What SSDI Is and Who Can Get It

Social Security Disability Insurance (SSDI) is a federal program that pays monthly benefits to people who have worked and paid Social Security taxes, but can no longer work because of a medical condition. The condition must be expected to last at least 12 months or result in death. You do not need to be poor to receive SSDI — it is based on your work history, not your income.

SSDI is different from Supplemental Security Income (SSI), which is a needs-based program for people with disabilities who have little or no work history. Both programs are run by the Social Security Administration, but the rules for who qualifies are different. This article focuses on SSDI.

To be found disabled under SSDI, Social Security must determine that your condition prevents you from doing any substantial work. This is a high bar. Social Security looks at whether you can do the work you did before, and if not, whether you can do any other work that exists in the national economy, considering your age, education, and work skills.

Key Takeaways

  • You must have worked and paid Social Security taxes for a certain number of quarters (usually 40 quarters total, with at least 20 in the last 10 years) to be found disabled under SSDI.
  • Your medical condition must be documented by a doctor or other medical professional and must prevent you from working for at least 12 months or result in death.
  • You can start the process by calling Social Security at 1-800-772-1213, visiting your local Social Security office, or explore online at ssa.gov.
  • The initial decision usually takes three to five months, but many people are denied on first process and must request reconsideration or a hearing before an administrative law judge.
  • A disability lawyer can represent you at any stage and typically takes a fee only if you win, capped by federal law at 25 percent of your back pay.

The Work History You Need

Social Security measures your work history in quarters of coverage. A quarter is roughly three months, and you earn one quarter of coverage for each $1,550 you earn in a year (this amount changes yearly). Most people need 40 quarters total to be found disabled under SSDI — that is roughly 10 years of work. You also need at least 20 of those quarters to fall within the last 10 years.

There are exceptions for younger workers. If you became disabled before age 24, you may need only six quarters of coverage in the three-year period before your disability began. If you became disabled between ages 24 and 31, you generally need quarters equal to half the time between age 21 and the time you became disabled.

You can check your work history by creating an account at ssa.gov and viewing your Social Security Statement. This shows the quarters you have earned and helps you know whether you meet the work requirement before you explore.

The Medical Evidence You Will Need

Social Security will not take your word that you cannot work. You must have medical evidence from a doctor, psychiatrist, nurse practitioner, physician assistant, or other licensed medical professional. The evidence should document your diagnosis, the tests or exams that support it, and how it limits what you can do physically and mentally.

Gather medical records from every doctor who has treated you for your condition. Include hospital records, lab results, imaging reports, and notes from office visits. If you see a mental health provider, include those records too. Social Security will request these records from your doctors, but having them ready speeds up the process.

If you have not seen a doctor recently, you should do so before you explore. Social Security looks for current medical evidence — records from years ago are less persuasive. If you cannot afford a doctor, look for a community health center or free clinic in your area. Some disability lawyers can refer you to doctors who understand the SSDI process.

How to Start Your process

You have three ways to explore for SSDI. The fastest is usually online at ssa.gov/applyfordisability. The process takes about 15 to 20 minutes and you can save your progress and come back to it. You will need your Social Security number, birth certificate, and information about your medical condition and doctors.

You can also call Social Security at 1-800-772-1213 (TTY 1-800-325-0778) to explore by phone. Hours are Monday through Friday, 7 a.m. to 7 p.m. your local time. Wait times are often long, especially early in the week.

A third option is to visit your local Social Security office in person. You can find the address at ssa.gov/locator. Bring your Social Security card, birth certificate, and a list of your doctors and hospitals. An office worker will help you fill out the process.

What Happens After You explore

After you submit your process, Social Security sends it to your state's Disability information Services (DDS) office. This office is part of your state government but works under federal rules. A team at DDS — usually a disability examiner and a medical or psychological consultant — reviews your medical evidence and decides whether you meet Social Security's definition of disabled.

DDS will request medical records from the doctors you listed. This can take several weeks. If your records are incomplete, DDS may ask you to see a doctor for an exam or test that Social Security pays for. You are not required to go, but refusing usually results in a denial.

The initial decision usually comes within three to five months. Social Security will mail you a letter saying you are approved, denied, or approved for a different program (such as SSI). If you are denied, the letter explains why and tells you how to request reconsideration.

What to Do If You Are Denied

Most people are denied on their first process. This does not mean you cannot get SSDI — it means you will need to go through additional steps. You have 60 days from the date on your denial letter to request reconsideration. This sends your case to a different examiner at DDS who reviews it from scratch.

If reconsideration is also denied, you can request a hearing before an administrative law judge (ALJ). This is where many people succeed. At a hearing, you can present new medical evidence, testify about how your condition affects your ability to work, and have a lawyer represent you. The wait for a hearing is usually one to two years, depending on your area.

You can request reconsideration and a hearing yourself, but a disability lawyer can significantly improve your chances. Lawyers know what evidence Social Security needs and how to present it persuasively. If you win at any stage, the lawyer's fee is taken from your back pay — the money Social Security owes you from the date you became disabled.

How Much You Will Receive

Your SSDI payment is based on your lifetime earnings record, not on how disabled you are or how much money you need. The average payment in 2024 is around $1,550 per month, but payments range widely. You can estimate your payment by viewing your Social Security Statement at ssa.gov.

Your payment starts the month after you have been disabled for five full months. So if you became disabled in January, your first payment would be in July. This five-month waiting period applies to everyone, regardless of when you explore.

Once you are approved, you continue to receive payments as long as you remain disabled and do not work above a certain level. In 2024, you can earn up to $1,550 per month and still receive full benefits (this amount changes yearly). If you earn more, your benefits are reduced or stop.

Frequently Asked Questions

Can I work while I am waiting for a decision?

Yes. You can work and earn money while your process is being reviewed. However, if you earn more than $1,550 per month (in 2024), Social Security may conclude you are not disabled. Keep your earnings low or document that your work is part-time or temporary while you recover.

What if I disagree with the medical evidence Social Security uses?

You can submit your own medical evidence at any stage — with your initial process, during reconsideration, or before a hearing. You can also ask your doctor to write a statement explaining why you cannot work. At a hearing, you can testify and your doctor can testify on your behalf.

Do I need a lawyer to get SSDI?

No, you can explore and go through reconsideration on your own. However, at a hearing before an administrative law judge, having a lawyer significantly increases your chances of winning. Lawyers are paid only if you win, so there is no upfront cost.

What is the difference between SSDI and SSI?

SSDI is based on your work history and Social Security taxes you paid. SSI is based on financial need and is available to people with disabilities who have little or no work history, or to people over 65 with low income. You may be found disabled under one program but not the other.

Can I get SSDI for a mental health condition?

Yes. Social Security recognizes many mental health conditions, including depression, anxiety, bipolar disorder, schizophrenia, and post-traumatic stress disorder. You will need medical evidence from a psychiatrist or psychologist, documentation of treatment, and evidence that the condition prevents you from working.
