What long-term disability is and how it differs from SSDI

Long-term disability (LTD) is an insurance benefit you receive through your employer or buy privately. It replaces part of your income if you cannot work due to illness or injury for an extended period—usually longer than three to six months. SSDI (Social Security Disability Insurance) is different: it is a federal program run by Social Security that pays benefits based on your work history and the severity of your condition, with no time limit as long as you remain disabled.

The key difference is the source and the rules. Your employer's LTD plan is a contract between you and the insurance company. SSDI is a government program with its own medical standards and work-credit requirements. You can have both at the same time, though SSDI payments are usually reduced by the amount you receive from LTD.

Many people confuse the two because both replace lost wages and both require proof that you cannot work. But they operate independently, have different approval processes, and pay from different sources.

Key Takeaways

  • Long-term disability is insurance through your employer or a private policy, while SSDI is a federal program—they are separate systems with different rules.
  • Most employer LTD plans require you to be unable to work for 90 days or more before benefits begin, and they typically replace 50 to 70 percent of your salary.
  • To receive LTD, you must have an active policy at the time you become disabled, and you must provide medical documentation proving you cannot perform your job.
  • LTD benefits usually last until you reach retirement age, return to work, or exhaust the benefit period set by your plan—SSDI has no time limit if you remain disabled.
  • If you receive both LTD and SSDI, your SSDI payment is reduced by the LTD amount, a process called offset.

Whether you have an employer plan and what it covers

The first step is to find out whether your employer offers long-term disability insurance. Check your employee handbook, benefits summary, or ask your HR department directly. Not all employers provide LTD; it is most common at larger companies and in certain industries like healthcare, education, and finance.

If your employer does offer LTD, review your plan documents to learn the specifics: how long you must be unable to work before benefits start (the elimination period, usually 90 days), what percentage of your salary is replaced (typically 50 to 70 percent), and how long benefits last. Some plans pay until age 65, others for a set number of years like five or ten.

If you do not have employer coverage, you can purchase an individual LTD policy from an insurance company, though these are more expensive and have stricter medical requirements. Self-employed people and gig workers often buy individual policies.

Medical proof that you cannot work

Long-term disability requires medical documentation showing you cannot perform your job. This is not the same as having a diagnosis—the insurance company needs evidence that your condition prevents you from working, not just that you are sick.

You will need records from your doctor or specialist that describe your symptoms, limitations, and how they affect your ability to work. The insurance company will ask your doctor specific questions: Can you sit for eight hours? Can you lift objects? Can you concentrate? Can you travel? Your doctor's answers to these questions matter more than the diagnosis itself.

If your condition is serious enough, the insurance company may send you to an independent medical examiner for a second opinion. This is routine and does not mean they doubt you—it is part of how they verify claims.

The waiting period before benefits begin

Most employer LTD plans have an elimination period of 90 days. This means you must be unable to work for 90 consecutive days before the insurance company begins paying benefits. During this time, you may be able to use sick leave, short-term disability, or unpaid leave, depending on your employer's policies.

Some plans have shorter elimination periods (30 or 60 days) or longer ones (180 days). Check your plan documents to know exactly how long you must wait. The elimination period is a cost-control measure for the insurance company and is standard across the industry.

Once the elimination period ends and your claim is approved, benefits typically begin within two to four weeks. If your claim is denied, you have the right to appeal, though the process varies by plan and insurance company.

How much you receive and for how long

Long-term disability typically replaces 50 to 70 percent of your gross monthly salary, up to a maximum amount set by your plan. If you earn $5,000 per month and your plan pays 60 percent, you would receive $3,000 per month (before taxes). Some plans cap the benefit at a specific dollar amount, like $5,000 per month, regardless of your salary.

The length of time you receive benefits depends on your plan. Common options are: benefits until age 65, benefits for five years, benefits for ten years, or benefits for the duration of your disability. Read your plan documents to know which applies to you.

If you return to work part-time or your condition improves, your benefits may be reduced or stopped. Some plans offer a return-to-work benefit that pays a partial amount while you gradually increase your hours, but this varies widely.

How SSDI and long-term disability interact

If you receive both LTD and SSDI, Social Security will reduce your SSDI payment by the amount you receive from LTD. This is called offset. For example, if your SSDI benefit would be $2,000 per month and you receive $1,500 from LTD, Social Security pays you $500.

This offset exists because both programs are designed to replace lost income, and the government does not want you to receive more than you would have earned while working. You still receive the full amount—it just comes from different sources.

You can explore for SSDI while receiving LTD. In fact, many people do, because SSDI has no time limit and LTD eventually ends. If you are approved for SSDI before your LTD benefits expire, the offset begins when ready.

What happens if your claim is denied

If your LTD claim is denied, the insurance company must provide a reason in writing. Common reasons include: insufficient medical evidence that you cannot work, a pre-existing condition exclusion in your plan, or a lapse in coverage (you were not enrolled when you became disabled).

You have the right to appeal a denial. The appeal process is outlined in your plan documents and typically involves submitting additional medical evidence or a written statement explaining why you believe you should receive benefits. Appeals can take several weeks to several months.

If your appeal is denied, you may be able to file a lawsuit against the insurance company, though this is expensive and requires an attorney. Some people pursue SSDI as an alternative if LTD is denied, since SSDI has different medical standards and approval criteria.

Frequently Asked Questions

Can I receive long-term disability if I was not enrolled when I became disabled?

No. You must have an active LTD policy at the time your disability begins. If you were not enrolled or your coverage had lapsed, you cannot file a claim. This is why it is important to enroll in employer LTD when you are first offered it.

Does long-term disability cover mental health conditions?

Most plans do cover mental health conditions like depression and anxiety, but they often have stricter requirements and shorter benefit periods than physical conditions. Some plans limit mental health benefits to two years. Check your plan documents for the specific terms.

What if I can work part-time but not full-time?

Some LTD plans pay a reduced benefit if you work part-time and earn less than you did before. Others require you to be completely unable to work. A few offer a return-to-work benefit that pays a partial amount while you gradually increase your hours. Review your plan to see which applies.

How long does it take to get approved for long-term disability?

After your elimination period ends and you submit your claim with medical documentation, approval typically takes two to four weeks. If the insurance company requests additional information from your doctor, it may take longer. Denials and appeals can extend the timeline significantly.

Can I work while receiving long-term disability?

Most plans require you to be unable to work to receive full benefits. If you work and earn income, your benefits are reduced or stopped. Some plans allow part-time work with a reduced benefit, but this varies. Contact your insurance company or review your plan to understand the work restrictions.
