Most people expect a checklist of approved diagnoses. Long-term disability does not work that way. Whether you have an employer-sponsored group plan (typically governed by the federal ERISA law) or a private policy you bought yourself, eligibility turns on a single question: does your condition stop you from working at the level your policy requires? A diagnosis by itself is never enough — the insurer wants objective medical evidence showing how your symptoms limit what you can actually do.
That said, certain conditions come up again and again because they tend to be serious and long-lasting.
Conditions that commonly qualify
- Musculoskeletal disorders — degenerative disc disease, chronic back and neck injuries, severe arthritis, and failed spinal surgeries.
- Neurological conditions — multiple sclerosis, Parkinson’s disease, epilepsy, stroke, and traumatic brain injury.
- Cancer — during active treatment and recovery, and where lasting effects remain.
- Cardiovascular and respiratory disease — heart failure, COPD, and serious limitations after a cardiac event.
- Mental health conditions — major depression, bipolar disorder, severe anxiety, and PTSD (often subject to a 24-month policy limit).
- Autoimmune and chronic illness — lupus, rheumatoid arthritis, fibromyalgia, and chronic fatigue syndrome.
- Diabetes and its complications — neuropathy, vision loss, and related organ damage.
“Own occupation” vs. “any occupation” — the rule that decides your claim
The toughest part of most policies is the definition of disability itself. Many plans pay benefits for an initial period (commonly 24 months) if you cannot perform your own occupation. After that, the standard often shifts to any occupation — meaning you must be unable to do any job your training, education, and experience could support. A condition that clearly qualified you in year one can be denied in year three under the stricter standard, so reading your policy’s exact language matters.
What actually wins a claim: documentation
The condition is only half the battle; approvals turn on proof. Strengthen your claim with consistent treatment records, specialist evaluations, objective testing (imaging, lab work, functional capacity exams), and clear statements from your doctors connecting your symptoms to specific work limitations. Gaps in treatment, vague records, or activity that appears to contradict your reported limits are among the most common reasons insurers deny otherwise valid claims.
If your claim is denied
A denial is not the end. Group LTD plans under ERISA generally require you to file an administrative appeal — usually within 180 days — before you can take the matter to court, and the appeal record you build is typically the only evidence a judge will later consider. Because outcomes depend heavily on the policy language and the medical record, every case is different and prior results do not guarantee future ones. If you are facing a denial, get the policy reviewed before the appeal deadline passes. For the full picture, start with our Long-Term Disability hub and the related questions below.
