Good Faith Estimate Requirements Under the No Surprises Act

The Good Faith Estimate requirement comes from the No Surprises Act (Consolidated Appropriations Act, 2021) and its implementing regulation at 45 CFR 149.610, effective January 1, 2022. It applies to virtually every type of health care provider and facility — physicians, hospitals, ambulatory surgery centers, behavioral health providers, dentists, imaging centers, and more — when serving a specific population of patients.

Who must give a GFE: Any licensed or certified provider or facility that schedules an item or service for, or receives a GFE request from, an uninsured or self-pay individual.

Who is entitled to receive one:

• Uninsured individuals — patients with no health benefit plan, Medicare, Medicaid, CHIP, TRICARE, or other coverage.
• Self-pay individuals — patients who have coverage but are not seeking to have that coverage pay for the item or service (for example, a patient who elects to pay cash for a cosmetic procedure, a therapy session they keep off insurance, or a service their plan will not cover).

Who is NOT entitled to a GFE under this rule: Patients who are using their insurance for the service. For insured patients, a separate (later-phased) requirement called the Advanced Explanation of Benefits (AEOB) is intended to apply once the plan-facing GFE provisions are enforced — but the convening-provider GFE obligation described here governs the uninsured and self-pay population today.

In our compliance reviews we consistently find practices that built a GFE workflow for scheduling but never trained front-desk staff to recognize the self-pay trigger — an insured patient who says 'don't bill my insurance, I'll pay cash' is a self-pay individual and is owed a GFE just like an uninsured patient. Missing that trigger is the most common GFE gap we see. For the broader patient-financial workflow this lives inside, see our patient billing and collections services.

The single most-failed part of the rule is timing. The deadline depends on how far in advance the service is scheduled — measured in business days, not calendar days — and there is a separate rule for on-request estimates. The table below is the exact compliance clock.

Reading the clock correctly:

• The windows are stated as a minimum lead time (the patient scheduled the service that far ahead) paired with a response deadline (how fast you must deliver after scheduling). A patient who books 4 business days out triggers the '≥3 business days' row, so the GFE is due within 1 business day of that booking.
• A patient request resets the clock to 3 business days from the request, regardless of whether anything is scheduled. If a patient calls to ask 'what will this cost if I pay cash,' you owe a written GFE within 3 business days.
• Material changes to expected services, scheduled date, or charges require a new GFE no later than 1 business day before the service date.

Because the windows are short, the durable fix is to generate the GFE as a byproduct of scheduling itself — at the moment a self-pay or uninsured appointment is booked — rather than as a separate manual task a staffer remembers (or forgets) to do later.

A compliant GFE is not a ballpark price quote — 45 CFR 149.610(c) specifies the data elements it must contain. Use this as a build-and-audit checklist; an estimate missing any required element is non-compliant even if the dollar figure is right.

Disclaimer language matters. The dispute-rights disclaimer (element 9) is what informs the patient about the $400 PPDR threshold — omitting it is both a compliance failure and a practical one, because it leaves your patient unaware of (and unprepared for) the dispute pathway. CMS publishes model disclaimer language and a standard GFE template that practices can adopt to satisfy these requirements.

The estimate must be furnished in writing (paper or electronic, per the patient's requested method), in a manner the patient can understand, and a copy must be retained for at least 6 years and made available on request — the same retention discipline you would apply to any patient-financial record.

When a single episode of care involves more than one provider or facility, the rule assigns roles so the patient receives one coordinated estimate rather than a pile of partial ones. Getting these definitions right is the difference between a complete GFE and a non-compliant one.

Convening provider / convening facility. The provider or facility that receives the initial request for the item or service, or that is responsible for scheduling the primary item or service. The convening party owns the estimate: it must furnish the GFE to the patient and, when other providers are involved, incorporate their expected charges.

Co-provider / co-facility. A provider or facility (other than the convening one) that is expected to furnish items or services in conjunction with the primary item or service — for example, the anesthesiologist, pathologist, or facility associated with a scheduled surgery. Co-providers must supply their GFE information to the convening provider upon request so it can be folded into the single estimate the patient receives.

How the assembly works in practice:

• The convening provider identifies the co-providers reasonably expected to be involved.
• The convening provider requests each co-provider's GFE information (their expected items/services, codes, and charges).
• Each co-provider returns that information so it can be combined.
• The convening provider assembles and delivers the single, complete GFE to the patient within the applicable timing window.

Enforcement-discretion note: CMS has exercised enforcement discretion on the requirement to include co-provider/co-facility charges in the convening provider's estimate — meaning the obligation to aggregate other providers' estimates has not been actively enforced in the same way as the convening provider's own-charges obligation. That discretion can change; the durable position is to estimate your own expected charges accurately and completely on every GFE, and to coordinate co-provider amounts where you reasonably can. Treat the convening-provider self-estimate as the non-negotiable baseline and co-provider aggregation as the best-practice target.

The GFE has teeth because of the Patient-Provider Dispute Resolution (PPDR) process. If a patient is billed substantially more than their Good Faith Estimate, they can challenge the bill through a federal third-party dispute-resolution entity — and 'substantially more' has a precise definition.

The $400 threshold. A patient may initiate PPDR when the total billed charges (from a single provider or facility) are at least $400 more than the total expected charges listed in that provider's or facility's Good Faith Estimate. The threshold is measured per convening provider/co-provider — each party's billed total is compared against the GFE charges attributed to that party.

How PPDR works (patient side):

1. The patient must initiate the dispute within 120 calendar days of receiving the bill.
2. A selected dispute resolution (SDR) entity certified by HHS reviews the GFE, the actual bill, and supporting documentation.
3. There is a small administrative fee to initiate (waived for patients who qualify as low-income).

How the SDR entity decides:

Why this matters operationally: an under-scoped GFE is not a way to look cheaper — it is a way to lose the difference in dispute. If you estimate $1,200 and bill $2,000 for the same scope, the patient can hold you to roughly the $1,200 GFE figure through PPDR. The compliant and financially sound move is the same move: estimate accurately, document any unforeseen services that drove a higher bill, and reissue a GFE when scope changes materially before the date of service.

Below is a model itemized Good Faith Estimate showing the required elements assembled into a single document. The dollar figures are illustrative only — your actual charges, codes, and providers will differ. Use this as a structural template, not a price list.

GOOD FAITH ESTIMATE OF EXPECTED CHARGES

Patient: Jane Q. Sample | DOB: 04/12/1986 | Date of Estimate: June 17, 2026

Primary service: Diagnostic upper endoscopy (outpatient), scheduled July 7, 2026

Convening provider/facility: Example GI Center | NPI: 1234567890 | TIN: 12-3456789 | 100 Main St, Anytown

Items the convening provider expects may require separate scheduling: Pre-procedure consultation and any follow-up visit are scheduled separately; a separate GFE will be furnished on scheduling or request.

Required disclaimers (must appear on the estimate):

• This Good Faith Estimate shows the costs of items and services that are reasonably expected for your health care needs. The estimate is based on information known at the time it was created.
• This estimate does not include any unknown or unexpected costs that may arise during treatment (for example, complications or additional services).
• If you are billed $400 or more above this Good Faith Estimate, you may be able to dispute the bill through the Patient-Provider Dispute Resolution process. You must start the dispute within 120 calendar days of the date on your bill.
• This Good Faith Estimate is not a contract and does not require you to obtain the listed items or services.

Keep a copy of this Good Faith Estimate in a safe place. You may need it if you are billed more than the estimate. CMS provides a downloadable standard GFE form and model disclaimer language at the No Surprises Act help pages on cms.gov — adopting the model template is the fastest way to satisfy the format and disclaimer requirements.

Because the timing windows are measured in business days and the dispute risk is real money, the GFE has to be an operational reflex, not a memory test. Here is the workflow we recommend practices implement.

1. Flag uninsured and self-pay status at scheduling. Add a hard stop in scheduling and registration that asks, for every appointment, whether the patient is uninsured or electing self-pay (not billing insurance for this service). This single field is the trigger that the entire requirement hangs on — and it is the most commonly missed step.

2. Auto-generate the GFE from the encounter's expected codes. Map the scheduled service to its expected CPT/HCPCS, ICD-10, and standard charges so the estimate populates from your charge master rather than being keyed by hand. This is the same data discipline that drives accurate charge entry and clean claims downstream.

3. Apply the correct timing window automatically. Calendar the deadline the moment the appointment is booked: 1 business day (scheduled ≥3 business days out) or 3 business days (scheduled ≥10 business days out or on request). A scheduling rule that calculates and tracks the due date prevents the most common compliance miss.

4. Deliver in writing, in the patient's chosen format, and document delivery. Paper or electronic per the patient's request, in plain language, with proof of delivery logged. Retain the GFE for at least 6 years.

5. Reissue on material change. If the scope, scheduled date, or expected charges change materially, issue a new GFE no later than 1 business day before the service. This is also your best defense against a future PPDR challenge.

6. Coordinate co-provider amounts where practical. For multi-provider episodes (surgery, endoscopy, imaging with pathology), request co-provider GFE information and fold it into the convening estimate — keeping your own-charges estimate accurate as the non-negotiable baseline.

A practice that operationalizes these six steps treats the GFE as a scheduling output rather than a compliance chore, which is what keeps both the regulator and the patient satisfied. This compliance posture sits alongside the broader price-transparency landscape — for the hospital-side rules, see the price transparency rule glossary entry, and for the full surprise-billing framework, the No Surprises Act glossary entry.

The GFE rule is procedurally simple but operationally easy to botch. These are the failure patterns we see most often in compliance reviews, and the denial-style consequences they create on the patient-financial side.

1. Treating only the uninsured as in scope. The most frequent error: building a workflow that fires for patients with no insurance but ignoring self-pay patients who have coverage they are choosing not to use. Both populations are entitled to a GFE.

2. Missing the business-day clock. Counting calendar days instead of business days, or starting the clock from the date of service instead of the date of scheduling/request. The deadline runs from when the appointment is booked (or the request is made), not from the visit.

3. Under-scoping the estimate to look affordable. Leaving out expected ancillaries (anesthesia, pathology, facility fees) makes the GFE look cheaper but exposes the practice to PPDR — the patient can hold you to the under-scoped figure when the real bill lands.

4. Omitting required codes or disclaimers. A 'price quote' without CPT/HCPCS codes, diagnosis codes, NPI/TIN, or the dispute-rights disclaimer is not a compliant GFE even if the total is accurate.

5. No reissue after a scope change. When the planned procedure changes but the original GFE is never updated, the practice loses both compliance and its strongest PPDR defense.

6. Not retaining the GFE. The estimate must be kept for at least 6 years and producible on request; practices that generate but do not archive GFEs cannot defend a dispute.

The downstream connection to denials and patient AR. A self-pay encounter that is mishandled at the GFE stage tends to resurface as a patient-balance dispute or a write-off later — the patient-financial analog of a clean-claim failure. Where insurance is involved and a coverage question arises (for example, the patient assumed they were self-pay but later wants insurance to pay), eligibility and coordination issues can surface as denials such as PR-1, PR-2, and PR-3 patient-responsibility adjustments. Building the GFE correctly at the front end is the same prevention philosophy that keeps the back end clean: get the data and the disclosure right before the service, and you avoid the expensive cleanup after.
