Social Security sees many applications for disability where anxiety is claimed as either the primary or secondary complaint. Also common are claims of PTSD, panic disorder, OCD, and social anxiety or phobias. But not many cases of anxiety or a related disorder are severe enough to qualify for Social Security disability benefits (SSDI or SSI). Disability benefits are available only to those disability applicants whose anxiety causes a severe impact on their lives: their social functioning, their ability to take care of themselves independently, and their ability to concentrate and complete tasks. The Social Security Administration (SSA) provides guidance as to just how severe anxiety disorder must be, and how it must be documented by the patient's psychologist or psychiatrist, in order for it to render a person eligible for benefits.
