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 comprehensive list of all your treating physicians, including their contact information and addresses. Have your most recent medical records, a list of your current medications, and any previous denial letters ready for the claims representative. Appointments typically last between 45 and 90 minutes, so plan your travel accordingly.

Avoid submitting an incomplete work history, as this often leads to unnecessary processing delays. Many applicants also fail to include recent medical records or forget to disclose conditions that impact your ability to work. Never sign any forms at the office without reading them thoroughly to ensure all information is accurate. An attorney can help you avoid these common pitfalls.
