There is a great deal of information required on your application for Social Security Disability. You may be somewhat intimidated by the process. In looking over the requirements for the application, even if you were in good health with no physical or mental issues, it could be difficult. If you are ill, have a chronic medical condition or mental impairments that have worsened to the point where you can no longer work, the prospect of putting together all of the necessary information can be especially challenging.
The Social Security Administration (SSA) attempts to be helpful. They have much information on their website that explains the various parts of the process, from the initial application to the appeals process. But if you are not familiar with bureaucratic processes like that of SSA, much of disability benefits process can be confusing.
Remember, SSD is a separate program from any other disability that you may be eligible for such as workers' compensation or an employer-provided disability insurance coverage. To be eligible for SSD benefits, you must first qualify under the statutory definition that SSA uses to determine disability. So even if your doctor states you are "disabled," your impairing condition may not be sufficient to qualify as a disability for purposes of SSD benefits.
The SSD law requires that:
"You must be unable to do any substantial work because of your medical condition(s); and your medical condition(s) must have lasted, or be expected to last, at least 1 year, or be expected to result in your death."
Because "substantial work" also as a specific meaning, you may find it helpful to work with an attorney during your application process or if you need to appeal a denial. But do not let the administrative difficulties of applying for SSD stop your application. If you have a disabling condition that meets the program's requirements, the benefits are worth your effort.
