Use when an out-of-network provider has billed a service that is governed by the federal No Surprises Act's balance-billing protections (emergency services under 42 U.S.C. § 300gg-111, out-of-network ancillary services at an in-network facility under § 300gg-111(b), or air-ambulance services under § 300gg-112), the patient's plan has paid an out-of-network allowed amount that the provider is contesting, and the provider is balance-billing the patient for the spread.
The patient's own option here is to dispute the provider directly under templates/letter_no_surprises_violation.md. The parallel, and often faster, option is to ask the patient's plan to initiate the federal Independent Dispute Resolution (IDR) process against the provider. IDR is a binding arbitration between the plan and the provider over the amount; the patient is held to in-network cost-sharing during and after, with the plan and provider fighting over the spread.
Patients cannot initiate IDR directly (that right belongs to the plan and the provider after a 30-business-day open-negotiation period). But patients can formally request, and document the plan's response, which becomes useful evidence if the plan later fails to protect the patient from balance billing.

Provider in dispute: [PROVIDER NAME] (NPI: [PROVIDER NPI])
Date(s) of service: [DATE OF SERVICE]
Claim number(s): [CLAIM NUMBER(S)]
Qualifying basis: [emergency services / out-of-network ancillary at in-network facility / air-ambulance]
To Member Services / Plan Administrator:
I am a participant in the plan referenced above. The provider listed has billed me for services that are subject to the federal No Surprises Act's balance-billing protections. The provider's billed amount materially exceeds the plan's allowed amount as adjudicated on the EOB. I am writing to:
(a) formally request that the plan initiate, or join in initiating, the federal Independent Dispute Resolution process against the provider for the disputed claim(s);
(b) confirm that, irrespective of the outcome of IDR, my cost-sharing for these services is fixed at the in-network cost-sharing amount; and
(c) place the plan on written notice that any failure to protect me from balance billing during and after the IDR process is itself a violation of the plan's obligations under 42 U.S.C. § 300gg-111.
I. Qualifying basis
The services on the claim(s) referenced above qualify for No Surprises Act balance-billing protection because:
[The drafter renders whichever applies.]
[BASIS A, Emergency services]
The services were emergency services within the meaning of 42 U.S.C. § 300gg-111(a)(3)(C)(i). I received care at the emergency department of [FACILITY], an [in-network / out-of-network] emergency department, on [DATE]. Under § 300gg-111(a)(1), my cost-sharing for these services must be calculated as if the services were provided by an in-network provider; the provider is prohibited from balance-billing me for any amount above in-network cost-sharing.
[BASIS B, Out-of-network ancillary at in-network facility]
The services were furnished by an out-of-network provider at [FACILITY], an in-network facility on [DATE]. The provider type is one of the categories covered by § 300gg-111(b)(1)(B) (anesthesiology, emergency medicine, pathology, radiology, neonatology, laboratory services, or assistant-surgery services). I did not receive prior written notice of out-of-network status, and the notice-and-consent exception under § 300gg-111(d) does not apply because [the service category is one of the categories for which consent is statutorily unavailable / no compliant notice was provided]. The provider is therefore prohibited from balance-billing me for any amount above in-network cost-sharing.
[BASIS C, Air ambulance]
The services were air-ambulance services within the meaning of 42 U.S.C. § 300gg-112. The patient's cost-sharing is fixed at in-network cost-sharing; the provider is prohibited from balance-billing me.
II. Disputed claim detail
For the claim(s) referenced above:
- Provider billed amount: $[BILLED]
- Plan allowed amount per EOB: $[ALLOWED]
- Plan paid amount per EOB: $[PAID]
- My in-network cost-sharing per EOB: $[COST SHARE]
- Provider is balance-billing me for: $[BALANCE BILLED]
The $[BALANCE BILLED] portion of the provider's bill is the spread the IDR process is designed to resolve. That dispute is properly between the plan and the provider, not between me and the provider.
III. Open-negotiation status (45 CFR § 149.410)
Under § 149.410, the plan and the provider must engage in a 30-business-day open-negotiation period before either party may initiate IDR. If open negotiation has been initiated, please confirm:
1. The date open negotiation began;
2. The plan's offered rate during open negotiation;
3. The provider's offered rate during open negotiation;
4. The current status (in-process / concluded without agreement / agreement reached).
If open negotiation has not been initiated, please initiate it within ten (10) business days of receipt of this letter and confirm in writing.
IV. Request to initiate IDR (45 CFR § 149.510)
If open negotiation does not yield an agreement, please initiate the federal IDR process by submitting a Notice of IDR Initiation to the federal IDR portal within the statutory window (the 4-business-day window following the end of open negotiation under § 149.510(b)(1)). Please copy me on the Notice of IDR Initiation when filed, along with the certified IDR entity selected.
V. Protection from balance billing during and after IDR
Irrespective of how the IDR is resolved:
1. My cost-sharing remains fixed at the in-network cost-sharing amount per § 300gg-111. The IDR resolves only the plan-vs-provider allowed amount, not the patient's cost-sharing.
2. The provider is statutorily prohibited from billing me for any amount above the in-network cost-sharing. Any communication from the provider asserting a balance above that amount is, on its face, a violation of § 300gg-111.
3. The plan is obligated under the federal rule and under the plan's ERISA fiduciary duties (29 U.S.C. § 1104) to ensure I am not balance-billed for these services. Please confirm in writing what steps the plan will take if the provider persists in balance-billing me, including but not limited to direct communication with the provider, complaint to the federal No Surprises Help Desk, and reporting to the state insurance department of the provider's domicile.
VI. ERISA § 503 / 29 U.S.C. § 1133 claims-procedure rights
To the extent the plan's adjudication of the claim is itself in dispute (e.g., if the plan's allowed amount is below the QPA the plan should have used, or below what a reasonable IDR result would produce), I separately request:
1. A full and fair review of the claim under ERISA § 503;
2. A complete copy of all documents, records, and other information relevant to the claim under 29 CFR § 2560.503-1(h)(2)(iii);
3. The qualifying payment amount (QPA) used and the methodology by which it was determined under 45 CFR § 149.140.
VII. Response window
Please respond within thirty (30) calendar days of the date of this letter, confirming:
(a) Whether the plan agrees that the claim(s) above qualify for No Surprises Act protection;
(b) Whether open negotiation has been initiated and its current status;
(c) Whether the plan will initiate IDR if open negotiation does not resolve the dispute;
(d) What the plan will do to protect me from balance billing during the process.
VIII. Reservation of rights
If the plan declines to initiate IDR or fails to protect me from balance billing, I reserve the right to:
- File a complaint with the federal No Surprises Help Desk (cms.gov/nosurprises);
- File a complaint with the [STATE] Department of Insurance, Consumer Services;
- File a complaint with the U.S. Department of Labor, Employee Benefits Security Administration, asserting the plan's breach of NSA and ERISA fiduciary duty;
- File a civil action under ERISA § 502(a)(1)(B) to recover plan benefits and enforce my rights under the plan and the No Surprises Act.
Please direct your response to the address above.
Sincerely,

- The drafter selects the qualifying basis (A, B, or C) from the bill's
findingscolumn ontracker.csvand from the EOB'snetwork_statusand place-of-service codes. If none of the three bases clearly applies, this template is the wrong tool, the patient should use the direct provider dispute vialetter_no_surprises_violation.mdinstead. - "Out-of-network ancillary at in-network facility" requires the specific provider type to be one of the protected categories. The drafter should confirm the provider type from the bill's
provider_typefield (anesthesiology, emergency_medicine, pathology, radiology). If the type is something else (e.g., orthopedist), Basis B does not apply. - The CC list is important. Sending a courtesy copy to the provider does two useful things: it puts the provider on notice that the patient understands NSA protections (often enough to stop balance-billing on its own), and it makes the provider's continued balance-billing actionable as a "knowing" violation rather than an oversight.
The drafter confirms:
- The EOB clearly shows the plan adjudicated the claim with in-network cost-sharing applied per NSA. If the EOB shows out-of-network cost-sharing being passed to the patient, the underlying issue is the plan's adjudication, not the provider's bill, handle via ERISA appeal first (
letter_insurance_appeal_erisa.md). - The provider has actually balance-billed (i.e., sent a statement showing patient owes more than EOB cost-sharing). If only a single statement at the EOB cost-sharing amount has arrived, there's no balance-billing yet.
- The 30-business-day open-negotiation clock is not yet exhausted on the plan's side. If open negotiation has already closed without an IDR filing, that itself is the violation, note it in the letter and request the plan explain why IDR was not filed.
- File a complaint with the federal No Surprises Help Desk at cms.gov/nosurprises or 1-800-985-3059. The federal complaint creates a CMS-side record and triggers federal-side investigation independent of the plan's response.
- File a parallel state-DOI complaint via
templates/complaint_state_doi.md, Category B (NSA balance-billing). - If the provider continues to send statements while this letter is pending, do not pay; the federal rule fixes the patient's cost-sharing.
- 30 days from postmark: the plan should have responded with the IDR status and protection plan. If silence, escalate to DOL EBSA at 1-866-444-3272.
- If the plan refuses to initiate IDR: that refusal itself is reportable to the federal No Surprises Help Desk and may be the basis of an ERISA fiduciary-duty claim.
- If the IDR is initiated and the patient is asked to provide information: respond promptly. The IDR record is the plan-vs-provider record, but the patient's documentation (EOB, statements, prior correspondence) often appears in the file.
- IDR is a plan-vs-provider process; the patient does not file directly. The patient's direct route under the NSA is the No Surprises Help Desk complaint and the direct provider dispute. This letter is a tool for prompting the plan, not a substitute for the patient's own complaint track.
- For self-pay / uninsured patients, the analogous process is Patient-Provider Dispute Resolution (
templates/letter_ppdr_initiate.md), not IDR.
