How to Read an ERISA Denial Letter and Decide Your Next Step

Quick Summary: When you receive an ERISA denial letter for an employer-sponsored benefit claim, start by identifying four key items: the exact reason for the denial, the deadline to appeal, the name of the plan, and what evidence the insurer or plan administrator claims is missing. These details determine what you must fix, what you must submit, and how fast you must act. Your denial letter shapes the entire appeal record—especially under ERISA’s strict rules—so understanding it early is critical.

At Davis Olszeski Law in St. Louis, Missouri and Illinois, we help clients make sense of complex employer‑sponsored benefit denials governed by the Employee Retirement Income Security Act (ERISA). Whether you are facing a denial involving disability, health, life, or pension benefits, the denial letter is the roadmap for your next move—and often your last chance to build the evidence needed for success.

Why the Denial Letter Matters Under ERISA

ERISA governs most employer-sponsored benefit plans, and its rules are unlike ordinary insurance disputes. Before learning how to respond, it helps to understand the framework. For a clear overview, see What Is ERISA.

When a claim is denied, the plan administrator must send a written explanation outlining why. This letter is not just a formality—it establishes the issues you must address in your appeal and the evidence the administrator says your claim lacks. Under ERISA, courts generally review only the documents submitted during the administrative appeal, not new information added later. That means your denial letter tells you exactly what you must correct before the deadline passes.

The Four Things to Look for First

1. The Denial Reason

Determine whether the denial is based on medical evidence, plan exclusions, administrative issues, missed deadlines, or alleged lack of proof of disability or eligibility. For disability claims, administrators often rely on paper medical reviews from doctors who never examined you. In health and life insurance matters, denials may stem from coverage interpretations or definitions buried in the plan text. Pension denials may cite eligibility rules or service-credit calculations.

2. The Appeal Deadline

Your appeal deadline—usually 180 days for disability and health claims—appears in the letter and is inflexible. Missing this deadline can permanently end your claim. For more detail on these strict timelines, see ERISA Appeal Deadlines.

3. The Plan Name

Every ERISA appeal must be handled under the specific plan that governs your benefit. The denial letter will identify the plan name, which determines what rules apply. Large employers often have multiple plans—long-term disability, short-term disability, health, life, pension—and each has its own definitions, obligations, and procedures.

4. Missing or Insufficient Evidence

ERISA administrators must state what information they relied on and what additional evidence is needed. For long-term and short-term disability claims, this often includes functional capacity assessments, treating physician notes, vocational reports, or objective medical tests. For health or life insurance claims, it may involve medical records, proof-of-loss documents, or policy interpretations. For pension disputes, it might include employment records, plan documents, or benefit calculation materials.

How Denial Letters Affect Different Types of Claims

Disability (Short-Term or Long-Term)

The denial letter determines the medical and vocational evidence you must include in your appeal. Because courts rarely permit new evidence after the appeal, the denial letter essentially defines your entire case.

Health Insurance

Health benefit denials often involve medical-necessity determinations or coverage rules. The letter will specify which guideline or policy was applied and what documentation is needed to challenge it.

Life Insurance & Accidental Death Claims

These denials often cite exclusions, late premium payments, alleged misrepresentations, or questions of coverage. The denial letter explains what documents you must provide to dispute the insurer’s reasoning.

Pension & Retirement Benefits

Pension denials may address eligibility, years of service, benefit calculations, or missing employment records. The denial letter identifies exactly what the administrator believes is missing or incorrect.

Why Your Appeal Depends on the Denial Letter

Under ERISA, your administrative appeal is your only opportunity to create the evidence the court will later review. If your appeal record is incomplete or poorly documented, even the strongest case can fail in litigation. The denial letter is your guide to what must be addressed—and an experienced ERISA lawyer can help ensure that every requirement is met.
