), and expected charges for each item.
• Each provider or facility’s name, National Provider Identifier (NPI), Tax Identification Number (TIN), and the location where care happens.
• A note about items needing separate scheduling, and that separate GFEs will be issued for those.
• Disclaimers that it is only an estimate, that actual charges may differ, that it is not a contract, and that you can use the dispute process if billed at least $400 over the estimate.

What it does NOT cover

The GFE is powerful but it has clear limits:

• Emergency care. The GFE is for scheduled or requested (planned) care only.
• Insured patients using their coverage. The insured AEOB is not yet in effect as of 2026.
• Care scheduled fewer than 3 business days out. No GFE is required and it is not dispute-eligible.
• Truly unforeseen or newly recommended services discovered during care that were not reasonably expected at estimate time.
• It is an estimate, not a guaranteed price or a contract. Actual charges can legitimately differ, and the GFE does not by itself cap your bill unless you win a dispute.
• It does not resolve insurance cost-sharing, network status, or balance-billing questions for people using insurance. Those are governed by other parts of the No Surprises Act.

The real-world limitations to know

Enforcement is uneven, and there is one gap worth understanding. The rule that a ’convening provider’ bundle a single comprehensive GFE including expected charges from co-providers and co-facilities (for example, the anesthesiologist and pathologist tied to a surgery) is still under HHS enforcement discretion as of 2026. HHS paused it for 2022 and, in a December 2, 2022 FAQ, extended that non-enforcement indefinitely pending future rulemaking.

In practice, your GFE often reflects only the scheduling provider’s own charges, so separate bills from other providers can arrive without ever having been estimated. One nuance: if a co-provider gives you its own separate GFE, you can still dispute that provider’s bill under the $400 rule. The practical problem is that many co-providers simply never issue one.

Beyond that, many providers still do not offer GFEs proactively, estimates can be vague or omit likely add-ons, and awareness among front-desk staff is often low. The right is real and worth using. It protects you best when your care comes from a single provider or facility that estimates its own charges accurately.

How CareRoute Bill Defense can help

If you already have a bill that came in higher than your estimate, you do not have to fight it alone. CareRoute Bill Defense can review your bill against the Good Faith Estimate, confirm whether the $400 rule applies, and run the Patient-Provider Dispute Resolution process for you.

It is $0 upfront, and there is no fee unless we save you money. Keep your GFE and your itemized bill handy, since those are the two documents that make the strongest case.

How to request a Good Faith Estimate

1. 1Tell the provider, facility, or scheduler that you are uninsured, or that you will self-pay and are not filing an insurance claim for this care.
2. 2Ask directly for a ’Good Faith Estimate’ under the No Surprises Act. You can request one even before scheduling, just to compare prices.
3. 3Do it as early as possible. Requesting 3 to 10 business days ahead gives you the fullest rights and the most useful lead time.
4. 4Ask for it in writing (paper or electronic), keep a dated copy, and note the date you requested it.
5. 5If a provider refuses, misses the deadline, or says they do not do estimates, remind them it is a federal requirement (45 CFR 149.610). You can file a complaint with CMS at 1-800-985-3059 or at cms.gov/nosurprises.
6. 6File the GFE with your records so you can compare it against the final bill later.

Bill $400+ over your estimate? How to dispute it

1. 1Confirm you are eligible: you were uninsured or self-pay, you received a GFE, the bill is dated within the last 120 calendar days, and at least one provider or facility billed you at least $400 over its own estimate (the $400 is measured per provider, not for the whole visit combined).
2. 2File within 120 calendar days of the date on the first bill for the disputed item or service. Submit online at cms.gov/nosurprises or mail the dispute form.
3. 3Pay the $25 non-refundable administrative fee to start the dispute. A fee waiver may be available if paying it would cause financial hardship.
4. 4CMS assigns an independent, third-party reviewer (a Selected Dispute Resolution, or SDR, entity) to review your GFE, your bill, and supporting information.
5. 5While the dispute is pending, the provider cannot send the bill to collections (or must pause collections already underway), cannot charge late fees on the disputed amount, and cannot retaliate. You and the provider can keep negotiating.
6. 6The SDR entity issues a binding decision on what you owe. If the billed items match the GFE, you generally owe the billed amount. If they exceed it, the amount is limited (typically to the estimate, or a capped amount for new items). The provider cannot bill you more than the SDR-determined amount for the disputed items.
7. 7If you settle with the provider for less before the decision, tell the SDR entity. When an SDR determination comes in lower than the billed charge, your total owed is reduced by the full $25 fee. If you settle first, the provider reduces the settlement by at least half the fee.
