Step 1: Confirm Your SSDI Eligibility

Before filing, ensure you meet the basic SSDI requirements:

• You have a qualifying medical condition that prevents you from working for at least 12 months (or is expected to result in death).
• You have earned enough work credits by paying into Social Security through past employment.

Not sure if you qualify? Use the SSA’s Benefits Eligibility Screening Tool on ssa.gov to check.

Step 2: Gather Your Information and Documents

To avoid delays, prepare the following:

• Social Security number and proof of age
• Names and contact info for all medical providers
• Detailed work history from the past 15 years
• Medical records, prescriptions, lab results, and test reports
• Recent W-2 forms or tax returns

Step 3: File Your Application

There are three ways to apply for SSDI in Illinois:

• Online at ssa.gov
• By phone at 1-800-772-1213
• In person at your local SSA office (appointments recommended)

When filling out your application:

• Be honest and detailed about your condition
• List every doctor, clinic, or hospital you’ve visited
• Include mental and physical limitations that affect your ability to work

Step 4: Track Your Claim Status

After submitting, you can:

• Create an SSA online account to monitor your application
• Call your local SSA office to ask for updates
• Respond promptly if the SSA contacts you for additional information

The decision process may take 3 to 6 months, sometimes longer. If your claim is denied, you’ll have the option to appeal.

Step 5: Be Prepared for a Possible Appeal

Many SSDI applications are denied at first. If that happens:

• Request reconsideration within 60 days
• If denied again, you can request a hearing before an Administrative Law Judge
• Submit any new medical evidence during the appeal process
