When a health plan denies emergency care

A denial after an emergency visit can leave you sorting out paperwork when you already have a lot to manage. Start with the notice, identify exactly what the plan decided, and confirm the instructions that apply to your coverage.

Practical steps after a denial

  1. 1. Read the denial notice and explanation of benefits

    Find the date of the notice, the visit and claim numbers, the reason given, and the plan terms or rule the plan says it applied. A code or short phrase may not explain the decision by itself. You can ask the plan for a fuller explanation and for the records or criteria it considered.

    Look for the appeal deadline, required form, where to send it, accepted submission methods, and instructions for an urgent review. Keep the envelope or save the electronic notice so you can refer to when it arrived.

    • Compare the denial notice with the Explanation of Benefits (EOB) and each bill; they may describe different claims or charges.
    • Ask whether the plan denied the whole claim or only a particular service, provider, or amount.

  2. 2. Confirm which appeal process applies to your plan

    Appeal rights, deadlines, forms, and outside review options can differ by plan type and state. If coverage is through work, ask the plan administrator whether it is fully insured or self-funded and request the plan’s claim and appeal procedures. The U.S. Department of Labor’s Employee Benefits Security Administration (EBSA) provides information for many private-sector job-based plans.

    Marketplace or individual coverage, employer coverage, Medicare, Medicaid or CHIP, and other public or military coverage may use different processes. For Medicare or Medicaid and CHIP, follow the program-specific notice and official program instructions. Do not assume a deadline or form from another plan applies to yours.

    • Use the denial notice and plan documents to identify the office or plan administrator that accepts an appeal.
    • Ask your state insurance department or a CMS-listed Consumer Assistance Program which official channel can help with your coverage type.

  3. 3. Ask the plan what it needs to review the decision

    Call the number on the notice or member card if anything is unclear. Ask what reason was used, which plan language applies, what information the reviewer considered, and what additional documents could be considered. If the decision concerns whether the visit met the plan’s emergency-care criteria, ask what information about the visit the plan relied on.

    Ask whether an expedited or urgent appeal is available if waiting could seriously affect access to care. Confirm the request method and timing directly with the plan or the official program handling your coverage.

    • Write down the call date, time, representative’s name or ID, what was explained, and any reference number.
    • Request the appeal form, exact submission address or portal, and confirmation method.

  4. 4. Gather the records connected to the visit and denial

    Keep copies of the documents you send and keep the originals. Ask the plan or care providers how to obtain missing records. Include only information relevant to the denial and follow the plan’s instructions for submitting personal health information.

    • Plan and claim records: denial notice, EOB, claim number, member ID, plan handbook or evidence/certificate of coverage, Summary of Benefits and Coverage, and any cited emergency-care or appeal policy.
    • Billing records: itemized emergency-department and provider bills, ambulance bills, receipts or payment records, and related messages from the insurer, hospital, physicians, labs, or other providers.
    • Care records: emergency-department registration or triage notes, clinician notes about the symptoms at presentation, test or imaging results, discharge summary, and relevant ambulance or follow-up records.
    • Your own records: call notes, names or reference numbers, copies of forms and letters, submission confirmations, and the date each document was sent.

  5. 5. Send the appeal using the instructions for your plan

    In your own words, identify the visit and claim, state which decision you are asking the plan to reconsider, and briefly connect your explanation and attached records to the reason in the notice. A treating clinician may be able to explain relevant records if you ask them, but confirm whether the plan requires a particular form or statement.

    Use the form, address, portal, fax, or other method named in your notice or plan documents. Keep a full copy and proof of delivery or the confirmation number. If a bill appears to involve a coding or claim-submission issue, you can also ask the provider whether it can review or correct its claim.

    • Before sending, confirm the due date, required documents, signature rules, and whether the plan accepts the method you chose.
    • Keep the response and read it for any next review option and its separate instructions.

A coverage denial and a surprise bill are different issues

A health plan’s decision not to pay a claim is different from a provider billing you for out-of-network charges. CMS explains that, when a plan subject to the federal No Surprises Act covers emergency services, it cannot require prior authorization for emergency care and must assess an emergency based on the symptoms at the time of care, not solely on the final diagnosis code. The Act also protects many people with eligible coverage from surprise out-of-network bills for most emergency services. These protections have a defined scope: they do not decide every coverage question or guarantee that every claim will be paid, and the Act does not cover ground ambulance services.

If your concern is an out-of-network emergency bill or a possible violation of federal surprise-billing protections, CMS has a separate help and complaint process. You can also check the CMS state consumer-help information. If the plan denied coverage or payment, follow the plan’s appeal notice as well; a billing complaint does not replace an appeal deadline.

Confirm deadlines, forms, and where to send documents

Appeal procedures and rights may vary with plan type and state law. A state may administer external review differently; employer plans can have different regulators depending on how the plan is funded; Medicare and Medicaid/CHIP use program-specific notices and appeal channels. The denial notice and your plan or program documents are the place to confirm the deadline, required forms, mailing or online submission method, and whether urgent review is available.

For private coverage, HealthCare.gov and CMS explain general internal and external appeal options. For many private-sector employer plans, DOL EBSA provides claim guidance. For Medicare, use Medicare.gov; for Medicaid or CHIP, use the official state contact linked by Medicaid.gov. CMS also lists state consumer assistance resources and other help by state.
