When your long-term disability claim is denied, the instinct of most claimants is to go back to their treating physician, get a stronger letter, and submit it with the appeal. It seems logical: your doctor knows your condition better than anyone, and their professional judgment should carry significant weight. The problem is that under the ERISA framework governing most employer-sponsored LTD claims, a treating physician’s opinion, even a thorough and well-documented one, is often not enough on its own to overturn a denial. Understanding why, and what additional evidence it takes to win, is essential before you file your appeal.
How Insurers Discount Treating Physician Opinions
Insurance companies routinely receive detailed opinions from treating physicians and discount them anyway. There are several mechanisms they use to do this legitimately within the ERISA framework.
First, the U.S. Supreme Court ruled in Black & Decker Disability Plan v. Nord that ERISA plan administrators are not required to give treating physicians’ opinions special deference, the same deference that applies in Social Security disability cases. This means your insurer can give equal or greater weight to an opinion from an IME physician they hired and paid for, even when that physician spent 20 minutes with you compared to your treating doctor’s years of care.
Second, insurers frequently characterize treating physician opinions as based on “subjective” self-reports from the patient rather than objective medical findings. If your doctor’s records reflect your reported symptoms, pain levels, fatigue, cognitive difficulty, without correlating them to measurable functional impairments supported by diagnostic testing, the insurer will often dismiss them as inadequately objective.
Third, insurers use internal medical reviewers, physicians on their payroll who review paper records without ever examining the claimant, to contradict treating physician findings. These paper reviewers are rarely identified in denial letters by name, but their conclusions often form the actual basis for the denial.
What “Objective Evidence” Actually Means to an Insurer
When an insurer says your claim lacks sufficient objective evidence, they mean something specific: they want measurable data from diagnostic testing or standardized assessments that corroborates your reported functional limitations. Lab results, imaging studies, neuropsychological testing, pulmonary function tests, functional capacity evaluations, these are the kinds of objective evidence insurers treat as credible.
For conditions that are genuinely disabling but difficult to measure objectively, fibromyalgia, chronic fatigue syndrome, long COVID, major depressive disorder, chronic pain, this standard creates a significant challenge. The conditions are real and documented in clinical literature, but they don’t always produce the kind of hard imaging or lab data that insurance reviewers treat as definitive.
The answer is not to accept the insurer’s framing but to challenge it with the right type of specialist evidence. A functional capacity evaluation (FCE) measures what a claimant can actually do, how long they can sit, stand, walk, lift, and sustain concentration, in a standardized, objectively scored format. Neuropsychological testing provides quantifiable data on cognitive limitations. Pain management specialists can document the objective basis for chronic pain in ways general practitioners often don’t. These evaluations provide the “objective” layer that treating physicians’ routine notes sometimes lack.
The FAQs on fighting a denied LTD claim address common questions about what types of evidence are most effective in challenging an insurer’s “insufficient documentation” denial, including when specialist evaluations are worth obtaining and how they’re used in appeals.
The Role of Vocational Experts
Medical evidence establishes what your physical and cognitive limitations are. Vocational evidence bridges the gap between those limitations and your ability to work, which is ultimately what the LTD determination is about. Many claimants win on medical evidence alone, but cases involving any-occupation denials, functional capacity disputes, or complex medical conditions often require vocational expert testimony to succeed.
A vocational expert evaluates your limitations, your work history, your education, your age, and local labor market conditions to assess whether the jobs the insurer claims you could perform are actually available, realistic, and within your functional capacity. The insurer’s vocational assessment almost always concludes that jobs exist that you could perform. An independent vocational expert’s assessment often reaches very different conclusions when applied to the actual constraints of your situation.
If your denial was based on a vocational determination, either at the initial stage or at the 24-month own-to-any-occupation transition, working with attorneys who handle LTD denial appeals and regularly engage vocational experts gives you the most direct path to challenging that evidence.
Carrier-Specific Medical Review Patterns
Different LTD insurers have documented tendencies in how they conduct medical reviews and what types of evidence they credit or discount. If your claim was denied by Anthem, for instance, understanding how attorneys approach Anthem-specific LTD denials includes knowing which evidence arguments have been most effective with that carrier’s reviewers and internal appeal processes. Generic appeal strategies are less effective than ones built around the specific insurer you’re dealing with.
Building the Right Expert Team for Your Appeal
The practical question most claimants face is which experts are worth obtaining for their specific appeal. The answer depends on the denial reason and your underlying condition, but a few general principles apply:
Always start with your treating physician, but go further. Ask your doctor to provide a detailed functional limitations opinion, not just a letter restating your diagnosis. Specifically ask them to address what you can and cannot do in functional terms, how your condition has progressed, why it prevents you from performing your occupational duties, and whether your medications affect your functioning. Then supplement that opinion with specialist evaluations where the insurer has claimed documentation is insufficient.
Match the expert to the denial reason. If the denial cited lack of objective evidence, neuropsychological testing or a functional capacity evaluation addresses that directly. If the denial cited a vocational determination, a vocational expert is the priority. If the denial is based on a biased IME, a specialist rebuttal is most important.
Don’t wait for litigation to gather evidence. Under ERISA, the administrative appeal is almost always your last opportunity to submit new evidence. Once the appeal window closes and litigation begins, courts are generally limited to the record that was before the insurer. Expert evidence not submitted during the appeal typically cannot be introduced in court.
Before submitting your appeal, use the LTD denial appeal checklist from Kantor & Kantor to make sure you haven’t missed any critical evidentiary components. And if you’re evaluating whether you have a viable claim worth pursuing, a free case review for long-term disability denial can help you assess the strength of your medical and vocational evidence before investing time and money in an appeal.
Your doctor’s opinion is the foundation. But in most contested LTD appeals, it’s the expert evidence built around that foundation that determines the outcome.
