Having a long-term disability (LTD) claim denied is devastating – but for most workers covered by an employer-sponsored plan, it is rarely the end of the road. Under the Employee Retirement Income Security Act (ERISA), you have a federally protected right to appeal that decision. Understanding how that process works – and what it demands of you – can make the difference between securing the benefits you are owed and losing them permanently.

What Is the ERISA Appeal Process?

ERISA is the federal law that governs most employer-sponsored benefit plans, including group long-term disability insurance. When an insurer denies, terminates, or reduces your LTD benefits, ERISA requires the plan administrator to give you a written explanation and a formal opportunity to challenge it through an internal appeal.

This internal appeal is not simply a formality. It is a critical legal proceeding. The documents you submit, the medical evidence you present, and the arguments you make become the factual foundation for any federal lawsuit that follows if the appeal is unsuccessful. Federal courts generally cannot consider evidence that was not first submitted during the administrative appeal – which makes getting it right the first time essential.

Why ERISA Appeals Are Different

ERISA claims are governed by federal law rather than state insurance law. Insurers operating under ERISA often receive “discretionary authority,” meaning a court will defer to the insurer’s decision unless it was an abuse of discretion – a high bar that makes the administrative record built during your appeal phase critical.

Procedural mistakes – missing a deadline, incomplete documentation, or the wrong medical evidence – can permanently close the door on your claim, even if your underlying condition clearly qualifies.

Key Steps in the ERISA LTD Appeal Process

Know your deadline. ERISA sets strict timeframes for filing – typically 180 days from the denial letter, though your plan documents may differ. Missing this window can extinguish your right to appeal entirely. See our full guide to ERISA appeal deadlines.

Build your appeal. A strong appeal is far more than a letter of disagreement. It requires a carefully assembled package that directly refutes the insurer’s stated reasons for denial. Our guide on how to appeal a long-term disability denial walks through the process from start to finish.

Gather the right documents. Missing records can sink an otherwise valid claim. Our guide to documents needed for a disability appeal covers exactly what to collect and how to organize it.

Present compelling medical evidence. Treating physician statements, diagnostic records, specialist reports, and functional assessments all play a role. Learn what insurers look for in our guide to medical evidence for an LTD appeal.

Prepare for an Independent Medical Exam. Insurers frequently require claimants to be examined by a physician of their own choosing. These exams carry significant weight. Our guide to independent medical exams in disability claims explains your rights and how to approach the process.

Understand Functional Capacity Evaluations. An FCE measures your actual work-related physical or cognitive abilities. Insurers use results to argue you can perform some form of gainful work. See our breakdown of functional capacity evaluations in disability claims to understand how they work and how to challenge unfavorable findings.

If the appeal is denied. If your internal appeal is unsuccessful, you may have the right to file suit in federal court – but the strength of that case depends almost entirely on the record you built during the appeal. Our guide to what happens after an ERISA appeal is denied explains your options and next steps.

Should You Hire an Attorney?

ERISA disability law is specialized and technically demanding. Many claimants benefit from working with an attorney who focuses on ERISA claims, particularly because mistakes at the appeal stage can be irreversible. Most ERISA disability attorneys work on contingency, meaning they are paid only if you win.

Whether you work with an attorney or proceed independently, the guides linked throughout this page are designed to help you navigate each stage with clarity and confidence.
