10 Mistakes to Avoid After a Long-Term Disability Denial (2026 Guide)

If your long-term disability claim has been denied, do not assume the insurance company is correct. Many disability claims are denied because of missing evidence, incomplete medical documentation, surveillance, or disputes over how a medical condition affects a claimant’s ability to work. The appeal stage is often the most important opportunity to submit additional evidence and protect your right to disability benefits. Avoiding common mistakes can significantly improve your chances of overturning a disability denial.

Denied Long-Term Disability Benefits? You’re Not Alone.

Receiving a long-term disability denial letter can be one of the most stressful moments in a disability claim. Most claimants are already struggling with serious medical conditions, lost income, mounting medical expenses, and uncertainty about the future. A denial often feels like the insurance company is saying your condition is not serious enough to prevent you from working.

In many cases, however, that simply is not true.

Insurance companies frequently deny legitimate long-term disability claims because they believe there is insufficient evidence to support the claim, because they interpret medical records differently than treating physicians, or because they rely on surveillance, file reviews, or vocational assessments that fail to accurately reflect a claimant’s limitations.

The good news is that a denial does not necessarily mean your claim is over.

Whether your disability claim is governed by ERISA or an individual disability insurance policy, understanding what to do next can dramatically improve your chances of obtaining the benefits you deserve.

What the Courts Have Said About Disability Denials

Many disability claimants assume that once an insurance company denies a claim, there is little that can be done. Fortunately, that is not the law.

Federal courts have repeatedly recognized that disability insurers must conduct fair and reasonable reviews of claims and cannot arbitrarily deny benefits.

In Firestone Tire & Rubber Co. v. Bruch, 489 U.S. 101 (1989), the United States Supreme Court established the framework courts use when reviewing ERISA disability benefit denials. The Court held that, unless a disability plan grants discretionary authority to the insurer, courts generally review benefit denials without deference to the insurance company’s decision.

The Supreme Court further addressed insurer decision-making in Metropolitan Life Insurance Co. v. Glenn, 554 U.S. 105 (2008). There, the Court recognized that a conflict of interest exists when an insurance company both decides whether a claimant qualifies for benefits and pays those benefits from its own assets. Courts may consider that conflict when determining whether a denial was reasonable.

In Black & Decker Disability Plan v. Nord, 538 U.S. 822 (2003), the Supreme Court held that ERISA does not require insurers to automatically defer to treating physicians. However, the Court also emphasized that insurers may not arbitrarily refuse to credit reliable evidence submitted by treating doctors.

These decisions demonstrate an important point: a disability denial is not necessarily the final word. Courts frequently overturn disability denials when insurers fail to properly evaluate the evidence or apply the terms of the policy fairly.

Below are the ten biggest mistakes people make after receiving a disability denial.

1. Assuming the Insurance Company Is Correct

Many people assume that because a large insurance company denied their claim, the decision must be correct.

That assumption can be costly.

Insurance companies deny thousands of disability claims every year. Many of those denials are later overturned on appeal because additional medical evidence, vocational evidence, or legal arguments demonstrate that the initial decision was flawed.

Example

A claimant suffering from severe fibromyalgia was denied because the insurer claimed there was insufficient objective evidence supporting her symptoms. During the appeal process, detailed physician reports, treatment records, and a functional capacity evaluation demonstrated significant physical limitations. The denial was reversed, and benefits were reinstated.

The lesson is simple: a denial is not the final word.

2. Missing the Appeal Deadline

One of the most damaging mistakes is failing to appeal within the required timeframe.

Most employer-sponsored long-term disability plans governed by ERISA require claimants to submit an appeal within 180 days of receiving a denial letter.

Missing that deadline can permanently bar your claim.

Immediately after receiving a denial:

• Save the denial letter.
• Calendar all deadlines.
• Request a copy of your claim file.
• Begin gathering evidence.

The sooner you start, the stronger your appeal can be.

3. Filing an Appeal Without Understanding Why the Claim Was Denied

Every denial letter contains important information.

Insurance companies generally explain why they denied the claim and what evidence they believe is lacking.

Common reasons include:

• Lack of objective medical evidence.
• Failure to meet the policy’s definition of disability.
• Alleged improvement in medical condition.
• Ability to perform sedentary work.
• Inconsistent treatment records.
• Surveillance findings.

A successful appeal directly addresses every reason identified in the denial letter.

Why Insurance Companies Deny Long-Term Disability Claims

One of the most common questions we hear is:

“Why did the insurance company deny my disability claim?”

Some of the most common reasons include:

• Insufficient medical evidence.
• Limited physician support.
• Surveillance footage.
• Social media activity.
• Independent medical reviews.
• Failure to comply with treatment recommendations.
• Transition from “own occupation” to “any occupation” disability definitions.

Understanding the insurer’s reasoning is essential to developing a successful appeal strategy.

4. Relying Solely on Medical Records

Medical records often document diagnoses and symptoms but fail to explain how those symptoms impact a claimant’s ability to work.

Insurance companies focus heavily on functional limitations.

Strong disability appeals frequently include:

• Detailed physician narratives.
• Functional Capacity Evaluations (FCEs).
• Neuropsychological testing.
• Vocational assessments.
• Witness statements from family members and coworkers.

These forms of evidence can be just as important as medical records themselves.

Courts Expect Insurance Companies to Consider All Relevant Evidence

Many disability denials rely heavily on paper reviews conducted by physicians who never personally examine the claimant.

Courts have expressed concern when insurers selectively rely on evidence supporting a denial while disregarding evidence supporting disability. For example, in Montour v. Hartford Life & Accident Insurance Co., 588 F.3d 623 (9th Cir. 2009), the Ninth Circuit criticized an insurer’s reliance on file reviews while discounting substantial evidence from treating physicians.

The lesson is simple: a successful disability appeal should contain comprehensive medical, vocational, and functional evidence that directly addresses the insurer’s reasons for denying benefits.

5. Believing a Diagnosis Automatically Proves Disability

One of the biggest misconceptions in disability law is that a diagnosis alone guarantees benefits.

It does not.

A claimant may have:

• Multiple sclerosis
• Fibromyalgia
• Chronic fatigue syndrome
• Long COVID
• Meniere’s disease
• Major depression
• Anxiety disorders

Yet still receive a denial.

The insurance company’s primary concern is whether the condition prevents the claimant from performing the material duties of their occupation.

The focus should always be on limitations, restrictions, and vocational impact.

A Diagnosis Is Not Enough Under the Law

Federal courts consistently distinguish between having a medical diagnosis and proving disability under the terms of a disability insurance policy.

In Boardman v. Prudential Insurance Co. of America, 337 F.3d 9 (1st Cir. 2003), the court explained that the existence of a medical condition alone does not establish disability. Rather, the relevant question is whether the condition prevents the claimant from performing the material duties of his or her occupation.

This is why successful disability claims focus on functional limitations, restrictions, and vocational impact rather than diagnosis alone.

6. Posting on Social Media

Insurance companies regularly monitor social media accounts.

Photos, comments, videos, and check-ins can all become evidence.

Example

A claimant suffering from chronic fatigue syndrome attended a family wedding and posted photographs online. Although she spent most of the event seated and required several days of recovery afterward, the insurer cited the photographs as evidence that she could engage in normal activities.

Social media posts rarely tell the full story.

Assume anything posted online may eventually be reviewed by the insurance company.

7. Ignoring Surveillance

Insurance companies frequently hire private investigators to observe disability claimants.

Surveillance can include:

• Video recordings.
• Photography.
• Activity monitoring.
• Social media reviews.

Investigators may spend days attempting to capture footage that appears inconsistent with reported limitations.

Even brief periods of activity can be taken out of context.

Example:

A claimant with chronic back pain was videotaped carrying groceries from his vehicle into his home. The insurer argued this activity demonstrated work capacity. However, medical records showed the claimant experienced increased pain afterward and required significant rest. A brief observation rarely captures the full extent of a claimant’s limitations.

Understanding surveillance tactics can help prevent misunderstandings and protect your claim.

8. Failing to Obtain Strong Physician Support

Treating physicians are often the most important witnesses in a disability claim.

Unfortunately, many physicians do not fully understand what disability insurers require.

Strong physician reports should explain:

• Diagnosis.
• Symptoms.
• Restrictions.
• Limitations.
• Prognosis.
• Why the claimant cannot perform occupational duties.

A detailed physician narrative can significantly strengthen an appeal.

Strong Physician Support Can Be Critical

Although ERISA does not require insurance companies to automatically accept the opinions of treating physicians, courts recognize the importance of detailed medical evidence from doctors who regularly treat the claimant.

As the Supreme Court observed in Black & Decker Disability Plan v. Nord, insurers may not arbitrarily disregard reliable medical evidence submitted by treating physicians.

For that reason, detailed physician reports explaining a claimant’s symptoms, restrictions, limitations, prognosis, and inability to work can be among the most persuasive pieces of evidence in a disability appeal.

9. Waiting Too Long to Consult an ERISA Disability Attorney

Many claimants wait until after an appeal has been denied before contacting an attorney.

This can be a serious mistake.

In many ERISA cases, the administrative appeal represents the last opportunity to submit evidence.

Federal courts often limit review to the evidence contained in the administrative record.

That means building a complete record before the appeal deadline expires is critical.

Why the Administrative Appeal Matters So Much

Many disability claimants do not realize that the administrative appeal is often the most important stage of an ERISA disability claim.

Federal courts frequently limit their review to the evidence contained in the administrative record. Evidence that is not submitted during the appeal process may never be considered by a court.

As a result, claimants who submit incomplete appeals may unintentionally weaken their cases long before litigation begins.

This is one reason experienced ERISA disability attorneys focus heavily on developing the strongest possible record before the appeal deadline expires.

10. Trying to Handle a Complex Disability Appeal Alone

ERISA disability law is highly specialized.

Successful appeals often require:

• Medical evidence development.
• Vocational analysis.
• Legal research.
• Policy interpretation.
• Strategic presentation of evidence.

Insurance companies have teams of adjusters, nurses, physicians, vocational consultants, and attorneys evaluating claims.

Claimants should have experienced representation as well.

Recent Court Decisions Continue to Protect Disability Claimants

Courts across the country continue to scrutinize disability insurance companies that fail to conduct fair claim reviews.

While every case is different, judges routinely overturn disability denials where insurers:

• Ignore evidence supporting disability;
• Rely exclusively on non-examining physicians;
• Mischaracterize medical records;
• Overstate surveillance evidence;
• Fail to explain why treating physician opinions were rejected; or
• Interpret policy language unreasonably.

The legal landscape demonstrates that disability claimants have important rights and that an insurance company’s denial should not automatically be accepted as correct.
