The Basic Steps to File for SSDI

You can file for Social Security Disability Insurance (SSDI) in three ways: online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office. The online method is fastest — you can complete the process in one sitting without waiting for an appointment. By phone, a representative will walk you through the form, which takes 20 to 30 minutes. In person, you bring documents with you and complete the process on the spot.

The process itself asks for your name, Social Security number, date of birth, work history, medical conditions, and the names and dates of your doctors and hospitals. You do not need a lawyer to file — the Social Security Administration (SSA) accepts applications from anyone. However, if you arrive at your local office with a lawyer or representative already hired, the SSA will note that in your file, and your representative can receive updates about your case.

Filing does not cost money. The SSA charges a fee only if your case is approved and you receive back pay — the fee is 25% of the back pay or $6,000, whichever is less, and it comes out of your award, not your pocket.

Key Takeaways

  • You can file online, by phone, or in person; online is usually fastest and requires no appointment.
  • The SSA will ask for your work history, medical conditions, and the names of all doctors who have treated you in the past 12 months.
  • You do not need a lawyer to file, but you can hire one before, during, or after you submit your process.
  • The SSA charges a fee only if you win, and only from your back pay, not from your ongoing monthly benefit.
  • From the day you file to a final decision usually takes 3 to 6 months if approved, or 1 to 2 years if you must appeal.

What Documents and Information You Need Before You File

Gather these items before you start the process. You will need your Social Security number, birth certificate, and proof of citizenship or legal residency (a passport, naturalization papers, or a green card). You will also need your W-2 forms or tax returns for the past year to show your work history and earnings.

The SSA will ask for the names, addresses, and phone numbers of every doctor, hospital, and mental health provider who has treated you in the past 12 months. Write these down before you begin. Include your primary care doctor, any specialists, emergency room visits, and therapists or counselors. If you have been hospitalized, include the hospital name and the dates you were admitted and discharged.

You do not need to gather medical records yourself — the SSA will request them directly from your providers once you file. However, if you have recent test results, imaging reports, or specialist letters that clearly describe your condition, having copies on hand can speed up the process. Bring them with you if you file in person, or upload them if you file online.

Filing Online Through My Social Security

Go to ssa.gov and click "Create My Social Security Account" if you do not have one already. Once you are logged in, select "explore for Disability Benefits." The form is broken into sections: personal information, work history, medical conditions, and treatment providers. You can save your progress and return later — the SSA keeps your answers for 30 days.

When you reach the medical section, describe your condition in plain language. You do not need medical terminology. For example, write "I have severe back pain that prevents me from standing for more than 30 minutes" rather than trying to match a diagnosis code. The SSA will pull your medical records from the providers you list, so focus on describing how your condition affects your ability to work.

After you submit, you will receive a confirmation number and a receipt. The SSA will mail you a letter within 7 to 10 days confirming that your process was received. This letter includes your case number — save it. You can check the status of your process anytime by logging into your My Social Security account.

Filing by Phone or In Person

To file by phone, call 1-800-772-1213 Monday through Friday, 7 a.m. to 7 p.m. your local time. Have your Social Security number, birth certificate, and list of doctors ready. The call takes 20 to 30 minutes. At the end, the representative will mail you a confirmation letter with your case number.

To file in person, find your local Social Security office at ssa.gov/locator. Call ahead to ask if you need an appointment — some offices accept walk-ins, others require one. Bring your Social Security number, birth certificate, proof of citizenship or residency, W-2 forms or tax returns, and a list of your doctors and hospitals with dates of treatment. The office will complete the process with you and give you a receipt on the spot.

Filing in person takes longer than online or phone because you must wait for an appointment or in line, but some people prefer it because they can ask questions face-to-face and leave with a paper copy of what they submitted.

What Happens After You File

Within 3 to 5 days, the SSA sends you a letter confirming your process was received. This letter includes your case number and the name of the claims examiner assigned to your case. Keep this letter — you will need the case number if you call to check on your process or if you hire a lawyer.

The SSA then requests your medical records from every provider you listed. This step takes 2 to 4 weeks. While they wait for records, they may contact you by phone or mail to ask follow-up questions about your work history, your condition, or your treatment. Answer these questions promptly — delays in responding can slow your case.

Once the SSA has your medical records, a disability examiner reviews your file. They compare your condition against the SSA's list of impairments that automatically may have access to for benefits, and they assess whether your condition prevents you from doing any kind of work. This review takes 1 to 3 months. You will receive a letter in the mail with the decision — either approval, denial, or a request for more information.

Understanding the Decision Letter

If you are approved, the letter tells you your monthly benefit amount, the date your benefits begin, and when you will receive your first payment. SSDI benefits usually start the month after you are approved, though in some cases they can be backdated to the month you filed or to the month your condition began, whichever is later.

If you are denied, the letter explains the reason. Common reasons include: the SSA found no medical evidence of a severe condition, your condition does not meet the SSA's definition of disability, or your condition is expected to improve within 12 months. The letter also tells you that you have the right to appeal and gives you 60 days to request an appeal.

If the SSA asks for more information, the letter specifies what they need and gives you a important date — usually 10 days. Send the information promptly. If you miss the important date, your process may be denied, but you can still appeal.

When to Hire a Lawyer

You can hire a lawyer before you file, while your case is pending, or after you are denied. Many people wait until after a denial to hire one, because the fee is lower if your case is already denied — the lawyer's fee is 25% of your back pay or $6,000, whichever is less, but only if you win on appeal. If you hire a lawyer before you file and your case is approved on the first try, you still pay the fee.

If you were denied and want to appeal, a lawyer can be useful because the appeal process is more formal and involves submitting written arguments and sometimes attending a hearing before a judge. A lawyer can gather additional medical evidence, write the appeal brief, and represent you at the hearing. You do not have to hire a lawyer to appeal, but many people find it helpful.

To find a lawyer, ask your local bar association for a referral, search the National Organization of Social Security Claimants' Representatives (NOSSCR) directory, or ask your doctor if they know a disability lawyer. Interview at least two lawyers before you decide. Ask about their experience with SSDI cases, their fee structure, and how they communicate with clients.

Frequently Asked Questions

How long does it take to hear back after I file?

If you file online or by phone, you receive a confirmation letter within 7 to 10 days. A decision on your case usually takes 3 to 6 months if you are approved, or longer if you must appeal. The SSA's current average is around 3 to 4 months for initial decisions, but this varies by region and by how quickly your doctors send in their records.

Can I work while my SSDI process is pending?

Yes. Working does not hurt your process. However, if you earn more than $1,550 per month (as of 2024, this amount changes yearly), the SSA may question whether you are truly unable to work. Keep records of your earnings and any work-related limitations you experience — these can help explain why you filed despite working.

What if I do not have a doctor?

You can still file, but the SSA will have difficulty approving your case without medical evidence. If you cannot afford a doctor, contact your local health department or a community health center to find low-cost or free medical care. Get at least one evaluation on record before you file, if possible. If you file without medical records, the SSA may deny your case and ask you to reapply once you have seen a doctor.

Do I need to report my process to my employer?

No. Your SSDI process is confidential. You do not have to tell your employer you filed. However, if your employer asks why you are taking time off for medical appointments, you can tell them you are seeking medical treatment without disclosing that you filed for disability.

What if I move or change my phone number while my case is pending?

Contact the SSA when ready with your new address or phone number. Call 1-800-772-1213 or visit your local Social Security office. If the SSA cannot reach you, they may close your case or make a decision without hearing from you. Keep your contact information current throughout the process.
