In previous posts, I have mentioned the importance of documentation in submitting a claim for SSD benefits. While documentation is important for SSD claims for physical disabilities, it is even more vital for claims based on mental disabilities like depression. For physical disabilities, most documentation needs to come from the notes of a treating physician, imaging studies, and labs. For SSD claims based on mental disability due to conditions such as depression, however, the medical record is only part of the documentation necessary. While results of psychological testing and the impression of a medical professional are important, information from non-medical sources are also critical to a successful claim. For example, information from the claimant himself, family members, friends, and coworkers can substantially supplement the record and verify the findings of the medical record. Equally important is to present this evidence from various sources over as long a period of time as possible. Such longitudinal evidence will better establish the severity and extent of your functional impairment. Much of this information needs to be properly and effectively presented in the initial application. Many of my clients have come to me after being rejected for an SSD claim despite actually meeting a medical listing for depression solely because they did not include all the appropriate evidence in their applications. As I mentioned before, including all the appropriate evidence from the beginning can mean the difference between receiving SSD benefits and dealing with a frustrating rejection from the SSA. If you are not sure what to include in your application, seek the assistance of a knowledgeable, experienced attorney in your area.
