Good Faith Estimate Dispute Letter — Annotated Example
If you're uninsured or self-pay and received a written Good Faith Estimate, the federal No Surprises Act may let you dispute a final bill that exceeds the estimate by a significant margin. This letter raises that discrepancy and asks the provider to reconcile the bill.
Your real packet includes a letter like this one anda matching phone script — so you're ready whether you write or call.
Sample scenario
- Provider
- Mountain View Surgical Center
- Bill
- $5,400 final bill (Good Faith Estimate was $2,000)
- Situation
- A self-pay patient received a written Good Faith Estimate of about $2,000 but was later billed $5,400 — roughly $3,400 more than estimated.
Recommended approach
- Raise the discrepancy in writing and ask the provider to reconcile it (this letter).
- Keep your Good Faith Estimate and the final bill together as documentation.
- Ask the provider about the patient-provider dispute resolution process if it isn't resolved directly.
What it can help with
- The bill brought in line with the estimate, or the difference explained
- A documented record for a formal dispute if needed
- Leverage rooted in a federal consumer protection

[Date] Mountain View Surgical Center Attn: Patient Financial Services [Provider Address] Re: Good Faith Estimate Discrepancy Account Number: [Your Account Number] Patient Name: [Your Name] Date(s) of Service: [Service Date] Good Faith Estimate Dated: [Estimate Date] — Estimated Amount: $2,000.00 Final Billed Amount: $5,400.00 To Whom It May Concern: As a self-pay patient, I received a written Good Faith Estimate dated [Estimate Date] for approximately $2,000.00 in connection with the services referenced above. The final bill I received is $5,400.00 — about $3,400.00 more than the estimate. I understand that, under the federal No Surprises Act, self-pay and uninsured patients who receive a Good Faith Estimate may be able to dispute a final bill that exceeds that estimate by $400 or more, and that a patient-provider dispute resolution process may be available in those circumstances. Before pursuing that process, I would like to give us the opportunity to resolve this directly. I am requesting that you review this account and either adjust the final bill so that it reasonably aligns with the Good Faith Estimate, or provide a written explanation of the specific additional services that account for the difference. Please send your response, along with any corrected statement, to the contact information below. Thank you for your prompt attention to this matter. Sincerely, [Your Name] [Your Contact Information]
Why this letter works
What each part is doing and why it matters.
Estimate vs. final, side by side
Putting both figures and the estimate date up top makes the gap impossible to overlook and frames the whole letter.
Carefully hedged law reference
Note the language: patients "may be able to dispute" a bill exceeding the estimate "by $400 or more." It invokes the No Surprises Act accurately without claiming an automatic outcome.
Offering to resolve directly first
Signaling you'll use the formal dispute process only if needed is both reasonable and quietly persuasive.
Two acceptable outcomes
Asking the provider to either adjust the bill or justify the difference gives them a fair path while keeping pressure on.
What to say if you call instead
Your packet includes a full phone script. Here's a preview of the key pieces.
Call goal
Ask why the final bill is much higher than the written estimate you received and request an explanation.
Opening
“Hi, my name is [Your Name]. I'm calling about a bill for services on [Service Date]. Before my appointment I received a Good Faith Estimate, and the final bill is quite a bit higher.”
Your ask
“Can you explain the specific charges that caused the difference, and tell me what the process is to address it?”
If they say…
They say:
"Estimates are never guaranteed."
You can say:
"I understand, but I'd like to know what specific items caused the difference. Can you connect me with someone in billing who can walk me through the charges?"
The full script in your packet also includes a call preparation checklist, a documentation form to fill in during the call, and a follow-up email template.
Good for
- Self-pay or uninsured patients
- A final bill well above a written Good Faith Estimate
- Scheduled (non-emergency) services you were quoted for
Not the right fit
- You have insurance that processed the claim — an Insurance Appeal may fit better
- You never received a Good Faith Estimate — use Itemized or Billing Error instead
- The bill matches the estimate but is unaffordable — use Hardship or a Payment Plan

Whether any particular law or program applies depends on your specific situation. Your packet will use the details from your own bill.
