Valid for Submission
D83.9 is a billable diagnosis code used to specify a medical diagnosis of common variable immunodeficiency, unspecified. The code D83.9 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code D83.9 might also be used to specify conditions or terms like common variable agammaglobulinemia or deficiency in anterior pituitary function, variable immunodeficiency syndrome.
Unspecified diagnosis codes like D83.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
Index to Diseases and Injuries
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code D83.9 are found in the index:
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Common variable agammaglobulinemia
- Deficiency in anterior pituitary function, variable immunodeficiency syndrome
- COMMON VARIABLE IMMUNODEFICIENCY-. heterogeneous group of immunodeficiency syndromes characterized by hypogammaglobulinemia of most isotypes variable b cell defects and the presence of recurrent bacterial infections.

Convert D83.9 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code D83.9 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.

Immune System and Disorders
Your immune system is a complex network of cells, tissues, and organs that work together to defend against germs. It helps your body to recognize these "foreign" invaders. Then its job is to keep them out, or if it can't, to find and destroy them.
If your immune system cannot do its job, the results can be serious. Disorders of the immune system include
- Allergy and asthma - immune responses to substances that are usually not harmful
- Immune deficiency diseases - disorders in which the immune system is missing one or more of its parts
- Autoimmune diseases - diseases causing your immune system to attack your own body's cells and tissues by mistake

Common variable immune deficiency Common variable immune deficiency (CVID) is a disorder that impairs the immune system. People with CVID are highly susceptible to infection from foreign invaders such as bacteria, or more rarely, viruses and often develop recurrent infections, particularly in the lungs, sinuses, and ears. Pneumonia is common in people with CVID. Over time, recurrent infections can lead to chronic lung disease. Affected individuals may also experience infection or inflammation of the gastrointestinal tract, which can cause diarrhea and weight loss. Abnormal accumulation of immune cells causes enlarged lymph nodes (lymphadenopathy) or an enlarged spleen (splenomegaly) in some people with CVID. Immune cells can accumulate in other organs, forming small lumps called granulomas.Approximately 25 percent of people with CVID have an autoimmune disorder, which occurs when the immune system malfunctions and attacks the body's tissues and organs. The blood cells are most frequently affected by autoimmune attacks in CVID; the most commonly occurring autoimmune disorders are immune thrombocytopenia, which is an abnormal bleeding disorder caused by a decrease in cells involved in blood clotting called platelets, and autoimmune hemolytic anemia, which results in premature destruction of red blood cells. Other autoimmune disorders such as rheumatoid arthritis can occur. Individuals with CVID also have a greater than normal risk of developing certain types of cancer, including a cancer of immune system cells called non-Hodgkin lymphoma and less frequently, stomach (gastric) cancer.People with CVID may start experiencing signs and symptoms of the disorder anytime between childhood and adulthood; most people with CVID are diagnosed in their twenties or thirties. The life expectancy of individuals with CVID varies depending on the severity and frequency of illnesses they experience. Most people with CVID live into adulthood.There are many different types of CVID that are distinguished by genetic cause. People with the same type of CVID may have varying signs and symptoms.
