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 treating physicians, including their contact information and addresses. Have your most recent medical records, a list of current medications, and any prior denial letters ready for the claims representative.

Avoid submitting an incomplete work history, which often leads to unnecessary processing delays. Many people fail to provide recent medical records from all treating providers, which weakens the initial application. Do not overlook mental health conditions when describing your limitations, as these are as important as physical impairments. Always read every form thoroughly before signing to ensure your information is accurate.

Should you bring an attorney?

Applying for benefits is a complex legal process where the evidence you submit today forms the foundation of your future appeal. Most people who apply without professional guidance face significant hurdles if their initial application is denied. An attorney can help you organize your medical evidence and ensure your application accurately reflects your disability. Request a free case review to understand how to strengthen your claim before you visit the office.
