If your private health insurer denied an emergency-care claim, appeal the coverage or payment decision through the plan’s review process. If an out-of-network provider also sent you a large bill, separately check whether the federal No Surprises Act limits what you can be charged. These are different problems, and you may need to pursue both routes. Start with the denial notice or explanation of benefits (EOB): it identifies the reason for the decision and should give the applicable deadline, filing address, and next steps.
First identify what you are challenging
An EOB explains how the plan processed a claim; it is not itself a bill. Compare it with the provider’s bill and identify whether the problem is a denied claim, an out-of-network balance bill, or both. A bill from an out-of-network provider alone does not prove that the plan wrongly denied coverage or that the bill violates federal protections.

- Coverage or payment denial: The plan says it will not cover a service, or will pay less than you believe the plan requires. Challenge this through an internal appeal and, where eligible, external review.
- Unexpected out-of-network bill: The provider is seeking payment beyond your plan’s in-network cost sharing. Check whether No Surprises Act protections apply and consider contacting the federal Help Desk.
- Both: Keep the insurance appeal moving while you investigate the bill. A complaint about billing protections does not replace an appeal of the plan’s coverage decision.
On the EOB and denial notice, note the claim number, date of service, date you received the decision, stated reason, appeal recipient, and deadline. Keep the full notice, not just a portal summary. Your plan documents, including a job-based plan’s Summary Plan Description, can clarify the specific procedure.
Could the No Surprises Act limit the bill?
The federal No Surprises Act took effect January 1, 2022. CMS says it protects many people with employer coverage and individual-market coverage from certain unexpected out-of-network bills. The protections are about what a provider may bill you; they do not automatically require your plan to cover every claim. CMS’s “Medical bill rights” page and No Surprises Act guidance explain the covered situations.
Emergency services
If your plan covers emergency care, the Act generally limits your cost sharing for covered emergency services to the in-network amount, even when the hospital, treating providers, or air ambulance provider is out of network. The law also generally bars balance billing for those services. Check your plan’s terms: some plans do not cover emergency care. Ground ambulance services are generally outside the federal Act’s billing protections, although state law may provide protections.
Care after stabilization and care at an in-network facility
Protections generally continue for post-stabilization care, but in certain circumstances a provider may seek a notice-and-consent waiver. Providers cannot ask you to waive protections for emergency services in an emergency room, and certain specialists and emergency-related services cannot use those waivers. The Act also protects some planned out-of-network care connected with an in-network hospital, hospital outpatient department, or ambulatory surgical center. It does not generally extend those protections to other settings such as a standalone doctor’s office or an out-of-network facility.
If a bill appears inconsistent with these protections, contact the No Surprises Help Desk at 1-800-985-3059. Have the bill, EOB, date of service, and facility details available. If your insurer separately denied payment, submit the plan appeal as well.
File an internal appeal with the plan
Use the appeal instructions in the denial notice, including the specified form, destination, and deadline. HealthCare.gov’s general consumer guidance describes a 180-day window after receiving a denial notice, while also listing 30 days for an appeal involving a service not yet received and 60 days for an appeal involving a service already received. These are procedural timeframes, not a reason to assume one deadline applies to every claim. The notice, plan terms, and applicable rules determine your deadline; file promptly and ask the plan to confirm it if unclear.
- Address the stated reason. Identify the service and claim number, then explain why you believe the plan’s stated basis is wrong. For an emergency-care dispute, describe the circumstances that made the care an emergency. For a medical-necessity dispute, ask the treating clinician to address the plan’s rationale.
- Include relevant supporting records. Depending on the issue, that may mean the denial and EOB, itemized bill, relevant medical records, a clinician’s letter, or records clarifying the facility or provider’s network status. These are useful examples, not a complete mandatory checklist.
- Send it to the correct recipient and retain proof. HealthCare.gov says you may use the insurer’s required form or write to the insurer with your name, claim number, and insurance ID; you may add supporting material such as a clinician’s letter. Follow the notice’s instructions and keep a copy and proof of delivery or submission.
- Request relevant claim documents if needed. Participants in job-based plans may request relevant records and documents without charge, according to the Department of Labor (DOL). Those records can help you understand the plan’s decision and prepare your appeal.
Keep a file of the EOBs and denial letters, appeal request, enclosures, delivery confirmation, and call notes. For each call, record the date and time, the representative’s name and title, and what was discussed. If someone acts for you, include any representative authorization the plan requires.

Ask for expedited review if waiting could seriously harm you
Tell the plan that the standard timetable could seriously jeopardize your life or health, or your ability to regain maximum function, and ask how to submit an expedited appeal. A qualifying urgent case may permit you to request internal and external review at the same time rather than waiting for the internal process to finish. CMS’s federal external-review process also recognizes expedited review for qualifying urgent medical conditions and certain disputes about admission, availability of care, or continued stay after emergency services when the patient has not been discharged.
Explain the urgency clearly and include supporting information if available, but do not delay asking for expedited handling while collecting records. The plan or final denial notice should tell you how to submit the request.

Read the final denial carefully for the external-review instructions, deadline, and recipient. External review is an independent review of eligible denials, including certain disputes involving medical judgment or experimental or investigational treatment. The applicable route may be a state process, a federal process, or an independent review organization, depending on the plan and jurisdiction. A state Consumer Assistance Program or Department of Insurance may help identify the route.
HealthCare.gov’s consumer guidance gives four months after receipt of the denial or final determination to request external review; state procedures or plan terms may differ. Under the HealthCare.gov guidance, standard external review generally has a maximum decision period of 45 days and expedited review 72 hours. CMS gives those same deadlines for the HHS-administered federal route; for that route, an expedited oral notice must be followed by written notice within 48 hours. Use the final notice’s instructions rather than assuming these timeframes or the federal route apply to your plan.
Which route and deadline apply?
| Route | What it addresses | Timing in federal consumer guidance |
|---|---|---|
| Internal appeal | Asks the plan to reconsider its coverage or payment decision. | HealthCare.gov gives a general 180-day period after receipt of a denial notice, and lists 30 days for appeals involving services not yet received and 60 days for services already received. Confirm the controlling deadline in the denial notice and plan documents. |
| Expedited review | Seeks a faster decision when delay could seriously jeopardize life, health, or the ability to regain maximum function; certain ongoing emergency-care disputes may qualify for expedited external review. | Ask the plan how to request it. A qualifying urgent case may allow internal and external review requests at the same time. |
| External review | Requests independent review of an eligible denial after the plan’s internal decision. | HealthCare.gov describes a four-month request period after receipt of the denial or final determination. Its guidance gives up to 45 days for standard review and 72 hours for expedited review; state or plan procedures can differ. |
| No Surprises Act complaint | Raises a possible violation involving a protected out-of-network bill; it is not an appeal of the plan’s coverage decision. | Contact the No Surprises Help Desk at 1-800-985-3059 for guidance. The cited CMS consumer guidance does not give a general complaint deadline here. |
The process depends on the coverage arrangement and jurisdiction. These federal sources address private coverage; Medicare, Medicaid, TRICARE, VA, and other programs have separate procedures.
Where to get help
- Your plan: Use the denial notice, member services, and plan documents to confirm the claim-specific appeal address, form, deadline, and review route.
- DOL Employee Benefits Security Administration: Its claim-procedure guidance explains rights for job-based plans, including access to relevant claim documents.
- State assistance: A state Consumer Assistance Program or Department of Insurance may help with appeals or identify the external-review process.
- Possible surprise-billing violation: CMS’s No Surprises Help Desk is available at 1-800-985-3059.
An appeal is a request for review, not a guarantee of payment. The outcome can depend on the plan contract, medical record, service, care setting, plan type, and applicable state and federal rules.
