Before you visit

To prepare for your appointment, bring a valid government-issued photo ID and a detailed work history including dates and job duties. You should also provide a comprehensive list of all treating physicians, including their contact information and addresses, along with any recent medical records or test results. If you have received prior denial letters, bring those documents as well. Arrive prepared to discuss the specifics of your condition and work limitations.

You may delay your benefits by submitting incomplete work histories or failing to provide the most recent medical records from your specialists. Another common error is neglecting to mention mental health conditions, which are just as relevant to your claim as physical impairments. Avoid signing any forms without reading them thoroughly, as inaccuracies can lead to processing delays. An attorney can help you avoid these pitfalls and ensure your file is complete.

Should you bring an attorney?

The initial application stage is a critical time to establish the evidence that will support your claim throughout the process. Many applicants who apply without guidance find themselves facing a denial that could have been avoided with better preparation. An attorney can help you review your case, gather the necessary medical evidence, and ensure your application is presented clearly. Request a free case review to understand your options before your appointment.
