What You Need to Know Before You Start

Social Security Disability Insurance (SSDI) is a federal program that pays monthly benefits to people who cannot work because of a medical condition expected to last at least 12 months or result in death. You file through the Social Security Administration (SSA), and the process typically takes three to six months from start to decision — though some cases take longer.

You do not need a lawyer to file, but you will need medical records that document your condition, proof of your work history, and personal identification. The SSA will review your medical evidence against their own standards for disability, not your doctor's opinion alone. Understanding what they look for and what documents matter most will help you prepare a complete file the first time.

Key Takeaways

  • You can file for SSDI online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office; online filing is fastest and you can save your progress.
  • You must have worked long enough and recently enough under Social Security to have earned enough work credits — the SSA will tell you during the filing process whether you meet this requirement.
  • Medical records from the past 12 months are most important; bring records from every doctor, hospital, or specialist who has treated your condition.
  • The SSA will request medical records directly from your providers if you give permission, so you do not have to collect and mail them yourself.
  • If the SSA denies your claim, you have 60 days to file an appeal; most people who appeal with new medical evidence or a lawyer's help succeed on reconsideration or at a hearing.

Gather Your Documents Before You File

The SSA will ask for specific information during your filing session, and having it ready speeds up the process. You will need your Social Security number, birth certificate, proof of citizenship or legal residency (passport, green card, or state ID), and your most recent tax return or W-2 form to verify your work history.

For your medical condition, collect the names and phone numbers of every doctor, hospital, clinic, and mental health provider who has treated you in the past 12 months. Write down the dates you saw them and what they treated you for. If you have recent test results, imaging reports, or hospital discharge papers, gather those too — the SSA will request full records from your providers, but having this list ready makes the process clearer.

You will also need information about any jobs you held in the past 15 years, including the dates you worked, what you did, and how much you earned. If you are currently working, the SSA needs to know your current monthly earnings.

File Your Claim Online, by Phone, or In Person

The fastest way to file is online at ssa.gov/applyfordisability. The form takes 15 to 20 minutes if you have your documents ready, and you can save your progress and return later. You will create a my Social Security account if you do not already have one, then answer questions about your medical condition, work history, and personal background. At the end, you will see a summary to review before you submit.

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. Wait times are longest early in the week and in the morning. An SSA representative will ask the same questions as the online form and will tell you on the call whether you have enough work credits to continue.

You can also file in person at your local Social Security office. Find the nearest one at ssa.gov/locator. Walk-in appointments are available, but calling ahead to schedule an appointment usually means a shorter wait. Bring all your documents with you.

What Happens After You File

After you submit your claim, the SSA sends you a receipt notice with a claim number. Write this number down — you will use it to check the status of your case. You can check your claim status online at my Social Security, by phone at 1-800-772-1213, or by visiting your local office.

The SSA will request medical records directly from your doctors and hospitals using the authorization you signed during filing. This usually takes two to four weeks. If a provider is slow to respond, the SSA may send a follow-up request or ask you to have the records sent. You can also contact your providers directly and ask them to send records to the SSA faster.

While the SSA reviews your case, a disability examiner will look at your medical records and compare them to the SSA's rules for disability. The SSA has a list of conditions that automatically meet their disability standard if your medical records match certain criteria — these are called the "Blue Book" listings. If your condition is not on the list, the examiner will assess whether your condition prevents you from doing any kind of work.

You will receive a decision letter in the mail, usually within three to six months. The letter will say whether you were approved, denied, or approved for a different program (like Supplemental Security Income, or SSI). If you were approved, it will tell you when your benefits start and how much you will receive each month.

Understanding Work Credits and Recent Work

To receive SSDI, you must have worked long enough under Social Security to have earned enough work credits. You earn one work credit for every $1,470 you earn in a year (this amount changes yearly). Most people need 40 work credits total, with at least 20 earned in the 10 years before they became disabled.

The SSA calculates this automatically when you file — you do not need to do anything. If you do not have enough work credits, the SSA will tell you in the decision letter and may suggest you file for Supplemental Security Income (SSI) instead, which has different rules and does not require work credits.

If you have worked recently but not continuously, the SSA still counts the credits you earned. Self-employment income counts the same way as wages, as long as you reported it on your tax return.

What to Do If Your Claim Is Denied

If the SSA denies your claim, you have 60 days from the date on the denial letter to file an appeal. Do not wait — if you miss this important date, you will have to file a new claim and start over.

The first level of appeal is called reconsideration. You request reconsideration by completing Form SSA-561-U2, which you can read from ssa.gov or get from your local Social Security office. Mail it to the address on your denial letter, or file it online at my Social Security. A different examiner will review your case, and you can submit new medical records or other evidence.

If reconsideration is also denied, you can request a hearing before an Administrative Law Judge (ALJ). This is where many people succeed, especially if they have new medical evidence or representation. You have 60 days from the reconsideration denial to request a hearing. At a hearing, you can present evidence, answer questions, and have a representative speak on your behalf.

Many people hire a disability representative or lawyer for the hearing stage. Representatives are paid only if you win, and their fee is limited by law to 25 percent of your back pay (the money owed from when you became disabled to when you were approved), up to $7,200.

Frequently Asked Questions

Can I work while I wait for a decision?

Yes. Working does not disqualify you from SSDI, but the SSA will consider your current work when deciding whether you are disabled. If you are earning more than $1,550 per month (this amount changes yearly), the SSA may conclude you can work and deny your claim. Report any work you do to the SSA during your filing.

How much will I receive each month?

Your monthly benefit is based on your lifetime earnings record, not on how disabled you are. The average SSDI payment is around $1,500 per month, but it varies widely. The SSA will estimate your payment amount in your approval letter. You can also see an estimate at my Social Security before you file.

Do I need a lawyer to file?

No. You can file on your own, and many people do. A lawyer or representative is most useful if your claim is denied and you are appealing, especially at the hearing stage. If you cannot afford a lawyer, some organizations offer free representation to people with disabilities.

What if I have not worked in several years?

You may not have enough recent work credits to may have access to for SSDI. The SSA will tell you during filing whether you meet the work requirement. If you do not, you may be able to file for Supplemental Security Income (SSI) instead, which does not require work history but has strict income and resource limits.

Can I file for someone else, like a family member?

No. Only the person with the disability can file for SSDI benefits. If someone is unable to manage their own affairs, a court-appointed representative or family member with power of attorney can file on their behalf, but the SSA will need legal documentation.
