Before you visit
Bring a government-issued photo ID and a complete 15-year work history to your appointment. You should also provide a list of all treating physicians with their contact information, copies of your most recent medical records, and a current list of medications. If you have received any prior denial notices, bring those as well. Expect your interview with a claims representative to last between 45 and 90 minutes.
Avoid delays by ensuring your work history is exhaustive and accurate, as gaps can stall your initial review. Provide recent medical records to avoid the office having to request them from providers, which slows down your process. Do not overlook mental health conditions in your application, as these are as relevant as physical injuries. Read every form thoroughly before signing to ensure the information you provide is complete.
Should you bring an attorney?
The application stage is the foundation of your entire disability claim. Many people apply without guidance and only seek help after a denial, which makes the appeal process significantly more difficult. An attorney can help you organize your medical evidence and ensure your application is complete from the start. A free case review can help you understand your options before you head to the Lancaster office.
