Social Security Disability Insurance (SSDI) is a federal program that provides monthly benefits to people who cannot work due to a long-term disability.
To qualify, you must have worked in jobs covered by Social Security and earned enough work credits.
The Social Security Administration (SSA) reviews both your medical condition and your work history before approving benefits.
How Do You Start an SSDI Application?
You can apply for SSDI in three main ways:
- Online through the SSA website.
- By phone by calling the Social Security Administration at 1-800-772-1213.
- In person by visiting your local Social Security office (appointment recommended).
Applying online is the fastest option because it allows you to complete the forms at your own pace and upload supporting documents.
What Documents Do You Need to Apply for SSDI?
When applying, you must provide:
- Your Social Security number and birth certificate.
- Medical records, doctor’s reports, and test results.
- A list of medications you are taking.
- Work history and recent W-2 forms or tax returns.
- Information about your spouse and children (if applying for family benefits).
The more complete your documentation, the faster the SSA can process your claim.
What Medical Conditions Qualify for SSDI?
The SSA has a Blue Book listing medical conditions that may qualify for SSDI. Some common conditions include:
- Severe heart disease.
- Musculoskeletal disorders such as back injuries.
- Neurological conditions like epilepsy or multiple sclerosis.
- Mental health disorders such as depression or schizophrenia.
Even if your condition is not listed, you may still qualify if it prevents you from working for at least 12 months.
How Long Does It Take to Get Approved for SSDI?
The average SSDI application takes 3 to 6 months for an initial decision. However, many applications are denied the first time.
If denied, you can file an appeal, which may take several more months.
Having detailed medical evidence increases your chance of approval.
Can You Work While Applying for SSDI?
You can work while applying, but your earnings must be below the Substantial Gainful Activity (SGA) limit, which in 2025 is $1,590 per month for non-blind applicants and $2,680 for blind applicants.
Earning above this limit usually results in a denial.
Do You Need a Lawyer to Apply for SSDI?
You do not need a lawyer to file an SSDI claim, but many applicants hire one if they are denied and need to appeal.
Disability attorneys typically work on a contingency basis, meaning they only get paid if you win your case.
