When are you entitled to long-term disability benefits? Qualifying under Social Security Disability Insurance (SSI), employer disability plans, or private insurance starts with this question: Are your medically documented limitations such that you cannot engage in full-time employment on a long-term basis (at least 12 months) or are they likely to cause death?
Your eligibility for disability benefits under SSI and other disability programs is determined by your medical documentation and the demonstrated effect of your condition on daily job activities such as standing, lifting, concentrating, and keeping pace and attendance. If you’re unsure whether you qualify for disability benefits, InPerSuit can connect you with experienced disability lawyers who will review your case at no cost to you.
How eligibility is decided
The Social Security Administration and other disability benefit providers look for a diagnosed complication, objective information, and regular treatment. Imaging results, lab findings, expert records, surgical records, treatment records and the opinion of your physician regarding certain work restrictions are considered in determining your eligibility.
In the case of Social Security, your age, education and your previous employment history are also taken into account to decide whether there are any jobs that are within your range of operation. Private disability insurance may define “disability” using your “own occupation” to decide your eligibility, or may determine eligibility more narrowly using an “any occupation” definition.
The credibility and consistency of your evidence are weighed heavily in the eligibility decision across all disability programs. Your forms, clinic notes and testimony should be telling the same story.
Common qualifying conditions
Bone and muscle injuries and chronic aches. If you live with constant pain, limited movement, or reduced physical strength, you may qualify for disability benefits. Conditions such as serious spine disorders, failed back surgery, complex regional pain syndrome, severe arthritis, major fractures, or shoulder and knee injuries can make steady work difficult or impossible.
Medical evidence showing persistent pain, loss of range of motion, limited ability to lift, stand, or walk, and the need for frequent rest breaks helps demonstrate that your symptoms significantly limit your ability to work.
Neurological conditions. Disorders that affect the brain, spinal cord, or nerves can cause serious and lasting problems with movement, coordination, and focus. Conditions such as stroke, multiple sclerosis, epilepsy, traumatic brain injury, peripheral neuropathy, Parkinson’s disease, or chronic migraine may qualify for disability benefits if they make consistent work difficult.
Medical records that show objective test results, along with ongoing symptoms like weakness, tremors, seizures, poor coordination, or cognitive difficulties, can help demonstrate that your condition prevents reliable job performance.
Heart and lung disease. Serious heart or breathing conditions can make even simple activities, like walking short distances or climbing stairs, difficult to manage on a regular basis. Conditions such as congestive heart failure, coronary artery disease, severe arrhythmias, COPD, pulmonary fibrosis, and uncontrolled asthma may qualify for disability benefits.
Medical tests that show reduced heart or lung capacity, combined with your doctor’s explanation of limits on physical exertion, exposure to irritants, or the need for frequent rest or oxygen, can provide strong support for your claim.
Inflammatory disease and autoimmune disease. Lupus, rheumatoid arthritis, inflammatory bowel disease, Sjögren’s syndrome, and other diseases often come and go, with good days and bad days that make full-time work hard to sustain. These illnesses can cause pain, fatigue, and unpredictable flare-ups that interfere with focus, attendance, and stamina.
Detailed medical records over time, including lab results, medication side effects, and fatigue or symptom logs, can help show how your condition limits your ability to maintain consistent work—even when you’re doing everything possible to manage it.
Cancer and its treatment. If you’re undergoing treatment for cancer or dealing with its long-term effects, you may qualify for disability benefits. Most cancers meet the requirements during active treatment or when complications, metastasis, or lasting side effects make steady work impossible.
Common symptoms include fatigue, nausea, pain, weakness, or difficulty concentrating during or after chemotherapy or radiation. Key evidence includes surgical and pathology reports, oncology treatment notes, and records showing how your symptoms interfere with daily functioning or reliable attendance.
Systemic illness, endocrine; renal. Chronic conditions such as diabetes accompanied by neuropathy or vision loss, chronic kidney disease, advanced liver disease, or serious blood disorders can make it difficult to maintain steady work. These illnesses significantly reduce energy, stamina, concentration, manual dexterity, and attendance.
Medical records showing lab results, specialist notes, and documented work restrictions can help demonstrate that your condition limits your ability to perform reliable, full-time work.
Major mental illness.
Conditions such as major depressive disorder, bipolar disorder, post-traumatic stress disorder (PTSD), schizophrenia, and severe anxiety disorders can qualify for disability benefits when symptoms make it difficult to maintain reliable focus, handle stress, or interact appropriately with others at work.
Medical and psychological records that show consistent treatment, ongoing symptoms, and limitations in concentration, social functioning, or attendance are important. Even with therapy and medication, these disorders can continue to interfere with consistent, full-time employment.
Not all diagnoses qualify. Having a medical diagnosis alone doesn’t automatically mean you’ll be approved for disability benefits. What matters most is how your symptoms, limitations, and medical evidence show that you can’t maintain full-time, reliable work.
The Social Security Administration and other disability benefit providers look closely at your functional abilities, not just your diagnosis. They will consider things like how long you can sit, stand, or concentrate, how often you miss work, and whether you can complete tasks consistently. The stronger and more detailed your documentation, the better your chances of demonstrating that your condition truly prevents steady employment.
How to build a stronger disability claim
Strong disability claims clearly connect your symptoms to specific work limitations. Ask your treating providers to include written opinions describing what you can realistically do. Provide evidence that describes limitations on how much you can lift, how long you can stand or sit, how often you lose focus, or how many days you’re likely to miss each month.
Tests such as Functional Capacity Evaluations, neuropsychological assessments, sleep studies, or cardiac and pulmonary stress tests can turn medical observations into measurable work restrictions. Continue following treatment, take reasonable medical advice, and record any side effects like drowsiness, dizziness, or mental fog. Keeping a short daily journal that tracks your bad days and rest time can also strengthen your case, especially when your condition fluctuates.
When to file and what to expect
You should consider filing for long-term disability benefits when it becomes clear that you’ll be unable to work for at least one year. The Social Security process has several steps which include reconsideration and a hearing. For private disability policies, you must provide timely notice and an internal appeal is often required before filing a lawsuit.
Keep in mind that denials are common but many are overturned when additional medical and functional evidence is provided during appeal. Because deadlines are strict, carefully read every letter you receive, make sure to respond to all deadlines timely, and keep copies of everything you send.
