Long-Term Disability and SSDI: Why Your Insurer May Ask You to Apply

Updated November 2026

The short answer: Many long-term disability (LTD) insurance policies through work require you to apply for Social Security Disability Insurance (SSDI), and some require you to appeal if SSDI says no. The reason is usually an "offset": if SSDI starts paying, the insurer lowers its own payment. Your policy wording decides what applies to you, so read it closely.

General information only, not legal, financial, or medical advice.

If you are in your 50s or early 60s, out of work because of your health, and getting LTD checks, a letter from your insurer telling you to apply for SSDI can be confusing. You already have disability coverage. Why apply for another kind? This article explains how the two fit together in plain words, and what to get organized now.

LTD and SSDI are two different things

LTD insurance is a private policy, usually through an employer. It is a contract with an insurance company, and the insurer decides your claim under the terms of that policy.

SSDI is a federal program. It is based on your work history and the Social Security taxes you paid. To be eligible, you generally need enough work credits and a health condition that keeps you from substantial work and has lasted, or is expected to last, at least 12 months.

Because they are separate, one can say yes while the other says no. Getting LTD does not mean SSDI will follow, and an SSDI denial does not by itself end your LTD.

Why your insurer wants you to apply

Most group LTD policies include what is called an offset. If you start getting SSDI, the insurer subtracts that amount from what it pays you. In many cases your total monthly income stays about the same. What changes is who is paying it.

That is why many policies say you must apply for Social Security disability, and some say you must keep appealing if you are turned down. Some insurers offer to help with the SSDI application or refer you to a company that does.

Some policies go a step further. If you do not apply when asked, the insurer may lower your LTD payment by an estimate of what SSDI might have paid. Look for the "other income" or "Social Security" section of your policy, or ask the insurer to show you where the rule is written.

Does LTD lower your SSDI?

Generally, no. Private pensions and private insurance benefits do not reduce SSDI. Workers' compensation and some public disability benefits are different and can affect SSDI. With LTD, the offset usually runs the other way: SSDI can lower the LTD payment, not the reverse.

Why SSDI can still matter to you

If the money mostly comes out even, you might wonder why it matters. Here are a few things people in their 50s and early 60s often weigh:

• LTD may not last as long as you expect. Many policies pay if you cannot do your own job for a first period, often 24 months. After that, the test often changes to whether you can do any job that fits your training and experience. Some people lose LTD at that point.
• Medicare. People on SSDI generally become eligible for Medicare after 24 months of SSDI. LTD does not come with health coverage.
• SSDI does not depend on one company. It is a federal benefit, not a private contract.

None of this means SSDI is right for everyone or that a claim will succeed. It is simply why the question deserves a careful look.

Back pay and paying the insurer back

SSDI decisions can take months. If SSDI later pays back pay for months when your insurer was already paying full LTD, many policies let the insurer recover that overlap. This is often called an overpayment. Some insurers take it out of future LTD checks. Others ask for one payment.

This surprises a lot of people. A few simple habits can help:

• Read your policy's offset and overpayment sections before any SSDI decision arrives.
• Keep every letter from your insurer and every letter about your SSDI claim.
• Do not spend SSDI back pay until you know whether your insurer will ask for part of it.
• Ask the insurer to put its numbers in writing.

The two look at your health differently

Your insurer's yes does not carry over to SSDI. SSDI uses its own federal rules. It looks at your medical records, how your conditions limit what you can do day to day, and, for people 50 and older, your age, education, and past work. Our article on how age is considered after 50 explains why the picture can look different in your 50s and early 60s. For a bigger overview, see our SSDI after 50 guide.

So it helps to have clear, honest information ready, even if you already went through this with your insurer.

What to get organized now

You may have already given your insurer a lot of paperwork. Much of it overlaps with what helps an SSDI claim. Start one folder with:

1. Your LTD policy or plan booklet, plus every letter from the insurer, including the letter that started your benefits.
2. A list of every doctor, clinic, and hospital, with addresses and rough dates. Our post on why doctor visits matter explains why steady care helps.
3. Your medications and side effects, in your own words.
4. Notes on your daily limits. A symptom journal makes this easier. Use specific examples, like "I can sit about 20 minutes before I need to stand."
5. Your work history for the last several years, with what each job asked of you. See how work history is used.
6. Your last day of work and why you stopped. If your job ended in a layoff, our post on applying after being laid off covers that situation.

Keep what you tell your insurer and what you say in an SSDI claim honest and consistent. Differences between the two can raise questions.

Common mistakes

• Waiting until LTD ends. SSDI decisions take time, and a gap in income can be hard.
• Assuming LTD means SSDI. The rules are different.
• Missing an insurer deadline. A deadline in your policy can affect your LTD checks.
• Skipping the overpayment section. Back pay surprises are common.
• Not asking who a helper works for. If your insurer refers you to someone for SSDI help, it is fine to ask who they represent and how they are paid. You can also compare ways to get help applying for SSDI.

Where Disability Prep fits

Disability Prep is an independent preparation service for adults considering SSDI. We are not a law firm, not an insurance company, and not affiliated with or endorsed by the Social Security Administration. Only Social Security decides SSDI claims, and we cannot promise any outcome. Our screening can help you see where you stand and, only if you agree, connect you with a participating disability advocate or representative.

Frequently asked questions

Do I have to apply for SSDI if I have long-term disability insurance?
Many group LTD policies require it, and some also require you to appeal if SSDI says no. Your policy wording decides. Look for the "other income" or "Social Security" section, or ask your insurer to show you the rule in writing.

Will my LTD payment go down if I get SSDI?
Often, yes. Most group LTD policies have an offset, so the insurer subtracts your SSDI amount from its payment. Your total is often about the same. What changes is who pays it.

Does long-term disability reduce my SSDI?
Generally, no. Private insurance benefits do not reduce SSDI. Workers' compensation and some public disability benefits are different.

Will I have to pay my insurer back if I get SSDI back pay?
Many policies let the insurer recover LTD it paid for months that SSDI back pay also covers. Read your policy's overpayment section and ask the insurer for its numbers in writing before you spend any back pay.

If my insurer says I am disabled, will SSDI agree?
Not necessarily. SSDI uses its own federal rules and looks at your records, your daily limits, and, for people 50 and older, your age, education, and past work. Each decision is separate.

Can my insurer help me apply for SSDI?
Some insurers offer help or refer you to a company that helps with SSDI claims. It is fine to ask who that helper represents and how they are paid, and to compare your options.
