Receiving a denial letter for a long-term disability (LTD) claim can be devastating—especially when you’re already dealing with a serious medical condition. But if your disability insurance is provided through your employer, your claim is likely governed by a federal law called ERISA (Employee Retirement Income Security Act of 1974).
ERISA sets the rules for how disability claims must be handled, including your rights when appealing a denial. But it also limits what you can do if you don’t follow those rules exactly. That’s why it’s essential to understand the ERISA appeals process—and how to give yourself the strongest possible chance of success.
In this guide, we’ll walk through the key steps to appeal a denied long-term disability claim under ERISA and explain how the law affects your rights along the way.
Understanding ERISA and Disability Claims
ERISA governs most group disability insurance policies offered through private employers. If your LTD coverage is part of an employee benefits package, it’s almost certainly subject to ERISA regulations.
This means:
You must follow a strict appeals process before you can sue
Your appeal must be fully documented
The court will generally only consider the evidence submitted during the internal appeal
In short, your appeal is your one shot to build a strong case. If you skip steps, miss deadlines, or fail to include key evidence, you may lose your chance to obtain benefits—even in court.
Step 1: Review the Denial Letter Carefully
The first step after receiving a denial is to read the letter in full. ERISA requires insurers to explain:
The specific reasons your claim was denied
The evidence the insurer relied on
The standards or definitions used (e.g., “own occupation” vs. “any occupation”)
Your right to request the claim file
The deadline for filing an appeal (usually 180 days)
Understanding the insurer’s rationale is key to preparing a targeted and effective appeal.
Step 2: Request Your Entire Claim File
You have the legal right under ERISA to request a free copy of your entire claim file, which may include:
Medical records and evaluations
Reports from insurance company doctors or consultants
Surveillance footage or social media evidence (if applicable)
Internal emails or notes from claims adjusters
Vocational assessments
This file is critical for understanding how your claim was reviewed—and what evidence the insurer may be using against you. Request it in writing as soon as possible.
Step 3: Understand the Plan’s Definition of Disability
Long-term disability policies often contain definitions like:
Own Occupation: You’re disabled if you can’t perform your specific job
Any Occupation: You’re disabled only if you can’t perform any job for which you’re reasonably qualified
Many LTD policies start with an “own occupation” standard for the first 24 months, then switch to “any occupation.” Denials often hinge on how the insurer interprets this transition.
Carefully review the Summary Plan Description (SPD) or full plan document to understand which standard applies—and how it affects your case.
Step 4: Gather Supporting Medical Evidence
Your appeal should include as much supporting documentation as possible, especially from medical professionals. Helpful evidence may include:
Updated medical records
Physician letters explaining your functional limitations
Reports from treating specialists
Objective test results (MRIs, bloodwork, psychological evaluations)
Functional capacity evaluations (FCEs)
Vocational expert opinions showing you can’t work
Remember: you cannot submit new evidence later if your appeal is denied and you go to court. The administrative appeal is your only chance to build the record.
Step 5: Write a Strong Appeal Letter
Your appeal letter should clearly and concisely explain why the denial was wrong. Address the insurer’s reasons point by point and include citations to the medical evidence or policy language that supports your claim.
Some tips for writing your appeal:
Be professional, factual, and respectful
Avoid emotional arguments—focus on the evidence
Point out errors or omissions in the denial letter
Cite relevant medical definitions and test results
Emphasize consistency in your medical history and work restrictions
If your condition has worsened since the original claim, include updated records or notes from your doctor to show progression.
Step 6: Meet the Appeal Deadline
ERISA gives you 180 days from the date of the denial to submit your appeal. If you miss this deadline, you may lose your right to appeal or sue altogether.
Submit the appeal in writing—via certified mail or another trackable method—to ensure proof of receipt. Keep a complete copy for your records.
Step 7: Consider Hiring an ERISA Attorney
Because ERISA rules are complex and unforgiving, many claimants benefit from working with an attorney who specializes in long-term disability and ERISA law.
An experienced lawyer can:
Analyze your denial and plan language
Help gather and present medical and vocational evidence
Draft a persuasive appeal letter
Communicate directly with the insurer on your behalf
Prepare your case for litigation if needed
Most ERISA disability attorneys work on a contingency fee basis, meaning you pay nothing unless you win your appeal or recover benefits.
Step 8: Wait for a Decision
After you submit your appeal, the insurance company must respond within a reasonable timeframe—typically:
45 days, with a possible 30-day extension if additional information is needed
During this time, they must conduct a full and fair review by someone who was not involved in the original denial. If the appeal is denied again, you will receive a final denial letter.
At that point, your only remaining option is a federal lawsuit—which must be based entirely on the record you submitted during the appeal.
What Happens If You Win Your Appeal?
If the insurer approves your appeal, they will begin paying your long-term disability benefits, including any back pay owed since the original claim was denied. You may also need to:
Provide ongoing updates and medical records
Comply with vocational rehabilitation programs
Apply for Social Security Disability Insurance (SSDI), if required by your policy
Winning the appeal is a huge step, but it doesn’t always mean the battle is over. Many insurers periodically review your claim, so staying proactive and prepared is key.
Final Thoughts: Be Strategic, Not Reactive
Getting a long-term disability denial is frustrating, but reacting emotionally or rushing through an appeal can harm your case. ERISA’s strict procedures mean that every document, deadline, and piece of evidence matters.
Treat your appeal as if it’s your day in court—because in many ways, it is.
Take the time to understand your rights, build a detailed record, and consider working with an ERISA disability attorney to strengthen your chances. With the right strategy and support, many appeals can succeed—and secure the benefits you deserve.
