Can You Get Long Term Disability Benefits for a Chronic Illness in 2026?

Written by Eric Shore, a personal injury and disability lawyer and the founder of the Law Offices of Eric A. Shore.

Short Answer

Yes. A chronic illness can qualify for long term disability benefits if medical evidence shows the condition prevents you from performing the duties of your occupation. Most employer disability policies are governed by the federal Employee Retirement Income Security Act (ERISA), which establishes rules for disability claims and appeals.

While some people also apply for Social Security Disability Insurance (SSDI), the primary income protection for many workers comes from their long term disability insurance policy.

Eric Shore, a disability lawyer who has represented claimants for more than 30 years, often explains that many legitimate disability claims fail for one simple reason: The medical records describe symptoms but do not clearly explain how those symptoms prevent reliable work.

Key Takeaway

Chronic illnesses can qualify for long term disability benefits when medical evidence shows functional limitations that make consistent work impossible. The diagnosis alone is rarely enough. What matters most is how the condition limits work ability.

What Is Long Term Disability Insurance?

Short definition: Long term disability insurance replaces part of a worker’s income when a medical condition prevents continued employment.

Employer-provided policies usually pay a percentage of pre-disability income after a waiting period. Large insurance carriers frequently involved in disability claims include:

•  Unum, MetLife, and Cigna
•  Prudential and Lincoln Financial
•  Reliance Standard, The Hartford, and Sun Life

These insurers evaluate claims using medical records, physician opinions, occupational duties, and sometimes independent medical examinations.

What Is ERISA?

Short definition: ERISA is the federal law that governs most employer-sponsored benefit plans, including long term disability insurance.

The statute appears at 29 U.S.C. §1001 et seq. ERISA establishes rules for plan administration, claim procedures, and the mandatory appeal process when disability benefits are denied. Because ERISA is federal law, many disability disputes are ultimately reviewed in federal court.

When Chronic Illness Qualifies for Long Term Disability

> Short definition: A chronic illness qualifies for long term disability when medical evidence shows the condition prevents consistent full-time work.

Common conditions involved in disability claims include:

•  Lupus and Multiple Sclerosis
•  Crohn’s Disease and Fibromyalgia
•  Chronic Fatigue Syndrome and Autoimmune Disorders
•  Severe Rheumatoid Arthritis and Neurological Disorders

Many of these illnesses fluctuate. Even when symptoms temporarily improve, a person may still qualify for disability benefits if the condition prevents reliable full-time work.

The Evidence That Determines Most LTD Claims

Short definition: Functional limitations documented in medical records usually determine whether a disability claim succeeds.

Medical records should explain how symptoms affect the ability to perform work activities such as:

•  Sitting, standing, or walking for extended periods.
•  Maintaining concentration and regular attendance.
•  Performing sustained physical activity.

The diagnosis matters. However, documented work limitations usually determine whether a claim is approved.

How Disability Is Defined in LTD Policies

Short definition: Most ERISA-governed disability policies define disability using an Own Occupation or Any Occupation standard.

Most policies begin with an Own Occupation definition (disabled if you cannot perform your specific job). After a period of time—often 24 months—many policies shift to an Any Occupation definition. At that stage, the insurer may argue the claimant can perform any job consistent with their education, training, or experience. This change is a primary reason benefits are terminated.

The ERISA Appeals Process

> Short definition: ERISA requires disability plans to provide an administrative appeal before a claimant can challenge a denial in court.

Federal claim procedure regulations (29 C.F.R. §2560.503-1) generally provide at least 180 days to appeal a denial. During this stage, claimants may submit:

 * Updated medical records and physician opinions.

 * Functional capacity evaluations and vocational evidence.

 * Legal arguments regarding the policy definition of disability.

The 2026 ERISA Landscape: Courts reviewing disability denials generally evaluate the insurer’s decision based only on the administrative record created during the appeal stage. If critical evidence is not submitted then, it may never be considered by a court.

Why Long Term Disability Claims Are Often Denied

Short definition: Most disability claims are denied because medical records fail to clearly connect symptoms to work limitations.

 * Incomplete medical records: Symptoms are described, but work capacity is not.

 * Gaps in treatment: Insurers argue inconsistent care suggests the condition isn’t disabling.

 * Insurance company medical reviews: In my more than 30 years representing disability claimants, I have seen insurers rely heavily on “paper-only” reviews by doctors who never examine the patient.

 * Surveillance: Insurers use activity data to argue a claimant is more functional than reported.

 * Missed deadlines: Missing the 180-day appeal window can eliminate your right to sue.

Questions People Often Ask

•  Can autoimmune diseases qualify? Yes, if symptoms create functional limitations preventing consistent work.
•  What happens if my claim is denied? You generally have 180 days to submit an administrative appeal with supporting evidence.
•  Do you need a lawyer? Not necessarily for the initial claim, but representation during the appeal stage is critical because that evidence determines the final record for court.
