The Basic Steps to File for SSDI

To file for Social Security Disability Insurance, you submit a claim to the Social Security Administration (SSA) through 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 SSA will ask you to provide medical records, work history, and details about your condition. You do not need a lawyer to file, though some people hire one to represent them later in the process if their claim is denied.

The entire process from filing to a final decision typically takes three to six months for an initial claim, though some cases take longer. During this time, the SSA reviews your medical evidence and determines whether your condition meets their definition of disability — meaning you cannot work for at least 12 months or have a condition expected to result in death.

You can file at any time, but the SSA will only pay benefits back to the month you filed or the month you became unable to work, whichever is later. There is a five-month waiting period after your disability begins before payments start, so filing sooner rather than later protects your back pay.

Key Takeaways

  • You can file online, by phone, or in person; online filing at ssa.gov is usually fastest and requires the least paperwork upfront.
  • The SSA needs your medical records, work history, and a description of how your condition prevents you from working — you gather these, not the SSA.
  • The five-month waiting period means benefits do not start until the sixth month after your disability began, so filing early protects your right to back pay.
  • An initial decision usually comes within three to six months, but denial is common; you can request reconsideration or a hearing if your claim is denied.
  • You do not need a lawyer to file, but many people hire one only if they must appeal, paying them from your back pay if you win.

What Medical Records You Need to Gather

Before you file, collect records from every doctor, hospital, mental health provider, or specialist who has treated you for your condition. The SSA needs to see test results, imaging reports, treatment notes, and medication lists — not just a diagnosis. If you have been hospitalized, get discharge summaries. If you see a therapist or psychiatrist, get their clinical notes. If you have had surgery, get the operative report and follow-up notes.

You do not need to submit everything at once. You can file first and send records later, but the sooner you provide them, the sooner the SSA can make a decision. If your doctor's office charges for copies, budget for that cost — it is usually $10 to $50 per request. Many offices now offer online portals where you can read your own records for free.

If you have not seen a doctor recently, the SSA may ask you to get a consultative examination at their expense. This is a one-time appointment with a doctor they choose, and it does not cost you anything. The SSA uses this to fill gaps in your medical record when your own doctors have not documented enough detail.

How to File Online, by Phone, or In Person

Online filing is the fastest route. Go to ssa.gov, select "explore for Disability," and complete the online form. You will need your Social Security number, birth certificate, proof of citizenship or legal residency, and a list of your doctors and hospitals. You can save your progress and come back later. Once you submit, the SSA sends you a confirmation number and tells you what to do next.

Phone filing means calling 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 a list of your medical providers ready. The representative will ask you questions and fill out the form on their end. You will receive a confirmation number and written summary in the mail.

In-person filing at your local Social Security office is useful if you need help understanding the form or have complex work history. Call ahead to make an appointment — walk-ins may have long waits. Bring your Social Security card, birth certificate, proof of citizenship or legal residency, and a list of all doctors and hospitals who have treated you.

What Information the SSA Asks For

The SSA will ask you to describe your condition, when it started, and how it affects your ability to work. Be specific: instead of "I have back pain," write "I cannot sit for more than 30 minutes without severe pain, and I cannot lift anything heavier than 10 pounds." The more detail you provide about your daily limitations, the stronger your claim.

You will also provide your complete work history for the past 15 years, including job titles, dates, and the names and addresses of employers. The SSA uses this to understand what kind of work you did and whether your condition prevents you from doing that work or any other work.

List every doctor, hospital, clinic, and mental health provider you have seen, including the dates of your visits and the reason for each visit. If you have been treated for multiple conditions, list all of them. The SSA will contact these providers directly to request your records.

Understanding the SSA's Medical Review Process

After you file, a disability examiner at your state's Disability information Services (DDS) office reviews your medical records. They do not make a judgment about whether you are "sick enough" — they check whether your condition meets the SSA's medical criteria. The SSA publishes a list called the Blue Book that describes conditions that automatically may have access to; if your condition is on that list and your medical evidence matches, approval is more likely.

If your condition is not on the Blue Book, the examiner compares your medical records to the criteria for your condition. They look for objective evidence: test results, imaging, lab work, and clinical observations from your doctors. They also consider how long your condition has lasted and whether treatment has helped.

If your medical records are incomplete, the SSA will ask your doctors for more information. This can add weeks to the process. If your doctors do not respond quickly, the SSA may schedule a consultative examination instead.

What Happens If Your Claim Is Denied

Denial is common on the first process — roughly two-thirds of initial claims are denied. If yours is denied, you receive a written notice explaining the reason. Common reasons include insufficient medical evidence, a condition that does not meet SSA criteria, or a finding that you can still work.

You have 60 days from the date on the denial letter to request reconsideration. This means a different examiner reviews your claim, usually with new or updated medical records you provide. Reconsideration is free and does not require a lawyer.

If reconsideration is also denied, you can request a hearing before an Administrative Law Judge (ALJ). This is where many people hire a lawyer, because the hearing is more formal and a lawyer can present your case. The ALJ listens to your testimony and your doctor's testimony, then makes a decision. Hearings typically happen four to six months after you request one, though this varies by region.

Working With a Lawyer or Representative

You do not need a lawyer to file for SSDI. Many people file on their own and win. However, if your claim is denied and you must appeal, a lawyer or non-lawyer representative can help you gather evidence, prepare for a hearing, and present your case to a judge.

If you hire a lawyer and win at any stage, they are paid from your back pay — the money the SSA owes you from the month your disability began. The lawyer's fee is capped at 25 percent of your back pay or $7,200, whichever is less. You do not pay anything upfront.

You can find a lawyer through the National Organization of Social Security Claimants' Representatives (NOSSCR) or by asking your local legal aid office. Many lawyers work on contingency, meaning they only get paid if you win.

What Happens After You Are Approved

Once the SSA approves your claim, you receive a notice telling you your benefit amount and your start date. Your first payment arrives by direct deposit or check, usually within two weeks. The SSA also enrolls you in Medicare automatically — you become may be able to access for Medicare Part A (hospital insurance) after you have been on SSDI for 24 months.

You must report changes to the SSA, including if you return to work, move, or change your contact information. If you work while on SSDI, the SSA has work incentive programs that let you earn money without losing your benefits when ready. These programs are complex, so speak with a work incentive planning specialist before you start working.

The SSA will review your case periodically to confirm you are still disabled. How often depends on whether your condition is expected to improve. If it is not expected to improve, reviews happen less frequently.

Frequently Asked Questions

Can I file for SSDI if I am still working?

Yes. You can file while working, but your earnings must be below the substantial gainful activity (SGA) limit — currently $1,550 per month in 2024, though this amount changes yearly. If you earn more than this, the SSA may find that you can still work and deny your claim. However, you can use work incentive programs to earn more without losing benefits once you are approved.

How far back does SSDI pay?

SSDI pays back to the month you became unable to work, minus the five-month waiting period. If you became disabled in January but did not file until September, you receive back pay from June (five months after January). If you file when ready, you protect the full amount of back pay owed to you.

What if I do not have recent medical records?

If you have not seen a doctor in a long time, the SSA may schedule a consultative examination at no cost to you. However, the longer the gap in your medical records, the harder it is to prove your condition is disabling. If possible, see a doctor before you file so your records are current.

Do I lose my benefits if I get married or have a child?

No. Your SSDI benefits are based on your own work record and disability, not your marital status or family size. However, your spouse and children may be able to receive benefits on your record. Contact the SSA to learn whether they may have access to.

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

If you have not worked enough to may have access to for SSDI, you may may have access to for Supplemental Security Income (SSI) instead. You can file for both at the same time. SSI is needs-based, so your income and assets matter. SSDI is not needs-based — only your work record and disability matter.
