The basic process: what you actually do

To file for Social Security Disability Insurance (SSDI), 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 for medical records, work history, and details about your condition. After you submit, the SSA sends your case to your state's Disability information Services (DDS) office, which reviews the medical evidence and decides whether your condition meets Social Security's definition of disability. The entire process typically takes three to six months, though some cases take longer.

You do not need a lawyer to file, though you can hire one if you choose. Many people file on their own the first time. If your claim is denied, you can appeal, and that is when many people bring in representation.

Key Takeaways

  • You file directly with the Social Security Administration online, by phone, or at a local office, and the SSA forwards your case to your state's Disability information Services.
  • Social Security requires medical evidence that your condition prevents you from working any job, not just your current job, and that it will last at least 12 months or result in death.
  • You must have worked long enough and recently enough to have earned sufficient work credits, which the SSA calculates based on your age and earnings history.
  • The decision process takes several months; during that time you can work and earn income, but high earnings may affect your case or future benefits.
  • If denied, you have the right to appeal, and most people who appeal with new medical evidence or representation succeed on the second or third try.

What the SSA needs from you before you file

Gather your Social Security number, birth certificate, and proof of citizenship or legal residency before you start. You will also need your medical records — the SSA will request these directly from your doctors, but having copies yourself speeds things up. Bring documentation of any surgeries, hospitalizations, medications, test results, and ongoing treatment. The more recent and detailed your medical records, the stronger your case.

You will also need your work history: dates you worked, names of employers, and your job titles. The SSA has access to your earnings record through your Social Security account, so you do not have to recreate it, but knowing your work history helps you answer questions accurately during the application.

Work credits and why they matter

Social Security does not pay disability to everyone with a medical condition. You must have worked and paid Social Security taxes long enough to have earned sufficient work credits. In 2024, you earn one credit for each $1,730 in wages (this amount changes yearly). You can earn up to four credits per year. Most people need 40 credits total, with at least 20 earned in the 10 years before they became disabled.

If you are under 31, the rules are different — you may need fewer credits. The SSA calculates your specific requirement based on your age when you became disabled. You can check your work credits and earnings record by creating an account at ssa.gov; the SSA will tell you exactly how many credits you have and whether you meet the requirement.

How the SSA defines disability

Social Security's definition of disability is strict: your condition must prevent you from doing any substantial work, not just your current job. "Substantial work" means earning more than a set monthly amount (in 2024, $1,550 per month; this changes yearly). Your condition must be expected to last at least 12 months or result in death. A temporary injury or illness, even a serious one, does not may have access to.

The SSA uses a five-step process to evaluate your case. First, they check whether you are working and earning substantial income — if you are, they usually deny the claim. Second, they determine whether your condition is severe enough to affect your ability to work. Third, they check whether your condition matches one of the SSA's listed impairments (called the "Blue Book"). Fourth, if it does not match exactly, they assess whether you can do your past work. Fifth, they assess whether you can do any other work that exists in the national economy.

Medical evidence: what carries weight

The SSA bases its decision almost entirely on medical evidence. Statements from your doctors carry the most weight — specifically, statements about what your condition prevents you from doing, how long symptoms last, what medications you take, and how treatment affects your ability to function. Treatment records from hospitals, clinics, and specialists are stronger than a single doctor's note.

Objective test results (imaging, lab work, nerve tests) are valuable, but the SSA also considers subjective symptoms you report — pain, fatigue, memory problems — if your medical records support them. If you have not been treated for your condition, or if you have not sought treatment in months, the SSA will likely deny your claim. Consistent, ongoing medical care is one of the strongest indicators that your condition is real and disabling.

What happens after you file

After you submit your claim, the SSA sends it to your state's Disability information Services office within a few days. DDS reviews your medical records, may request additional records from your doctors, and makes the initial decision. You will receive a letter in the mail — not an email — telling you whether you were approved or denied. This letter also explains your appeal rights if you were denied.

While your case is being reviewed, you can continue to work and earn income. However, if you earn more than the substantial work level ($1,550 per month in 2024), the SSA may deny your claim or close your case. Once you are approved and benefits begin, you can earn up to a higher limit ($2,590 per month in 2024) during a nine-month trial work period without losing benefits.

Appealing a denial

If your claim is denied, you have 60 days from the date on the denial letter to appeal. The first level of appeal is called reconsideration: a different examiner at DDS reviews your case, usually with new medical evidence you provide. Many people are approved on reconsideration if they submit recent medical records or statements from their doctors explaining why they cannot work.

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 representation. An ALJ will review your entire case, may ask you questions, and can hear from a medical expert or vocational expert. The hearing process takes several months, but approval rates are significantly higher at this stage than at the initial claim stage.

Frequently Asked Questions

Can I work while my SSDI claim is being reviewed?

Yes. You can work and earn income during the review process without affecting your claim. However, if you earn more than $1,550 per month (in 2024), the SSA may interpret that as evidence you can work and deny your claim. Keep your earnings below the substantial work level if possible, or document that your work is part-time or temporary while you wait for a decision.

What if I do not have recent medical records?

Contact your doctors and ask them to send records to the SSA. If you have not seen a doctor recently, schedule an appointment before you file. The SSA will likely deny a claim without current medical evidence. If you cannot afford treatment, ask your doctor about low-cost clinics or whether they offer sliding-scale fees.

Do I need a lawyer to file for SSDI?

No, you can file on your own. Many people do. However, if your claim is denied and you appeal to a hearing, a lawyer or representative familiar with disability law significantly increases your chances of approval. Representatives are paid only if you win, and the fee is capped by Social Security law.

How long does it take to get approved?

Initial decisions typically take three to six months. Reconsideration takes another two to three months. A hearing before an ALJ can take six months to over a year. Some cases move faster; others take longer depending on how busy your state's DDS office is and whether you need to submit additional medical evidence.

What if I become disabled while I am already receiving Social Security retirement benefits?

Contact the SSA to report your disability. You may be able to switch to SSDI, which has different rules and may result in a different benefit amount. The SSA will review your case and determine which program applies to you.
