Before you visit
Bring a valid government-issued photo ID and a detailed 15-year work history to your appointment. You should also provide a list of all treating physicians with their contact information, recent medical records, a current list of medications, and any previous denial letters. A typical appointment lasts between 45 and 90 minutes as a representative reviews your file. Being organized helps the claims representative process your application more efficiently.
Avoid submitting an incomplete work history, which is a frequent cause of processing delays. You should also provide the most recent medical records and mention all conditions that impact your ability to work. Never sign forms without reading them thoroughly, as inaccuracies can lead to unnecessary denials. Working with an attorney early on can help you avoid these common pitfalls.
Should you bring an attorney?
Applying for SSDI is a complex process where the evidence you provide at the start defines your entire appeal record. If you apply without legal guidance, you may face challenges if your initial application is denied. A free case review can help you understand your options and ensure your application is as strong as possible from day one.
