What is a surprise medical bill?
A surprise medical bill is a charge you didn't reasonably expect — usually because the provider was out-of-network when you had no practical way of knowing, or because the final bill came in far higher than the price you were quoted. Historically, surprise bills hit patients hardest after emergency room visits, air ambulance transports, and procedures where an out-of-network anesthesiologist or pathologist got involved during an otherwise in-network surgery.
In January 2022, the federal No Surprises Act took effect and changed the rules. It created two strong protections for patients:
- Balance-billing ban for insured patients — out-of-network providers in emergency situations and at in-network facilities can no longer bill you for more than your in-network cost-sharing. Disputes between the insurer and the provider are routed through the federal Independent Dispute Resolution (IDR) system — patients are kept out of it.
- Good Faith Estimates for self-pay patients — if you are uninsured or choose not to use your insurance, providers generally must give you a written Good Faith Estimate (GFE) when you request one or schedule care at least 3 business days in advance. Emergency, walk-in, and care scheduled only 1–2 business days ahead can be exceptions. A qualifying GFE and a charge at least $400 above one provider's estimate are two of several requirements for the federal Patient-Provider Dispute Resolution (PPDR) process.
PPDR and federal IDR are different processes. PPDR is the patient-facing process for qualifying uninsured or self-pay bills. Federal IDR resolves certain payment disputes between plans and providers; a patient does not initiate it. If insurance processed your claim, use the appeal instructions in your EOB or denial notice and contact the No Surprises Help Desk when protected out-of-network billing may be involved.

The No Surprises Act (Public Law 116-260, Division BB, Title I) is a federal statute, enforced jointly by HHS, the Department of Labor, and the Department of the Treasury. It applies nationwide as a floor rather than a ceiling. Where your state has a qualifying surprise-billing law, that state law generally governs the out-of-network rate, and the state may run its own patient-provider dispute process in place of the federal one. The federal rules fill the gap where a state has no such law — and they reach self-funded employer plans, which state insurance law generally cannot.
Right to a Good Faith Estimate
If you are uninsured or self-pay, providers generally must give you a written GFE when you request one or schedule care at least 3 business days in advance. Emergency care, walk-in appointments, and care scheduled only 1–2 business days ahead can be exceptions. If you believe a required estimate was not provided, use the No Surprises Help Desk complaint process; a complaint does not substitute for the actual GFE that PPDR requires.
When a bill may qualify for PPDR
CMS lists several core requirements: the care occurred on or after January 1, 2022; you did not have or did not use insurance and told the provider before care; you received the actual GFE at least 3 days before the scheduled appointment; you start the dispute within 120 calendar days of receiving the initial bill; and at least one provider or facility charged $400 or more above its estimate. Filing also requires a $25 non-refundable administrative fee, set by HHS and paid to the dispute-resolution entity. If the dispute is decided in your favor, that $25 is deducted from the amount you owe the provider. HHS can change the amount by guidance, so confirm it on cms.gov/nosurprises before you file. CMS and the SDR entity make the eligibility determination.
Right to emergency-care protection (insured)
In many covered emergency and in-network-facility situations, insured patients are protected from out-of-network balance billing and generally owe in-network cost-sharing. Exceptions, including some valid notice-and-consent situations, can apply. If the bill appears to violate these rules, contact the No Surprises Help Desk and review your plan's appeal instructions.
Right to a transparent disclosure notice
Providers and facilities must post a one-page disclosure summarizing No Surprises Act protections in specified public locations and online. A missing notice may support a complaint, but it does not replace the Good Faith Estimate or by itself establish PPDR eligibility.
Step-by-step: filing a PPDR dispute
Compare your final bill to your Good Faith Estimate
Pull out the actual GFE you received before care and line it up against the initial bill. Calculate the difference for each provider or facility. A charge that is at least $400 above that provider’s estimate meets the amount test, but it does not establish eligibility by itself; the other CMS requirements must also be met.
Confirm you were self-pay or uninsured for the service
PPDR applies only when you did not have or did not use insurance for this care and told the provider beforehand. If insurance processed the claim, PPDR does not apply. Review the EOB and denial notice for the plan-appeal route, and contact the No Surprises Help Desk if protected out-of-network billing may be involved. Federal IDR is handled between plans and providers.
Gather your documents
You will need the actual Good Faith Estimate, the initial bill, provider contact information, and the $25 non-refundable administrative fee HHS sets for the dispute process (confirm the current amount on cms.gov/nosurprises). Keep the bill envelope, portal timestamp, or email showing when the bill reached you, plus relevant communications. A statement that no GFE was provided is not a substitute for the estimate in PPDR.
File Form CMS-10780 within 120 days
Use the CMS patient-provider dispute form and submit a complete request with the required documents and fee. Your notice must be postmarked within 120 calendar days of the day you received the initial bill. If the deadline is close, contact the No Surprises Help Desk immediately and submit the complete filing as soon as possible.
Respond to the SDR within their deadlines
HHS assigns a certified Selected Dispute Resolution (SDR) entity after it receives your initiation notice. The rules set no fixed deadline for that assignment, so the wait varies. The SDR entity then contacts both sides — it gives the provider 10 business days to send its information. If your filing is incomplete or looks ineligible, you get an insufficiency notice and 21 calendar days to fix the problem (35 if you asked for an accessible format and did not get one in time), so a first "no" is often curable. Open every notice and answer by the date it gives you.
Receive the binding determination
The SDR issues a written determination after reviewing both sides. Review the decision and pay the amount it determines. The administrative fee is not refunded; if the dispute is decided in your favor, that amount is deducted from what you owe the provider. Other negotiation or state-law options may still be available.
What to include in your PPDR submission
The SDR reviews a limited record. What you submit is what gets considered — there is no in-person hearing. A strong submission includes:
- A one-page position statement stating the GFE amount, the billed amount, the overage, and why the excess charges are not supported by the estimate.
- The actual written Good Faith Estimate you received at least 3 days before the scheduled appointment. PPDR does not treat a statement that no estimate was provided as a substitute.
- The initial bill, with item and service details visible when available.
- Any pre-service paperwork you signed (consent forms, financial responsibility forms) — these sometimes contradict the GFE.
- A copy of the disclosure notice the provider was required to post. If they failed to, note it.
- Evidence of typical charges for the same service (Medicare reference rates, local fair-price databases) to support that the overage is not justified by standard market pricing.
- A clear, dated timeline of communications with the provider’s billing office.
Common mistakes to avoid
Missing the 120-day window
Your initiation notice must be postmarked within 120 calendar days of the day you received the initial bill. A placeholder is not a recognized way to preserve PPDR eligibility. If the deadline is close, contact the No Surprises Help Desk immediately and submit a complete filing as soon as possible.
Filing PPDR after insurance processed the claim
If insurance processed the claim, PPDR does not apply. An EOB does not mean that you can use federal IDR; that process is handled between plans and providers. Review the EOB and denial notice for your appeal route, and contact the No Surprises Help Desk if protected out-of-network billing may be involved.
Paying before filing
CMS says providers and facilities cannot move the disputed bill into collections or add new late fees while PPDR is underway. Keep copies of any payment agreement and ask the No Surprises Help Desk how the filing affects your specific bill before changing payments.
Submitting without the GFE
PPDR generally requires the actual Good Faith Estimate. If a provider should have supplied one but did not, use the No Surprises Help Desk complaint and action-plan tools. A written statement about the missing estimate does not replace it in a PPDR filing.
What to do if the SDR rules against you
An SDR determination is binding under federal law, but it is not the end of your options:
- Negotiate directly with the provider. Many providers offer charity care under §501(r) if you qualify based on income. Ask about hardship discounts, interest-free payment plans, or a one-time pay-in-full discount (often 20–40% off).
- File a state-level complaint. Many states have their own surprise-billing laws that overlap with the federal NSA. Your state insurance department or attorney general consumer protection office may take the case.
- Contact the No Surprises Help Desk. 1-800-985-3059 for complaints about providers that failed to give a GFE, failed to post disclosures, or violated the balance-billing ban. CMS can impose civil monetary penalties.
- Consult an attorney if the dollar amount is large. State-law unfair billing or deceptive-practices claims can sometimes succeed where federal PPDR did not.
