The Basic Steps to File for SSDI
To claim SSDI, you file an process with the Social Security Administration (SSA) using one of three routes: online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office. The online process takes about 15 to 20 minutes if you have your documents ready. You will need your Social Security number, birth certificate, medical records, work history, and a list of doctors and hospitals that have treated you.
After you submit your process, the SSA sends it to your state's Disability information Services (DDS) office, which is the agency that actually decides whether you meet the medical requirements. You do not hear back when ready — the SSA typically takes 3 to 6 months to make an initial decision, though some cases take longer if your medical evidence is incomplete or if the DDS needs more information from your doctors.
The SSA will contact you by mail or phone if they need additional documents or clarification. It is your responsibility to respond within the timeframe they give you, usually 10 business days. If you miss the important date, your process may be denied, though you can request reconsideration.
Key Takeaways
- You can file online at ssa.gov, by phone at 1-800-772-1213, or at your local Social Security office, and the online method is usually fastest.
- The SSA will ask for your Social Security number, birth certificate, medical records from all doctors who have treated you, and a complete work history for the past 15 years.
- The decision process takes 3 to 6 months on average, and the SSA will contact you if they need more information — you must respond within the important date they provide.
- If your process is denied, you have the right to request reconsideration within 60 days, which sends your case to a different reviewer at the DDS.
- You can file a new process at any time, but filing again without new medical evidence or changed circumstances will likely result in the same decision.
What Documents You Need Before You File
Gather these documents before you start your process. You will need your original birth certificate or a certified copy, your Social Security card or a record of your number, and proof of U.S. citizenship or legal residency (a passport, naturalization papers, or a green card). If you are not a U.S. citizen, you must have been a lawful resident for at least 5 consecutive years.
Bring medical records from every doctor, hospital, clinic, or mental health provider who has treated you for your condition. Include the names, addresses, and phone numbers of all these providers. The SSA will request records directly from them, but having this list ready speeds up the process. If you have had recent surgeries, imaging tests (X-rays, MRIs, CT scans), lab work, or psychiatric evaluations, make sure those records are included.
You will also need your work history for the past 15 years, including the names of employers, dates you worked, and the type of work you did. If you are self-employed, bring tax returns for the past 2 years. Have your bank account information ready if you want your payments deposited directly, and the name and phone number of a person the SSA can contact if they cannot reach you.
Filing Online, by Phone, or In Person
Online filing through ssa.gov/applyfordisability is the fastest route. You create an account, fill out the process form, and upload documents or provide your doctors' contact information so the SSA can request records directly. You receive a confirmation number when ready and can check the status of your process online anytime. This method works best if you have all your documents ready and your medical history is straightforward.
Phone filing at 1-800-772-1213 (TTY 1-800-325-0778) takes about 30 to 45 minutes. A representative asks you questions and fills out the process while you are on the call. You receive a confirmation number at the end. This method is useful if you need help understanding questions or if you do not have internet access, but wait times can be long, especially early in the week.
In-person filing at your local Social Security office gives you the chance to ask questions face-to-face and hand over documents directly. You can find your nearest office at ssa.gov/locator. Call ahead to ask if you need an appointment, as some offices require them. Bring all your documents with you; do not rely on mailing them later.
What Happens After You File
Once your process reaches the DDS, a disability examiner and a medical consultant review your medical records to see whether your condition meets the SSA's definition of disability. The SSA defines disability as a condition that prevents you from doing substantial work and is expected to last at least 12 months or result in death. The DDS does not decide based on your word alone — they base the decision on medical evidence in your records.
If the DDS needs more information, they will order a consultative examination (CE) — a medical exam paid for by the SSA. You will receive a notice in the mail telling you where and when to go. This exam is separate from your regular doctor visits and is conducted by a doctor chosen by the SSA, not your own physician. You must attend the exam; missing it without a good reason can result in a denial.
The DDS will mail you a decision letter explaining whether you were approved or denied. If approved, the letter tells you when your benefits begin and how much you will receive each month. If denied, the letter explains the reason and tells you how to request reconsideration.
Understanding an Initial Denial and Reconsideration
If your process is denied, you have 60 days from the date on the decision letter to request reconsideration. This is a free process that sends your case to a different examiner and medical consultant at the DDS. You can submit new medical evidence, new statements from your doctors, or additional information about how your condition affects your ability to work. Many people are approved on reconsideration because they provide more detailed medical records or clearer explanations of their limitations.
To request reconsideration, complete Form SSA-561 (Request for Reconsideration) and mail it to the address on your denial letter, or submit it online through your ssa.gov account. Include any new medical records, letters from your doctors, or other evidence that supports your claim. The reconsideration process takes another 3 to 6 months.
If you are denied again after reconsideration, you can request a hearing before an Administrative Law Judge (ALJ). This is a more formal process where you can present evidence and testimony. You have 60 days from the date of the reconsideration denial to request a hearing. Many people hire a disability representative or attorney at this stage, though it is not required.
Timeline From Filing to First Payment
| Stage | Typical Duration | What Happens |
|---|---|---|
| process review at DDS | 3 to 6 months | Examiner and medical consultant review your records; SSA may order a consultative exam |
| Initial decision mailed | Same day as approval | You receive approval or denial letter with effective date of benefits (if approved) |
| First payment | 1 to 2 months after approval | Payment arrives by direct deposit or check; amount depends on your work history |
| Reconsideration (if denied) | 3 to 6 months | New examiner reviews your case and any new evidence you submit |
| Hearing before ALJ (if denied again) | 6 to 12 months | You present evidence and testimony; judge issues written decision |
What Medical Evidence the SSA Needs
The SSA does not make a disability decision based on your description of your symptoms alone. They need objective medical evidence — test results, imaging, lab work, and detailed notes from your doctors that show what your condition is and how it limits your ability to work. For physical conditions, this means X-rays, MRIs, blood tests, or surgical reports. For mental health conditions, this means psychiatric or psychological evaluations, treatment notes from a therapist or psychiatrist, and information about medications you take.
Your medical records should show that you have been treated consistently by a doctor for your condition. If you have not seen a doctor in months or years, the SSA will assume your condition has improved. If you cannot afford regular medical care, tell the SSA — they may order a consultative exam at no cost to you. However, lack of treatment can make approval harder, so seek care through a community health center, hospital clinic, or mental health provider if you cannot afford a private doctor.
Bring letters from your doctors that specifically describe how your condition affects your ability to sit, stand, walk, lift, concentrate, remember instructions, or interact with others — whatever limitations are relevant to your condition. A generic letter saying "this patient is disabled" does not help. A detailed letter explaining that you cannot sit for more than 30 minutes without severe pain, or that you have panic attacks that prevent you from working around other people, is much more useful.
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 have paid into Social Security. You must have earned enough work credits — typically at least 20 credits in the 10 years before you became disabled, though the requirement varies by age. If you have never worked or have very limited work history, you may be able to file for Supplemental Security Income (SSI) instead, which is a needs-based program with different rules.
What if I am still working but making very little money?
You can file for SSDI while working. The SSA defines "substantial gainful activity" as earning more than a certain amount per month — in 2024, that threshold is $1,550 for non-blind individuals, though this amount changes yearly. If you earn less than this amount, you can still be found disabled. If you earn more, the SSA will likely deny your claim, though exceptions exist for certain work incentive programs.
Do I need a lawyer to file for SSDI?
No. You can file on your own and many people are approved without legal help. However, if your process is denied and you request a hearing before a judge, having a representative can improve your chances. Disability representatives and attorneys charge a fee only if you win, and the fee is capped at 25 percent of your back pay (the money owed from your effective date to your approval date), up to $7,200.
What if I disagree with the medical evidence the SSA used?
You can submit a statement explaining why you disagree and provide additional medical records or a letter from your doctor. During reconsideration or a hearing, you can present this evidence and explain your position. If you believe the SSA's consultative exam was inaccurate, you can request that your own doctor provide a detailed rebuttal letter describing why the exam findings do not match your actual condition.
Can I file for SSDI on behalf of someone else?
If the person is a minor or is unable to manage their own affairs, you can file as their representative or legal guardian. You will need to provide proof of guardianship or power of attorney. If the person is an adult capable of understanding the process, they must sign the process themselves, though you can help them gather documents and submit it.
