Unum Disability Claim Denied? Here's What to Do Next

If Unum has denied your long-term disability (LTD) claim, you are not alone -- and you are not out of options. Unum is one of the largest disability insurers in the United States, processing hundreds of thousands of claims each year. While many claims are approved, Unum denies a significant number using tactics that follow predictable patterns. Understanding these patterns is the first step toward overturning your denial.

Every employer-sponsored Unum disability policy is governed by the Employee Retirement Income Security Act (ERISA), a federal law that establishes strict rules for how insurers must handle claims and appeals. Under ERISA, you have powerful rights -- but also critical deadlines. Missing these deadlines can permanently bar you from challenging Unum's decision.

Why Unum Denies Disability Claims

Unum denies long-term disability claims for a variety of reasons, but certain tactics appear repeatedly. Understanding Unum's approach gives you a strategic advantage when preparing your response.

Unum is notorious for the "own occupation" to "any occupation" switch at the 24-month mark. For the first two years, Unum evaluates whether you can perform your specific job. After 24 months, the definition quietly shifts to whether you can perform any occupation for which you are qualified by education, training, or experience. This is the single most common trigger for Unum LTD terminations.

Unum aggressively uses surveillance -- hiring private investigators to follow claimants, video-record daily activities, and compile evidence that you are more functional than your medical records suggest. A single video of you carrying groceries can be used to justify termination.

Unum relies heavily on Independent Medical Examinations (IMEs) conducted by doctors on their payroll. These physicians rarely support claims and frequently contradict treating physicians.

Unum demands excessive documentation and then uses any gap in treatment or paperwork as grounds for denial. If you miss a single follow-up appointment, Unum may argue you are no longer disabled.

These denial tactics are not unique to Unum, but the company has developed specific processes around them. Knowing what to expect allows you to build a stronger case from the start.

Your ERISA Rights When Unum Denies Your Claim

Under ERISA and its implementing regulation 29 CFR section 2560.503-1, Unum must follow specific procedures when denying your disability claim:

• Written notice of denial -- Unum must provide a written explanation of the specific reasons for the denial, the plan provisions on which the denial is based, and a description of any additional information needed to perfect the claim (29 U.S.C. section 1133).
• 180-day internal appeal deadline -- You have 180 days from receiving the denial notice to file an internal appeal. This deadline is strictly enforced.
• Full and fair review -- On appeal, Unum must conduct a full and fair review, considering all evidence you submit, not just the evidence that supports denial.
• Independent reviewer -- Under the 2018 ERISA disability claims regulation, the appeal must be reviewed by someone who was not involved in the initial denial decision and who does not report to the person who made the initial decision.
• No deference to initial denial -- The appeal reviewer must give no deference to the initial adverse determination.

If Unum denies your internal appeal, you may have the right to External Independent Review: Complete Guide" class="auto-link">external review under DOL Technical Release 2010-01 and ACA section 2719 (for non-grandfathered plans). You also have the right to file a lawsuit in federal court under ERISA section 502(a)(1)(B).

Step-by-Step: What to Do After a Unum Denial

Step 1: Read Your Denial Letter Carefully

Unum's denial letter contains critical information: the specific reason for denial, the policy provisions cited, the appeal deadline, and instructions for filing an appeal. Identify exactly what Unum is claiming and which policy language they rely on.

Step 2: Request Your Complete Claim File

Under ERISA, you have the right to receive copies of all documents, records, and other information relevant to your claim. Request Unum's complete file, including internal notes, medical review reports, surveillance records, vocational analyses, and the clinical criteria used to evaluate your claim. This reveals exactly what evidence Unum relied on and what gaps you need to address.

Step 3: Obtain Updated Medical Evidence

The most effective way to fight a Unum denial is with strong medical evidence from your treating physicians. Ask your doctors to provide:

• Detailed narrative reports describing your diagnosis, treatment, prognosis, and functional limitations
• Specific restrictions and limitations (hours of sitting, standing, walking, lifting; cognitive limitations; need for breaks)
• Objective test results supporting the diagnosis (imaging, lab work, nerve conduction studies, neuropsychological testing)
• An explanation of why Unum's medical reviewers or IME physicians reached incorrect conclusions

Step 4: Consider Independent Expert Reports

If Unum relied on an IME, FCE, or vocational analysis, consider obtaining your own independent evaluations. An independent medical examination by a specialist in your condition, an independent functional capacity evaluation, or a vocational expert report challenging Unum's analysis can be powerful appeal evidence.

Step 5: File Your Internal Appeal Within 180 Days

Submit your appeal via certified mail and keep copies of everything. Your appeal letter should reference your policy number, claim number, and the specific denial reason. Address each of Unum's stated reasons for denial with specific evidence. Cite the applicable ERISA regulations and your right to a full and fair review.

ERISA Deadlines and External Review Rights

Critical warning: Under ERISA, federal courts generally limit their review to the "administrative record" -- the evidence in your claim file at the time of the final appeal decision. This means your internal appeal is your last chance to submit evidence. Do not hold anything back.

What If Unum Denies Your Appeal?

If Unum denies your internal appeal, you have several options:

1. External review -- For non-grandfathered plans, request an independent external review within 4 months of the final internal denial. An independent reviewer will evaluate your claim without any connection to Unum.
2. Federal court lawsuit -- Under ERISA section 502(a)(1)(B), you can file a lawsuit in federal court to recover benefits due under your plan. Consult an ERISA attorney before filing.
3. Department of Labor complaint -- File a complaint with the Employee Benefits Security Administration (EBSA) at dol.gov/agencies/ebsa.
4. State insurance department -- For fully insured plans, file a complaint with your state department of insurance.

Take Action Now
