Hello Matthew,
Thank you for your question. When you apply for Social Security Disability Insurance (SSDI), you must establish the date that you were unable to work due to a medical condition or disability. This is known as your disability onset date. The date you pick is an important one and can have a significant impact on the amount of back benefits you will receive if any. It’s best you speak to an expert; therefore, I would like to refer you to the Patient Advocate Foundation (PAF) to speak to a Case Manager to help answer your question. They can be reached at 800-532-5274.
