Before you visit
To prepare for your appointment at San Leandro, bring a government-issued photo ID and a detailed work history covering the last 15 years. You should also provide a comprehensive list of all treating physicians with their contact information, along with your most recent medical records and a current list of medications. If you have received any prior denial notices, bring those documents as well. Expect your interview with a claims representative to last between 45 and 90 minutes as they verify your information and process your application.
Common mistakes that delay claims include providing an incomplete work history or failing to include recent medical records from all treating providers. Many applicants also neglect to mention mental health conditions that contribute to their inability to work. Avoid signing any forms at the office without reading them thoroughly to ensure all information is accurate. An attorney can help you avoid these errors by ensuring your application is complete and well-documented from the start.
Should you bring an attorney?
Applying for SSDI is a complex legal process where the evidence you submit today forms the foundation of your case. Most people who apply without professional guidance face significant hurdles if their initial application is denied. An attorney can help you understand your options and ensure your medical evidence is properly presented to the Social Security Administration.
