New Immune System Disorder Listings

In our continuing effort to provide information related to Social Security’s new listings on mental impairments we are going to look at changes made to the Immune System Disorder listings. And, as just a reminder, Social Security’s set of listings are used in evaluating disability claims judging a condition’s severity and how it limits a person’s ability to function. This new listing went into effect earlier this year.

  1. What disorders do we evaluate under the immune system disorders listings?
  2. We evaluate immune system disorders that cause dysfunction in one or more components of your immune system.
  3. The dysfunction may be due to problems in antibody production, impaired cell-mediated immunity, a combined type of antibody/cellular deficiency, impaired phagocytosis, or complement deficiency.
  4. Immune system disorders may result in recurrent and unusual infections, or inflammation and dysfunction of the body’s own tissues. Immune system disorders can cause a deficit in a single organ or body system that results in extreme (that is, very serious) loss of function. They can also cause lesser degrees of limitations in two or more organs or body systems, and when associated with symptoms or signs, such as severe fatigue, fever, malaise, diffuse musculoskeletal pain, or involuntary weight loss, can also result in extreme limitation.
  5. We organize the discussions of immune system disorders in three categories: Autoimmune disorders; Immune deficiency disorders, excluding human immunodeficiency virus (HIV) infection; and HIV infection.
  6. Autoimmune disorders (14.00D). Autoimmune disorders are caused by dysfunctional immune responses directed against the body’s own tissues, resulting in chronic, multisystem impairments that differ in clinical manifestations, course, and outcome. They are sometimes referred to as rheumatic diseases, connective tissue disorders, or collagen vascular disorders. Some of the features of autoimmune disorders in adults differ from the features of the same disorders in children.
  7. Immune deficiency disorders, excluding HIV infection (14.00E). Immune deficiency disorders are characterized by recurrent or unusual infections that respond poorly to treatment, and are often associated with complications affecting other parts of the body. Immune deficiency disorders are classified as either primary (congenital) or acquired. Individuals with immune deficiency disorders also have an increased risk of malignancies and of having autoimmune disorders.
  8. Human immunodeficiency virus (HIV) infection (14.00F). HIV infection may be characterized by increased susceptibility to common infections as well as opportunistic infections, cancers, or other conditions listed in 14.11.
  9. What information do we need to show that you have an immune system disorder? Generally. we need your medical history, a report(s) of a physical examination, a report(s) of laboratory findings, and in some instances, appropriate medically acceptable imaging or tissue biopsy reports to show that you have an immune system disorder. Therefore, we will make every reasonable effort to obtain your medical history, medical findings, and results of laboratory tests. We explain the information we need in more detail in the sections below.
  10. Definitions                                                                                                           
  11. Appropriate medically acceptable imaging includes, but is not limited to, angiography, x-ray imaging, computerized axial tomography (CAT scan) or magnetic resonance imaging (MRI), with or without contrast material, myelography, and radionuclear bone scans. “Appropriate” means that the technique used is the proper one to support the evaluation and diagnosis of the impairment.
  12. Constitutional symptoms or signs, as used in these listings, means severe fatigue, fever, malaise, or involuntary weight loss. Severe fatigue means a frequent sense of exhaustion that results in significantly reduced physical activity or mental function. Malaise means frequent feelings of illness, bodily discomfort, or lack of well-being that result in significantly reduced physical activity or mental function.
  13. Disseminated means that a condition is spread over a considerable area. The type and extent of the spread will depend on your specific disease.
  14. Dysfunction means that one or more of the body regulatory mechanisms are impaired, causing either an excess or deficiency of immunocompetent cells or their products.
  15. Extra-articular means “other than the joints”; for example, an organ(s) such as the heart, lungs, kidneys, or skin.
  16. Inability to ambulate effectively has the same meaning as in 1.00B2b.
  17. Inability to perform fine and gross movements effectively has the same meaning as in 1.00B2c.
  18. Major peripheral joints has the same meaning as in 1.00F.
  19. Persistent means that a sign(s) or symptom(s) has continued over time. The precise meaning will depend on the specific immune system disorder, the usual course of the disorder, and the other circumstances of your clinical course.
  20. Recurrent means that a condition that previously responded adequately to an appropriate course of treatment returns after a period of remission or regression. The precise meaning, such as the extent of response or remission and the time periods involved, will depend on the specific disease or condition you have, the body system affected, the usual course of the disorder and its treatment, and the other facts of your particular case.
  21. Resistant to treatment means that a condition did not respond adequately to an appropriate course of treatment. Whether a response is adequate or a course of treatment is appropriate will depend on the specific disease or condition you have, the body system affected, the usual course of the disorder and its treatment, and the other facts of your particular case.
  22. Severe means medical severity as used by the medical community. The term does not have the same meaning as it does when we use it in connection with a finding at the second step of the sequential evaluation processes in §§ 404.1520, 416.920, and 416.924.
