What You Need Before You Start
The Social Security Administration (SSA) does not require you to fill out forms in a specific order, but you will need certain documents ready before you walk into an office or call. Having these on hand cuts the time an interviewer spends hunting for information and reduces the chance your case gets delayed because something is missing.
Gather your birth certificate, proof of citizenship or legal residency (passport, green card, or naturalization papers), a driver's license or state ID, and your Social Security card. You will also need medical records that show your condition and how it limits your work — not just a diagnosis, but documentation of treatment, test results, and what your doctor says you cannot do. Bring tax returns or W-2s from the past two years, and if you have not worked recently, bring proof of when you last worked and how much you earned.
If you are explore based on a condition that developed while you were working, bring the date you stopped work or reduced your hours. If you have already been denied once, bring the denial letter — it tells SSA what they looked for before and what they want to see this time.
Key Takeaways
- Gather medical records, work history, and proof of identity before you contact SSA, because the agency will ask for these documents no matter which path you choose.
- You can start your process online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office — online is fastest if your medical records are already organized.
- SSA will assign you a case worker who contacts your doctors directly, so list every doctor who has treated your condition in the past five years.
- The process itself takes 15 to 30 minutes, but the full review of your medical evidence takes three to six months on average.
- If SSA denies your claim, you have 60 days from the denial letter to file an appeal, and most people who appeal with a lawyer win on the second or third try.
Starting Your process Online, by Phone, or In Person
The fastest way to begin is online at ssa.gov/applyfordisability. You create an account, answer questions about your work history and medical condition, and upload documents. SSA saves your progress, so you can stop and return later. The form takes 15 to 30 minutes if you have your information ready. When you finish, SSA sends you a confirmation number and tells you what happens next.
If you do not have a computer or prefer to talk to someone, call 1-800-772-1213 Monday through Friday, 7 a.m. to 7 p.m. your local time. Wait times are shortest early in the morning. An SSA representative will ask the same questions as the online form and can answer questions as you go. You will still need to mail or upload medical records afterward.
You can also walk into your local Social Security office without an appointment, though you may wait. Find your office at ssa.gov/locator. An interviewer will fill out the form with you and can tell you on the spot if anything is obviously missing. Bring all your documents — originals or certified copies, not photos.
What SSA Asks and Why It Matters
SSA will ask when your condition started, what doctors you have seen, what medications you take, and what work you have done in the past 15 years. They will ask about your education, whether you can read and write English, and whether you have ever been convicted of a felony. They will ask about your living situation, who supports you financially, and whether you receive any other benefits.
The reason SSA asks about work history is to calculate your Primary Insurance Amount (PIA) — the base payment you would receive if approved. The reason they ask about your condition in detail is to match it against the Blue Book, SSA's list of conditions that automatically may have access to for SSDI if your medical evidence is strong enough. If your condition is not on the list, SSA will assess whether your condition is as severe as one that is.
Be honest about everything, including gaps in work and any criminal history. SSA has access to your tax records and can verify what you say. Lying on an SSDI process is fraud and can result in criminal charges.
Submitting Medical Records and What SSA Does With Them
After you submit your process, SSA will send you a list of what medical records they need. You can ask your doctors' offices to send records directly to SSA, or you can collect them yourself and mail them to the address SSA provides. Medical records include office visit notes, test results (X-rays, blood work, MRI scans), hospital discharge summaries, and mental health treatment records.
SSA will also send your doctors a form called a Function Report or Residual Functional Capacity (RFC) form. Your doctor fills this out to describe what you can and cannot do — how long you can sit, stand, or walk; whether you can lift objects; whether you can concentrate on tasks; and how your condition affects your daily life. This form is one of the most important pieces of your case, so follow up with your doctor's office to make sure it gets completed and returned.
If you do not have a regular doctor, SSA may send you to a Consultative Examination (CE) — a one-time appointment with a doctor SSA pays for. This doctor will examine you and write a report. You do not choose the doctor, but you can ask SSA to schedule the exam at a time that works for you.
Understanding the Timeline and What Happens While You Wait
After you submit your process, SSA sends it to your state's Disability information Services (DDS) office. DDS reviews your medical records, your work history, and your age. If you are over 55 and have worked for many years, DDS may approve your case based on age and work history alone. If you are younger or have gaps in work, DDS will focus on whether your medical condition is severe enough to prevent any work.
The review takes an average of three to six months, though it can take longer if your medical records are incomplete or if DDS needs more information from your doctors. You can call SSA to check on your case, but calling does not speed it up. SSA will contact you if they need more information.
While you wait, you can work and earn money, but there are limits. If you earn more than $1,550 per month (as of 2024, this amount changes yearly), SSA may decide you are able to work and deny your case. If you earn less than this amount, you can continue working without affecting your case.
What to Do If SSA Denies Your Claim
About 65 to 70 percent of first-time applications are denied. A denial does not mean you are ineligible — it means SSA did not find enough medical evidence that your condition prevents work. The denial letter will explain the reason and tell you that you have 60 days to appeal.
You have four levels of appeal: Reconsideration (a different DDS examiner reviews your case), Hearing (you meet with an Administrative Law Judge), Appeals Council Review, and Federal Court. Most people who appeal with a lawyer win at the Hearing level. Lawyers who handle SSDI cases work on contingency, meaning they take payment only if you win, and SSA limits what they can charge to 25 percent of your back pay.
Between your denial and your Hearing, gather new medical records if your condition has worsened. Ask your doctors to write a statement saying you cannot work. If you have started new treatment or been hospitalized, include those records. The more recent and detailed your medical evidence, the stronger your appeal.
Getting Help From a Representative or Lawyer
You do not need a lawyer to explore for SSDI, but having one increases your chances of winning on appeal. A SSDI representative can be a lawyer, a non-lawyer advocate, or a social worker certified by SSA. You can find representatives through the National Organization of Social Security Claimants' Representatives (NOSSCR) at nosscr.org, or ask your local legal aid office.
If you cannot afford a lawyer, contact your state or local legal aid society. Many offer free help with SSDI cases. You can also ask SSA for a list of representatives in your area. Before you hire anyone, ask what they charge, whether they work on contingency, and whether they have handled cases like yours.
A representative can help you gather medical records, prepare for a Hearing, and communicate with SSA. They cannot speed up SSA's review, but they can make sure your case is presented as strongly as possible.
Frequently Asked Questions
Can I explore for SSDI if I am still working?
Yes. You can work and earn up to about $1,550 per month without affecting your case. If you earn more than that, SSA may assume you are able to work and deny your process. If you are approved, you can continue working for nine months after approval without losing benefits — this is called the Trial Work Period.
What if I do not have medical records from a doctor?
SSA can send you to a Consultative Examination at no cost to you. The doctor will examine you and write a report. If you have been treated at a hospital or emergency room, ask for those records — they count as medical evidence even if you do not have a regular doctor.
How much back pay will I receive if I am approved?
SSA pays back to the month you stopped work or the month you turned 62, whichever is later. If you were approved in month 12 but stopped work in month 1, you receive 11 months of back pay. The exact amount depends on your work history and earnings record.
Can I reapply if I was denied before?
Yes. You can file a new process after your previous case is closed, usually 12 months after a denial. A new process is useful if your condition has worsened, you have new medical evidence, or significant time has passed. You can also appeal your denial instead of reapplying — appeal is usually faster.
What happens to my process if I move?
Tell SSA your new address when ready. Your case will be transferred to the DDS office in your new state. Moves can cause delays, so notify SSA as soon as you know you are moving. You can update your address online at ssa.gov, by phone, or in person at your new local office.
