Common variable immunodeficiency (D83)
ICD-10 code D83 is used to classify common variable immunodeficiency (CVID), a group of immune system disorders characterized by low antibody levels and increased susceptibility to infections. This section includes specific codes to identify different immunologic abnormalities within CVID.
The codes under D83 capture variations such as CVID with predominant B-cell issues (D83.0), which includes conditions like B-cell immunodeficiency and related syndromes with symptoms like periodic fever and developmental delay. D83.1 covers CVID with mainly T-cell immunoregulatory disorders, while D83.2 identifies cases where autoantibodies attack B- or T-cells. Other types are specified by D83.8, and when the exact immune defect isn’t clear, D83.9 is used. These distinctions aid medical coders in accurately capturing the patient's immune dysfunction, facilitating targeted treatment and research. Using the ICD-10 code for common variable immunodeficiency helps ensure precise documentation of this complex immune disorder and its subtypes.

Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
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.
