Application

• Apply for Social Security Disability as soon as possible after you discover that you are unable to work. Many times, the start date for your back payments will begin on the application date.
  
  

Functional Impairments

• With a few exceptions, Social Security Disability is not awarded on the basis of a diagnosis alone (see reference 2). Functional impairments (impairments in functioning with daily tasks, including employment, personal care, etc) are examples, focusing on the ability to maintain employment. Know your functional impairments when applying for disability.
  
  

Medical Records

• Social Security will review your medical records as major part of evaluating whether you qualify as being disabled. You should know your treatment history, all medical providers, and ensure that all necessary records are submitted.
  
  

Current Treatment

• Make sure that you are actively involved in treatment, since this is a factor that will be considered. If you are not involved in treatment, it is likely that your case will be denied, since the argument could be made that you would be able to work if your depression was treated.
  
  

Representation

• You have a right to representation during your appeals process if you are denied after your initial application (see reference 1). Attorneys specializing with Social Security Disability cases are available, and most will charge for their services only after the case is won.
