The application process starts with the Social Security Administration, not your doctor

You file for Social Security Disability Insurance (SSDI) directly with the Social Security Administration (SSA). You can start the process online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office. The SSA will ask for medical records, work history, and details about your condition — not your doctor. Your doctor's records come later, as supporting evidence.

The entire process typically takes three to six months for an initial decision, though some cases take longer. Many people are denied on the first application; if that happens, you can request reconsideration or file an appeal. Understanding each step and what documents you need before you start can speed things up.

Key Takeaways

  • You file directly with the Social Security Administration online, by phone, or at your local office — not through your employer or doctor.
  • You will need your Social Security number, birth certificate, medical records from the past three years, and a list of all jobs you have held in the past 15 years.
  • The SSA asks for permission to contact your doctors and hospitals; you do not need to collect and mail records yourself, though having them ready speeds the process.
  • If you are denied, you can request reconsideration within 60 days, which sends your case to a different SSA reviewer.
  • If reconsideration is also denied, you can request a hearing before an administrative law judge, which is where many people's cases are approved.

What documents and information you need before you start

Gather these items before you file. You will not need to submit everything at once, but having them ready means you can answer questions without delays. The SSA will also ask for permission to request records directly from your doctors and hospitals, so you do not have to collect paper copies yourself — though if you have recent records, providing them can speed up the review.

You need your Social Security number, birth certificate, and proof of citizenship or legal residency (passport, green card, or state ID). Bring a list of all jobs you have held in the past 15 years, including employer names, dates, and the type of work you did. The SSA uses this to calculate your work credits and understand your work history.

Medical records are the core of your case. Gather records from the past three years covering your condition, including doctor visits, hospital stays, test results, imaging (X-rays, MRIs), and any mental health treatment. If you take medications, have a list with dosages. If you see a therapist, psychiatrist, or specialist, their notes matter more than your primary care doctor's because they document your condition in detail.

How to file online, by phone, or in person

Online filing is the fastest route. Go to ssa.gov and look for "Apply for Disability." You can create an account and fill out the application over several sessions — you do not have to finish it all at once. The online form asks about your medical condition, work history, and living situation. When you submit, the SSA sends you a confirmation number.

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 the application. This takes about 30 minutes. You will receive a confirmation number and a notice in the mail within two weeks.

In person at your local Social Security office. Find your office at ssa.gov/locator. Walk-ins are accepted, but you may wait. Bring the documents listed above. A representative will help you fill out the application and answer questions about your condition and work history. You will leave with a confirmation number.

What happens after you file: the review timeline

After you file, the SSA sends your case to a Disability information Services (DDS) office in your state. This office is separate from Social Security and reviews medical evidence. They will contact your doctors and hospitals to request records — you authorized this when you filed. This step usually takes four to eight weeks.

A medical or vocational expert at DDS reviews your records against the SSA's list of conditions that automatically may have access to for benefits (called the "Blue Book"). If your condition is on the list and your medical records match the criteria, you may be approved without further review. If your condition is not on the list or the records do not fully match, DDS may request additional testing or a consultative exam — a one-time appointment with a doctor chosen by the SSA, paid for by them.

Once DDS completes its review, they send a decision to the SSA, which mails you a notice. This entire process takes three to six months on average, though some cases take longer if additional medical evidence is needed.

What to do if your application is denied

About 65 to 70 percent of first-time applicants are denied. Denial does not mean you cannot receive benefits — it means the SSA did not find enough medical evidence that your condition prevents you from working. You have the right to challenge the decision.

Within 60 days of the denial notice, you can request reconsideration. This sends your case to a different DDS reviewer who looks at your original records plus any new medical evidence you provide. If you have had additional doctor visits, test results, or hospitalizations since you first filed, include those. Reconsideration takes another two to three months.

If reconsideration is also denied, you can request a hearing before an administrative law judge (ALJ). This is where many people's cases are approved. You can represent yourself or hire a lawyer (many work on contingency, taking a percentage of back pay if you win). The hearing is informal — you sit across from the judge, who asks about your condition and work history. The judge may also ask a vocational expert whether jobs exist that you could do given your limitations. Request the hearing within 60 days of the reconsideration denial.

When benefits start and how much you receive

If you are approved, benefits begin the month after you meet the SSA's five-month waiting period. For example, if your condition began in January, your first check arrives in July (after five full months have passed). Back pay covers the months between when your condition began and when benefits start.

The amount you receive depends on your work history and earnings record, not on your condition. The SSA calculates a benefit based on your average lifetime earnings. In 2024, the average SSDI payment is around $1,550 per month, but individual amounts vary widely. You can see your estimated benefit on your Social Security account at ssa.gov.

Once you receive SSDI, you are also covered by Medicare after 24 months of benefits. You can work part-time and still receive benefits if your earnings stay below the "substantial gainful activity" limit, which changes yearly. Report any work to the SSA immediately.

How a lawyer can help and what it costs

You can file and appeal on your own, but many people hire a lawyer, especially for the hearing stage. A lawyer can organize your medical records, write the reconsideration request, prepare you for the hearing, and question the vocational expert. Lawyers who handle SSDI cases work on contingency, meaning they take a percentage of your back pay if you win — usually 25 percent, capped at $6,000 by federal law.

You do not pay anything upfront. If you are denied, you owe nothing. If you win, the SSA pays the lawyer directly from your back pay before sending you the remainder. You can find lawyers through the National Organization of Social Security Claimants' Representatives (nosscr.org) or by asking your local legal aid office.

Frequently Asked Questions

Can I file for SSDI if I am still working?

Yes. Your work history is what qualifies you for SSDI, not your current employment status. However, if you are earning above the "substantial gainful activity" limit (around $1,550 per month in 2024), the SSA may assume you are able to work and deny your claim. If you are working part-time or at reduced hours due to your condition, explain this in your application.

What if I do not have recent medical records?

Request them from your doctors and hospitals before you file. If you have not seen a doctor recently, the SSA may order a consultative exam at no cost to you. However, having your own records speeds the process. If you cannot afford medical care, explain this in your application — the SSA understands that some people delay treatment due to cost.

How long does reconsideration take?

Reconsideration typically takes two to three months. During this time, submit any new medical evidence — recent doctor visits, test results, or hospitalizations. New evidence can change the outcome. If you have not seen a doctor since your first application, consider scheduling an appointment and including those records with your reconsideration request.

What happens if I am approved but later return to work?

You can work and still receive SSDI if your earnings stay below the substantial gainful activity limit. If you earn more than that, your benefits stop, but you enter a nine-month trial work period where you keep full benefits while testing your ability to work. After the trial period, benefits continue for three more months before stopping. Report all work to the SSA immediately.

Can I file for my child's SSDI benefits?

No. Your child files their own claim based on their own work history (if they have one) or their own disability. However, if you receive SSDI, your child may be may be able to access for benefits as your dependent — this is a different program. Contact the SSA to learn whether your child qualifies based on your benefits.
