What happens when you file for SSDI

When you file for SSDI, you are asking Social Security to review your medical records and work history to decide whether your condition prevents you from working. The process takes three to six months on average, though some cases take longer. Social Security will ask you detailed questions about your condition, your past jobs, and what you can and cannot do physically and mentally.

You do not need a lawyer to file, but you will need to gather medical evidence—test results, doctor's notes, hospital records—that shows how your condition limits your ability to work. Social Security will also request records from your doctors directly. If you are approved, your first payment arrives the month after your waiting period ends, which is five months from the date your disability began.

Where and how to file your claim

You have three ways to file: online at ssa.gov, by phone at 1-800-772-1213 (TTY 1-800-325-0778), or in person at your local Social Security office. Filing online is usually the fastest route because you can work at your own pace and save your progress. The online form is called the iClaim, and it walks you through each question step by step.

If you file by phone, a Social Security representative will ask you the same questions and fill out the form for you. This takes about 30 to 45 minutes. If you file in person, bring your Social Security card, birth certificate, and proof of citizenship or legal residency. You can find your local office at ssa.gov/locator or by calling the main number.

Whichever method you choose, Social Security will send you a confirmation letter with your claim number. Keep this number—you will use it to check the status of your case and to communicate with Social Security about your claim.

Medical records and evidence you will need

Social Security needs medical evidence to prove your condition is severe enough to prevent you from working. This means records from doctors who have actually examined you, not just your own description of your symptoms. Gather records from the past three months if possible, though older records help too if they show your condition has been ongoing.

The types of records that matter most are: test results (MRI, X-ray, blood work), hospital discharge summaries, doctor's notes from office visits, mental health treatment records if you have them, and any reports from specialists. If you have had surgery or been hospitalized, those records are especially important. You do not have to collect everything yourself—Social Security can request records from your doctors—but providing them upfront speeds up the process.

If you do not have recent medical treatment, Social Security may schedule you for a consultative examination with a doctor they choose and pay for. This is free to you. The exam is not meant to treat you; it is meant to create a medical record that Social Security can use to make a decision.

Work history and what you can do

Social Security will ask about every job you have held in the past 15 years. For each job, they want to know the job title, the dates you worked, what you did day-to-day, and how much you earned. They use this information to understand what kind of work you have done and whether your condition prevents you from doing similar work in the future.

You will also be asked detailed questions about your daily activities: Can you lift things? How long can you sit or stand? Can you concentrate on a task? Do you have pain or fatigue that limits you? Can you follow instructions? Do you have memory problems? These questions matter because Social Security uses your answers to decide whether you can do any job that exists in the economy, not just the job you used to do.

Be honest and specific. If you say you cannot sit for more than 30 minutes, Social Security will use that fact. If you say you have good days and bad days, explain what that means—how many bad days per week, what you cannot do on those days. Vague answers like "I am in a lot of pain" are less useful than "I have sharp pain in my lower back when I stand for more than 20 minutes."

The timeline from filing to decision

After you file, Social Security sends your claim to a Disability information Services office in your state. This office is run by your state but follows federal rules. They review your medical records, your work history, and your answers to the questions you provided. This review takes one to three months.

Once the state office makes a decision, Social Security sends you a letter. If you are approved, the letter tells you when your benefits start and how much you will receive each month. If you are denied, the letter explains the reason—usually that your condition is not severe enough, or that you can still do some kind of work.

If you are denied, you have 60 days from the date of the letter to file an appeal. Most people who appeal with new medical evidence—especially evidence showing your condition has worsened—are eventually approved. You do not lose anything by appealing; the clock does not restart, and if you win on appeal, you receive back pay to the date you originally filed.

Working with a representative

You can hire a lawyer or a non-lawyer representative (called a certified advocate or accredited representative) to help with your claim. They can gather medical records, prepare your case, and represent you at a hearing if you appeal. The important thing to know is that they are paid only if you win, and only from your back pay—never from your ongoing monthly benefit.

The fee is set by law: up to 25 percent of your back pay, or $6,000, whichever is less. You do not pay anything upfront. If you want to work with a representative, ask them to sign a fee agreement with you before they start work. You can find accredited representatives through the Social Security website or through disability advocacy organizations in your state.

Many people file on their own and do fine. Others find that having someone help them gather records and explain their condition makes the difference between approval and denial. If your case is complex—multiple conditions, gaps in medical treatment, or a previous denial—a representative can be especially helpful.

What happens after you are approved

Once you are approved, Social Security sends you a notice with your benefit amount and your start date. Your first payment arrives the month after your five-month waiting period ends. For example, if your disability began in January, your waiting period ends in May, and your first payment arrives in June.

You will also become covered by Medicare after you have been on SSDI for 24 months. This means you get hospital insurance (Part A) and can buy medical insurance (Part B) at no cost. If you have low income, you may also be covered by Medicaid, which varies by state.

Once you are receiving benefits, you must report certain changes to Social Security: if you start working, if your medical condition improves significantly, if you move, or if your contact information changes. You do not lose benefits when ready if you work—there are work incentives that let you test your ability to work without losing your entire benefit—but you must report the work.

Common reasons claims are denied

Social Security denies claims for several reasons. The most common is insufficient medical evidence—your records do not show a severe condition, or there are gaps in your treatment. Another common reason is that Social Security believes you can still do some kind of work, even if not your past job. A third reason is that your condition has not lasted or is not expected to last 12 months or longer.

If you are denied, read the letter carefully. It will tell you the specific reason. If the reason is lack of medical evidence, get more treatment and file an appeal with new records. If the reason is that Social Security thinks you can work, gather statements from your doctors explaining why you cannot, or describe in detail what you tried to do and why you could not continue. If the reason is duration, ask your doctor whether your condition is expected to last at least 12 months and get that in writing.

Frequently Asked Questions

Can I file for SSDI if I have never worked?

No. SSDI is based on your work history and the taxes you or your family have paid into Social Security. If you have never worked, you may be able to file for Supplemental Security Income (SSI) instead, which is a needs-based program. SSI has different rules and lower income and resource limits.

How much back pay will I receive if I am approved?

You receive back pay from the date your disability began, minus the five-month waiting period. If you filed when ready when you became disabled, you receive back pay for the time between the end of your waiting period and the month you are approved. If you filed months later, your back pay is smaller because the waiting period starts from the date you became disabled, not the date you filed.

What if I disagree with the decision letter?

You have 60 days from the date on the letter to file an appeal. The first level of appeal is called reconsideration, where a different examiner reviews your case. If you are denied again, you can request a hearing before an Administrative Law Judge. At a hearing, you can present new evidence and testify about your condition.

Do I need a doctor's statement saying I cannot work?

A clear statement from your doctor helps, but Social Security makes the final decision based on all your medical records, not just one letter. The statement should explain specifically what you cannot do—not just "patient is disabled"—and should reference your test results and examination findings.

Can I work while my claim is being decided?

Yes. Working while your claim is pending does not hurt your case. However, if you earn more than $1,550 per month (in 2024), Social Security may use that as evidence that you can work. Keep records of any work you do and any problems you had doing it, in case you need to explain it later.
