Long-Term Disability Insurance Claim Denied? How to Appeal

Losing a long-term disability (LTD) claim — or having benefits terminated after months or years of payments — can be financially catastrophic. These benefits often represent the primary source of income during a period when working is medically impossible. A denial is not the final word. Most denials can be challenged through a formal appeal process governed by either ERISA (for employer group plans) or state contract law (for individual policies), and many are overturned when the right evidence is assembled and the right legal arguments are made.

Why Insurers Deny Long-Term Disability Claims

Definition of Disability Disputes (Own-Occupation vs. Any-Occupation)

LTD policies typically use one of two disability definitions. "Own-occupation" policies pay benefits if you cannot perform the material duties of your specific occupation. "Any-occupation" policies require that you be unable to perform any occupation for which you are reasonably suited by education, training, or experience. Most group LTD policies start with an own-occupation definition for the first 24 months and then shift to any-occupation, which significantly raises the bar. Denials frequently occur at the transition point when the insurer argues you can perform some kind of work, even if it is not your prior profession.

Lack of Objective Medical Evidence

Insurers frequently deny or terminate LTD benefits by arguing that the claimant's limitations are not supported by objective clinical evidence — particularly for conditions like fibromyalgia (ICD-10: M79.3), chronic fatigue syndrome (G93.3), depression (F32.9), anxiety disorders (F41.1), or chronic pain conditions that rely heavily on subjective reporting. The insurer will point to normal imaging or laboratory results as evidence that the disability is not as severe as claimed, even when subjective functional limitations are well-documented.

Independent Medical Examination (IME) Conflicts

Insurers routinely order their own Independent Medical Examinations using physicians selected and paid by the insurer. These physician-selected IMEs frequently conclude that the claimant is capable of returning to work. Peer-to-peer clinical disagreements of this type are the basis for a large proportion of LTD terminations and deserve direct rebuttal with your own treating physician's functional capacity documentation.

Functional Capacity Evaluation (FCE) Misuse

Insurers may order Functional Capacity Evaluations (FCEs) to assess what physical or cognitive tasks a claimant can perform. FCE results can be used against you if the evaluation shows you can perform sedentary work for six or more hours per day. FCEs are snapshots that often fail to capture fluctuating, episodic, or progressive conditions — and they can be challenged as methodologically incomplete.

Surveillance and Social Media Evidence

Insurers conduct video surveillance and monitor social media activity. A single photograph of you carrying groceries or attending an event can be used to dispute disability claims, regardless of how you function on a typical day or during flare-ups of a relapsing condition. Documenting the episodic nature of your condition over time is critical to rebutting surveillance evidence.

Mental Health Benefit Limitations

Many LTD policies cap mental health disability benefits at 24 months, even for severe, well-documented psychiatric conditions. Claimants disabled by depression, bipolar disorder, PTSD, or anxiety disorders frequently face benefit termination at the 24-month mark regardless of clinical severity.

How to Appeal a Long-Term Disability Denial

Step 1: Read the Denial Letter and Identify the ERISA Deadline

If your LTD plan is employer-sponsored, it is almost certainly governed by ERISA (29 U.S.C. §1001 et seq.). Under ERISA regulations (29 CFR §2560.503-1), you have 180 days from the denial letter to file an internal administrative appeal — and this deadline is strictly enforced. Missing it can forfeit your right to any future legal action. Read the denial letter carefully and note the appeal deadline. The denial letter must under ERISA specify the exact reason for denial, the plan provisions relied upon, and describe your appeal rights.

Step 2: Request the Entire Claim File

Under ERISA, you are entitled to the complete claim file — all records, reports, notes, IME reports, surveillance evidence, and internal insurer communications used to evaluate your claim. Request the full claim file in writing immediately. This document is the foundation of your appeal — you cannot effectively rebut the insurer's rationale without knowing exactly what evidence they used and what conclusions their reviewers reached.

Step 3: Obtain Comprehensive Medical Evidence From Your Treating Physicians

Your treating physicians must provide detailed, function-specific documentation that goes beyond a diagnosis. Request letters that describe: (1) the specific ICD-10 diagnosis codes; (2) clinical findings that support the functional limitations; (3) the treating physician's specific opinion on your ability to stand, sit, walk, lift, concentrate, maintain attention, and interact with others over the course of a standard workday; (4) the expected duration of the limitation; and (5) a direct response to the conclusions in any IME or FCE report the insurer cited.

Step 4: Commission a Vocational Expert Assessment

For any-occupation disability disputes, a vocational expert can assess whether your functional limitations actually preclude you from performing any occupation for which you are qualified. A vocational expert report that identifies no available occupation matching your functional capacity directly rebuts the insurer's any-occupation determination with professional authority that carries weight in ERISA administrative appeals and subsequent litigation.

Step 5: Submit a Complete Written Administrative Appeal

Submit your written appeal within the 180-day ERISA window. Include the denial letter, your complete medical records, treating physician letters with functional capacity opinions, a vocational expert report if applicable, rebuttals to IME and FCE conclusions, and any surveillance rebuttal documentation. Under ERISA, the administrative appeal record is the complete record for any subsequent litigation — evidence not submitted at the appeal stage generally cannot be introduced in court. Make the appeal exhaustive.

Step 6: Pursue ERISA Litigation or State Law Remedies After Exhaustion

If the ERISA administrative appeal is denied, you may file a lawsuit in federal district court under 29 U.S.C. §1132(a)(1)(B). Courts review ERISA LTD denials under either a de novo standard or an abuse of discretion standard depending on whether the plan grants the insurer discretionary authority. Consult an ERISA attorney before this step — the legal standard that applies to your claim significantly shapes litigation strategy.

What to Include in Your Long-Term Disability Appeal

• Denial letter and complete claim file obtained from the insurer, including IME reports, FCE results, and surveillance documentation
• Treating physician letters with ICD-10 codes, clinical findings, specific functional capacity opinions, and direct rebuttals of insurer-ordered IME conclusions
• Specialist records: neurologist, psychiatrist, rheumatologist, or other specialists whose findings support the claimed functional limitations
• Vocational expert report for any-occupation definition disputes, establishing that your functional limitations preclude available employment
• ERISA appeal rights statement asserting your rights under 29 CFR §2560.503-1 and requesting the complete claims administration record
