What Is a Good Faith Estimate
A Good Faith Estimate (GFE) is a written breakdown of expected costs for scheduled medical services that providers must give uninsured or self-pay patients at least three business days before treatment. Established under the No Surprises Act (effective January 1, 2022), this federal requirement applies to non-emergency, scheduled procedures and services where you're paying out-of-pocket rather than billing insurance.
The estimate must include itemized charges for facility fees, provider fees, and supplies specific to your planned procedure. It's a snapshot of what you should expect to pay, not a binding invoice, though providers are legally required to limit charges to within 15% of the estimate total (or $250, whichever is greater).
When You Receive One
Providers must issue a GFE when you call or visit to schedule a non-emergency service and inform them you're paying without insurance. This typically happens during pre-authorization calls or initial consultations. Some states like New Hampshire and Florida have additional state-level requirements that exceed federal minimums. If your procedure requires prior authorization from an insurer, the provider often obtains that information before calculating your estimate.
You have the right to request a GFE even if the provider doesn't proactively offer one. Ask specifically for an itemized breakdown rather than a single number, since this helps you identify where costs are concentrated and spot billing errors later.
How to Use It in Claims Disputes
- Challenge inflated bills: If you receive a final bill exceeding the GFE by more than 15% or $250, you can file a complaint with your state's insurance commissioner or the Centers for Medicare and Medicaid Services (CMS). Document the original GFE and final bill together.
- Support appeals: When fighting a denied claim on grounds of medical necessity, an accurate GFE showing the procedure was planned and disclosed upfront strengthens your internal appeal. Insurers sometimes deny claims after seeing unexpected costs; the GFE proves you and the provider acted transparently.
- Verify patient responsibility: Cross-reference your GFE against your Explanation of Benefits (EOB) once insurance processes the claim. If your patient responsibility differs significantly from what was estimated, request a detailed EOB review before paying.
- Track for external appeals: If you proceed to external appeal (independent review), include the GFE in your appeal package to show the procedure was medically necessary, appropriately priced, and disclosed beforehand.
What a GFE Does Not Cover
A GFE only applies to scheduled, non-emergency services. Emergency care, urgent same-day procedures, and follow-up visits are exempt. If you're insured, you won't receive a GFE; instead, you'll get cost estimates through your insurer's pre-authorization process. The estimate also doesn't guarantee insurance coverage or address whether your plan considers the procedure medically necessary.
If a provider later discovers additional work is needed during your procedure (like complications discovered during surgery), they can bill beyond the estimate, though they must notify you as soon as practicable and provide an updated estimate.
Common Questions
- Can a provider refuse to give me a GFE? No. Federal law requires them to provide one for scheduled, non-emergency services when you're self-pay. If they refuse, file a complaint with CMS or your state insurance commissioner. This violation can strengthen your case if you later dispute overcharges.
- What if my GFE was missing items that appeared on my final bill? Request an itemized bill and compare line-by-line. Bills that include charges not in the GFE may violate the 15% variance rule. Send a written dispute to the provider's billing department and, if unresolved, escalate to your state's insurance commissioner.
- Does a GFE protect me if my insurance denies the claim for medical necessity? No. A GFE only addresses cost transparency, not medical necessity determinations. If your claim is denied, the GFE helps you argue the procedure was appropriately disclosed and priced, but you'll still need clinical evidence (medical records, provider notes) to challenge a medical necessity denial through internal or external appeal.
