The Basic Path to explore 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 (TTY 1-800-325-0778), or in person at your local Social Security office. The online process takes about 15 minutes if you have your Social Security number, birth certificate, and medical records ready. You do not need a lawyer to file, though you can hire one later if your case is denied.

The process itself is straightforward — you answer questions about your work history, your medical condition, and the date your disability began. Social Security calls this your "onset date," and it matters because benefits can only go back to the month you became unable to work, not earlier. You will need to list every job you have held in the past 15 years and the names of doctors or hospitals that have treated your condition.

After you file, Social Security sends your case to your state's Disability information Services (DDS) office. This is a separate agency that decides whether you meet the medical rules for disability. The DDS office will contact your doctors directly to request medical records, so you do not have to gather them yourself, though providing them upfront speeds things up. Most decisions take three to six months, though some take longer if your medical evidence is incomplete.

Key Takeaways

  • You can file online at ssa.gov, by phone, or at your local Social Security office, and the online process takes about 15 minutes.
  • Your onset date — the month you became unable to work — determines when benefits can begin, so accuracy matters for your back pay.
  • Social Security requests medical records from your doctors directly, but providing them yourself when you file speeds up the decision.
  • A separate state agency called Disability information Services makes the medical decision, and most cases take three to six months.
  • You can work with a lawyer or non-lawyer representative, but you do not need one to file your initial claim.

What Documents You Need Before You File

Gather these documents before you start the process: your Social Security number, birth certificate, proof of U.S. citizenship or legal residency (passport, green card, or naturalization papers), and a driver's license or state ID. You will also need your W-2 forms or tax returns from the past two years to show your work history and earnings.

For your medical condition, write down the names and phone numbers of every doctor, therapist, hospital, or clinic that has treated you in the past year. You do not need the actual medical records yet — Social Security will request them — but having contact information ready means the DDS office can reach them faster. If you have had recent test results, imaging, or hospital discharge papers, you can upload those during the process, which often speeds the decision.

If you have already been denied for disability benefits before, gather the denial letter. Social Security will ask whether you have filed before, and if you have, they will review your old case to see what has changed medically since then.

Filing Online, by Phone, or In Person

The online process at ssa.gov/applyfordisability is the fastest route. You create a my Social Security account (or log in if you have one), answer the medical and work history questions, and submit. The system saves your progress if you need to stop and come back. You get a confirmation number when ready, and Social Security mails you a receipt within two weeks.

If you prefer to file by phone, call 1-800-772-1213 Monday through Friday, 7 a.m. to 7 p.m. your local time. A representative will walk you through the questions and file your process over the phone. This takes about 30 minutes. You can also visit your local Social Security office in person — find the nearest one at ssa.gov/locator — and a representative will file for you there. In-person filing is useful if you have complex work history or medical issues and want to explain them directly.

No matter which method you choose, you will receive the same decision timeline and the same medical review. Online is fastest because there is no wait for a phone line or office appointment, but all three methods are equally valid.

What Happens After You File

Within two weeks, Social Security mails you a receipt notice with your case number. Keep this number — you will use it to check the status of your case online at ssa.gov or by calling 1-800-772-1213. The receipt also lists the medical evidence Social Security will request from your doctors.

Your case then goes to your state's Disability information Services office. A disability examiner there reviews your medical records and decides whether your condition meets Social Security's definition of disability. This means your condition must prevent you from doing any substantial work for at least 12 months or result in death. The examiner does not decide based on your age, education, or how hard you have worked — only on your medical condition and your ability to work.

The DDS office contacts your doctors directly for records. This usually takes four to eight weeks. If your doctors are slow to respond, the DDS office will send a follow-up request. You can speed this up by calling your doctor's office and asking them to send the records to the DDS office right away — give them your case number from your receipt notice.

Understanding the Medical Review Process

Social Security uses a five-step process to decide whether you are disabled. First, they check whether you are working and earning more than $1,550 per month (in 2024; this amount changes yearly). If you are, they usually deny your case because you are doing substantial work. If you are not working or earning less than that, they move to step two.

Step two asks whether your medical condition is severe — meaning it significantly limits your ability to do basic work activities like sitting, standing, concentrating, or remembering instructions. If Social Security finds your condition is not severe, they deny your case. If it is severe, they move to step three.

Step three compares your condition to Social Security's list of impairments called the Blue Book. This list describes medical conditions that automatically may have access to for disability if your medical evidence matches the criteria. If your condition matches a Blue Book listing, you are approved. If it does not, the examiner moves to step four.

Step four asks whether you can do your past work. The examiner looks at the physical and mental demands of jobs you have held in the past 15 years and whether your condition prevents you from doing them. If you can still do past work, they deny your case. If you cannot, they move to step five.

Step five asks whether you can do any other work that exists in the national economy, considering your age, education, work experience, and medical condition. This is the hardest step to win because Social Security only has to show that some work exists that you could do, not that jobs are actually available near you. If the examiner finds you cannot do any work, you are approved.

What to Do If Your Case Is Denied

If Social Security denies your case, you receive a written decision explaining why. You have 60 days from the date on the denial letter to file a request for reconsideration. This means a different examiner at the DDS office reviews your case and any new medical evidence you have gathered since you first filed.

To request reconsideration, call 1-800-772-1213 or visit your local Social Security office. You can also file online at ssa.gov if you have a my Social Security account. Tell Social Security that you want to request reconsideration and provide any new medical records, test results, or doctor's statements that show your condition has worsened or that you have new medical problems.

If reconsideration is also denied, you can request a hearing before an Administrative Law Judge (ALJ). This is a formal hearing where you can present evidence and testify about your condition. Many people hire a lawyer or non-lawyer representative at this stage because the hearing process is more complex. The ALJ makes a new decision based on all the evidence presented at the hearing.

Working With a Representative

You can hire a lawyer or a non-lawyer representative called a "may have access to representative" to help with your case. They can file your process, gather medical evidence, prepare for a hearing, and represent you at the hearing. You do not pay them unless you win your case — Social Security takes their fee (up to $6,000 or 25 percent of your back pay, whichever is less) directly from your back pay award.

To hire a representative, you sign a form called an "Authorization to Represent" (Form SSA-1696). Your representative must be approved by Social Security, which means they have passed a test or are a lawyer. You can find approved representatives through the National Organization of Social Security Claimants' Representatives (nosscr.org) or by asking your local legal aid office.

Many people file their initial claim without a representative and only hire one if they are denied and need to request reconsideration or a hearing. This is a reasonable approach because the initial process is straightforward. However, if your medical history is complex or you have been denied before, a representative can help from the start.

Frequently Asked Questions

Can I file for SSDI if I am still working?

You can file, but Social Security will likely deny your case if you are earning more than $1,550 per month (in 2024). If you are working part-time and earning less than that, you can file and may be approved if your medical condition meets the disability standard. The earnings limit changes yearly, so check ssa.gov for the current amount.

How far back can SSDI benefits go?

Benefits can go back to the month you became unable to work, but no earlier than 12 months before you file your process. This is called your "onset date." If you file in January 2024 but became disabled in January 2022, you can only receive back pay from January 2023 onward. This is why filing as soon as you become disabled is important.

What if I do not have medical records from my doctors?

Social Security will request them directly from your doctors and hospitals. However, if your doctors have closed their practice or records are old, you may need to see a new doctor to get current medical evidence. If you cannot afford a doctor, ask Social Security about a Consultative Examination (CE) — they will pay for you to see a doctor they choose to evaluate your condition.

How do I check the status of my process?

Log into your my Social Security account at ssa.gov, or call 1-800-772-1213 and give the representative your case number from your receipt notice. You can also visit your local Social Security office. Status updates usually appear online within a few days of any change in your case.

Can I file for SSDI and SSI at the same time?

Yes. SSDI is based on your work history; SSI is based on income and assets. You can file for both in the same process. If you have worked enough to may have access to for SSDI, you will receive SSDI. If you have not worked enough but have low income and assets, you may receive SSI instead or in addition to SSDI.
