Unum Fibromyalgia Disability Claim Denied

Fibromyalgia is one of the most frequently denied disability conditions — and Unum is one of the most aggressive deniers. They routinely label fibromyalgia claims as based on "self-reported symptoms" and apply heightened evidentiary standards that courts have repeatedly found improper. Here's how to fight a Unum fibromyalgia denial.

Why Unum Denies Fibromyalgia Claims

Unum's standard arguments against fibromyalgia claims:

• "Self-reported symptoms" — invoking a policy limitation that caps benefits for conditions without "objective" test results
• "Not totally disabled" — claiming that because there's no positive imaging or lab test, you can work
• "Mental/nervous disorder" — incorrectly classifying fibromyalgia as a psychiatric condition to trigger the 24-month limitation
• "IME disputes" — their reviewing physicians often contradict your rheumatologist
• "FCE results" — functional capacity evaluations timed after brief activity windows, missing the hallmark post-exertional malaise of fibromyalgia

The "Self-Reported Symptoms" Trap

Many Unum group policies contain language limiting benefits for conditions "based primarily on self-reported symptoms" to 24 months. Unum aggressively applies this to fibromyalgia.

However, courts have repeatedly ruled that:

1. Fibromyalgia IS a recognized medical condition — the American College of Rheumatology has established diagnostic criteria (the 2010 ACR Criteria) that are objective clinical findings, not mere patient reports
2. Tender point examinations constitute objective clinical findings
3. Sleep studies, cognitive testing, and pain sensitivity assessments provide objective evidence
4. The diagnosis must be made by a rheumatologist or treating physician — Unum cannot simply relabel it as "self-reported"

In Mead v. Reliance Standard Life Insurance, courts found that applying the self-reported symptoms limitation to fibromyalgia was arbitrary and capricious when the diagnosis was based on clinical examination.

Building Your Fibromyalgia Disability Appeal

Medical evidence checklist:

• Formal fibromyalgia diagnosis from a rheumatologist using 2010 ACR Criteria
• Documented widespread pain index (WPI) score and symptom severity scale (SS) score
• Sleep study results showing non-restorative sleep or alpha-delta wave intrusion
• Cognitive testing results if "fibro fog" is part of your disability
• Neuro-inflammatory biomarker testing where available
• Documented failed treatment attempts (medications, physical therapy, pain management)

Functional evidence:

• Functional capacity evaluation conducted over multiple days (single-day FCEs miss fibromyalgia's post-exertional pattern)
• Pain diary documenting symptom fluctuation, bad days, and activity limitations
• Treating physician's detailed functional assessment (lifting, sitting, standing tolerances)
• Statements from family members or caregivers documenting daily limitations

Challenge the "mental/nervous" reclassification: If Unum tried to reclassify your fibromyalgia as a psychiatric condition, include a letter from your rheumatologist explicitly stating that fibromyalgia is a neurological pain processing disorder, not a mental/nervous condition.

Federal Circuit Court Precedent

Multiple federal circuit courts have found Unum's fibromyalgia denials arbitrary:

• Schwarzwaelder v. Merrill Lynch (3rd Cir.) — no positive MRI/CT required for fibromyalgia
• Anderson v. Suburban Teamsters (7th Cir.) — fibromyalgia diagnosed by exclusion is still legitimate
• Holmstrom v. Metropolitan Life Insurance (7th Cir.) — insurer cannot demand objective evidence that doesn't exist for the condition

Cite the circuit precedent applicable to your federal district in your appeal letter.
