Before you visit
Bring a government-issued photo ID and a comprehensive work history covering the last 15 years to your appointment. You should also provide a list of all treating physicians with their contact information, recent medical records, and a current list of medications. If you have received any prior denial notices, bring those documents to help the representative understand your claim history.
You may delay your benefits by failing to provide a complete 15-year work history or omitting recent medical records from your primary care providers. Another common error is neglecting to mention conditions that contribute to your inability to work. Always review your application forms thoroughly before signing, as errors can lead to processing delays or incorrect benefit calculations.
Should you bring an attorney?
Working with an attorney early in the process helps ensure your medical evidence is properly documented for the state reviewers. If you apply without legal guidance, you may face significant hurdles if your initial application is denied. A free case review can help you understand your options and the strength of your evidence before you finalize your submission.
