Long-term disability covers conditions that keep you from working for months or longer

Long-term disability insurance at work pays part of your salary when you cannot do your job because of illness or injury. The conditions that count are those expected to last at least 90 days — sometimes longer, depending on your plan. Your employer's plan document lists which conditions are covered and which are not.

Unlike Social Security Disability Insurance (SSDI), which requires a condition to last at least 12 months or result in death, long-term disability plans often have their own waiting periods and their own definitions of disability. A condition that qualifies for one does not automatically may have access to for the other.

The key question is not whether you have a serious condition — it is whether that condition prevents you from performing the duties of your specific job. An accountant with a broken arm might may have access to; a surgeon with the same break might not.

Key Takeaways

  • Long-term disability covers conditions lasting roughly 90 days or more that prevent you from doing your job, as defined by your employer's plan.
  • Your plan document, not a doctor or your employer, determines what counts — some plans cover mental health conditions and some do not.
  • You must usually be unable to work for 30 to 90 days (the waiting period) before benefits begin, and you must provide medical documentation from your doctor.
  • The definition of disability in your plan may be stricter than Social Security's definition, so a condition that qualifies for SSDI might not may have access to for your work plan.
  • If your employer does not offer long-term disability, you can purchase individual disability insurance, though it is more expensive and has stricter underwriting.

How your employer's plan defines disability

Every long-term disability plan has a written definition of what counts as disabled. Most use one of two approaches: the "own occupation" definition or the "any occupation" definition.

Under own occupation, you are considered disabled if you cannot perform the duties of your specific job — the one you held when you became disabled. A pianist who loses hand function qualifies even if they could theoretically work as a consultant. This definition is more generous to the worker and is usually found in plans for higher-paid professionals.

Under any occupation, you are considered disabled only if you cannot perform any job you are reasonably suited for by training, education, or experience. The same pianist would not may have access to if the plan determined they could work in administration or teaching. This definition is more common in employer plans and is stricter.

Your plan document spells out which definition applies and when it switches. Some plans use own occupation for the first two years, then switch to any occupation. Read your Summary Plan Description (SPD) — your employer must provide this for free — to know which rule governs your claim.

Medical conditions commonly covered

Long-term disability plans typically cover conditions in these categories, though your specific plan may exclude some:

  • Musculoskeletal injuries and disorders — back injuries, torn ligaments, arthritis, carpal tunnel syndrome
  • Cancer and other serious illnesses — including treatment recovery time
  • Heart disease and stroke
  • Neurological conditions — multiple sclerosis, Parkinson's disease, traumatic brain injury
  • Mental health conditions — depression, anxiety, bipolar disorder — though some plans limit these to 12 or 24 months of benefits
  • Pregnancy complications and recovery from childbirth
  • Organ transplant and recovery
  • Respiratory conditions — COPD, severe asthma

Having a diagnosis from this list does not may provide coverage. Your plan must also determine that the condition prevents you from working under its own occupation or any occupation definition. A person with depression might may have access to if it prevents them from functioning at work; another person with the same diagnosis might not, depending on severity and the plan's assessment.

What your plan will ask for in medical proof

When you file a claim, your plan will request medical documentation. This is not a one-time submission — plans often request updated reports every 30 to 90 days while you receive benefits.

Typical documentation includes: a statement from your treating physician describing your diagnosis, the date the condition began, the treatment you are receiving, your functional limitations (what you cannot do), and the expected duration of disability. Some plans ask for specific forms filled out by your doctor. Others accept a letter from your physician.

The plan may also send you to an independent medical examination (IME) with a doctor of their choosing. This doctor will review your medical records and examine you to verify the claim. You do not pay for this examination — the plan does — but you have the right to bring your own doctor's records and to request a copy of the IME report.

If your condition improves, your plan will ask for updated medical information. If you return to any form of work, you must report it, as it may reduce or end your benefits.

The waiting period before benefits start

Most long-term disability plans have a waiting period (also called an elimination period) of 30, 60, or 90 days. This means you must be unable to work for that length of time before the plan begins paying you.

During the waiting period, you typically use paid time off — sick leave, vacation, short-term disability if your employer offers it — to cover your income. Once the waiting period ends and the plan approves your claim, benefits usually begin retroactively to the first day you were disabled, not the first day you applied.

The length of the waiting period affects the cost of the plan to your employer. Longer waiting periods mean lower premiums, so employers often choose 90 days to reduce their costs. Check your plan document or ask your benefits administrator what your specific waiting period is.

How much you receive and for how long

Long-term disability plans typically replace 50 to 70 percent of your gross salary, up to a monthly maximum. The exact amount depends on your plan. Some plans also coordinate with Social Security — if you receive SSDI, your long-term disability benefit is reduced by the amount you receive from Social Security.

The length of time you can receive benefits varies widely. Some plans pay until age 65, others for two years, others for five years. A few cover you until you die or recover. Your plan document states the benefit period.

If you return to work part-time or at a lower salary, some plans offer partial disability benefits that make up part of the income difference. This encourages people to return to work gradually. Other plans do not offer partial benefits — you either may have access to or you do not.

Conditions and situations that may not be covered

Most plans exclude or limit coverage for:

  • Conditions caused by alcohol or drug use
  • Injuries from illegal activity
  • Self-inflicted injuries
  • Pregnancy and childbirth (though complications are usually covered)
  • Mental health conditions (some plans cover these; others do not, or limit them to 12 months)
  • Back injuries without objective medical findings (some plans require imaging or nerve testing)
  • Conditions you had before you enrolled in the plan (pre-existing condition exclusions)

Pre-existing condition exclusions typically last 12 months from your enrollment date. If you had a condition before you joined the plan and it disables you within that 12-month window, the plan may not cover it. After 12 months, the exclusion usually expires.

Read your plan's exclusions section carefully. If a condition you have is listed, ask your benefits administrator whether it is fully excluded or whether exceptions explore.

If your employer does not offer long-term disability

Not all employers provide long-term disability insurance. If yours does not, you can purchase an individual disability policy on your own, though it is more expensive and requires medical underwriting. An insurance company will review your health history and may deny coverage or charge higher premiums if you have pre-existing conditions.

Individual policies also typically have longer waiting periods — 90 days or more — and lower benefit amounts than employer plans. However, they remain in force if you change jobs, whereas employer coverage ends when you leave.

If you become disabled and have no long-term disability insurance, your options are limited to savings, family support, or explore for Social Security Disability Insurance (SSDI), which has a five-month waiting period and a much stricter definition of disability.

Frequently Asked Questions

Does my long-term disability plan cover the same conditions as Social Security Disability?

No. Social Security requires that your condition last at least 12 months or result in death and that you be unable to do any substantial work. Long-term disability plans have their own definitions — some stricter, some less strict — and their own waiting periods. A condition that qualifies for one program may not may have access to for the other.

What happens if my doctor says I cannot work but the plan's doctor disagrees?

The plan will make the final decision based on its own medical review. If you disagree with a denial, you have the right to appeal. Gather additional medical records, statements from your treating physician, and any other evidence that supports your claim. Many plans require an appeal within 180 days of the denial.

Can I work part-time while receiving long-term disability?

It depends on your plan. Some plans allow partial disability benefits if you return to part-time or reduced-income work. Others require you to be completely unable to work. Check your plan document or contact your benefits administrator before taking any work, as unreported income could result in benefit reduction or denial.

What if I improve and then get worse again?

If you return to work and then become disabled again from the same condition within a certain period (usually 12 months), many plans treat it as a continuation of the original claim rather than a new claim. If the condition is different or the gap is longer, it may be treated as a new claim with a new waiting period.

How do I know what my plan covers?

Request your Summary Plan Description (SPD) from your employer's benefits department. This document is free and required by law. It explains what is covered, the waiting period, the benefit amount, the benefit period, and how to file a claim. If you cannot find it, ask your HR department or benefits administrator directly.
