Writing an ERISA appeal letter: A step-by-step guide

On Behalf of | Jun 19, 2026 | ERISA Process And Procedures

After months of medical treatment and mounting expenses, a disability claim denial feels like one more obstacle. For those whose disability plan is governed by the Employee Retirement Income Security Act (ERISA), claimants have the right to appeal. However, certain plans are exempt, including church plans and government plans. Writing a strong appeal letter is crucial to challenging a claim that was wrongly denied. Knowing how to structure the appeal can help you present your case.

Writing the statement of intent

The appeal letter should begin with a clear statement of intent. Start by including identifying information. This includes the policy number, claim number and full name. The opening section should be direct and professional. It should make clear what action is being requested from the insurance company.

You may reference the date of the denial letter to establish a timeline. ERISA requires insurance companies to provide at least 180 days to file an appeal. Missing this deadline could mean losing your right to appeal the denial.

Gathering medical evidence

New medical records can help support your appeal. Under ERISA rules, claimants have the right to submit additional evidence during the appeal process. Insurance companies must consider this new information before making a final decision. In most cases, the appeal stage is the only opportunity to introduce evidence before the administrative record closes.

Consider gathering the following types of medical evidence:

  • Updated records from treating doctors
  • Recent test results and scans
  • Current notes about ongoing symptoms
  • Doctor statements about work limits
  • New medical evaluations
  • Opinions from specialists
  • Records showing how the condition has worsened

Submit evidence that directly responds to the denial. It can help to organize these chronologically to create a clear narrative about your condition.

Addressing each denial reason

The appeal letter should address every reason for the denial. Review the denial letter carefully to identify each stated reason. Respond to these points one by one. This ensures that no denial reason goes unchallenged. It also shows the claim meets all policy requirements.

If the insurer said the condition does not meet the policy definition of disability, cite the exact policy language. You can also show how the medical evidence meets those requirements. You may also provide employment records and job descriptions. These can show how the condition prevents work duties. Louisiana residents should note that while state insurance laws exist, ERISA often preempts state regulations for employer-sponsored plans.

Building your ERISA appeal

Many people struggle to communicate the full extent of their limitations in writing. Understanding the structure and requirements of an appeal letter can help overcome this challenge. A well-prepared appeal can strengthen your case and protect your right to benefits.
