What medical proof is required for SSDI in Illinois?

By Hogan Smith

Updated 08/05/2025


To get approved for Social Security Disability Insurance (SSDI) in Illinois, you must prove that your medical condition prevents you from working. Medical documentation is the foundation of a successful SSDI claim — and incomplete or weak evidence is one of the most common reasons for denial.

Please answer a few questions to help us determine your eligibility.


Types of Medical Evidence You Need

The Social Security Administration (SSA) wants to see objective, consistent documentation that supports your disability. The most important records include:


  • Doctor’s treatment notes and exam findings
  • Hospital and clinic records
  • Diagnostic test results, such as MRIs, X-rays, or blood work
  • Mental health records, if applicable
  • Specialist reports supporting your diagnosis and limitations
  • Surgical and therapy notes, if treatment was required


SSA looks for ongoing treatment, not just a one-time visit. The more detailed and recent your records are, the stronger your case will be.


Statements From Your Doctor

A Medical Source Statement from your treating physician can be especially powerful. This written opinion should explain:


  • Your diagnosed condition(s)
  • Your physical or mental limitations
  • How your condition affects your ability to work
  • Whether your disability meets SSA’s definition of “total disability”


SSA gives more weight to opinions from long-term treating doctors rather than one-time evaluations.


Consistency Is Key

SSA will compare your medical records to:


  • Your work history
  • Your daily activities
  • Your statements in your SSDI application


Any inconsistencies — such as saying you can’t walk, but medical records say you’re mobile — can hurt your case. Make sure your documentation tells a clear, honest, and consistent story.


SSA’s Blue Book Conditions

SSA uses a medical guide called the “Blue Book” to evaluate disabilities. If your condition matches or equals a listing in the Blue Book, and your documentation proves it, your claim may be approved more quickly.


What If You Don’t Have Enough Medical Evidence?

If your records are limited, SSA might send you for a consultative exam (CE) with one of their doctors. However, your own medical providers usually offer stronger support — so it’s best to submit complete records yourself when possible.
